怎么运行Typescript

依据官方示例：

npm i -g typescript

 

示例：tsc *.ts

实例：tsc hello.ts

 

不过以上实现的太有限制了，如下实现可满足正常测试以及学习使用

 

package,json

{
    "name": "TypeScript",
    "version": "1.0.0",
    "description": "",
    "main": "index.js",
    "scripts": {
        "test": "echo \"Error: no test specified\" && exit 1",
        "start": "concurrently \"npm run tswatch\" \"npm run lite\"",
        "tsc": "tsc",
        "tswatch": "tsc -w",
        "lite": "lite-server"
    },
    "dependencies": {
        "core-js": "2.5.7",
        "classlist.js": "1.1.20150312",
        "systemjs": "0.21.4",
        "bootstrap": "4.1.3"
    },
    "devDependencies": {
        "concurrently": "^3.6.1",
        "lite-server": "^2.4.0",
        "typescript": "^2.9.2",
        "typings": "^2.1.1"
    },
    "keywords": [],
    "author": "",
    "license": "ISC"
}

 

tsconfig.json

{
    "compilerOptions": {
        "target": "es5",
        "module": "commonjs",
        "moduleResolution": "node",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "lib": [
            "es2016",
            "dom"
        ]
    },
    "exclude": ["node_modules"]
}

 

 

 

1.npm install

2.新建html文件,引入print.js，新建一个print.ts

3.npm start(执行完后会生成一个print.js文件,随后打开index.html，最后运行)
