install-nw

Quickly and robustly install and cache NW.js.

Installs the nw module, which in turn installs NW.js. install-nw compliments nw by implementing resumable, multi-threaded downloads and archive caching.

Usage

In package.json

This module is mainly intended for usage as a caching install mechanism for other modules.

npm i --save install-nw

It installs an executable in local to a project in node_modules/.bin, since NPM sets this folder as your path during install, we can simply do this in our package.json

{
  "scripts" : { 
    "postinstall": "install-nw"
  },
  "nw": "0.12.0-1"
}

Note the addition of the nw field, this holds the version of NW.js to install.

npm arguments and environment variables

Cache

npm install --nwjs_cache=/path/to/cache

export NWJS_CACHE=/path/to/cache
npm install

This can also be added to an .npmrc file:

nwjs_cache=/path/to/cache

See CLI cache argument for details

URL Base

npm install --nwjs_urlbase=https://my.nwjs.repo/v

export NWJS_CACHE=https://my.nwjs.repo/v
npm install

This can also be added to an .npmrc file:

nwjs_urlbase=https://my.nwjs.repo/v

See CLI urlBase argument for details

CLI

It can be used as a global install too,

npm -g install install-nw
install-nw 0.12.0-1  

Not supplying a version will result in the latest NW.js version.

cache

nw-install will install to the default cache location (~/.nw-cache), to install else where (say to ~/Applications), simply pass a --cache argument.

install-nw --cache ~/Applications

urlBase

The default urlBase is as per the nw module: http://dl.nwjs.io/v

This can be changed with a --urlBase argument:

install-nw --urlBase https://my.nwjs.repo/v

Programmatic

nw-install can also be used programmatically

var install = require('nw-install');
var opts = {
  filePath: '/path/to/save/nwjs/zipfile', 
  url: ' http://dl.nwjs.io/v0.12.0-1/nwjs-v0.12.0-1-osx-x64.zip',
  version: '0.12.0-1',
  isGlobal: false
};

install(opts, function (err) {
  if (err) { 
    console.log(err.message); 
    return process.exit(err.code);
  }

  process.exit();
});
