ESLint plugin including configurations and custom rules for WordPress development.
Install the module
npm install @wordpress/eslint-plugin --save-devTo opt-in to the default configuration, extend your own project's .eslintrc file:
{
"extends": [ "plugin:@wordpress/eslint-plugin/recommended" ]
}Refer to the ESLint documentation on Shareable Configs for more information.
The recommended preset will include rules governing an ES2015+ environment, and includes rules from the eslint-plugin-jsx-a11y and eslint-plugin-react projects.
Alternatively, you can opt-in to only the more granular rulesets offered by the plugin. These include:
es5esnextjsx-a11yreact
For example, if your project does not use React, you could consider extending including only the ESNext rules in your project using the following extends definition:
{
"extends": [ "plugin:@wordpress/eslint-plugin/esnext" ]
}These rules can be used additively, so you could extend both esnext and custom rulesets, but omit the react and jsx-a11y configurations.
The granular rulesets will not define any environment globals. As such, if they are required for your project, you will need to define them yourself.
| Rule | Description |
|---|---|
| dependency-group | Enforce dependencies docblocks formatting |
| gutenberg-phase | Governs the use of the process.env.GUTENBERG_PHASE constant |
| no-unused-vars-before-return | Disallow assigning variable values if unused before a return |
| valid-sprintf | Disallow assigning variable values if unused before a return |
If you are using WordPress' .jshintrc JSHint configuration and you would like to take the first step to migrate to an ESLint equivalent it is also possible to define your own project's .eslintrc file as:
{
"extends": [ "plugin:@wordpress/eslint-plugin/jshint" ]
}
