nodeProtocols

Prefer the node: protocol prefix for Node.js built-in modules for clarity and consistency.

✅ This rule is included in the node logical presets.

The node: protocol makes it explicit that the module is a Node.js built-in, preventing confusion with npm packages that might have the same name. The protocol is supported in Node.js 16+ and is the recommended way to import built-ins.

When Not To Use It

Section titled “When Not To Use It”

If you need to support Node.js versions older than 16, you should not use this rule, as the node: protocol was introduced in Node.js 16.0.0.

If you strongly prefer more succinct imports and aren’t worried about confusing userland modules with built-in Node.js modules, this rule might not be for you.
