node demo项目搭建及打包

Node demo项目搭建及打包

1. 下载安装node.js，地址http://nodejs.cn/
2. 打开cmd验证下是否安装成功

1. 全局安装Express

1. 全局安装express-generator

1. 然后输入express 项目名

1. 至此打开文件目录你会发现多了个myapp1的项目

1. 我们在src 下新建个server.js这边使用的是websocket的demo
2. var WebSocketServer = require('websocket').server;
   var http = require('http');
   
   var server = http.createServer(function(request, response) {
       // console.log((new Date()) + ' Received request for ' + request.url);
       response.writeHead(404);
       response.end();
   });
   const port = 8099
   server.listen(port, function() {
       // console.log((new Date()) + ' Server is listening on port ' + port);
   });
   
   wsServer = new WebSocketServer({
       httpServer: server,
       // You should not use autoAcceptConnections for production
       // applications, as it defeats all standard cross-origin protection
       // facilities built into the protocol and the browser.  You should
       // *always* verify the connection's origin and decide whether or not
       // to accept it.
       autoAcceptConnections: false
   });
   
   function originIsAllowed(origin) {
       // put logic here to detect whether the specified origin is allowed.
       return true;
   }
   
   wsServer.on('request', function(request) {
       if (!originIsAllowed(request.origin)) {
           // Make sure we only accept requests from an allowed origin
           request.reject();
           console.log((new Date()) + ' Connection from origin ' + request.origin + ' rejected.');
           return;
       }
   
       var connection = request.accept('echo-protocol', request.origin);
       // console.log((new Date()) + ' Connection accepted.');
       connection.on('message', function(message) {
           if (message.type === 'utf8') {
               // console.log('Received Message: ' + message.utf8Data);
               connection.sendUTF(message.utf8Data);
           }
           else if (message.type === 'binary') {
               // console.log('Received Binary Message of ' + message.binaryData.length + ' bytes');
               connection.sendBytes(message.binaryData);
           }
       });
       connection.on('close', function(reasonCode, description) {
           // console.log((new Date()) + ' Peer ' + connection.remoteAddress + ' disconnected.');
       });
   });

那么该如何打包呢？

我们这边使用pkg进行打包

1. 全局安装pkg，npm install -g pkg
2. 我们修改package.json文件

1. 执行pkg package.json

1. 至此项目目录下会出现以下三个文件

直接运行就可以了
