## Crie um Schema com cada tipo explicado, inserindo tanto um objeto correto, como um objeto que desencadeie erros de validação padrão, criar especificamente:
* 1.1. para String: `enum`, `match`, `maxlength` e `minlength`
* 1.2. para Number: `max` e `min`
**Schema Correto**
```js
'use strict';
const _schema = {
validate_match: { type: String, match: /^a/i }
, validate_enum: { type: String, enum: ['oi', 'tudo', 'bem', 'sim', 'nao'] }
, validate_maxlength: { type: String, maxlength: 15 }
, validate_minlength: { type: String, minlength: 5 }
, validate_max: { type: Number, max: 5 }
, validate_min: { type: Number, min: 3 }
}
, testSchema = new Schema(_schema)
, TestModel = mongoose.model('testValidate', testSchema)
;
let dataModel = {
validate_match: 'Aloca'
, validate_enum: 'bem'
, validate_maxlength: 'eh'
, validate_minlength: 'nois que voa bruxao'
, validate_max: 3
, validate_min: 10
}
, testing = new TestModel(dataModel)
;
testing.save(function(err, data){
if(err) return console.log('Error: ', err);
console.log('Passou nas validações! ', data);
});
// Output do terminal
Passou nas validações! { _id: 56ba956cc043d716eee48366,
validate_min: 10,
validate_max: 3,
validate_minlength: 'nois que voa bruxao',
validate_maxlength: 'eh',
validate_enum: 'bem',
validate_match: 'Aloca',
__v: 0 }
```
**Schema Incorreto**
```js
{ [ValidationError: testValidate validation failed]
message: 'testValidate validation failed',
name: 'ValidationError',
errors:
{ validate_min:
{ [ValidatorError: Path `validate_min` (1) is less than minimum allowed value (3).]

validate_enum:
{ [ValidatorError: `incorreto` is not a valid enum value for path `validate_enum`.]
properties: [Object],
message: '`incorreto` is not a valid enum value for path `validate_enum`.',
name: 'ValidatorError',

properties: [Object],
message: 'Path `validate_match` is invalid (bbbb).',
name: 'ValidatorError',
kind: 'regexp',

value: 'bbbb' } } }
```
## Cadastre 3 pokemons **de uma só vez**:
```js
const _schema = {
name: String
}
, testSchema = new Schema(_schema)
, TestModel = mongoose.model('testInsercao', testSchema)
;
let dataModel = [
{
name: 'Poke-01'

];
TestModel.create(dataModel, function(err, data){
if(err) return console.log('Error: ', err);
console.log('Inseriu todos pokemons! :D ', data);
});
// Output do terminal \\
Inseriu todos pokemons! :D [ { _id: 56bb44b415f642bdf1182962, name: 'Poke-01', __v: 0 },

{ _id: 56bb44b415f642bdf1182964, name: 'Poke-03', __v: 0 } ]
```
## Busque **todos** os Pokemons com `attack > 50` e `height > 0.5`:
```js
const _schema = {

}
, pokemonSchema = new Schema(_schema)
, PokemonModel = mongoose.model('Pokemon', pokemonSchema)
;
function callback(err, data){
if(err) return console.log('Error: ', err);

_id: 566a25407d0b654cdf58b763 } ]
```
## Altere, **inserindo**, o Pokemon `Nerdmon` com `attack` igual a 49 e com os valores dos outros campos a sua escolha.
```js
const _schema = {

# 1) Crie um Schema com cada tipo especificado, inserindo tanto um objeto correto, como um objeto que desencadeie erros na validação padrão, criar especificamente:
- para String: **enum**, **match**, **maxlength**, **minlength**
- para Number: **max** e **min**
Objeto correto:
```
'use strict';
const dbUri = 'mongodb://127.0.0.1/pokemon';
const mongoose = require('mongoose');
mongoose.connect(dbUri);
var Schema = mongoose.Schema;
var pokemonSchema = new Schema({
name: { type: String, maxlength: 10, minlength: 4, enum: ['Pikachu', 'Beedril', 'Beedril2'], match: /^[a-z]+$/i },
attack: {type: Number, max: 100, min: 0},
created: {type: Date, default: Date.now},
isDead: Boolean,
moves: [String],
children: Schema.Types.Mixed,
id: Schema.Types.ObjectId
});
var model = mongoose.model('pokemon', pokemonSchema);
var pokeModel = new model({
name: 'Pikachu',
attack: 50
});
pokeModel.save(pokeModel, function (err, data) {
if (err) console.log(err);
console.log(data);
});
```
Agora os erros de validação...
**erro de max e maxlength**
```
{ [ValidationError: Pokemon validation failed]

name: 'ValidatorError',
kind: 'maxlength',
path: 'name',
value: 'Pikachuzzzzzzz' } } }
undefined
```
**erro de min e minlength**
```
{ [ValidationError: Pokemon validation failed]
message: 'Pokemon validation failed',
name: 'ValidationError',
errors:
{ attack:
{ [ValidatorError: Path `attack` (-20) is less than minimum allowed value (0).]
properties: [Object],

message: 'Path `name` (`c`) is shorter than the minimum allowed length (4).',
name: 'ValidatorError',
kind: 'minlength',
path: 'name',

undefined
```
**erro de enum**
```
{ [ValidationError: Pokemon validation failed]

value: -20 },
name:
{ [ValidatorError: `csdsss` is not a valid enum value for path `name`.]
properties: [Object],
message: '`csdsss` is not a valid enum value for path `name`.',
name: 'ValidatorError',
kind: 'enum',
path: 'name',
value: 'csdsss' } } }
undefined
```
**erro de match**
```
{ [ValidationError: pokemon validation failed]
message: 'pokemon validation failed',

undefined
```
# 2) Cadastre 3 Pokemons de uma só vez:
```
var Schema = mongoose.Schema;
var pokemonSchema = new Schema({
name: String,
attack: Number,
created: {type: Date, default: Date.now},
isDead: Boolean,

});
var model = mongoose.model('pokemon', pokemonSchema);
var pokeOne = new model({

attack: 101
});
var pokeTwo = new model({
name: 'Pikamole',
attack: 19

attack: 69
});
var pokemons = [pokeOne, pokeTwo, pokeFour];
model.create(pokemons, function (err, data) {
if (err) console.log(err);
console.log(data);
});
```
# 3) Busque todos os pokemons com attack > 50 e height > 0.5
```
var model = mongoose.model('pokemon', pokemonSchema);
var query = { attack: { $gt: 50 }, height: {$gt: 50}}
model.find(query, function (err, data) {
if (err) console.log(err);
console.log(data);
})
```
# 4) Altere, inserindo, o Pokemon Nerdmon com attack = 49 e com os valores de outro campo de sua escolha.
```
var model = mongoose.model('pokemon', pokemonSchema);
var query = { attack: 49, name: 'Nerdmon' };
model.update(query, query, { upsert: true }, function (err, data) {
if (err) console.log(err);
console.log(data);
})
```
# 5) Remova todos os Pokemons com attack > 50.
```
var model = mongoose.model('pokemon', pokemonSchema);
var query = { attack: {$gt: 50} };
model.remove(query, function (err, data) {
if (err) console.log(err);

