用Typescript 開發 node.js

文檔1:

1. 運行命令   tsc --init
2. 修改  tsconfig.json文件

   "outDir": "./bin",                        
   "rootDir": "./src", 

3. 建立 src 文件夾, 添加  Hello.ts 文件

class Hello {
    firstName : string;
    lastName : string;
    constructor(fiestName : string,  lastName : string) {
        this.firstName = fiestName;
        this.lastName = lastName;
        console.log(`Hello ${fiestName} ${lastName}`)
    }
    greeter() {
        console.log( "歡迎來到typescript的世界，hello" +
            this.firstName + " " + this.lastName);
    }
}
var user = new Hello("王", "小二");
user.greeter();

　　4. 運行編譯命令   tsc

　　5. 運行程序  node bin/Hello.js
