builtin-modules

What is builtin-modules?

The builtin-modules package provides a list of the modules that come pre-packaged with Node.js. These are modules that you can require in your code without needing to install them separately, as they are built into the Node.js runtime. This package is useful for developers who want to ensure they are using only core modules or need to check if a module name corresponds to a built-in module.

What are builtin-modules's main functionalities?

List of all builtin modules

This feature allows you to retrieve an array of all the builtin module names in Node.js. The code sample shows how to require the package and log the list of module names to the console.

const builtinModules = require('builtin-modules');
console.log(builtinModules);

List of builtin modules as of a specific Node.js version

This feature provides a list of builtin modules for a specific version of Node.js. The 'static' import gives you a list that corresponds to a particular Node.js release, which is useful when working with environments that may not be up-to-date with the latest Node.js version.

const builtinModules = require('builtin-modules/static');
console.log(builtinModules);

Other packages similar to builtin-modules

is-core-module

The 'is-core-module' package is similar to 'builtin-modules' in that it allows you to check if a given module name is a Node.js core module. However, instead of providing a list of modules, it offers a function that returns a boolean indicating whether the module is built-in or not. This can be more convenient for certain use cases where you need to check modules on a case-by-case basis.

resolve

While 'resolve' is not exclusively focused on built-in modules, it is a package that can resolve the path of a module, including core Node.js modules. It can be used to find the absolute path of a module, which includes checking if a module is a built-in module. This package offers more general module resolution capabilities compared to 'builtin-modules', which is specifically tailored to list Node.js built-in modules.

README

builtin-modules

A static list of the Node.js builtin modules from the latest Node.js version

The list is just a JSON file and can be used anywhere.

Install

npm install builtin-modules

Usage

import builtinModules from 'builtin-modules';

console.log(builtinModules);
//=> ['assert', 'buffer', …]

Tip

To get a list from the current Node.js version, use the built-in API:

import {builtinModules} from 'node:module';
