node-webkit is renamed NW.js

Official site: https://nwjs.io

Introduction

NW.js is an app runtime based on Chromium and node.js. You can write native apps in HTML and JavaScript with NW.js. It also lets you call Node.js modules directly from the DOM and enables a new way of writing native applications with all Web technologies.

It was created in the Intel Open Source Technology Center.

Features

Apps written in modern HTML5, CSS3, JS and WebGL.
Complete support for Node.js APIs and all its third party modules.
Good performance: Node and WebKit run in the same thread: Function calls are made straightforward; objects are in the same heap and can just reference each other.
Easy to package and distribute apps.
Available on Linux, Mac OS X and Windows.

Demos and real apps

Quick Start

Create index.html:

<!DOCTYPE html>
<html>
  <head>
    <title>Hello World!</title>
  </head>
  <body>
    <h1>Hello World!</h1>
    We are using node.js <script>document.write(process.version)</script>.
  </body>
</html>

Create package.json:

{
  "name": "nw-demo",
  "version": "0.0.1",
  "main": "index.html"
}

Run:

$ /path/to/nw .  (suppose the current directory contains 'package.json')

Note: on Windows, you can drag the folder containing package.json to nw.exe to open it.

Note: on OSX, the executable binary is in a hidden directory within the .app file. To run node-webkit on OSX, type:
/path/to/nwjs.app/Contents/MacOS/nwjs . (suppose the current directory contains 'package.json')

Community

We use the google group as our mailing list (use English only). Subscribe via nwjs-general+subscribe@googlegroups.com.

NOTE: Links to the old google group (e.g. https://groups.google.com/forum/#!msg/node-webkit/doRWZ07LgWQ/4fheV8FF8zsJ) that are no longer working can be fixed by replacing node-webkit with nwjs-general (e.g https://groups.google.com/forum/#!msg/nwjs-general/doRWZ07LgWQ/4fheV8FF8zsJ).

Issues are being tracked here on GitHub.

The source code for NW.js and the daily development spans multiple repositories in this organization. This repository is for issue tracking, landing page, and part of the source code.

Verifying Binaries

Starting from 0.32.0 the stable and nightly download directories contain a SHASUMS256.txt file that lists the SHA checksums for each file available for download, as well as the checksums for the files inside the download package.

The SHASUMS256.txt can be downloaded using curl.

$ curl -O https://dl.nwjs.io/vx.y.z/SHASUMS256.txt

To check that a downloaded file matches the checksum, run it through sha256sum with a command such as:

$ grep nwjs-vx.y.z.tar.gz SHASUMS256.txt | sha256sum -c -

The stable releases (but not Nightlies) also have the GPG detached signature of SHASUMS256.txt available as SHASUMS256.txt.asc. You can use gpg to verify that SHASUMS256.txt has not been tampered with.

To verify SHASUMS256.txt has not been altered, you will first need to import the GPG key of NW.js maintainer to create releases. Use this command to import the key:

$ gpg --keyserver pool.sks-keyservers.net --recv-keys 78680FA9E21BB40A

(Key fingerprint is 1E8B EE8D 5B0C 4CBC D6D1  9E26 7868 0FA9 E21B B40A)

Next, download the SHASUMS256.txt.asc for the release:

$ curl -O https://dl.nwjs.io/vx.y.z/SHASUMS256.txt.asc

After downloading the appropriate SHASUMS256.txt and SHASUMS256.txt.asc files, you can then use gpg --verify SHASUMS256.txt.asc SHASUMS256.txt to verify that the file has been signed by an authorized member of the NW.js team.

Once verified, use the SHASUMS256.txt file to get the checksum for the binary verification command above.
