lint-staged

lint-staged is a tool that runs linters and formatters against staged git files, preventing subpar code from entering the repository. It only processes files that are staged for commit, making it faster and more relevant than running the same tools on the entire codebase. The current stable version is 16.4.0, released in early 2025. It is actively maintained with frequent patch releases. Key differentiators include support for git stash backup, rollback on failure, flexible configuration using multiple file formats, and integration with popular tools like ESLint, Prettier, and Stylelint. It replaces micromatch with picomatch in v16.4.0 for reduced dependencies. Requires Node.js >=20.17.
