eslint-import-resolver-typescript

This plugin adds TypeScript support to eslint-plugin-import.

This means you can:

• import/require files with extension .cts/.mts/.ts/.tsx!
• Use paths defined in tsconfig.json.
• Prefer resolve @types/* definitions over plain .js.
• Multiple tsconfigs support just like normal.
• exports fields support in package.json

Notice

After version 2.0.0, .d.ts will take higher priority then normal .js files on resolving node_modules packages in favor of @types/* definitions.

If you're facing some problems on rules import/default or import/named from eslint-plugin-import, do not post any issue here, because they are just working exactly as expected on our sides, take import-js/eslint-plugin-import#1525 as reference or post a new issue to eslint-plugin-import instead.

Installation

# npm
npm i -D eslint-plugin-import eslint-import-resolver-typescript

# pnpm
pnpm i -D eslint-plugin-import eslint-import-resolver-typescript

Configuration

Add the following to your .eslintrc config:

{
  "plugins": ["import"],
  "rules": {
    // turn on errors for missing imports
    "import/no-unresolved": "error"
  },
  "settings": {
    "import/parsers": {
      "@typescript-eslint/parser": [".ts", ".tsx"]
    },
    "import/resolver": {
      "typescript": {
        "alwaysTryTypes": true, // always try to resolve types under `<root>@types` directory even it doesn't contain any source code, like `@types/unist`

        // Choose from one of the "project" configs below or omit to use <root>/tsconfig.json by default

        // use <root>/path/to/folder/tsconfig.json
        "project": "path/to/folder",

        // Multiple tsconfigs (Useful for monorepos)

        // use a glob pattern
        "project": "packages/*/tsconfig.json",

        // use an array
        "project": [
          "packages/module-a/tsconfig.json",
          "packages/module-b/tsconfig.json"
        ],

        // use an array of glob patterns
        "project": [
          "packages/*/tsconfig.json",
          "other-packages/*/tsconfig.json"
        ]
      }
    }
  }
}
