+# eslint-pullrequest
+
+Run ESLint only on files affected by a PR
+
+[ ![npm version](https://img.shields.io/npm/v/eslint-pullrequest.svg?style=flat) ](https://npmjs.org/package/eslint-pullrequest "View this project on npm") [ ![Issues](https://img.shields.io/github/issues/Sleavely/eslint-pullrequest.svg) ](https://github.com/Sleavely/eslint-pullrequest/issues)
+
+## Usage
+
+In your Bitbucket Pipeline or Github Action, instead of `npx eslint .`:
+```
+npx eslint-pullrequest
+```
+
+It will use your existing ESLint configuration, but will attempt to lint all files in the pull request that have the extensions defined in the `LINTABLE_EXTENSIONS` environment variable. The default value is `.js,.ts,.jsx,.tsx`.
