eslint-plugin-unused-imports
Find and remove unused es6 module imports. It works by splitting up the no-unused-vars
rule depending on it being an import statement in the AST and providing an autofix rule to remove the nodes if they are imports. This plugin composes the rule no-unused-vars
of either the typescript or js plugin so be aware that the other plugins needs to be installed and reporting correctly for this to do so.
Versions
- Version 4.1.x is for eslint 9 with @typescript-eslint/eslint-plugin v8 to v5
- Version 3.x.x is for eslint 8 with @typescript-eslint/eslint-plugin 6 - 7
- Version 2.x.x is for eslint 8 with @typescript-eslint/eslint-plugin 5
- Version 1.x.x is for eslint 6 and 7.
Typescript
If running typescript with @typescript-eslint make sure to use both @typescript-eslint/eslint-plugin
and @typescript-eslint/parser
.
React
If writing react code you need to install eslint-plugin-react
and enable the two rules react/jsx-uses-react
and react/jsx-uses-vars
. Otherwise all imports for components will be reported unused.
Installation
You'll first need to install ESLint (and @typescript-eslint if using typescript):
npm i eslint --save-dev
Next, install eslint-plugin-unused-imports
:
npm install eslint-plugin-unused-imports --save-dev
Note: If you installed ESLint globally (using the -g
flag) then you must also install eslint-plugin-unused-imports
globally.
Usage
Add unused-imports
to the plugins section of your eslint.config.js
configuration file.
import unusedImports from "eslint-plugin-unused-imports";
export default [{
plugins: {
"unused-imports": unusedImports,
},
rules: {
"no-unused-vars": "off", // or "@typescript-eslint/no-unused-vars": "off",
"unused-imports/no-unused-imports": "error",
"unused-imports/no-unused-vars": [
"warn",
{
"vars": "all",
"varsIgnorePattern": "^_",
"args": "after-used",
"argsIgnorePattern": "^_",
},
]
}
}];
