Chick 🐤

A real-time, synchronous junior.guru Discord bot.

Features

All junior.guru automation happens asynchronously (with up-to-24h delay) in the main monolith codebase, except of the following tasks provided by this bot:

[x] Creating threads in #past-vedle-pasti
[x] Creating threads in #můj-dnešní-objev
[x] Reacting to member-made threads in #práce-inzeráty
[x] Reacting to member-made threads in #práce-hledám
[x] Creating threads in #ahoj
[x] Greeting new members in #ahoj
[x] Providing reviews in #cv-github-linkedin
[ ] Saving pins to members' DMs #13

Please, update the above list if adding features.

Design decisions

The original, asynchronous bot installs and uses this codebase to run the same code and perform the same tasks, idempotently:

If this bot crashes, the asynchronous bot will do the same stuff, just with a delay.
The purpose of this bot is to provide non-critical progressive enhancement, which can be dropped at any moment.
To keep the architecture simple, this bot should have no state. There should be no database. It should only react to the state and events of the Discord server, and write to the Discord server.
The asynchronous bot should monitor whether this bot is up and running. If it's not, it should fail the build, but non-critically (similar to checking broken links in HTML).

Installation

You'll need poetry installed.
Clone this repository: git clone git@github.com:juniorguru/chick.git
Go to the project directory: cd chick
Install the project: poetry install

Development

Running locally:

Set the DISCORD_API_KEY environment variable to your Discord bot token. Set the GITHUB_API_KEY environment variable to your GitHub API token. Using direnv might help setting environment variables automatically in your shell when you navigate to the project directory.
Run poetry run chick to start the bot.
Press Ctrl+C to stop the bot.

Useful commands:

Run poetry run chick --prod to temporarily replace the production instance with the local one if you need to test something.
To test, run pytest.
To format code, run ruff format.
To organize imports and fix other issues, run ruff check --fix.

Deployment

The bot is deployed to fly.io. Everything related to deployment is in the Dockerfile. There's also fly.toml, but that's something the flyctl has generated and only they know what it is good for.

There is no need to deploy this bot manually. Everything merged to the main branch of the GitHub repo gets automatically deployed to Fly.

For this to work, the output of flyctl auth token must be set as FLY_API_TOKEN secret in the GitHub repo settings. The rest of the setup is in .github/workflows/build.yml.

If you insist to deploy manually from your local machine, follow these steps:

Have a hobby account at fly.io.
Have a flyctl installed and be logged in.
Set the environment variable using flyctl secrets set DISCORD_API_KEY=...
Run flyctl launch in the project directory.
Run flyctl deploy if not deployed already.
