import/no-unused-modules

Reports:

• modules without any exports
• individual exports not being statically imported or requireed from other modules in the same project

Note: dynamic imports are currently not supported.

Rule Details

Usage

In order for this plugin to work, one of the options missingExports or unusedExports must be enabled (see "Options" section below). In the future, these options will be enabled by default (see https://github.com/benmosher/eslint-plugin-import/issues/1324)

Example:

"rules: {
  ...otherRules,
  "import/no-unused-modules": [1, {"unusedExports": true}]
}

Options

This rule takes the following option:

• missingExports: if true, files without any exports are reported (defaults to false)
• unusedExports: if true, exports without any static usage within other modules are reported (defaults to false)
• src: an array with files/paths to be analyzed. It only applies to unused exports. Defaults to process.cwd(), if not provided
• ignoreExports: an array with files/paths for which unused exports will not be reported (e.g module entry points in a published package)

Example for missing exports

The following will be reported

const class MyClass { /*...*/ } 

function makeClass() { return new MyClass(...arguments) }

The following will not be reported

export default function () { /*...*/ } 

export const foo = function () { /*...*/ } 

export { foo, bar }

export { foo as bar }

Example for unused exports

given file-f:

import { e } from 'file-a'
import { f } from 'file-b'
import * as fileC from  'file-c'
export { default, i0 } from 'file-d' // both will be reported

export const j = 99 // will be reported 

and file-d:

export const i0 = 9 // will not be reported
export const i1 = 9 // will be reported
export default () => {} // will not be reported

and file-c:

export const h = 8 // will not be reported
export default () => {} // will be reported, as export * only considers named exports and ignores default exports

and file-b:

import two, { b, c, doAnything } from 'file-a'

export const f = 6 // will not be reported

and file-a:

const b = 2
const c = 3
const d = 4

export const a = 1 // will be reported

export { b, c } // will not be reported

export { d as e } // will not be reported

export function doAnything() {
  // some code
}  // will not be reported

export default 5 // will not be reported

Important Note

Exports from files listed as a main file (main, browser, or bin fields in package.json) will be ignored by default. This only applies if the package.json is not set to private: true

When not to use

If you don't mind having unused files or dead code within your codebase, you can disable this rule
