google-closure-compiler-linux

What is google-closure-compiler-linux?

The google-closure-compiler-linux npm package is a tool for optimizing JavaScript. It compiles JavaScript into a more efficient form, reducing file size and improving performance. It can also check for errors and provide warnings about potential issues in the code.

What are google-closure-compiler-linux's main functionalities?

Minification

This feature allows you to minify JavaScript files, reducing their size and improving load times. The code sample demonstrates how to use the package to minify a file named 'input.js' and output the result to 'output.min.js'.

const closureCompiler = require('google-closure-compiler-linux').compiler;
const compiler = new closureCompiler({
  js: 'input.js',
  compilation_level: 'SIMPLE',
  js_output_file: 'output.min.js'
});
compiler.run((exitCode, stdOut, stdErr) => {
  if (exitCode === 0) {
    console.log('Minification successful:', stdOut);
  } else {
    console.error('Error during minification:', stdErr);
  }
});

Error Checking

This feature checks for errors and warnings in your JavaScript code. The code sample shows how to compile 'input.js' with a verbose warning level, outputting the result to 'output.js' and logging any errors or warnings.

const closureCompiler = require('google-closure-compiler-linux').compiler;
const compiler = new closureCompiler({
  js: 'input.js',
  js_output_file: 'output.js',
  warning_level: 'VERBOSE'
});
compiler.run((exitCode, stdOut, stdErr) => {
  if (exitCode === 0) {
    console.log('Compilation successful:', stdOut);
  } else {
    console.error('Errors found:', stdErr);
  }
});

Advanced Optimizations

This feature performs advanced optimizations on your JavaScript code, potentially improving performance further. The code sample demonstrates how to use the package to apply advanced optimizations to 'input.js' and output the result to 'output.adv.js'.

const closureCompiler = require('google-closure-compiler-linux').compiler;
const compiler = new closureCompiler({
  js: 'input.js',
  compilation_level: 'ADVANCED',
  js_output_file: 'output.adv.js'
});
compiler.run((exitCode, stdOut, stdErr) => {
  if (exitCode === 0) {
    console.log('Advanced optimization successful:', stdOut);
  } else {
    console.error('Error during advanced optimization:', stdErr);
  }
});

Other packages similar to google-closure-compiler-linux

uglify-js

UglifyJS is a JavaScript parser, minifier, compressor, and beautifier toolkit. It is widely used for minifying JavaScript files and offers similar functionality to google-closure-compiler-linux, though it may not provide the same level of advanced optimizations and error checking.

terser

Terser is a JavaScript parser and mangler/compressor toolkit for ES6+. It is a fork of UglifyJS and is designed to be more modern and support newer JavaScript syntax. Terser offers similar minification and compression capabilities as google-closure-compiler-linux.

babel-minify

Babel Minify (also known as babel-preset-minify) is a minifier for JavaScript based on the Babel toolchain. It provides minification and compression capabilities similar to google-closure-compiler-linux, with a focus on compatibility with Babel's ecosystem.
