demoProject已经在3000端口中运行了 至此,我们已经基本认识Express安装、结构以及运行,接下来呢,我们使用Express+NodeJS+MySQL做一个简单的实例。 使用Express+NodeJS+MySQL实现基本业务逻辑增删改查,只有增是粗体,那就只实现增一个喽。 实践环境:SystemOS:Ubuntu Database:MySQL DevLanguage:NodeJS NodeJS-Frame:Expres...
The Node.js app is defined in the fileserver.js, located in the directory for the web role (WebRole1by default). Here's the code: JavaScript varhttp =require('http');varport = process.env.port ||1337; http.createServer(function(req, res){ res.writeHead(200, {'Content-Type':'text/...

Chakra引擎内建的实现。可以看到的是,其await实现与yield实现类似。yield和await在token解析时大多相邻甚至写在一起,最后到下面那个函数都以类型Js::OpCode::Yield进行处理。所以整块Chakra中,出现await的基本只有Parser部分。比如ByteCodeEmitter::Emit内:
$ node example/async.js /home/substack/projects/node-resolve/node_modules/tap/lib/main.js synchronously resolve: var resolve = require('resolve/sync'); // or, `require('resolve').sync var res = resolve('tap', { basedir: __dirname }); console.log(res); $ node example/sync.js /ho...
