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


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: Working with Custom Parsers

If you aren’t going to use the default parser of ESLint, this section explains about using custom parsers.


Section 7: 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.

如果你很感兴趣使用ESLint写一个工具,你可以使用 Node.js API。

Section 8: 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.

一旦你做出了与社区共享的更改,下一步就是通过发送 pull 请求提交这些更改。
