+# import/prefer-node-builtin-imports
+
+🔧 This rule is automatically fixable by the [`--fix` CLI option](https://eslint.org/docs/latest/user-guide/command-line-interface#--fix).
+
+<!-- end auto-generated rule header -->
+
+Reports when there is no `node:` protocol for builtin modules.
+
+```ts
+import path from "node:path";
+```
+
+## Rule Details
+
+This rule enforces that builtins node imports are using `node:` protocol. It resolved the conflict of a module (npm-installed) in `node_modules` overriding the built-in module. Besides that, it is also clear that a built-in Node.js module is imported.
+
+## Examples
+
+❌ Invalid
+
+```ts
+import fs from "fs";
+export { promises } from "fs";
+// require
+const fs = require("fs/promises");
+```
+
+✅ Valid
+
+```ts
+import fs from "node:fs";
+export { promises } from "node:fs";
+// require
+const fs = require("node:fs/promises");
+```
+
+## When Not To Use It
+
+If you are using browser or Bun or Deno since this rule doesn't do anything with them.
