import/group-exports

Reports when named exports are not grouped together in a single export declaration or when multiple assignments to CommonJS module.exports or exports object are present in a single file.

Rationale: An export declaration or module.exports assignment can appear anywhere in the code. By requiring a single export declaration all your exports will remain at one place, making it easier to see what exports a module provides.

Rule Details

This rule warns whenever a single file contains multiple named export declarations or multiple assignments to module.exports (or exports).

Valid

// A single named export declaration -> ok
export const valid = true

const first = true
const second = true

// A single named export declaration -> ok
export {
  first,
  second,
}

// Aggregating exports -> ok
export { default as module1 } from 'module-1'
export { default as module2 } from 'module-2'

// A single exports assignment -> ok
module.exports = {
  first: true,
  second: true
}

const first = true
const second = true

// A single exports assignment -> ok
module.exports = {
  first,
  second,
}

function test() {}
test.property = true
test.another = true

// A single exports assignment -> ok
module.exports = test

const first = true;
type firstType = boolean

// A single named export declaration (type exports handled separately) -> ok
export {first}
export type {firstType}

Invalid

// Multiple named export statements -> not ok!
export const first = true
export const second = true

// Aggregating exports from the same module -> not ok!
export { module1 } from 'module-1'
export { module2 } from 'module-1'

// Multiple exports assignments -> not ok!
exports.first = true
exports.second = true

// Multiple exports assignments -> not ok!
module.exports = {}
module.exports.first = true

// Multiple exports assignments -> not ok!
module.exports = () => {}
module.exports.first = true
module.exports.second = true

type firstType = boolean
type secondType = any

// Multiple named type export statements -> not ok!
export type {firstType}
export type {secondType}

When Not To Use It

If you do not mind having your exports spread across the file, you can safely turn this rule off.
