I have a NodeJS project with a package.json file that contains following lines:

"scripts": {
  [...]
  "start:dev": "cross-env NODE_ENV=local supervisor --watch src -- -r '@babel/register' src/server/index.js",
  [...]
}

I can start the program in the mand line using npm run start:dev.

Now I want to debug some of the code. For this purpose I created a NodeJS Run configuration in Idea with the following parameters (pasted cross-env NODE_ENV=local supervisor --watch src -- -r '@babel/register' src/server/index.js into Node Parameters).

When I run it, I get the following error:

/usr/bin/node cross-env NODE_ENV=local supervisor --watch src -- -r '@babel/register' src/server/index.js
Debugger listening on ws://127.0.0.1:43392/5a2c1e8e-a508-4578-8eb0-2bc4f4a63b30
For help, see:

What do I need to change in order to be able to start the application in Idea and debug it?

• Do you have cross-env installed globally for the Node version IntelliJ is using? – jonrsharpe Commented Apr 22, 2020 at 15:08
• @jonrsharpe No (at least I don't remember installing it globally). – Glory to Russia Commented Apr 22, 2020 at 15:09
• Then it shouldn't be particularly surprising that doesn't work! Why not use the NPM task runner to use the existing start:dev? – jonrsharpe Commented Apr 22, 2020 at 15:10
• @jonrsharpe How exactly can I do it so that the breakpoints work in Idea? – Glory to Russia Commented Apr 22, 2020 at 15:10
• I didn't have to do anything special, just add an npm configuration, select the script I wanted and click debug. – jonrsharpe Commented Apr 22, 2020 at 15:17

Found the answer. You need to click the green arrow next to the script definition (next to the line numbers 8 and 9):

There you can select whether to run or debug the script.
