Rumba is MDN's new back-end. It supersedes kuma and mainly powers MDN Plus.

Before you can start working with Rumba, you need to:

1. Install git and Rust.
2. Install additional dependencies:
   • Mac OS brew install libpq && brew link --force libpq
   • Ubuntu: apt install gcc libpq-dev libssl-dev pkg-config
3. Run a PostgreSQL instance:
   • Mac OS: e.g. Postgres.app
   • Docker: docker run --name postgres -p 5432:5432 -e POSTGRES_USER=rumba -e POSTGRES_PASSWORD=rumba -e POSTGRES_DB=mdn -d postgres).
4. Run an Elastic instance:
   • Docker: docker run --name elastic -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -d elasticsearch:8.3.3
5. Copy .settings.dev.toml to .settings.toml.
6. Run cargo run.
7. To create an authenticated session navigate to http://localhost:8000/users/fxa/login/authenticate/?next=%2F and login with your firefox staging account
8. To check you are logged in and ready to go navigate to http://localhost:8000/api/v1/whoami you should see your logged in user information.

All changes to Rumba are required to be formatted with Rustfmt (cargo fmt --all) and free of Clippy linting errors or warnings (cargo clippy --all --all-features -- -D warnings).

To avoid committing unformatted or unlinted changes, we recommend setting up a pre-commit Git hook in your local repository checkout:

touch .git/hooks/pre-commit
chmod +x .git/hooks/pre-commit
cat <<EOF >> .git/hooks/pre-commit
#!/usr/bin/env bash

echo "Running cargo fmt..."
cargo fmt --all -- --check

echo "Running cargo clippy..."
cargo clippy --all --all-features -- -D warnings
EOF
