Code

Verified usage

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

default (plugin)

✓ // snowpack.config.js module.exports = { plugins: ['snowpack-plugin-closure-compiler'] }

✗ // Incorrect: trying to import as ES module import plugin from 'snowpack-plugin-closure-compiler'

This is a CommonJS package; use require or string reference in snowpack.config.js.

default (require)

✓ const scc = require('snowpack-plugin-closure-compiler'); module.exports = { plugins: [ [scc, { compilationLevel: 'ADVANCED' }] ] }

✗ const scc = require('snowpack-plugin-closure-compiler').default;

The plugin exports itself as a function; no default property.

Options interface (TypeScript)

✓ // Not exported as types; define inline interface Options { bundle?: boolean; outputFile?: string; compilationLevel?: string; languageIn?: string; languageOut?: string; }

✗ import { Options } from 'snowpack-plugin-closure-compiler'

No TypeScript declarations are shipped; use JSDoc or own types.

Configures Snowpack to run Closure Compiler with advanced optimization on all JS files, outputting a single bundle.js.

// Install: npm install --save-dev snowpack snowpack-plugin-closure-compiler google-closure-compiler // snowpack.config.js module.exports = { mount: { src: { url: '/dist' }, public: { url: '/', static: true }, }, plugins: [ ['snowpack-plugin-closure-compiler', { compilationLevel: 'ADVANCED', outputFile: 'bundle.js', bundle: true, languageIn: 'ECMASCRIPT_2020', languageOut: 'ECMASCRIPT5', }], ], };

Debug

Known issues

deprecatedSnowpack itself is deprecated; consider migrating to Vite.

fix

Replace Snowpack with Vite and use a corresponding Vite Closure Compiler plugin (e.g., vite-plugin-closure-compiler).

affects: >=2.0.0

breakingThe plugin assumes Snowpack v2 configuration format. Snowpack v3 changed the plugin API.

fix

Use with Snowpack v2 only; for v3, check compatibility or switch to another minification plugin.

affects: 1.3.2

gotchaIf bundle: true, Closure Compiler merges all JS into one file; you must set outputFile to a single value. Multiple output files are not supported.

fix

Set bundle: false if you need separate output files per input.

affects: >=1.0.0

gotchagoogle-closure-compiler is a heavy dependency (Java-based). Install time and build time may increase significantly.

fix

Consider using lighter minifiers like terser or esbuild for faster builds.

affects: >=1.0.0

deprecatedThe plugin has not been updated since 2020; languageIn/languageOut options may not support newer ECMAScript features.

fix

Use a maintained alternative or update the underlying google-closure-compiler version manually.

affects: 1.3.2

Errors

Common errors & fixes

Error: Cannot find module 'google-closure-compiler'

Missing required peer dependency google-closure-compiler.

fix

npm install --save-dev google-closure-compiler

SyntaxError: Unexpected token 'export'

Snowpack config uses ES module syntax but plugin expects CommonJS.

fix

Use module.exports = { ... } instead of export default.

The "path" argument must be of type string. Received undefined

outputFile option not provided or set to undefined when bundle: true.

fix

Set outputFile to a string (e.g., 'main.js') in plugin options.

Plugin load error: snowpack-plugin-closure-compiler is not a plugin function

Plugin imported incorrectly (e.g., using ES import or require with .default).

fix

Use the string reference in plugins array: 'snowpack-plugin-closure-compiler'.