## Crie um Schema com cada tipo explicado, inserindo tanto um objeto correto, como um objeto que desencadeie erros de validação padrão, criar especificamente:
* 1.1. para String: `enum`, `match`, `maxlength` e `minlength`
* 1.2. para Number: `max` e `min`
### Definção do _schema_ com validações
```js
// validacao do formato de email - validate
const validateEmail = function(email) {
let re = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/;
return re.test(email);
};
// regex para verificar se a imagem possui extensao .jpg (validacao match)
const matchFoto = [ /\.jpg$/, "A imagem não possui extensão .jpg ({VALUE})" ];
// regex para verificar se foi informado apenas numeros no telefone (validacao match)
const matchTelefone = [ /^[0-9]*$/, "Informe apenas números para o telefone" ];
const Schema = mongoose.Schema;
// definacao do esquema com as validacoes
const _schema = {
nome: { type: String, minlength: 5, maxlength: 40, required: "O nome é obrigatório" },
idade: { type: Number, min: 10, max: 110 },
operadora: { type: String, enum: ["claro", "vivo", "gvt", "telefonica", "tim"] },
telefone: { type: String, match: matchTelefone, minlength: 8, maxlength: 12, required: "Telefone é obrigatório" },
foto: { type: String, match: matchFoto },
email: { type: String, required: "Email é obrigatório", validate: [validateEmail, "Informe um e-mai válido!"] }
};
```
### Script completo para simular a inserção de um objeto de forma _INCORRETA_
```js
"use strict";
const mongoose = require("mongoose");
const dbURI = "mongodb://localhost/agenda";
mongoose.connect(dbURI);
const validateEmail = function(email) {
let re = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/;
return re.test(email);
};
const matchFoto = [ /\.jpg$/, "A imagem não possui extensão .jpg ({VALUE})" ];
const matchTelefone = [ /^[0-9]*$/, "Informe apenas números para o telefone" ];
const Schema = mongoose.Schema;
const _schema = {
nome: { type: String, minlength: 5, maxlength: 40, required: "O nome é obrigatório" },
idade: { type: Number, min: 10, max: 110 },
operadora: { type: String, enum: ["claro", "vivo", "gvt", "telefonica", "tim"] },
telefone: { type: String, match: matchTelefone, minlength: 8, maxlength: 12, required: "Telefone é obrigatório" },
foto: { type: String, match: matchFoto },
email: { type: String, required: "Email é obrigatório", validate: [validateEmail, "Informe um e-mai válido!"] }
};
const ContatoSchema = new Schema(_schema);
const Contatos = mongoose.model("contatos", ContatoSchema);
const dados = {
nome: "Fulano da Silva",
idade: 77,
operadora: "vivo",
telefone: "4799999999",
foto: "imagem.gif",
email: "fulano_da_silva@gmail.com"

"use strict";
const mongoose = require("mongoose");
const dbURI = "mongodb://localhost/be-mean-instagram";
mongoose.connect(dbURI);
const Schema = mongoose.Schema;
const _schema = {

```
## Busque **todos** os Pokemons com `attack > 180` e `speed > 70`:
### Teste no console do MongoDB
```
// todos os pokemons
db.pokemons.count();
613
// definicao do filtro
var query = { attack: { $gt:180 }, speed: { $gt: 70 } };
// retorna a quantidade apos aplicacao do filtro
db.pokemons.count(query);
2
```
### Teste com o nodeJS - _SCRIPT_
```js
"use strict";
const mongoose = require("mongoose");
const dbURI = "mongodb://localhost/be-mean-instagram";
mongoose.connect(dbURI);
const Schema = mongoose.Schema;
const _schema = {};
const pokemonSchema = new Schema(_schema);
const PokemonModel = mongoose.model("pokemons", pokemonSchema);
const query = {attack: { $gt: 180 }, speed: { $gt: 70 } };
PokemonModel.find(query, (err, data) => {
if (err) return console.log("ERRO: ", err);
return console.log("Buscou: ", data);
});
```
### Teste com o nodeJS - _RESULTADO_
```js
[nodemon] starting `node aula06_03.js`
Buscou: [ { types: [ 'fighting', 'psychic' ],
speed: 130,
name: 'Mewtwo-mega-x',
hp: 106,
height: '0',
defense: 100,
created: '2013-11-03T15:05:42.554794',
attack: 190,
_id: 564b1de525337263280d06a2 },
{ types: [ 'fighting', 'bug' ],
speed: 75,

attack: 185,
_id: 564b1de525337263280d06a6 } ]
```
## Altere, **inserindo**, o Pokemon `Nerdmon` com `attack` igual a 49 e com os valores dos outros campos a sua escolha.
### Confirmando no console do MongoDB que não há o Nerdmon já inserido
```
var query = { name: /Nerdmon/ };
db.pokemons.find(query);
Fetched 0 record(s) in 1ms
```
### Script
```js
"use strict";
const mongoose = require("mongoose");
const dbURI = "mongodb://localhost/be-mean-instagram";
mongoose.connect(dbURI);
const Schema = mongoose.Schema;
const _schema = {
"attack": Number,
"created": Date,
"defense": Number,
"height": String,
"name": String,
"speed": Number,
"types": [String]
};
const PokemonSchema = new Schema(_schema);
const Pokemon = mongoose.model("pokemons", PokemonSchema);
const query = { name: /Nerdmon/ };
const mod = {
$setOnInsert: {
"name": "Nerdmon",
"attack": 49,
"created": new Date(),
"defense": 80,
"height": "56",
"speed": 99,
"types": ["water", "flash", "ghost"] }
};
const options = {upsert: true};
Pokemon.update(query, mod, options, (err, data) => {
if (err) return console.log("ERRO: ", err);
console.log("Criou o Nerdmon com upsert: ", data);
});
```
### Resultado da execução do script no nodeJS
```
Criou o Nerdmon com upsert: { ok: 1,
nModified: 0,
n: 1,
upserted: [ { index: 0, _id: 5760db14ec918dcbc3f73da7 } ] }
```
### Consulta no console do MongoDB:
```js
var query = { name: /Nerdmon/ };
db.pokemons.find(query);
{
"_id": ObjectId("5760db14ec918dcbc3f73da7"),
"name": "Nerdmon",
"attack": 49,
"created": ISODate("2016-06-15T04:35:32.133Z"),
"defense": 80,
"height": "56",
"speed": 99,
"types": [
"water",
"flash",
"ghost"
]
}
Fetched 1 record(s) in 2ms
```
## Remova **todos** os Pokemons com `attack` **acima de 50**.
### Verifica no console do MongoDB a quantidade total de pokemons com attack acima de 50 antes da exclusão
```
var query = { attack: { $gt: 50 } };
db.pokemons.count(query);
465
```
### Script
```js
"use strict";
const mongoose = require("mongoose");
const dbURI = "mongodb://localhost/be-mean-instagram";
mongoose.connect(dbURI);
const Schema = mongoose.Schema;
const _schema = {};
const PokemonSchema = new Schema(_schema);
const Pokemon = mongoose.model("pokemons", PokemonSchema);
const query = { attack: { $gt: 50 } };
Pokemon.remove(query, (err, data) => {
if (err) return console.log("ERRO: ", err);
console.log("Removeu os pokemons com ataque acima de 50: ", data);
});
```

