Node.js 7.x异步/等待支持演示-Node.js开发

## Node.js v7 async/await demo ### What is this? Node.js v7.x.x ships with experimental async/await support, greatly simplifying boilerplate required for writing modern server side code. This project is a demonstration of the minimal setup in order to use the new async/await features in Node. NOTE: async/await are not officially supported in Node.js v7.x at this point. You are welcome to try things out, but there may be no support if you encounter bugs. ### Node.js v7 - simple setup (recommended) Download and install node.js v7 release version for your platform from https://nodejs.org ``` https://nodejs.org ``` ### Node.js v7 - setup using node version manager (nvm) Go to http://nvm.sh and follow the instructions on installing nvm for your platform. Afterwards, run: ``` nvm install 7 nvm use 7 ``` ### Run the demo Currently async / await support ships under --harmony-async-await flag. npm start command executes `node --harmony-async-await index.js` ``` npm install npm start ``` ### What does not work While async/await is a great addition, some things like ES6 module support (`import x from 'x'`) and arrow function support in class declaration (`class A { b() => {} }`) are still not supported. If you use these features you might still want to keep a ES6/ES7 -> ES5 transpiler like Babel.
