eslint-plugin-type-imports

An ESLint plugin to enforce consistent usage of TypeScript type imports.

Installation

npm install --save-dev eslint-plugin-type-imports

Configuration

Add the plugin to your ESLint config (eslint.config.js):

import typeImports from 'eslint-plugin-type-imports'

export default [
  // ... other configs
  typeImports.configs.recommended,
]

Rules

enforce-consistent-type-keyword-in-imports

Enforces that type imports use the type keyword outside of curly braces rather than inline on each specifier.

Bad:

import { type User } from './types'
import { type User, type Post } from './types'

Good:

import type { User } from './types'
import type { User, Post } from './types'

prevent-duplicate-imports

Prevents multiple import statements from the same package or path. The auto-fix merges them into a single import.

Bad:

import { a } from './utils'
import { b } from './utils'

Good:

import { a, b } from './utils'

Type imports are handled correctly:

// Two type-only imports are merged with the type keyword preserved
import type { A } from './types'
import type { B } from './types'
// → import type { A, B } from './types'

// Mixed value and type imports are merged with inline type specifiers
import { a } from './utils'
import type { B } from './utils'
// → import { a, type B } from './utils'

Default imports are merged with named imports:

import def from './module'
import { a } from './module'
// → import def, { a } from './module'

Note: Namespace imports (import * as ns) and side-effect imports (import './module') are excluded from this rule and left as-is.