##### [Exercício-05](#remova-todos-os-pokemons-com-attack-acima-de-50)
## Crie um Schema com cada tipo explicado, inserindo tanto um objeto correto, como um objeto que desencadeie erros de validação padrão, criar especificamente:
* Number: possui os validadores de `max` e `min`
* String: possui os validadores de `enum`, `match`, `maxlength` e `minlength`
```js
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const _schema = {
name: {type: String, match: /^./i }
, age: {type: Number, min: 15}
, gender: {type: String, enum: ['M', 'F']}
, city: {type: String, maxlength: 10}
, state: {type: String, minlength: 2}
}
// Criação do Schema
const pokemonSchema = new Schema(_schema);
const data = {
name: '2D Lima',
age: 28,
gender: 'M',
city: 'Pallet',
state: 'PL'
}
const Model = mongoose.model('pokemons', pokemonSchema);
const poke = new Model(data);
poke.save(function (err, data) {
if (err) return console.log('ERRO: ', err);
console.log('Inseriu: ', data)
})
module.exports = pokemonSchema;
```
#### Saída
```

## 1. Crie um schema com cada tipo explicado, inserindo tanto um objeto correto, como um objeto que desencadeie erro de validação padrão, criar especificamente:
### 1.1 para String: enum, match, maxlength e minlength
### 1.2 para Number: max e min
##### Inserção correta
```js
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const schemaObj = {
string : {
type : String,
enum : ['string', 'não string'],
match : [/string/i, 'Não foi encontrada a palavra string 1'],
maxlength : [7, 'String muito grande'],
minlength: [2, 'String muito curta']
},
boolean : {
type : Boolean
},
number : {
type : Number,
max : [10, 'Numero muito grande'],
min : [2, 'Numero muito pequeno']
},
array : {
type : [String]
},
date : {
type : Date
},
objectID : {
type : Schema.Types.ObjectId
},
mixed : {
type : Schema.Types.Mixed
}
};
const schemaTest = new Schema(schemaObj);
const Correto = {
string : 'string',
boolean : true,
number : 4,
array : ['Paulo', 'Silva'],
date : Date.now(),
objectID : ['56e4d08d45228b2a7019d969'],
mixed : [{name : 'obj1'}, {name : 'obj2'}]
};
const Model = mongoose.model('model',schemaTest);
const modelTeste = new Model(Correto);
modelTeste.save((err, data)=>{
if(err) return console.log('Erro ',err);
console.log('Foi ',data);
});
```
##### Resultado
```js
Foi { array: [ 'Paulo', 'Silva' ],
_id: 56e4da30cfbc315979eaeed2,

number: 4,
boolean: true,
string: 'string',
__v: 0 }
```
##### Inserção com erros
```js
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const schemaObj = {
string : {
type : String,
enum : ['string', 'não string'],
match : [/string/i, 'Não foi encontrada a palavra string 1'],

const schemaTest = new Schema(schemaObj);
const Incorreto = {
string : 'stringnumero2',
boolean : true,

const Model = mongoose.model('model',schemaTest);
const modelTeste = new Model(Incorreto);
modelTeste.save((err, data)=>{
if(err) return console.log('Erro ',err);
console.log('Foi ',data);
});
```
##### Resultado
```js

> A organização de códigos utilizadas nas aulas de Node.js utilizando `app.js` e `config.js` será usada nos exercícios daqui em diante.
## Resumo da Aula
=============
Ao termino dessas aulas pude chegar a concluir que:
<br>
Utilizado na programação com NodeJS, o Mongoose é quem será o responsável por gerenciar schemas do nosso banco de dados. É uma ferramenta do MongoDB para modelagem de objetos projetados para trabalhar em um ambiente assíncrono. Para definir uma conexão é necessário utilizaro `mongoose.connect` e caso para a criação de conexões adicionais é simples utilizando o `mongoose.createConnection`.
```js
const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/meu-banco-de-dados');
```
E ele possue 4 tipos de eventos:
- error: quando acontece um erro
- connected: quando conectamos com o MongoDb
- open: quando a conexão foi aberta com o MongoDb
- disconnected: quando o MongoDb é desconectado da nossa aplicação
```js
mongoose.connection.on('connected', () => {
console.log(`Mongoose default connection open to ${dbURI}`);
});
mongoose.connection.on('error',err => {
console.log(`Mongoose default connection error: ${err}`);
});
mongoose.connection.on('disconnected', () => {
console.log('Mongoose default connection disconnected');
});
mongoose.connection.on('open', () => {
console.log('Mongoose default connection is open');
});
```
Por último para fechar a conexão usaremos o `process.on` com o evento `SIGINIT`
```js
process.on('SIGINT', () => {
mongoose.connection.close(() => {
console.log('Mongoose default connection disconnected through app termination');
process.exit(0);
});
});
```
## Exercicio-01
=============
> Crie um schema com cada tipo explicado inserindo tanto um objeto correto como um objeto que desencadeie erros de validação padrão criar especificamente:
* 1.1. para String: `enum`, `match`, `maxlength` e `minlength`
* 1.2. para Number: `max` e `min`
## Schema-correto
```js
'use strict';
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const pokemonSchema = new Schema({
name: {type: String, match: /^(\D)*$/g},
password: {type: String, minlength: 8},
description: {type: String, maxlength: 20},
type: {type: String, enum: ['Water', 'Fire', 'Stone', 'Bug', 'People']},
attack: {type: Number, min: 30},
defense: {type: Number, max: 70},
hasSpecial: {type: Boolean, required: true},
skills: [String],
created_at: {type: Date, default: Date.now},
relatedTo: [{type: Schema.Types.ObjectId, ref: 'pokemons'}]
});
const PokemonModel = mongoose.model('pokemons', pokemonSchema);
let poke = new PokemonModel({
name: 'Suissa',
password: 'gatinhoslindosefos',
description: 'Pokemon do KCT',
type: 'People',
attack: 100,
defense: 45,
hasSpecial: true,
skills: ['js','ensinar', 'fumar']
});
poke.validate((err, data) => {
if (err) return console.log(err);
console.log('Objeto validado com sucesso');
});
```
Resultado:
```bash
{}
Objeto validado com sucesso
Mongoose default connection connected to mongodb://localhost/be-mean-instagram
Mongoose default connection is open
```
## Schema-Incorreto
```js
let poke = new PokemonModel({
name: 'Suissa',
password: 'gatinhoslindosefos',
description: 'um pokémon que ama seus amigos e, bla bla bla bla',
type: 'Adorador de Gatos',
attack: 10,
defense: 100,
skills: true
});
```
Resultado:
```js

## Crie um Schema com cada tipo explicado, inserindo tanto um objeto correto, como um objeto que desencadeie erros de validação padrão, criar especificamente:
* para string: enum, match, maxlenght e minlenght
* para Number: min e max
### Código com erros de validação:
/*
* Testing validation of various Schema Types
*/
'use strict';
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
let weekdays = ['monday', 'tuesday', 'wednesday', 'thursday',
'friday'];
// Schema validations
let _schema = new Schema({
vString: { type: String },
vStringMatch : {type: String, match: /^(mon|tue|wed|thu|fri)day$/i},
vStringEnum: { type: String, enum: weekdays },
vStringMinMaxLength: { type: String, minlength: 1, maxlength: 8 },
vNumber: { type: Number, min: 13, max: 19 },
vBoolean: { type: Boolean },
vDate: { type: Date },
vObjectId: Schema.Types.ObjectId,
vMixed: Schema.Types.Mixed
});
let pokeModel = mongoose.model('Pokemons', _schema);
let poke = new pokeModel;
// Validating with errors
poke.vString = {};
poke.vStringMatch = 'ang';

poke.vObjectId = 'only objectId here';
poke.save( (err, data) => {
if (err) {
return console.error(err);
}
console.log('Data entered in the database:' + data);
});
### Resultados com erros de validação:
PS C:\Projetos\mongoose-pokemons> node app

# Node.js - Aula 06 - Exercício
**user:** [ednilsonamaral](https://github.com/ednilsonamaral)
**autor:** Ednilson Amaral
## Crie um Schema com cada tipo explicado, inserindo tanto um objeto correto, como um objeto que desencadeie erros de validação padrão, criar especificamente:
* 1.1. para String: `enum`, `match`, `maxlength` e `minlength`
* 1.2. para Number: `max` e `min`
No banco *be-mean-instagram* estou pedindo para criar uma nova *collection*, chamada `alunos`.
No JS abaixo, eu inseri na *collection* um objeto correto.
```js
require('./config.js');
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const aluno = {
//o match aceita regex, no caso abaixo, o nome pode ser case insensitive e começar com qualquer caractere
nome: {type: String, match: /^./i },
//max serve para setar o campo para que seja inserido um número máximo, no caso no máximo até 30, se não dá erro
idade: {type: Number, max: 30},
//o enum irá setar o sexo do cara, Masculino ou Feminino
sexo: {type: String, enum: ['M', 'F']},
//a ideia desse campo é que o aluno tenho no mínimo 5 aulas, caso contrário dá erro
aulas: {type: Number, min: 5},
//o nome da cidade deve conter no máximo 10 caracteres
cidade: {type: String, maxlength: 10},
//o nome do estado deve conter no mínimo 2 caracteres
estado: {type: String, minlength: 2}
}
const alunoSchema = new Schema(aluno);
const AlunoModel = mongoose.model('alunos', alunoSchema);
const data = (
{
nome: 'Ednilson',
idade: 24,
sexo: 'M',
aulas: 16,
cidade: 'Itapeva',
estado: 'SP'
}
);
const Ednilson = new AlunoModel(data);
Ednilson.save(function (err, data) {
if (err) return console.log('Erro: ', err);
console.log('Inserido o aluno: ', data);
});
```
A saída no *nodemon* foi a seguinte:
```
Inserido o aluno: { _id: 56ac40f7dd143b141efb4685,
estado: 'SP',
cidade: 'Itapeva',
aulas: 16,
sexo: 'M',
idade: 24,
nome: 'Ednilson',
__v: 0 }
```
Agora, no JS abaixo, é o objeto com erros de validação padrão:
```js
require('./config.js');
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const aluno = {
//o match aceita regex, no caso abaixo, o nome pode ser case insensitive e começar com qualquer caractere
nome: {type: String, match: /^./i },
//max serve para setar o campo para que seja inserido um número máximo, no caso no máximo até 30, se não dá erro
idade: {type: Number, max: 30},
//o enum irá setar o sexo do cara, Masculino ou Feminino
sexo: {type: String, enum: ['M', 'F']},
//a ideia desse campo é que o aluno tenho no mínimo 5 aulas, caso contrário dá erro
aulas: {type: Number, min: 5},
//o nome da cidade deve conter no máximo 10 caracteres
cidade: {type: String, maxlength: 10},
//o nome do estado deve conter no mínimo 2 caracteres
estado: {type: String, minlength: 2}
}
const alunoSchema = new Schema(aluno);
const AlunoModel = mongoose.model('alunos', alunoSchema);
const data = (
{
nome: 'Aline',
idade: 31,
sexo: 'J',
aulas: 3,
cidade: 'São Carlos',
estado: 'SP'
}
);
const Ednilson = new AlunoModel(data);
Ednilson.save(function (err, data) {
if (err) return console.log('Erro: ', err);
console.log('Inserido o(a) aluno(a): ', data);
});
```
E a saída no *nodemon* foi a seguinte:
```
Erro: { [ValidationError: alunos validation failed]
message: 'alunos validation failed',
name: 'ValidationError',
errors:
{ aulas:
{ [ValidatorError: Path `aulas` (3) is less than minimum allowed value (5).]
properties: [Object],

