Linting & Formatting
Catch bugs and style issues automatically — before review, before CI, ideally before saving.
Tools by Language

Python — ruff
Replaces flake8, isort, and black in one tool. Extremely fast.
ruff check . # lint
ruff check --fix . # lint + auto-fix
ruff format . # format (replaces black)
Configure in pyproject.toml:
[tool.ruff]
line-length = 100
target-version = "py312"
[tool.ruff.lint]
select = ["E", "F", "I", "UP"]
JavaScript — biome
Single tool for lint + format, no config needed to start.
biome check . # lint + format check
biome check --write . # auto-fix
Go
gofmt is part of the toolchain — just run it.
gofmt -w .
golangci-lint run # broader lint suite
Tips
- Run on save in your editor (not just in CI)
- Auto-fix on commit via a pre-commit hook or
invoke lint --fix - Format is non-negotiable; lint violations should be treated as errors in CI
