This guide is intended for those who wish to extend the functionality of ESLint.
In order to extend ESLint, it’s recommended that:
- You have some familiarity with Node.js, since ESLint runs on it.
- You’re comfortable with command-line programs.
If that sounds like you, then continue reading to get started.
You’ve developed custom rules for ESLint and you want to share them with the community. You can publish an ESLint plugin on npm.
This section explains how to create and modify rules to use with ESLint.
This section explains how you can create a custom formatter to control what ESLint outputs.
If you don’t want to use the default parser of ESLint, this section explains how to create custom parsers.
If you’re interested in writing a tool that uses ESLint, then you can use the Node.js API to get programmatic access to functionality.
