How to configure multiple virtual applications in Azure App Service?

I’m creating an API using Express and trying to deploy on Azure App Service. I’ve managed to deployed and run it successfully on the default path sitewwwroot.

It works fine but I want to deploy it on a different path sitebackend. So I’ve setup the path mapping for it and deployed the exact same code and it gives out an error.

I’ve deletes the code in the sitewwwroot, thinking it may be because of the web.config duplication and same result. I also restarted the App Service and still not working.

Any idea how to solve this issue?

    I am able to deploy multiple Apps under Site folder in Azure App Service.
    Please follow the below steps.

    • In Azure Portal create an App Service with the Runtime stack Node.

    • By default virtual path with / with Physical path sitewwwroot will be created.

    • In VS, Create 2 New Express App and Name it as Exp1 and Exp2.

    • In Azure Portal, add new Virtual Directories with name Exp1 and Exp2.
      enter image description here

    • Make sure the App name and the Virtual path name are same.

    • In Azure App Service => Overview, you will find an option to download Publish Profile (Get publish profile).
      enter image description here

    • In VS, Right Click on the Project folder (Exp1) which you want to Deploy and select Import Profile . In Browse option select the downloaded Publish Profile and Continue the next steps.
      enter image description here

    In Publish Connection settings, change the Sitename as below Save and Publish.
    enter image description here

    Repeat the same steps with App 2 (Exp2).
    You can see the Folders Exp1 and Exp2 with source files are created and wwwroot folder exists as well.
    enter image description here

    why would you configure multiple virtual machines in Azure while you can create a blueprint or a function and use it, something that looks like horizontal scaling configure once build many.

    hope this helps 🙂
