rollup-plugin-closure-compiler-js

library1.0.6jsnpmunverified

Rollup plugin that invokes google-closure-compiler-js to optimize bundled JavaScript. Current stable version is 1.0.6, last released in 2017. The plugin wraps the deprecated google-closure-compiler-js (Java-based via Node) but users should note that google-closure-compiler-js itself was discontinued in 2018 in favor of google-closure-compiler (which uses the Java compiler natively). Key differentiators: simple Rollup integration, passes flags directly to the compiler. However, it is considered deprecated because the underlying closure-compiler-js package is no longer maintained.

Verified usage

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

default (closure)

✓ import closure from 'rollup-plugin-closure-compiler-js'

✗ const closure = require('rollup-plugin-closure-compiler-js')

ESM default export since v1.0.0.

closure (named)

✓ import closure from 'rollup-plugin-closure-compiler-js'

✗ import { closure } from 'rollup-plugin-closure-compiler-js'

Only default export is available; named import will fail.

PluginOptions

✓ // No type export; use inline types or import from google-closure-compiler-js import type { CompileOptions } from 'google-closure-compiler-js'

✗ import { PluginOptions } from 'rollup-plugin-closure-compiler-js'

This plugin does not export TypeScript types.

Basic Rollup build that minifies the bundle using closure-compiler-js with simple optimizations.

import { rollup } from 'rollup'; import closure from 'rollup-plugin-closure-compiler-js'; async function build() { const bundle = await rollup({ input: 'src/index.js', plugins: [ closure({ compilationLevel: 'SIMPLE', languageIn: 'ECMASCRIPT6', languageOut: 'ECMASCRIPT5' }) ] }); await bundle.write({ file: 'dist/bundle.js', format: 'iife', name: 'MyLib' }); } build().catch(err => console.error(err));

Debug

Known issues

deprecatedrollup-plugin-closure-compiler-js is no longer actively maintained and relies on deprecated google-closure-compiler-js.

fix

Use @rollup/plugin-terser or rollup-plugin-esbuild for minification, or switch to the newer google-closure-compiler package with its own rollup plugin.

affects: all

breakinggoogle-closure-compiler-js was removed from npm in 2018; install will fail unless using a cached version.

fix

Pin version or switch to alternative minification plugins.

affects: >=1.0.0

gotchaThe plugin expects a default export from 'google-closure-compiler-js' but that package is discontinued.

fix

Ensure you have an older version of google-closure-compiler-js in node_modules (e.g., 20180219.0.0).

affects: all

gotchaOptions passed to closure() are directly forwarded to ClosureCompiler.compile() - must match that API exactly.

fix

Refer to google-closure-compiler-js documentation (archived) for valid flags.

affects: all

breakingRollup API changed from entry/plugins to input/plugins in v1.0; this plugin may not work with latest Rollup.

fix

Use Rollup <1.0 or ensure the plugin adapts; consider using a newer plugin.

affects: >=1.0.0

Errors

Common errors & fixes

Cannot find module 'google-closure-compiler-js'

The underlying compiler package is deprecated and may not be installable from npm.

fix

Install an archived version: npm install google-closure-compiler-js@20180219.0.0 --save-dev

TypeError: closure is not a function

Using named import instead of default import (i.e., import { closure } instead of import closure).

fix

Use default import: import closure from 'rollup-plugin-closure-compiler-js'

Error: Invalid compilation level: ADVANCED

Option values must match exact string expected by closure-compiler-js.

fix

Use valid levels: 'SIMPLE', 'ADVANCED', or 'WHITESPACE_ONLY'.