kind: 'min',
path: 'aulas',
value: 3 },
sexo:
{ [ValidatorError: `J` is not a valid enum value for path `sexo`.]
properties: [Object],
message: '`J` is not a valid enum value for path `sexo`.',
name: 'ValidatorError',
kind: 'enum',
path: 'sexo',
value: 'J' },
idade:
{ [ValidatorError: Path `idade` (31) is more than maximum allowed value (30).]
properties: [Object],
message: 'Path `idade` (31) is more than maximum allowed value (30).',
name: 'ValidatorError',
kind: 'max',
path: 'idade',
value: 31 } } }

## Cadastre 3 pokemons **de uma só vez**.
Arquivo JS:
```js
require('./config.js');
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const poke = {
name: String,
description: String,
type: String,
attack: Number,
defense: Number,
height: Number
}
const PokemonSchema = new Schema(poke);
const PokemonModel = mongoose.model('pokemons', PokemonSchema);
const data = [
{
name: "Bowlmon",
description: "O pokemon mais viciado em NFL que qualquer extraterreste da Terra",
type: "nflmon",
attack: 98,
defense: 97,
height: 2.1
},
{

},
{

description: "O cabeludo pirado",
type: "nflmon",
attack: 91,
defense: 85,
height: 2
}
];
PokemonModel.create(data, function (err, data) {
if (err) return console.log('Erro: ', err);
console.log('Inserido(s): ', data);
});
```
Executando `node app.js` temos:
```

## Altere, **inserindo**, o Pokemon `Nerdmon` com `attack` igual a 49 e com os valores dos outros campos a sua escolha
O arquivo JS ficou da seguinte maneira:
```js
require('./config.js');
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const poke = {
name: String,
description: String,
type: String,
attack: Number,
defense: Number,
height: Number
}
const PokemonSchema = new Schema(poke);
const PokemonModel = mongoose.model('pokemons', PokemonSchema);
const insere = {
name: "Nerdmon",
description: "O pokemon mais nerd que já existiu, que existe ou que existirá",
type: "nerd",
attack: 999,
defense: 888,
height: 1.8
};
const Model = new PokemonModel(insere);
Model.save(insere, function (err, insere) {
if (err) return console.log('Erro: ', err);
console.log('Inserido: ', insere);
});
const alteraQuery = {name: /nerdmon/i};
const alteraMod = {attack: 49};
PokemonModel.update(alteraQuery, alteraMod, function (err, data){
if (err) return console.log('Erro: ', err);
console.log('Alterado: ', data);
});
```
Ao executar `node app.js` temos:
```

name: 'Nerdmon',
__v: 0 }
Alterado: { ok: 1, nModified: 1, n: 1 }
```
E, por via das dúvidas, consultando no MongoDB, temos:

Por via das dúvidas, no MongoDB, antes de executar o `app.js` busquei quantos tinhas segundo a condição do exercício. Após isso, obtive o número total de objetos salvos e então o *count* após executar o `app.js`.
```
be-mean-pokemons> var query = {attack: {$gt: 50}}
be-mean-pokemons> db.pokemons.count(query)
10
be-mean-pokemons> db.pokemons.count()
15
be-mean-pokemons> db.pokemons.count()
5

