task-closure-tools

library0.1.10jsnpmunverified

Core library for Google Closure Tools tasks, providing Compiler (JS minification using the Closure Compiler), Builder (concatenation and optional compilation), and DepsWriter (dependency graph generation for deps.js files). Current version 0.1.10, last updated June 2015 (infrequent updates). Primarily used as a base for Grunt plugins (grunt-closure-tools) and other build systems (Mantri). Differentiators: integrates directly with Google Closure Library ecosystem, supports Java-based Closure Compiler and Python-based DepsWriter, but node >=0.8.0 only, no modern ESM support.

Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

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

taskClosureTools

✓ import taskClosureTools from 'task-closure-tools'

✗ const taskClosureTools = require('task-closure-tools')

Package has no default export; common usage is via grunt plugin or requiring specific submodules.

Compiler

✓ import { Compiler } from 'task-closure-tools'

✗ const Compiler = require('task-closure-tools').Compiler

Named export available; use destructured import in ESM, or access via property in CJS.

Builder

✓ import { Builder } from 'task-closure-tools'

Named export for Builder class.

DepsWriter

✓ import { DepsWriter } from 'task-closure-tools'

Named export for DepsWriter class.

Shows basic usage of Compiler, Builder, and DepsWriter for compilation, bundling, and dependency generation.

import { Compiler, Builder, DepsWriter } from 'task-closure-tools'; // Example: compile a single JS file const compiler = new Compiler({ closureLibraryPath: './node_modules/google-closure-library', bootstrap: false }); compiler.compile({ js: 'src/main.js', compilation_level: 'ADVANCED_OPTIMIZATIONS', js_output_file: 'dist/bundle.min.js', extra_annotation_name: 'api' }, function(err, stdout, stderr) { if (err) { console.error('Compilation failed:', err); } else { console.log('Compilation succeeded:', stdout); } }); // Builder: concatenate dependencies and optionally compile const builder = new Builder({ closureLibraryPath: './node_modules/google-closure-library' }); builder.build({ inputs: 'src/main.js', compile: true, output_file: 'dist/bundle.js' }, function(err, stdout) { if (err) { console.error('Build failed:', err); } else { console.log('Build completed'); } }); // DepsWriter: generate deps.js const depsWriter = new DepsWriter({ closureLibraryPath: './node_modules/google-closure-library' }); depsWriter.writeDeps({ root: ['src', 'test'], output_file: 'dist/deps.js' }, function(err) { if (err) { console.error('Deps write failed:', err); } else { console.log('Deps written'); } });

Debug

Known issues

gotchaPackage last updated June 2015; no longer actively maintained. May have compatibility issues with modern Node.js versions (>=10).

fix

Consider using official Closure Compiler npm package 'google-closure-compiler' or other modern build tools.

affects: >=0.1.10

gotchaRequires Java Runtime Environment (JRE) to run the Closure Compiler and Python to run DepsWriter. Not explicitly mentioned in npm metadata.

fix

Ensure Java and Python are installed and available in PATH.

affects: >=0.1.0

gotchaClosure Library path must be provided manually via options; package does not automatically resolve it.

fix

Install google-closure-library and pass its path (e.g., './node_modules/google-closure-library').

affects: >=0.1.0

gotchaCompiler and Builder options are passed directly to the underlying Java command; incorrect flags may cause silent failures.

fix

Refer to official Closure Compiler documentation for valid compilation_level and other options.

affects: >=0.1.0

Errors

Common errors & fixes

Error: Cannot find module 'task-closure-tools'

Package not installed or incorrect import path.

fix

Run `npm install task-closure-tools` and use require('task-closure-tools') or import { ... } from 'task-closure-tools'.

Java not found. Please install Java.

Java Runtime Environment not installed or not in PATH.

fix

Install Java (JRE) version 8 or later and ensure java command is accessible.

python: not found

Python not installed for DepsWriter.

fix

Install Python 2.7 (older, may work) or Python 3 and ensure python command is in PATH.

TypeError: taskClosureTools is not a function

Using default import instead of named exports.

fix

Use named imports: import { Compiler, Builder, DepsWriter } from 'task-closure-tools'.

Error: ENOENT: no such file or directory, open '.../closure-library/closure/goog/base.js'

Closure Library path not correctly configured or missing.

fix

Set closureLibraryPath option to the root of the installed google-closure-library package.
