Code quality

We have several tools configured for checking code quality:

• Pre-commit checks run automatically at commit time. Install checks with pre-commit install. Run them manually with pre-commit run --all-files. Will exit non-zero when finding errors or changing files.

  • Ruff formats and lints (sometimes autofixes) Python code.

  • Generic pre-commit checks help avoid common mistakes like committing large files or trailing whitespace.

• Package scripts (defined in package.json) to check (and/or fix) TypeScript, JavaScript, CSS, JSON, Markdown, and YAML. Run manually with jlpm run lint. Will exit 0 when applying fixes. Check the logs and/or ``git status`` after every run.

  • Prettier formats the file types listed above.

  • Eslint lints (sometimes autofixes) JS/TS code.
