rollup-worker

library2.0.1jsnpmunverified

A CLI tool that wraps Rollup with built-in plugins for simplified, zero-config bundle management across multiple entry points. Version 2.0.1, with a next tag for latest releases. Key differentiators: plugin aliases (e.g., 'resolve', 'typescript', 'babel') that auto-configure, per-entry plugin overrides via functions, and a default config file (.fssrc.js). Targets Node >=7.10.1, and supports common formats (ESM, CJS, UMD, IIFE). Less flexible than raw Rollup but reduces boilerplate for multi-bundle workflows.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

cli usage

✓ npx rollup-worker -c .fssrc.js

✗ require('rollup-worker')

rollup-worker is a CLI tool, not a library. Importing as a Node module will not work as expected.

config export

✓ module.exports = { ... }

✗ export default { ... }

Config file .fssrc.js must use CommonJS to export config object, even if your project is ESM.

plugin list

✓ const plugins = ['resolve', 'typescript'];

✗ const plugins = ['nodeResolve', 'ts'];

Plugin names are specific: 'resolve' (not 'nodeResolve'), 'typescript' (not 'ts'), 'commonjs', 'babel', 'globals', 'node-builtins'.

Minimal config file showing plugin aliases, per-entry overrides, and multiple output formats.

// .fssrc.js const { version, name, author, dependencies } = require('./package.json') const banner = `/*! ${name} v${version} | MIT licensed. | by ${author} */` module.exports = { plugins: { resolve: () => ({ preferBuiltins: false }), commonjs: {}, babel: (cfg) => ({ comments: cfg.output.format !== 'iife' }), replace: { __VERSION__: version } }, entry: [ { input: './src/main.js', plugins: ['resolve', 'commonjs', 'babel'], output: [ { format: 'es', file: 'dist/bundle.esm.js' }, { format: 'cjs', file: 'dist/bundle.cjs.js', banner } ] } ] }

Debug

Known issues

deprecatedThe 'next' install tag (npm i -g rollup-worker@next) is deprecated; use latest instead.

fix

Install with 'npm i -g rollup-worker@latest' or just 'npm i -g rollup-worker'.

affects: >=2.0.0

gotchaPlugin alises may conflict with older Rollup plugin names; e.g., 'resolve' maps to @rollup/plugin-node-resolve but behavior differs.

fix

Check internal plugin mapping for each alias; override plugin config via function to control options.

affects: all

gotchaConfig file .fssrc.js must export via module.exports, not export default; failing silently yields no output.

fix

Use CommonJS export: module.exports = { ... }.

affects: all

gotchaPlugin configuration functions receive { output, ... } , but some plugins expect different signature (e.g., typescript receives rollupCfg).

fix

Inspect plugin source or log the argument: plugins: { myPlugin: (cfg) => { console.log(cfg); return {}; } }.

affects: >=2.0.0

Errors

Common errors & fixes

Error: Cannot find module '@rollup/plugin-node-resolve'

rollup-worker does not bundle all Rollup plugins; they must be installed separately if not included by default.

fix

Install the missing plugin: npm install --save-dev @rollup/plugin-node-resolve

Unexpected token: punc (.)

Config file uses ESM syntax (e.g., import/export) but rollup-worker expects CJS.

fix

Convert to CommonJS: replace 'export default' with 'module.exports ='.

Error: Could not resolve 'fs' (or other Node built-in)

Rollup by default externalizes Node built-ins, but 'node-builtins' plugin must be enabled to shim them.

fix

Add 'node-builtins' to the plugins array.
