bin-wrapper

Binary wrapper for Node.js that makes your programs seamlessly available as local dependencies

Getting started

Install with npm: npm install bin-wrapper

Examples

All platform and arch specific options takes precedence over the base options. See test.js for a full fleshed example.

var Bin = require('bin-wrapper');

var opts = {
    name: 'Gifsicle',
    bin: 'gifsicle',
    path: 'vendor',
    url: 'http://url/to/gifsicle',
    src: 'http://www.lcdf.org/gifsicle/gifsicle-1.71.tar.gz',
    buildScript: './configure --bindir="vendor" && make install',
    platform: {
        win32: {
            bin: 'gifsicle.exe',
            url: [
                'http://url/to/gifsicle.exe'
                'http://url/to/gifsicle.dll'
            ]
        }
    }
}
var bin = new Bin(opts);

bin.check('--version', function (works) {
    if (!works) {
        console.log('Pre-build test failed, compiling from source');
        return bin.build();
    }

    console.log('Binary passed the test');
});

Get the path to your binary with bin.path.

console.log(bin.path);
// => path/to/vendor/gifsicle

API

.check(cmd, cb)
