Binary wrapper that makes your programs seamlessly available as local dependencies

Package Exports

  • bin-wrapper

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (bin-wrapper) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

bin-wrapper Build Status

Binary wrapper that makes your programs seamlessly available as local dependencies

Install

$ npm install --save bin-wrapper

Usage

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

var base = 'https://github.com/imagemin/gifsicle-bin/raw/master/vendor';
var bin = new BinWrapper()
    .src(base + '/osx/gifsicle', 'darwin')
    .src(base + '/linux/x64/gifsicle', 'linux', 'x64')
    .src(base + '/win/x64/gifsicle.exe', 'win32', 'x64')
    .dest(path.join('vendor'))
    .use(process.platform === 'win32' ? 'gifsicle.exe' : 'gifsicle')
    .version('>=1.71');

bin.run(['--version'], function (err) {
    if (err) {
        throw err;
    }

    console.log('gifsicle is working');
});

Get the path to your binary with bin.path():

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

API

.path()

Get the full path to your binary.

.version(range)
