List of the Node.js builtin modules

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

Install

$ npm install builtin-modules

Usage

const builtinModules = require('builtin-modules');

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

API

Returns an array of builtin modules fetched from the running Node.js version.

Static list

This module also comes bundled with a static array of builtin modules generated from the latest Node.js version. You can get it with require('builtin-modules/static');

builtin-modules's Issues

Why is 'wasi' module not displayed?

I have a small question.
When I use the package, the wasi module was not included in the list.
But the builtin-modules.json is including it.
What is this difference?

require('repl')._builtinLibs

require('repl')._builtinLibs

I've used this in a lot of my rollup builds to exclude node builtins. Looks like it works as far back as node v0.1.3

TypeScript lib checking errors using this module

I'm using the latest TypeScript version 3.5.3 and I'm getting the following errors:

node_modules/builtin-modules/index.d.ts(12,40): error TS1005: ',' expected.
node_modules/builtin-modules/index.d.ts(12,46): error TS1005: ',' expected.

The import I'm using is import * as builtinModules from 'builtin-modules'; and the option skipLibCheck is disabled so the compiler is checking for correct typing files.

The line it complains about is the following:

declare const builtinModules: readonly string[];

It looks like the reason is that the const is additionally declared as readonly which TypeScript apperantly doesn't like. Removing the readonly fixes the error for me.

fs/promises is excluded

Not sure this is intended

`fs/promises`

Is the exclusion of fs/promises deliberate for some reason in excluding /?

Thanks!

The list is unneeded

const builtin = require('module').builtinModules;

Update list?

List is frm 3 years old, maybe it would be possible to update it and configure an automated process to keep it updated with latest versions? :-)

Missing some builtins

These are builtin modules that are part of the undocumented "private" core API but are unfortunately shimmed in browserify, and some module authors continue to prefer them over the public builtins because using them shaves a few kb off of their bundle size:

_stream_duplex
_stream_passthrough
_stream_readable
_stream_transform
_stream_writable

My root problem is that my test-runner, jest, does not recognize _stream_transform as a core module and breaks as a result. You can see I originally tried to fix it here in the module that requires _stream_transform, but as switching from _stream_transform to stream would have increased the bundle size, I am now looking for other solutions. If you are willing to add them to this module that would be great. If not (for whatever reason) I will approach jest-resolve and see if it can be addressed there.
