Build shows empty screen

[tusharsinghal1610]

everything was fine , and i managed to generate the build also.
But the problem is , if i directly run the application ,it shows empty screen
but when i run "npm run dev" command in command window and then if i start the same application ,i get the desired output.
what i want is , application should run without typing "npm run command " in command window as it is not user friendly method. it should just start by clicking on application icon.
please answer fast
