Latest commit 705d88f May 23, 2017 @not-an-aardvark not-an-aardvark committed with platinumazure Docs: Update CLA link on Pull Requests page (#8642)
This is the same as eslint/, but it's retargeted to the eslint repo so that it doesn't get overwritten the next time the site is generated.

Developer Guide

This guide is intended for those who wish to:

  • Contribute code to ESLint
  • Create their own rules for ESLint

In order to work with ESLint as a developer, it's recommended that:

  • You know JavaScript, since ESLint is written in JavaScript.
  • You have some familiarity with Node.js, since ESLint runs on it.
  • You're comfortable with command-line programs.
  • You understand unit tests and why they're important.

If that sounds like you, then continue reading to get started.

Section 1: Get the Source Code

Before you can get started, you'll need to get a copy of the ESLint source code. This section explains how to do that and a little about the source code structure.

Section 2: Set up a Development Environment

Developing for ESLint is a bit different than running it on the command line. This section shows you how to set up a development environment and get you ready to write code.

Section 3: Run the Unit Tests

There are a lot of unit tests included with ESLint to make sure that we're keeping on top of code quality. This section explains how to run the unit tests.

Section 4: Working with Rules

You're finally ready to start working with rules. You may want to fix an existing rule or create a new one. This section explains how to do all of that.

Section 5: Working with Plugins

You've developed library-specific rules for ESLint and you want to share it with the community. You can publish an ESLint plugin on npm.

Section 6: Node.js API

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.

Section 7: Contributing

Once you've made changes that you want to share with the community, the next step is to submit those changes back via a pull request.
