TypeScript环境配置

2019-08-14 本文已影响0人 JunChow520

TypeScript是由微软开发的一款开源的编程语言
TypeScript是JavaScript的超集，遵循最新的ES6、ES5规范。
TypeScript扩展了JavaScript的语法
TypeScript更像是后端Java、C#这样面向对象语言，可以让JS开发大型企业应用。
Google也在大力支持TypeScript的推广，Google的Angular2.x+也是基于TypeScript语法的。
最新的VUE、React也可以集成TypeScript

TypeScript与ES5、ES6的关系

安装编译

$ npm i -g typescript

$ tsc -v
Version 3.5.3

$ vim hello.ts
console.log("hello world")
$ tsc hello.ts
$ node hello.js

WebStorm提供了创建TypeScript的模板文件，但并没提供自动编译TS文件为JS文件和Map文件。

配置File Watcher来对TS文件进行自动编译

创建项目添加tsconfig.json文件
File > new > tsconfig.json File
为TypeScript设置编译配置
File > Settings > Tools > File Watcher > TypeScript
