Azure pipeline is failing when we use ng serve or npm run start

Question

I am trying to build a azure pipeline for a nodejs project. While deploying the application via release pipeline to azure web app, if I use "npx serve -s" it is working but if I use "npm run start"/"node server.js"/"ng serve" it is not working. Can someone explain what is the issue?

Answer 1

I think when you start with your project, it will like run something like below in pipline.

- task: AzureRmWebAppDeployment@4
  displayName: deploy
  inputs: 
   azureSubscription: 'yoursubscription'
   appType: webAppLinux
   webappName: 'angularproj'
   deployToSlotOrASE: true
   ResourceGroupName: mygroup
   packageForLinux: dist/myangularapp

   StartupCommand: 'npx serve -s'
