webpack-rxjs-externals

2.0.0 verified Sat Apr 25 auth: no javascript

Generate webpack externals configuration for RxJS v6+ automatically, avoiding manual maintenance of external module lists. Version 2.0.0 requires webpack >=2 and only supports RxJS v6 import paths (e.g., 'rxjs', 'rxjs/operators'), not the older v5 deep paths. This package is specifically for bundling RxJS separately from your app bundle via CDN or external script. Notable alternatives: manually listing externals or using webpack-node-externals. Maintained sporadically; last release 2.0.0.

Common errors

error Module not found: Can't resolve 'rxjs/operators' ↓

cause Using v5 deep path pattern 'rxjs/operators' is correct for v6, but if RxJS v5 is installed or paths are wrong, webpack may fail.

fix

Ensure RxJS v6+ is installed and use correct paths: 'rxjs' and 'rxjs/operators'.

error TypeError: webpackRxjsExternals is not a function ↓

cause Attempting named import instead of default import.

fix

Use import webpackRxjsExternals from 'webpack-rxjs-externals';.

Warnings

breaking Version 2.0.0 only supports RxJS v6+ import paths. Older v5 deep paths (e.g., 'rxjs/operator/map') are NOT supported. ↓

fix Use version 1.1.0 if you need v5 deep path support.

breaking Requires webpack >=2.0.0. Not compatible with webpack 1.x. ↓

fix Upgrade webpack to 2.x or later.

deprecated Package development is sparse; no updates since 2020. Consider manually specifying externals for recent RxJS versions or using webpack-node-externals. ↓

fix Manually update externals list or switch to alternative library.

Install

npm install webpack-rxjs-externals

yarn add webpack-rxjs-externals

pnpm add webpack-rxjs-externals

Imports

default (webpackRxjsExternals)

wrong

const webpackRxjsExternals = require('webpack-rxjs-externals');

correct

import webpackRxjsExternals from 'webpack-rxjs-externals';

Package uses default export, ESM import preferred. CJS require also works.

webpackRxjsExternals (named)

wrong

const { webpackRxjsExternals } = require('webpack-rxjs-externals');

correct

import { webpackRxjsExternals } from 'webpack-rxjs-externals';

No named export exists; must use default import. Common mistake.

Quickstart

Shows how to integrate webpack-rxjs-externals into webpack config to externalize RxJS v6 imports.

// webpack.config.js
import webpackRxjsExternals from 'webpack-rxjs-externals';

export default {
  externals: [
    webpackRxjsExternals(),
  ],
};

// Entry file
import { of } from 'rxjs';
import { map } from 'rxjs/operators';

of(1, 2, 3).pipe(map(d => d * 10));
