import/enforce-node-protocol-usage

🔧 This rule is automatically fixable by the --fix CLI option.

Enforce either using, or omitting, the node: protocol when importing Node.js builtin modules.

Rule Details

This rule enforces that builtins node imports are using, or omitting, the node: protocol.

Determining whether a specifier is a core module depends on the node version being used to run eslint. This version can be specified in the configuration with the import/node-version setting.

Reasons to prefer using the protocol include:

• the code is more explicitly and clearly referencing a Node.js built-in module

Reasons to prefer omitting the protocol include:

• some tools don't support the node: protocol
• the code is more portable, because import maps and automatic polyfilling can be used

Options

The rule requires a single string option which may be one of:

• 'always' - enforces that builtins node imports are using the node: protocol.
• 'never' - enforces that builtins node imports are not using the node: protocol.

Examples

'always'

❌ Invalid

import fs from 'fs';
export { promises } from 'fs';
// require
const fs = require('fs/promises');

✅ Valid

import fs from 'node:fs';
export { promises } from 'node:fs';
import * as test from 'node:test';
// require
const fs = require('node:fs/promises');

'never'

❌ Invalid

import fs from 'node:fs';
export { promises } from 'node:fs';
// require
const fs = require('node:fs/promises');

✅ Valid

import fs from 'fs';
export { promises } from 'fs';

// require
const fs = require('fs/promises');

// This rule will not enforce not using `node:` protocol when the module is only available under the `node:` protocol.
import * as test from 'node:test';

When Not To Use It

If you don't want to consistently enforce using, or omitting, the node: protocol when importing Node.js builtin modules.