# Node.js - Aula 06 - Exercício
autor: Bruno Lima da Silva
## 1. Crie um Schema com cada tipo explicado, inserindo tanto um objeto correto, como um objeto que desencadeie erros de validação padrão, criar especificamente:
### -1.1 para String: enum, match, maxlength e minlength
String enum:
```js
const mongoose = require ('mongoose');
const Schema = mongoose.Schema;
const _schema = {
n: {
type: String,
enum: 'Valid'
}
};
const dataSchema = new Schema (_schema);
const data = { n: 'invalid' };
const model = mongoose.model ('pokemons', dataSchema);
const value = new model (data);
value.save ( (err, data) => {
if (err) return console.log ('ERRO:', err);
return console.log ('Inseriu:', data);
});
```
Saída
```
message: 'pokemons validation failed',
name: 'ValidationError',
errors:
{ n:
{ ValidatorError: `invalid` is not a valid enum value for path `n`.

O quark que utilizei para este exercício foi a validacão do isbn-13, utilizado para livros deste 2007, podendo ajudar quem deseja construir alguma aplicação que catalogue livros ou bibliotecas.
Fonte: https://pt.wikipedia.org/wiki/International_Standard_Book_Number#ISBN-13
>A edição de 2005 do manual oficial do International ISBN Agency,[10] que abrange os ISBNs emitidos a partir de Janeiro de 2007, descreve como é efectuado o calculo, do dígito de verificação, do ISBN de 13 dígitos. O cálculo do dígito de verificação do ISBN-13 começa com os primeiros 12 dígitos dos 13, multiplicando alternadamente por 1 ou 3 , da esquerda para a direita, em seguida, estes produtos são somados módulo 10 para dar um valor que varia de 0 a 9, que subtraído a 10, que deixa um resultado de 1 a 10. Um zero (0) substitui 0 dez (10), garantindo assim, que o resultado da verificação não é maior que um dígito.

# Node.js - Aula 09 - Exercício
**user:** [tuchedsf](https://github.com/tuchedsf)
**autor:** Diego Ferreira
## Parte 1
###1) Faça uma lista de todas as funções que o modulo assert possui e coloque no md.
- assert -> Sinônimo de assert.ok, apenas atesta a existência da variável se é verdadeira.
- assert.deepEqual(atual, esperado, mensagem) -> testa se o valor atual é igual ao valor esperado, e valores primitivos são testados com comparação simples "==".
- assert.deepStrictEqual(atual, esperado, mensagem) -> idêntico ao deepEqual. A única diferença que aqui os valores primitivos são testados com "===", ou seja, além do "valor" também consideram o tipo do valor.
- assert.doesNotThrow(block, error, message) -> verifica se a função passada em "block" não retorna nenhum erro.
- assert.equal(atual, esperado, mensagem) -> verifica se o valor passada como atual é igual ao esperado e em caso de objetos se o objeto atual é igual ao esperado.
- assert.fail(atual, esperado, mensagem, operador) -> O operador serve para separar o elemento atual do esperado, em caso em caso de erro e se a mensagem não estiver preenchida. Caso a mensagem esteja preenchida é exibida a mensagem.
- assert.ifError(value) -> Testa se o valor não é um valor falso e dispara o throws se for verdadeiro.
- assert.notDeepEqual(atual, esperado, mensagem) -> Testa qualquer diferença entre os objetos tanto valor quanto tipo.
- assert.notDeepStrictEqual(atual, esperado, mensagem ) -> Testa se o valor do objeto atual é diferente do esperado porém leva em consideração o tipo de objeto.
- assert.notEqual(atual, esperado, mensagem) -> Testa se o valor do atual é diferente do esperado, leva em consideração o tipo de objeto.
- assert.notStrictEqual(atual, esperado, mensagem) -> Testa se o valor do atual é diferente do esperado, não leva em consideração o tipo de objeto.
- assert.ok(valor, mensagem) -> testa se o valor é verdadeiro.
- assert.strictEqual(atual, esperado, mensagem) -> testa se o valor e tipo do objeto são iguais.
- assert.throws(função[erro], mensagem) -> testa erros em funções.
###2) Modifique todos os testes que estão usando assert.equal para assert.deepStrictEqual(valor, result, "comentario") faça todos passarem, coloque os testes no md. ( primeira parte da aula)
Alteração assert add.spec.js
```js
'use strict';
const assert = require("assert");
const add = require("./assert_add");
//assert.equal(3, add(1,2));
//assert.equal(8, add(1,2,5));
assert.deepStrictEqual(3, add(1,2), "Resultado da soma diferente");
assert.deepStrictEqual(8, add(1,2,5), "Resultado da soma diferente");
```
Resultado:
```
Falha:
MacBook-Air-Diego:9tdd diego$ mocha assert_add_spec.js
assert.js:89
throw new assert.AssertionError({
^
AssertionError: Resultado da soma diferente
Correção:
➜ test mocha assert_add_spec.js
2 passing (4ms)
```
babystep.js
```js
'use strict';
const assert = require('assert');
const log = require('./log');
//assert.equal('Hello World', log('Hello World'));
//assert.equal('final do hello world', log('final do hello world'));
assert.deepStrictEqual('Hello World', log('Hello World'));
assert.deepStrictEqual('final do hello world', log('final do hello world'));
```
Resultado:
```
Erro:
➜ test mocha log_spec.js
assert.js:89
throw new assert.AssertionError({
^
AssertionError: 'Hell World' == 'Hello World'
Correção:
➜ test mocha log_spec.js
2 passing (4ms)
```
###3) Na calculadora do CHAI crie mais 3 testes, um para divisão, outro para multiplicação e 1 para raiz quadrada, lembrando que não deve-se aceitar divisão por zero.
calc.js
```js
'use strict';
const Calc = {
sum : (number1, number2) =>{
return number1 + number2;
}
, subtract : (number1, number2) => {
return number1 - number2;
}
, multiply : (number1, number2) => {
return number1 * number2;
}
, divide : (number1, number2) => {
return number1 / number2;
}
, square : (number) => {
return Math.sqrt(number);
}
};
module.exports = Calc;
```
chai_calc.js
```js
'use strict';
const Calc = require('../calc.js');
const expect = require('chai').expect;
describe("Calc", ()=> {
describe("calc sum off two numbers", () =>{
it("the function return the sum of two numbers", () => {
const sum = Calc.sum(5,5);
expect(sum).to.be.a('number');
expect(sum).to.equal(10);
expect(Calc).to.have.property('sum');
});
});
describe("calc sub off two numbers", () =>{
it("the function return the subtract of two numbers", () => {
const subtract = Calc.subtract(5,5);
expect(subtract).to.be.a('number');
expect(subtract).to.equal(0);
expect(Calc).to.have.property('subtract');
});
});
describe("calc multiply two numbers", () =>{
it("the function return the multiply of two numbers", () => {
const multiply = Calc.multiply(5,5);
expect(multiply).to.be.a('number');
expect(multiply).to.equal(25);
expect(Calc).to.have.property('multiply');
});
});
describe("calc divide two numbers", () =>{
const number1 = 5;
const number2 = 1;
it("the divisor great then 0", () => {
expect(number2).to.be.a('number');
expect(number2).not.to.be.NaN;
expect(number2).to.be.at.least(1);
});
it("the function return the divide of two numbers", () => {
const divide = Calc.divide(5,5);
expect(divide).to.be.a('number');
expect(divide).to.equal(1);
expect(Calc).to.have.property('divide');
});
});
describe("calc square two numbers", () =>{
it("the function return the square of two numbers", () => {
const square = Calc.square(9);
expect(square).to.be.a('number');
expect(square).to.equal(3);
expect(Calc).to.have.property('square');

