js2js's Introduction

About the project

There are dozens of tools that compile some programming language to JavaScript. You can do it with C++, Java, C#, Python, Scala or Ruby. But there's one language that remains to be covered for JavaScript to dominate the world: JavaScript.

We did it. Meet js2js, a revolutionary compiler that transforms JavaScript directly to JavaScript!

Features

Control. You have full control over every single bit of the code produced by js2js. You can even compile an invalid JavaScript program to an equally invalid one.
Zero overhead. js2js will never slow you down. The compiled code has exactly the same performance as the original input.
Integration. js2js rocks with any other JavaScript technology out there: AngularJS, Emscripten, Vanilla JS, jQuery, CoffeeScript, TypeScript, and even Dart.
Cross-platform. js2js-powered code supports all kinds of stationary and mobile devices and Web browsers. Even if you develop for Netscape 2.0, we've got you covered.

Usage

For first-time usage, fetch the dependencies:

$ cd js2js
$ npm install

To compile your code, use the following command:

node js2.js -i <input_file_or_directory> -o <output_file_or_directory>

Interesting fact: you can compile the code of js2js with js2js and everything will work as expected. Check this out:

>node js2.js -i js2.js -o js2.compiled.js -v
Welcome to js2js compiler.
Compiling js2.js...
Output is written to: js2.compiled.js
Done!

Options

--decompile: decompile js2js-powered JS back to original JS.
--force: overwrite existing files in the destination location.
--verbose: toggle detailed output.

Technology

js2js is written in JavaScript and runs on Node.js. It is also available as an NPM package: js2js.

How can I contribute?

You can fork the project, make your changes and send us pull requests. Or just share it with your friends and make some JavaScript fun together with js2js.

js2js's Issues

April's fool humour wastes Google's output

I've searched Google for a real javascript javascript interpreter and had to do numerous requests to workaround this project appearing everywhere. Please, include a link to https://github.com/jterrace/js.js/ as a footnote, so that javascript developers really won't get harmed anymore.

I'm in no way affiliated with that project.

Output is exaclty the same as the input

Nothing changes. Still the same content/identation/format/lines/etc

Output file should not contain callback hell

Yeah, that's right.

Add sourcemaps generation

Could be handy for debugging

Grunt Plugin?

I'd like to incorporate this into my grunt workflow. Any timeline on a grunt plugin for this?

WONT UNZIP

Tried to unzip with JZip and no archives willunzip

Asynchrony

It would be great if js2js had asynchronous methods as well as your current synchronous ones.

formula for homebrew needed desperately!!!!

Decompiler?

I've accidentally deleted some original JavaScript source files after compiling to JavaScript. Would be great to have a --decompile option to get them back, thanks!

can I dependency inject advertising?

Then you could charge tons of cash for it.

'Js2JsCompiler.prototype.compileCode',are you kidding?

Js2JsCompiler.prototype.compileCode = function(code) {
    return code; // as we need to compile javascript to javascript, we do nothing here :)
};

Doesn't work?

I'm compiling nodejs code, but it doesn't work, output as follows:
js2js -i xScan -o xScanc -v /usr/local/bin/js2js: line 1: use strict: command not found : command not founds: line 1: : command not founds: line 2: /usr/local/bin/js2js: line 3: syntax error near unexpected token (' 'usr/local/bin/js2js: line 3:var OP = require('OptionParser');

node js2.js -i js2.js -o js2.compiled.js -v output the same file

node js2.js -i js2.js -o js2.compiled.js -v output the same file, nothing changed.
Am i not use it the right way ?????

js2js questions

Hello js2js Team,

I'm developing a serious cutting-edge application for a large enterprise. The application will store millions of records and will have very low response time. I'm planning to use jQuery plugins to show animations to the users. My app will have facebook, instagram and twitter integration.

Is your tool compatible with this kind of software and mobile screen resolutions? Could you please provide me a step-by-step tutorial and a downloadable example how can I do all of this with js2js?

PS: I have short time to deliver the software, so if I don't get any help, I have to use other tools from your competitors.

Thank you!

Thank you so much for your hard work.
