NwSJS

No White Space JavaScript

Simple, lightweight, ES6 compliant, cross-platform CLI utility to strip whitespace and comments from Javascript source code.

Usage

Running

Linux

$ ./nwsjs srcFile.js > outFile.js

Windows

> nwsjs.exe srcFile.js > outFile.js

Note: srcFile.js and outFile.js must NOT be the same file!

Using From NPM

Installing

Linux

$ npm install nwsjs

or

$ npm install -g nwsjs

Windows

> npm install --no-bin-links nwsjs

Note: Bin links for Windows do NOT work properly currently. Therefore, installing NwSJS globally on Windows is NOT supported. NwSJS will therefore be installed to node_modules\nwsjs\nwsjs.exe on Windows.

Running

Linux

$ ./node_modules/.bin/nwsjs

or

$ ./node_modules/nwsjs/nwsjs

or (if installed globally)

$ nwsjs

Windows

> node_modules\nwsjs\nwsjs

Building

Linux

$ bash build.bash

Windows

> build

Note: Building requires that g++ be available on your PATH for both Linux and Windows.

Testing

Download dependencies for testing

npm install

Run test suite

npm test

Note: For Windows users, running tests requires the availability of a valid bash.exe on your %PATH%.

Testing Process

NwSJS is tested against Microsoft's Typescript compiler and the Browserify Javascript bundler. Every .js file pulled in by Typescript, Browserify, as well as the various front end and backend frameworks pulled in by the test files are first compressed. The .ts files under tests are then compiled. If NwSJS crashes or the compiler raises an error while compiling then the test fails.

Each compiled .ts file is then bundled using Browserify. The resulting bundles are then compressed. The compressed and uncompressed bundles are run and their return codes are compared. If the return codes differ, then the test fails.

Note: See test.bash for full process and more notes.
