Working with Lila
What is lila?
Lichess is primarily written in the Scala programming language. The name for the main Lichess codebase is "lila", which stands for "Lichess in Scala".
Navigating the code
The main Lichess code repositories have automatically been added to your workspace. You can find them at:
ls /workspace/lila-docker/repos
To open them in your workspace:
open -r repos/lila # open main lila repository
open -r repos/lila-ws # open websocket repository
Recompiling lila
When you edit a scala file, you'll have to restart lila. In a terminal, type:
./lila-docker lila restart
Recompiling frontend assets
If you're working on TypeScript or SCSS files, you can automatically detect the changes and recompile the assets. In a terminal, type:
./lila-docker ui
Updating Routes
If you edit the conf/routes
file, you'll need to update the route cache.
docker compose exec lila bash -c "./lila playRoutes"
