vscode中调试ts

ts-node命令

一、新建ts文件
二、debug 添加配置

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [

        {
            "name": "Debug ts",
            ​
            "type": "node",
            ​
            "request": "launch",
            ​
            "runtimeArgs": ["-r", "ts-node/register"],//核心
            ​
            "args": ["${workspaceFolder}/hello.ts"]​
        }
    ]
}

三、当前目录添加局部 ts ts-node

npm i typescript ts-node

自动编译

tsc --init

修改生成json的outDir 即编译后的js目录
