library0.2.12jsnpmunverified

Node.js wrapper for Google's Closure Compiler Java tool. v0.2.12 – stable but infrequent releases, last updated 2019. Runs the Closure Compiler JAR in a child process and returns compiled JavaScript via callback. Provides a simple API for advanced compilation and dead code elimination, but requires Java runtime. Alternatives like google-closure-compiler offer more frequent updates.

Code

Verified usage

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

compile

✓ import { compile } from 'closure-compiler'

✗ const cc = require('closure-compiler'); cc.compile()

Named export, not default.

default (whole module)

✓ import * as cc from 'closure-compiler'

✗ import cc from 'closure-compiler'

No default export; use namespace import for require style.

compile

✓ const { compile } = require('closure-compiler')

✗ const compile = require('closure-compiler')

Required as property destructure.

Compile a JavaScript file with advanced optimizations using Closure Compiler asynchronously.

import { compile } from 'closure-compiler'; import { readFileSync } from 'fs'; const code = readFileSync('input.js', 'utf8'); compile(code, { compilation_level: 'ADVANCED_OPTIMIZATIONS' }, (err, stdout, stderr) => { if (err) { console.error('Compilation error:', stderr); process.exit(1); } console.log(stdout); });

Debug

Known issues

gotchaRequires Java installed on PATH to run the Closure Compiler JAR.

fix

Install Java Runtime Environment (JRE) and ensure java is in PATH.

affects: all

deprecatedThis package uses callbacks; no Promise support natively.

fix

Wrap compile() in a Promise manually or use a wrapper.

affects: <0.3

gotchaOptions are passed as command-line flags; array values become repeated flags.

fix

For array options, set as array in options object; the wrapper handles repetition.

affects: all

Errors

Common errors & fixes

Error: Command failed: java -jar <path> ... exit code 1

Closure Compiler JAR not found or Java not installed.

fix

Ensure java is installed and closure-compiler.jar is bundled.

Use named import: import { compile } from 'closure-compiler'
