closure-compiler-stream

library0.1.15jsnpmunverified

A streaming interface for Google Closure Compiler that provides full pipe support for Node.js streams. Version 0.1.15 is the latest stable release. It wraps the Closure Compiler Java application as a Node.js stream, allowing it to be used in gulp pipelines or with plain streams. Key differentiators from other Closure Compiler wrappers are its simple stream-based API and support for Gulp with sourcemaps. It supports module definitions and custom jar paths. The package is minimal and focuses on streaming rather than complex configuration.

Verified usage

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

default

✓ const closure = require('closure-compiler-stream');

✗ import closure from 'closure-compiler-stream';

This package uses CommonJS. ESM import may not work without a bundler.

default

✓ import closure from 'closure-compiler-stream';

If using a bundler or ESM environment, default import works (package has no named exports).

default

✓ var closure = require('closure-compiler-stream');

✗ var closure = require('closure-compiler-stream').default;

Do not access .default; the module directly exports the function.

Creates a read stream from a source file, pipes through the Closure Compiler, and writes the minified output to another file.

const closure = require('closure-compiler-stream'); const fs = require('fs'); // Compile JavaScript from a file and output to another file fs.createReadStream('input.js') .pipe(closure()) .pipe(fs.createWriteStream('output.min.js')); // Or with options fs.createReadStream('input.js') .pipe(closure({ compilation_level: 'SIMPLE_OPTIMIZATIONS' })) .pipe(fs.createWriteStream('output.min.js'));

Debug

Known issues

gotchaThe module requires Java to be installed because it spawns the Closure Compiler Java jar.

fix

Ensure Java (JRE) is installed and available in PATH.

affects: >=0.1.0

gotchaOptions passed to the stream are flags for the Closure Compiler. Not all options are validated; misspelled flags may be ignored silently.

fix

Refer to the Closure Compiler flags documentation and use correct flag names.

affects: >=0.1.0

gotchaThe stream returns a Writable stream but is intended to be used in a pipeline; piping to it will cause it to consume input and produce output on the next stream.

fix

Always pipe from a readable stream into closure() and then to a writable stream.

affects: >=0.1.0

deprecatedThe package is not actively maintained; last release was 0.1.15 in 2016. Consider using more modern alternatives like google-closure-compiler.

fix

Migrate to google-closure-compiler package which provides a similar API and is actively maintained.

affects: >=0.1.0

Errors

Common errors & fixes

Error: spawn java ENOENT

Java is not installed or not in PATH.

fix

Install Java (JRE) and ensure 'java' command is available.

Error: write after end

Attempting to write to the stream after it has ended, often due to incorrect piping.

fix

Ensure piping is set up correctly: source.pipe(closure()).pipe(dest);

TypeError: closure is not a function

Importing the module incorrectly, e.g., as an ESM default import without bundler or using .default.

fix

Use require('closure-compiler-stream') and call it directly as closure().
