concurrently VS BrunoLau.SpaServices

In our demonstration, we use Webpack to build apps and Babel to transpile React code to plain JavaScript. We run our server with Express.js and use concurrently to run multiple commands concurrently. The tool nodemon helps develop node.js-based applications by automatically restarting the node application when file changes in the directory are detected.

It seems like you're trying to solve a developer experience, or DX, problem. I believe the "norm" is to have these scripts run separately, e.g., run npm start and dotnet watch in separate terminals. However, if you want to make it so you don't have to do that, which is fine everyone develops differently, then you could look into concurrently. Then you could add a script to the frontend's package.json like npm start to run concurrently "webpack serve" "dotnet watch".

I’m no pro at this, but if I remember correctly, you want to build a separate server and client folder and then set up a proxy and use https://www.npmjs.com/package/concurrently

To run both commands, will use the concurrently npm package:

If you aren't using React or Angular you probably want to take a look at this project, which includes more generic webpack support that Microsoft dropped after Asp.Net Core 2: https://github.com/brunolau/BrunoLau.SpaServices
