node-cc-runner

Client for Closure Compiler web runner.

Install

npm install cc-runner

Usage

var runner = require('cc-runner');
var compiler = runner.create();

compiler.on('listening', () => {
  compiler.status((error, res) => {
    console.log(res);
  });

  compiler.compile({
    optimizations: {
      level: "SIMPLE_OPTIMIZATIONS"
    },
    sources: [{
      fileName: 'bar.js',
      code: '(console.log(function(){return 42-9;}));'
    }]
  }, (error, res) => {
    console.log(res);
  });
});

API

create()

Returns compiler instance. Compiler is EventEmitter.

compiler

Event: 'online'

Event: 'listening'

Emitted when Closure Compiler runner server is listening for connections.

Event: 'error'

Forwards all errors.

compiler.status(options, callback)
