AstroSim uses Browserify, Babel and UglifyJS2. If you have downloaded this git repository and have the latest version of node.js installed, you can just use:
npm install
This will install all necessary tools to build AstroSim. On Windows, you can now run a build using:
bin/build.bat
On Linux or Mac, you can run a build using:
bin/build.sh
On Windows, you can run a debug build using:
bin/build-debug.bat
On Linux or Mac, you can run a debug build using:
bin/build-debug.sh
This will only run Browserify on the project, but will not use Babel to support older browsers, nor will it use UglifyJS to compress the result.
