Can I add a debug script to NPM?

Question

I have edited my package.json to customize the \"start\" script so it adds the --debug flag to node:

  \"scripts\": {
    \"start\": \"node --debug server.js         


        

Answer 1

From the nodejs docs:

The legacy debugger has been deprecated as of Node 7.7.0. Please use --inspect and Inspector instead.

So starting from Node 7.7.0v use --inspect

Answer 2

VS Code adds a debug button inline in the package.json file

1. Open package.json and click debug above scripts section

2. Select script to debug

3. Debugger should be attached

Answer 3

In your package.json define the script

"scripts": {
  "debug": "node --inspect server.js"
}

And then you can use npm's run-script

npm run-script debug

or the shorter version

npm run debug
