A minimal setup to Debug TypeScript on Node in VSCode

Please note that this repository serves as an example of one way that I've found to set up a minimal project which allows for debugging TypeScript that is running on Node in VSCode. At the time of writing I've only tested on a x64 based Windows 10 machine and have not verified that the same steps work in a multitude of other configurations or environments. Please note also the prerequisites as well as an indication of what worked for me.

Prerequisites:

  • VSCode (tested with v1.25.1)
  • NodeJS (tested with v0.10.9)
  • NPM (tested with v6.1.0)

Run in VSCode

To get started first clone this repo:

> git clone https://github.com/jpierson/x-typescript-node-vscode

Install node package dependencies (typescript and ts-node):

> npm install

Start up VSCode if you haven't already (tested with VSCode v1.25.1):

> code .

Set a breakpoint on one of the lines such as line 5 in index.ts and start debugging by pressing the F5 key or select Debug: Start Debugging form the VSCode command pallet.
