Have npm watch files in background to enable integration with Visual Studio Task Runner

I am trying to have npm watch for file changes in my client side code. I can have it work from the command line ok but I'd really like it to work from Visual Studio task runner.

my package.json looks something like this:

...
"watch": {
  "compile": {
  "patterns": [
      "wwwroot"
    ],
    "extensions": "ts"
  }
},
"scripts": {
  "prebuild": "copyfiles -f ./node_modules/d3/build/*.js ./wwwroot/lib/d3",
  "compile": "tsc && browserify ./wwwroot/app/app.js -o ./wwwroot/bundle.js",
  "build": "npm run compile",
  "watch": "npm-watch"
},
...

So running npm run build then npm run watch from the command line has everything running as expected.

When I use the Task Runner however to bind my watch script to the After Build event like this:

task runner screengrab

it never 'exits' and, as such, the build never completes* and Visual Studio waits for me to kill the task before the application runs. Is there a way to have the script run in the background or some kind of 'detached' mode to enable Visual Studio to complete the build and run the application?

I tried using different watch tools but can't find any such option in any of them.

*Actually, I guess the build itself probably DOES complete but VisualStudio never runs the app and just hangs waiting on the script exiting.

Change the watch Bindings to Project Open. Then it will start watching after the project is opened.
