rollup-all

1.10.6 verified Mon Apr 27 auth: no javascript

Rollup-all is a build tool that wraps Rollup to automatically generate CommonJS, ES module, and browser (IIFE/UMD) bundles from a single source, with built-in Babel and TypeScript support. Current stable version is 4.0.0 (August 2025), with active development and semantic versioning. It differentiates from raw Rollup by providing an opinionated, zero-config setup that handles multiple output formats, minification, asset copying, and type definition file generation without manual configuration. Notable breaking changes occurred in v3.0.0 (format configuration restructured) and v4.0.0 (defaults moved to config root). Supports Node.js 12+ and is primarily used for library development.

Common errors

error Error: Cannot find module 'rollup' ↓

cause Rollup is a peer dependency not installed.

fix

npm install --save-dev rollup

error TypeError: config is not a function ↓

cause Using default import instead of named import for 'config'.

fix

Use 'import { config } from 'rollup-all'' or 'const { config } = require('rollup-all')'.

error Error: No configuration found. Create a rollup.config.js file or use --config flag. ↓

cause Missing configuration file or incorrect file name.

fix

Ensure a rollup.config.js file exists at project root, or run rollup-all with explicit config path.

error src/index.ts(1,1): error TS2304: Cannot find name 'require'. ↓

cause Using CommonJS require in a TypeScript file without node types.

fix

Install @types/node and ensure tsconfig includes 'moduleResolution': 'node' and 'allowSyntheticDefaultImports': true.

Warnings

breaking In v4.0.0, config.defaults is removed and must be placed at config root level. ↓

fix Move any options previously under config.defaults to the root of the config object.

breaking In v3.0.0, the way build formats are enabled changed. It now uses a format-specific configuration object. ↓

fix Update your rollup.config.js to use the new format enablement structure: e.g., config({ distConfig: { enabled: true } }) instead of previous format.

gotcha The package requires certain Babel presets and plugins to be installed as peer dependencies. Missing them causes build failures. ↓

fix Install @babel/core, @babel/preset-env, @babel/preset-typescript, @babel/runtime, and @babel/plugin-transform-runtime as devDependencies.

gotcha TypeScript projects must have typescript installed as a devDependency. Rollup-all does not include it automatically. ↓

fix Ensure 'typescript' is in your devDependencies.

deprecated The 'uglify' option is deprecated in favor of 'minified'. ↓

fix Use 'minified: true' instead of 'uglify: true' in the config object.

Install

npm install rollup-all

yarn add rollup-all

pnpm add rollup-all

Imports

config

wrong

import rollupAll from 'rollup-all'

correct

import { config } from 'rollup-all'

config is a named export, not default. ESM since v3.

rollupAll
wrong
```
const rollupAll = require('rollup-all')
```
correct
```
import * as rollupAll from 'rollup-all'
```
CJS still works via require, but named destructuring is the modern pattern.
types (ConfigOptions)
wrong
```
import { ConfigOptions } from 'rollup-all'
```
correct
```
import type { ConfigOptions } from 'rollup-all'
```
ConfigOptions is a TypeScript type export, not a value. Use 'import type' or 'import { type ConfigOptions }'.

Quickstart

Covers installation, npm script setup, and optional configuration with config() function including babel presets and build options.

npm install --save-dev rollup-all

// package.json
{
  "scripts": {
    "build": "rollup-all"
  }
}

// rollup.config.js (optional)
const { config } = require('rollup-all');

module.exports = config({
  config: {
    sourcemap: true,
    uglify: true,
    assets: ['assets/**'],
    distConfig: { enabled: true }
  },
  babelConfig: {
    presets: [['@babel/preset-env', { targets: '> 0.25%' }]],
    plugins: ['@babel/plugin-proposal-optional-chaining']
  }
});

// Then run: npm run build
