rollup-plugin-bower-resolve

library3.1.0jsnpmunverified

A Rollup plugin that resolves module imports using the Bower resolution algorithm, allowing Rollup to bundle Bower components. Version 3.1.0 is the latest stable release, supporting Rollup v1 through v4 and Node >=14. Unlike npm-centric plugins, this plugin is specifically designed for projects that still rely on Bower for dependency management. It offers options for offline mode, custom working directories, and overrides for main entry points. The plugin is in maintenance mode as the Bower ecosystem has largely been superseded by npm/Yarn.

Code

Verified usage

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

default

✓ import bowerResolve from 'rollup-plugin-bower-resolve'

✗ const bowerResolve = require('rollup-plugin-bower-resolve')

Package is ESM-only since version 3.0.0. CommonJS require will fail.

bowerResolve

✓ const bowerResolve = require('rollup-plugin-bower-resolve').default

✗ const bowerResolve = require('rollup-plugin-bower-resolve')

If forced to use CommonJS, must access .default property.

Plugin

✓ import type { Plugin } from 'rollup'; import bowerResolve from 'rollup-plugin-bower-resolve';

TypeScript definitions are included; plugin returns Rollup Plugin object.

Shows a complete Rollup build using the plugin with Bower resolution and CommonJS support.

import { rollup } from 'rollup'; import bowerResolve from 'rollup-plugin-bower-resolve'; import commonjs from '@rollup/plugin-commonjs'; const bundle = await rollup({ input: 'src/index.js', plugins: [ bowerResolve({ cwd: process.cwd(), offline: true, module: true, jsnext: true, skip: ['some-big-dependency'] }), commonjs() ] }); await bundle.write({ file: 'dist/bundle.js', format: 'iife', name: 'MyBundle' }); console.log('Bundle created successfully.');

Debug

Known issues

breakingVersion 3.0.0 dropped support for Node <14.0.0 and switched to ESM-only exports.

fix

Update Node to >=14.0.0 and use import syntax instead of require.

affects: >=3.0.0

deprecatedThe 'jsnext' option is deprecated; use 'module' instead.

fix

Set module: true and jsnext: false to future-proof.

affects: >=0.5.0

gotchaThe 'offline' option defaults to true, which may cause build failures if Bower cache is not populated.

fix

Set offline: false to fetch from remote, or ensure bower install has been run.

affects: >=0.4.0

breakingVersion 2.0.0 requires Rollup 2.x.x and Node >=10.0.0; Rollup 1.x no longer supported.

fix

Upgrade Rollup to >=2.0.0 and Node to >=10.0.0.

affects: >=2.0.0

breakingVersion 1.0.0 removed support for Rollup versions below 1.0.0 and Node <6.0.0.

fix

Upgrade Rollup to >=1.0.0 and Node to >=6.0.0.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Cannot find module 'rollup-plugin-bower-resolve'
