# Development with devcontainer
This project includes a devcontainer configuration that allows you to open the project in a container with a fully configured development environment.
Both frontend and backend environments are initialized when the container is started.

You can learn more in the [Dev Containers documentation](https://code.visualstudio.com/docs/devcontainers/containers).
## Pros of Devcontainer
Unified Development Environment: By using devcontainers, you can ensure that all developers are developing in the same environment, reducing the occurrence of "it works on my machine" type of issues.
Quick Start: New developers can set up their development environment in a few simple steps, without spending a lot of time on environment configuration.
Isolation: Devcontainers isolate your project from your host operating system, reducing the chance of OS updates or other application installations impacting the development environment.
## Cons of Devcontainer
Learning Curve: For developers unfamiliar with Docker and VS Code, using devcontainers may be somewhat complex.
Performance Impact: While usually minimal, programs running inside a devcontainer may be slightly slower than those running directly on the host.
## Troubleshooting
if you see such error message when you open this project in codespaces:
a simple workaround is change `/signin` endpoint into another one, then login with GitHub account and close the tab, then change it back to `/signin` endpoint. Then all things will be fine.
The reason is `signin` endpoint is not allowed in codespaces, details can be found [here](https://github.com/orgs/community/discussions/5204) |
