Download: http://dl.node-webkit.org/

Basic Operation (Window System):

1, download the Node-webkit version of the system, run the Nw.exe in the directory, the display instructions can be run normally.

2, the establishment of Package.json and index.html, compressed into Test.zip file package, directly dragged to the Test.zip package to Nw.exe to open Nw.exe mode.

3, the Text.zip and Nw.exe packaged into Test.exe,window may command

Copy/b Nw.exe+test.ziptest.exe

Now run the Test.exe directly to open it.

Note: Nw.exe must be placed in front of the + sign, the merge command needs to be executed with CMD, win8 "Copy-item: Cannot find the positional parameters that accept the actual parameter ' B.exe '."

4, install Enigma Virtual Box (http://enigmaprotector.com/en/aboutvb.html), packaging all files for an executable EXE program.

Package.json:

Package.json is a project configuration file that configures window borders, toolbars, fullscreen, window size and position when open, icons, node. js startup files, default open pages, window maximum and minimum dimensions, and so on. The default page setting is main. For detailed parameters, see:

node. JS Module Extensions:

Http.js:

var PORT = 8000;var http = require (' http '), var url = require (' URL '), var path = require (' path '); var fs = require (' FS '); var MIME = require ('./mime '). Types;var Server = http.createserver (function (request, response) {var pathname = Url.parse (r    Equest.url). Pathname; var realpath = "Test" + pathname;var ext = path.extname (realpath); ext = ext? Ext.slice (1): ' Unknown '; var contentType = Mime[ext] | |    "Text/plain"; Path.exists (Realpath, function (exists) {if (!exists) {Response.writehead (404, {' Conte             Nt-type ': ContentType});            Response.Write ("This request URL" + pathname + "is not found on the this server.");        Response.End (); } else {fs.readfile (Realpath, "binary", function (err, file) {if (err) {RE                     Sponse.writehead ($, {' Content-type ': ContentType});                Response.End (ERR);          } else {          Response.writehead ($, {' Content-type ': ContentType});                     Response.Write (File, "binary");                Response.End ();        }            }); }    });}); Server.listen (port); Console.log ("Server runing at Port:" + Port + ".");

Package.json:

{  "name": "Nw-demo",  "main": "Http://localhost:8000/test.html",  "Nodejs": True,  "Node-main": " Http.js ",  " window ": {" width ": +," height ": +," Transparent ": True  }}

Mime.js:

Exports.types = {    "css": "Text/css",    "gif": "Image/gif",    "html": "Text/html",    "ico": "Image/x-icon",    "JPEG": "Image/jpeg", "    jpg": "Image/jpeg",    "JS": "Text/javascript",    "JSON": "Application/json",    "PDF": "Application/pdf",    "png": "Image/png",    "svg": "Image/svg+xml",    "swf": "application/ X-shockwave-flash ",    " TIFF ":" Image/tiff ",    " TXT ":" Text/plain ",    " wav ":" Audio/x-wav ",    " WMA ":" Audio/x-ms-wma ",    " wmv ":" Video/x-ms-wmv ",    " xml ":" Text/xml "};<strong></strong>

Node-webkit Disadvantages:

After the final packaging of the file larger, simple node-webkit required files will be nearly 60M, compression will also be nearly 25M.
