如何在Intellij IDEA中调试打字稿

Question

Image shows my Project Structure. I am writing back-end for order app in typescript with mongoose database.I am using 'intellij-IDEA' IDE for development. Project run with gulp task runner.I am testing my api's with postman.In some cases, I am unable to track the flow of code from project. I have tried printing with 'console.log()'. But, it has limits. So, help me to debug typescript as it doesn't involve any browser activity.

Answer 1

I was able to get IntelliJ to debug Node Typescript apps while using nodemon as the node interpreter and ts-node as the inline transpiler. No need to pre-compile the code, ts-node does it real-time in memory.

// nodemon.json

{
    "execMap": {
        "js": "node",
        "ts": "./node_modules/.bin/ts-node"
    },
    "watch": [
        "app",
        "config"
    ],
    "ext": "js,ts"
}

Then run the Node.JS run configuration in Debug mode, and breakpoints are hit!

If using Linux, change the node interpreter to ./node_modules/bin/nodemon (without .cmd)