###4) Use o expect para testar a exceção da divisão por zero. (complemento do exercício 3)
Feito no exercício antetior, abaixo apenas o teste criado para barrar divisão por 0.
```
describe("calc divide two numbers", () =>{
const number1 = 5;
const number2 = 0;
it("the divisor great then 0", () => {
expect(number2).to.be.a('number');
expect(number2).not.to.be.NaN;
expect(number2).to.be.at.least(1);
});
```
##Parte 02
###1) Use o exemplo de testes do getter e setter e crie um teste para o method. use o exemplo: (https://github.com/Webschool-io/be-mean-instagram/blob/master/Apostila%2Fmodule-nodejs%2Fsrc%2Fmongoose-atomic%2Fschema-method.js)
schema.js
```js
'use strict';
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
mongoose.connect('mongodb://localhost/be-mean-instagram');
const _schema = {
name: String
, description: String
, type: String
, attack: Number
, defense: Number
, height: Number
};
const PokemonSchema = new Schema(_schema);
PokemonSchema.methods.findSimilarType = function (cb) {
return this.model('Pokemon').find({ type: this.type }, cb);
};
const Pokemon = mongoose.model('Pokemon', PokemonSchema);
module.exports = Pokemon;
```
schema-method-test.js
```js
'use strict';
const Pokemon = require('../schema-method');
const chai = require('chai');
const expect = chai.expect;
const util = require('util');
describe('Pokemon methods test', ()=>{
const Poke = { name: 'Teste', type: 'besta' };
describe("validate find similar type", ()=> {
it('lista apenas pokemons types iguais', (done) => {
let pokeBusca = new Pokemon({name: 'Besta 2', type: 'besta'});
pokeBusca.findSimilarType((err,data) => {
expect(err).to.not.exist;
expect(data).to.be.instanceof(Array);
data.forEach((pokemon) => expect(pokemon).to.have.property('type').and.equal('besta'));
done();
});
});
});
});
```
Resultado:
```
mocha schema-method-test.js
Pokemon methods test
validate find similar type
✓ lista apenas timos iguais de pokemon
1 passing (60ms)
```
###2) Use o exemplo de testes do getter e setter, o static, use o exemplo: https://github.com/Webschool-io/be-mean-instagram/blob/master/Apostila%2Fmodule-nodejs%2Fsrc%2Fmongoose-atomic%2Fschema-static.js
schema-static.js
```js
'use strict';
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
mongoose.connect('mongodb://localhost/be-mean-instagram');
const _schema = {
name: String
, description: String
, type: String
, attack: Number
, defense: Number
, height: Number
};
const PokemonSchema = new Schema(_schema);
PokemonSchema.statics.search = function (name, cb) {
return this.where('name', new RegExp(name, 'i')).exec(cb);
};
const Pokemon = mongoose.model('Pokemon', PokemonSchema);
module.exports = Pokemon;
```
schema-static-test.js
```js
'use strict';
const Pokemon = require('../schema-static');
const chai = require('chai');
const expect = chai.expect;
const util = require('util');
describe('Pokemon static test', ()=>{
describe("validate find nomes iguais", ()=> {
it('lista pokemons de mesmo nome', (done) => {
Pokemon.search('pikachu', function (err, data) {
expect(err).to.not.exist;
expect(data).to.be.instanceof(Array);
data.forEach((pokemon) => expect(pokemon).to.have.property('name').and.equal('Pikachu'));
done();
});
});
});
});
```
Resultado:
```
mocha schema-static-test.js
Pokemon static test
validate find nomes iguais
✓ lista pokemons de mesmo nome
1 passing (57ms)
```
###3) No controller ainda falta dois métodos para testar, o update e o delete, crie-os e faça os testes, no mesmo arquivo que contem os testes create e retrive.
controller-poke-test.js
```js
'use strict';
const util = require('util');
const chai = require('chai');
const expect = chai.expect;
const pokeController = require('../controller-pokemon');
const Pokemon = require('../schema-static');
describe("Controller User teste", () => {
const poke = {
name: 'Novo Poke', type: 'besta', attack: 28, defense: 42, height: 0.87
};
describe( "Create new pokemon", () => {
it('expect a new pokemon has created', (done) => {
pokeController.create(poke, (err,data) => {
expect(err).to.not.exist;
expect(data._id).to.exist;
expect(data.attack).to.be.eq(28);
expect(data.defense).to.be.eq(42);
expect(data.height).to.be.eq(0.87);
expect(data.type).to.be.eq('besta');
expect(data.name).to.be.eq('Novo Poke');
done();
});
});
});
describe( "Find pokemons with type eq besta", () => {
it('expect a list of pokemons of type besta', (done) => {
const query = {type: 'besta' };
pokeController.retrive(query, (err,data) => {
expect(err).to.not.exist;
expect(data).to.be.instanceof(Array);
data.forEach((pokemon) => expect(pokemon).to.have.property('type').and.equal('besta'));
done();
});
});
});
const queryUpRm = {name: 'Novo Poke'};
describe("Update the pokemon ", () => {
it('expect update the pokemon', (done) => {
const mod = {attack: 82, defense: 27};
const options = {};
pokeController.update(queryUpRm, mod, options, (err,data) => {
expect(err).to.not.exist;
expect(data.nModified).to.be.eq(1);
expect(data.ok).to.be.eq(1);
done();
});
});
});
describe('delete the pokemon', () => {
it('expect delete the pokemon', (done) => {
pokeController.delete(queryUpRm, (err, data) => {
expect(err).to.not.exist;
expect(data.result.ok).to.be.eq(1);
done();
});
});
});
});
```
`
Resultado após implementação dos testes e antes de implementar o controller.
```
mocha controller-poke-test.js

Resultado após a implmentação dos metodos update e delete no controller.
```

