Lint-staged is a command-line utility designed to automate code quality checks and formatting tasks within a Git repository. It functions as a pre-commit hook runner that executes defined operations exclusively on files currently staged for commit, ensuring that only code meeting project standards is permanently saved.
The tool distinguishes itself by providing granular control over the development workflow through file filtering and task orchestration. It uses glob-pattern matching to isolate specific file types and executes sequences of shell commands in a strict order. To maintain repository integrity, it manages task concurrency and preserves the working directory state, automatically rolling back changes if any step in the execution sequence fails.
This utility supports a range of repository automation tasks, including automated code formatting and validation, by integrating directly into the commit process. It is configured through standard project files and is intended for use as part of a local development environment.
