eslint-import-resolver-typescript-bun

This plugin simply adds workarounds to eslint-import-resolver-typescript when resolving Bun's modules.

You can use eslint-plugin-import on your Bun project directly with this resolver!

How it works

This resolver reads bun-types and list all Bun modules defined there. Currently, we assume all Bun modules start with bun e.g. bun, bun:test, etc.

Then, when resolving, if the requested module is one of the Bun modules detected above, the resolver returns { found: true, path: null }. Otherwise, it delegates to eslint-import-resolver-typescript.

Installation

1# npm
2npm i -D eslint-plugin-import eslint-import-resolver-typescript-bun

Configuration

All configurations are passed to eslint-import-resolver-typescript. Simply replace your resolver name from typescript to typescript-bun!

1module.exports = {
2  extends: ["plugin:import/recommended", "plugin:import/typescript"],
3  parser: "@typescript-eslint/parser",
4  parserOptions: {
5    project: true,
6  },
7  plugins: ["@typescript-eslint"],
8  root: true,
9  settings: {
10    "import/parsers": {
11      "@typescript-eslint/parser": [".ts", ".tsx"],
12    },
13    "import/resolver": {
14      "typescript-bun": {
15        // ^^ HERE! ^^
16        project: true,
17        alwaysTryTypes: true,
18      },
19    },
20  },
21  rules: {
22    "import/order": [
23      "warn",
24      {