4 passing (89ms)
```
###4) Defina TDD em 3 linhas, baseado no que foi dito ate o momento.
TDD é uma metodologia de desenvolvimento baseada em testes. Ou seja, primeiro você constroi os casos de teste a partir da funcionalidade que deseja no sistema em seguida constrói o código para resolver aquele teste e refatora, com intuito de ter uma aplicação sempre testável e com o mínimo de bugs possíveis.

# Node.js - Aula 09 - Exercício
**user:** [ednilsonamaral](https://github.com/ednilsonamaral)
**autor:** Ednilson Amaral
## Faça uma lista de todas as funções que o módulo `assert` possui e coloque no MD.
* `assert(value[, message])`;
* `assert.deepEqual(actual, expected[, message])`;
* `assert.deepStrictEqual(actual, expected[, message])`;
* `assert.doesNotThrow(block[, error][, message])`;
* `assert.equal(actual, expected[, message])`;
* `assert.fail(actual, expected, message, operator)`;
* `assert.ifError(value)`;
* `assert.notDeepEqual(actual, expected[, message])`;
* `assert.notDeepStrictEqual(actual, expected[, message])`;
* `assert.notEqual(actual, expected[, message])`;
* `assert.notStrictEqual(actual, expected[, message])`;
* `assert.ok(value[, message])`;
* `assert.strictEqual(actual, expected[, message])`;
* `assert.throws(block[, error][, message])`.
## Modifique todos os testes que estão sendo usados no `assert.equal` para `assert.deepStrictEqual(valor, result, 'comentário')`, faça todos passarem, coloque os testes no MD.
Primeiramente, fiz o teste falhar.
`add.spec.js`
```js
'use strict';
const assert = require('assert');
assert.deepStrictEqual(3, 2, ['Os números apresentados não são iguais!']);
```
Saída no terminal:
```
$ mocha add.spec.js
assert.js:89
throw new assert.AssertionError({
^
AssertionError: Os números apresentados não são iguais!
at Object.<anonymous> (/var/www/be-mean-instagram-nodejs/class-09/assert/add.spec.js:5:8)
at Module._compile (module.js:413:34)
at Object.Module._extensions..js (module.js:422:10)
at Module.load (module.js:357:32)
at Function.Module._load (module.js:314:12)
at Module.require (module.js:367:17)
at require (internal/module.js:16:19)
at /usr/lib/node_modules/mocha/lib/mocha.js:219:27
at Array.forEach (native)
at Mocha.loadFiles (/usr/lib/node_modules/mocha/lib/mocha.js:216:14)
at Mocha.run (/usr/lib/node_modules/mocha/lib/mocha.js:468:10)
at Object.<anonymous> (/usr/lib/node_modules/mocha/bin/_mocha:403:18)
at Module._compile (module.js:413:34)
at Object.Module._extensions..js (module.js:422:10)
at Module.load (module.js:357:32)
at Function.Module._load (module.js:314:12)
at Function.Module.runMain (module.js:447:10)
at startup (node.js:141:18)
at node.js:933:3
```
Então, após, fiz o teste passar:
`add.spec.js`
```js
'use strict';
const assert = require('assert');
assert.deepStrictEqual(3, 3, ['Os números apresentados não são iguais!']);
```
Saída no terminal:
```
$ mocha add.spec.js
1 passing (5ms)
```
## Na Calculadora do Chai, crie mais 3 testes, um para divisão, outro para multiplicação e um para raiz quadrada, lembrando que não deve aceitar divisão por zero.
* Use o `expect` para testar a exceção da divisão por zero.
Os arquivos são:
`calc.js`
```js
'use strict';
let sum = (a,b) => a+b;
let sub = (a,b) => a-b;
let mult = (a,b) => a*b;
let div = (a,b) => a === 0 || b === 0 ? 0 : a / b;
let sqtr = a => Math.sqrt(a);
module.exports = {
sum : sum,
sub : sub,
mult : mult,
div : div,
sqtr : sqtr
};
```
`calc.spec.js`
```js
'use strict';
const expect = require('chai').expect;
const calc = require('./calc');
describe('calc', function() {
describe('calc testing', () => {
it('sum of two number', () => {
expect(calc.sum(1,1)).to.equal(2);
});
it('sub of two number', () => {
expect(calc.sub(2,5)).to.equal(-3);
});
it('mult of two number', () => {
expect(calc.mult(5,5)).to.equal(25);
});
it('div of two number', () => {
expect(calc.div(15,5)).to.equal(3);
});
it('div of two number dont aceept div by zero', () => {
expect(calc.div(15,0)).to.equal(0);
expect(calc.div(0,1)).to.equal(0);
});
it('sqtr of a number', () => {
expect(calc.sqtr(16)).to.equal(3);
});
});
});
```
Falhando, temos a saída no terminal:
```
$ mocha calc.spec.js
calc
calc testing
✓ sum of two number
✓ sub of two number
✓ mult of two number
✓ div of two number
✓ div of two number dont aceept div by zero
1) sqtr of a number
5 passing (27ms)
1 failing
1) calc calc testing sqtr of a number:
AssertionError: expected 4 to equal 3
+ expected - actual
-4
+3
at Context.<anonymous> (calc.spec.js:30:29)
```
Passando, temos a saída no terminal:
```
$ mocha calc.spec.js
calc
calc testing
✓ sum of two number
✓ sub of two number
✓ mult of two number
✓ div of two number
✓ div of two number dont aceept div by zero
✓ sqtr of a number
6 passing (20ms)
```
Apenas um pequenina observação, quando fui fazer esse exercício (16/03/2016 às 08:30) fui visualizar os exemplos na apostila, então acabei notando que o Prof. Itacir colocou como exemplo a resolução do exercício, já com os módulos solicitados por ele e raiz quadrada. Apenas fiz os testes e colei os resultados aqui. Porém, os códigos acima são idênticos aos exemplos que ele deixou na apostila. [Link](https://github.com/Webschool-io/be-mean-instagram/tree/master/Apostila/module-nodejs/src/tdd/chai)!
## Use o exemplo de testes do *getter* e *setter* e crie um teste para o *method*, use o exemplo (lembre-se de usar callback é testar):
[https://github.com/Webschool-io/be-mean-instagram/blob/master/Apostila/module-nodejs/src/mongoose-atomic/schema-method.js](https://github.com/Webschool-io/be-mean-instagram/blob/master/Apostila/module-nodejs/src/mongoose-atomic/schema-method.js)
`schema-method.spec.js`
```js
'use strict';
const expect = require('chai').expect,
Pokemon = require('./schema-method'),
util = require('util');
describe('Testando Methods', () => {
const namePokemonzinho = {name: 'Pikachu'};
const typePokemonzinho = {type: 'fogo'};
describe('method... ', () => {
it('expect type.typePokemonzinho to be eq ', () => {
Pokemon.findOne(typePokemonzinho, (err, data) => {
expect(err).to.not.exist;
expect(data.type).to.be.eq(typePokemonzinho);
done();
});
});
});
});
```
Saída no terminal:
```
$ mocha schema-method.spec.js
Testando Methods
method...
✓ expect type.typePokemonzinho to be eq
1 passing (60ms)
```
## Use o exemplo de testes do *getter* e *setter*, o *static*, use o exemplo (lembre-se de usar callback é testar):
[https://github.com/Webschool-io/be-mean-instagram/blob/master/Apostila/module-nodejs/src/mongoose-atomic/schema-static.js](https://github.com/Webschool-io/be-mean-instagram/blob/master/Apostila/module-nodejs/src/mongoose-atomic/schema-static.js)
`schema-static.spec.js`
```js
'use strict';
const expect = require('chai').expect,
Pokemon = require('./schema-method'),
util = require('util');
describe('Testando Static', () => {
const namePokemonzinho = {name: /pikachu/i};
describe('static... ', () => {
it('expect name.namePokemonzinho to be eq ', () => {
Pokemon.findOne(namePokemonzinho, (err, data) => {
expect(err).to.not.exist;
expect(data.name).to.be.eq(namePokemonzinho);
done();
});
});
});
});
```
Saída no terminal:
```
$ mocha schema-static.spec.js
Testando Static
static...
✓ expect name.namePokemonzinho to be eq
1 passing (56ms)
```
## No *controller* ainda faltam dois métodos para testar, o *update* e *delete*, crie-os e faça os testes, no mesmo aRquivo que contém os testes, *create* e *retrieve*.
### Update
```js
'use strict';
const expect = require('chai').expect;
const ctrl = require('./pokemon-controller');
describe('Controller of Pokemons', () => {
describe('UPDATE A POKEMON... ', () => {
const descriptionPokemonzinho = {description: 'olá, tudo bem?!'};
const attackPokemonzinho = {attack: {$gte: 25}};
it('expect update a pokemonzinho ', done => {
ctrl.update(descriptionPokemonzinho, attackPokemonzinho,(err,data) => {
expect(err).to.not.exist;
expect(data._id).to.exist;
expect(data.attack).to.be.eq(attackPokemonzinho);
expect(data.description).to.be.eq(descriptionPokemonzinho);
done();
});
});
});
});
```
Saída no terminal:
```
$ mocha pokemon-controller.spec.js
Controller of Pokemons
UPDATE A POKEMON...
Alterou: { result: { ok: 1, n: 1},
✓ expect update a pokemonzinho
1 passing (56ms)
```
### Delete
```js
'use strict';
const expect = require('chai').expect;
const ctrl = require('./pokemon-controller');
describe('Controller of Pokemons', () => {
describe('DELETE A POKEMON... ', () => {
const descriptionPokemonzinho = {description: 'olá, tudo bem?!'};
const attackPokemonzinho = {attack: {$gte: 25}};
it('expect delete a pokemonzinho ', done => {
ctrl.delete(attackPokemonzinho,(err,data) => {
expect(err).to.not.exist;
expect(data._id).to.exist;
expect(data.attack).to.be.eq(attackPokemonzinho);
done();
});
});
});
});
```
Saída no terminal:
```
$ mocha pokemon-controller.spec.js
Controller of Pokemons
DELETE A POKEMON...
Deletou: { result: { ok: 1, n: 1},
✓ expect delete a pokemonzinho
1 passing (56ms)
```
## Defina TDD em 3 linhas, baseado no que foi dito até o momento.
TDD é o desenvolvimento de softwares orientado a testes. Não fica apenas testando os códigos, também é considerado uma filosofia. Fortemente influenciada pelo movimento ágil. Ele traz inúmeras vantagens para sistemas complexos, sejam pequenos, médios ou grandes, já que é possível reduzir o tempo de *deploy* e correção de bugs, não desenvolvendo códigos desnecessários, melhorando assim a qualidade do software.

## Defina TDD em 3 linhas, baseado no que foi dito até o momento.
TDD é o desenvolvimento de softwares orientado a testes, TDD é o Desenvolvimento Orientado por Testes ou para os mais THUG LIFE'S, TEST DRIVEN DEVELOPMENT, TDD é vida, TDD é amor. TDD te ajuda reduzindo o tempo de deploys e correção de bugs. Basicamente ele se baseia em pequenos ciclos de repetições e nós desenvolvemos o nosso software baseado em testes que são escritos antes do nosso código de produção!
- Clico de Desenvolvimento
+ RED
* Escrevemos esse teste em que inicialmente ele não passa
(Depois disso, adicionamos uma nova funcionalidade do sistema)
+ GREEN
* Fazemos o teste passar nessa etapa
+ REFACTOR
* Refatoramos o código da nova funcionalidade
(E por fim, escrevemos o próximo Teste)
Use TDD e seja feliz :heart:
Fiz um belo Marketing agora.

# Node.js - Aula 10 - Exercício
**user:** [tuchedsf](https://github.com/tuchedsf)
**autor:** Diego Ferreira
##PARTE 01
###1) Criar um módulo de redirecionamento para quando não encontrar a rota redirecionar para url/404.
```js
//modulo
'use strict'
module.exports = (req,res) => {
res.redirect('/404');
}
//Principal
'use strict';
const express = require('express');
const app = express();
const callback404 = require('./modulo.redirect');
app.get('/', (req,res) => {
res.send('<h1> Hello World </h1>');
}).get('/404', (req,res) => {
res.status(404).send('404 - Not Found');
}).get('/*', (req,res) => {
callback404(req,res);
});
app.listen(3000, () =>{
console.log('Servidor sendo executado');
});
```
### 2) Criar módulo onde seja passado o retorno, podendo ser string ou buffer, caso seja String definir cabeçalho correto mesmo usando res.send.
```js
//modulo
module.exports = (req,res) => {
res.set('Content-Type', 'text-html'); //seta o content type para text-html, senao iria mostrar 8ctrestrem
res.send(new Buffer('<h1> Hello World </h1>'));
}
//Principal
'use strict';
const express = require('express');
const app = express();
const Content = require('./modules/Content');
app.get('/', (req,res) => {
return Content(req,res);
});
app.listen(3000, () =>{
console.log('Servidor sendo executado');
});
```
Cabeçalho:
```
Connection →keep-alive
Content-Length →22
Content-Type →text-html
Date →Sat, 28 May 2016 16:24:07 GMT
ETag →W/"16-JxTuzBN3iv2w2JCcxw774w"
X-Powered-By →Express
```
## PARTE 2
### 3) Criar um módulo para renderização de views, onde o mesmo recebe o caminho para a view e o tipo do template engine, para retornar a view corretamente.
No meu exemplo são utilizados os templates pug e jade, ou seja, o modulo recebe dois parametros o primeiro template que pode ser pug ou jade e o segundo a view que o mesmo deseja exibir.
app-exercicio3.js
```js
'use strict';
const express = require('express');
const app = express();
const path = require('path');
const users = [
{name : "Diego"}
,{name: "Jose "}
];
app.get('/users/:template/:view', function (req, res, next) {
const template = req.params.template;
const view = req.params.view;
console.log(template);
app.set('view engine',template);
switch(view) {
case 'list':
res.render(path.join(__dirname,'/modules/users/views/'+view), {title: 'list user', message: 'Lista Usuarios', template: template, view: view,users: users});
break;
case 'index':
res.render(path.join(__dirname,'/modules/users/views/'+view), {title: 'Index file', message: 'Seja bem vindo pagina inicial', template: template, view: view});
default:
res.send(404, 'Não achei!');
}
});
app.listen(3000, function () {
console.log('Servidor rodando em locahost:3000');
});
```
Obs.: Por padrão o pug e o jade utilizam da mesma formatação então apenas exibi o código de montagem da tela uma unica vez.
views/index.jade === views/index.pug
```
html
head
title= title
body
h1= template + ' - ' + view
br
h2= message
```
views/list.jade === views/list.pug
```
html
head
title= title
body
h1= template + ' - ' + view
br
h2= message
ul
each user in users
li= user.name
```
Chamadas
```
http://localhost:3000/users/jade/index
http://localhost:3000/users/pug/index
jade - index
Seja bem vindo pagina inicial
http://localhost:3000/users/jade/list
http://localhost:3000/users/pug/list
jade - list
Lista Usuarios
Diego
Jose
```
### 4) Criar um módulo para entrega de arquivos, onde o mesmo recebe o caminho para o arquivo e o tipo do arquivo, para retornar o arquivo corretamente.
module/SendFiles.js
```js
'use strict';
module.exports = (req, res) => {
const options = {
root: __dirname + '/public/',
dotfiles: 'deny',
headers: {
'x-timestamp': Date.now(),
'x-sent': true
}
};
let fileName = req.params.name;
const fileType = req.params.type;
switch (fileType) {
case 'png':
res.set('Content-Type', 'image/png');
fileName = fileName +'.'+fileType;
break;
default:
res.status(400).send('tipo do arquivo solicitado invalido');
break;
}
res.sendFile(fileName, options, function (err) {
if (err) {
console.log(err);
res.status(err.status).end();
}
else {
console.log('Sent:', fileName);

