How to use concurrently module for running server and client simultaneously

[igor_local]

hi everyone!
In my project i broke backend (server folder) with Express REST API on port http://localhost:3000/ and frontend (client folder) with Quasar on port http://localhost:8080/. So, i try to run both simultaneously with concurrently module.
But i have an error: ‘Unknown command “dev”’. I tried i to use ‘npm run start’ but there is no such file index.js in the client/index.js.

This is a package.json in server directory:

I used this method in Angular project before and it worked perfectly.
Please tell me the right solution. Thank you

@igor_local did you run the
npm install command before attempting to raise the application?

@patryckx
yes, sure.
Actually my question is - where is the index.js file that running the Quasar app?

Yes, i found the solution. If someone wants to use this module you need to run the script from the directory Client (where is Quasar), then it works properly
