Architecture

Labrinth

Labrinth is the backend API service for Modrinth.

Testing

Before a pull request can be opened, run cargo clippy -p labrinth --all-targets and make sure there are ZERO warnings, otherwise CI will fail.

Use cargo test -p labrinth --all-targets to test your changes. All tests must pass, otherwise CI will fail.

To prepare the sqlx cache, cd into apps/labrinth and run cargo sqlx prepare. Make sure to NEVER run cargo sqlx prepare --workspace.

Read the root docker-compose.yml to see what running services are available while developing. Use docker exec to access these services.

When the user refers to "performing pre-PR checks", do the following:

  • Run clippy as described above
  • DO NOT run tests unless explicitly requested (they take a long time)
  • Prepare the sqlx cache

Clickhouse

Use docker exec labrinth-clickhouse clickhouse-client to access the Clickhouse instance. We use the staging_ariadne database to store data in testing.

Postgres

Use docker exec labrinth-postgres psql -U postgres to access the PostgreSQL instance.