# Node.js - Aula 10 - Exercício
**User:** [gkal19](https://github.com/gkal19)
**Autor:** Gabriel Kalani
### 1 - Criar um módulo de redirecionamento para quando não encontrar a rota redirecionar para `url/404`
```js
'use strict';
const express = require('express');
const app = express();
app.get('/', (req, res) => {
res.redirect('admin');
})
.get('/admin', (req, res) => {
res.send('Rota de Admin');
});
/*app.use(function(req, res, next) {
res.status(404).send('Nada encontrado!');
});*/
app.get('*', (req, res) => {
res.send('<section align="center"><h1>O que houve?! Tivemos um 404 aqui.</h1><hr><img src="https://raw.githubusercontent.com/Webschool-io/be-mean-instagram/master/Apostila/module-nodejs/src/aula-express/public/logo-webschool.png"></section>', 404);
});
app.listen(3000, () => {
console.log('Servidor rodando em localhost:3000');
});
```
##### Resultado
> Explicando, bom no código podem ver que o GET está setado para ir apenas para `/admin` e nenhum outro além dele. Por isso na imagem acima, eu acessei no browser: `http://localhost:3000/admin/p` que resultou no seguinte.
### 2 - Adicionar o retorno correto para os seguinte códigos:
> 200,201,202,405,500
```js
// 200
app.get('/', (req, res) => {
res.status(200).send('AEE CARAI, DE BOA!')
});
// 201
app.get('/', (req, res) => {
res.status(201).send('DE BOA!')
});
// 202
app.get('/', (req, res) => {
res.status(202).send('EHH, PODE SER!')
});
// 405
app.get('/', (req, res) => {
res.status(405).send('NÃO PERMITIDO!')
});
// 500
app.get('/', (req, res) => {
res.status(500).send('ERRO NO SERVIDOR!')
});
```
### 3 - Criar um módulo onde seja passado o retorno, podendo ser String ou Buffer, caso seja String definir cabeçalho correto mesmo usando res.send
### 4 - Criar uma busca, dos Pokemons, com o Mongoose que pagine o resultado retornando os links corretamente e que essa busca seja retornada como:
- html
- json
ps: Não esquecer do link para previous e first quando necessários.

## Motivation and Action
Maybe someday, your favorite AI company will force you to make your stable diffusion models private. It's time to copy and paste them to other cloud providers to ensure they can't be taken down. This repo will begin with 105 models from the [stable-diffusion-webui-colab](https://github.com/camenduru/stable-diffusion-webui-colab) project and will provide a simple JSON file for the data inside. It will continue to grow.
## What is the AI Creator Archive
An AI Creator Archive is a repository of information about the individuals and teams who create and develop artificial intelligence models.
The archive can include information such as the creators' notable contributions to the field of AI.
It also include information about the AI models they have developed.
The purpose of an AI Creator Archive is to provide transparency and recognition for the creators of AI models.
It is also useful for people who are interested in learning about the history and development of AI and the people behind it.
## Contributing to the AI Creator Archive
Just open an issue with your `username`, `model name`, `model version`, `model token(s)`, `model direct link` or `Google Drive link`, `4 images with PNG info`, and if you want, an `info.txt`
## Image Formats
Images should not contain any nudity. Remember how GitHub deleted the web UI without warning.
## Automation Design
All files and the Colab notebook will be created with the server, the Colab will be published on this link: https://github.com/camenduru/stable-diffusion-webui-colab
