How to create a unique URL for each PR?

Unlike Vercel, it is not possible to get a unique URL for each pull request in Azure Web Apps.

You have two options to get the unique URLs for each PR.

1. Create new web apps dynamically for each PR.
2. Creating a new deployment slot for each PR.

Since creating a new web app each time is not effective, it’s better to use deployment slots.

• You can switch with the main slot easily with below command

az webapp deployment slot swap --name <app_name> --resource-group <resource_group> --slot <slot_name> --target-slot <target_slot_name>

You can create deployment slot via below command via Azure CLI

az webapp deployment slot create --name <app_name> --resource-group <resource_group> --slot <slot_name>

• Please refer this docfor better understanding about deployment slots in DevOps pipeline.

Here you'll get a unique URL for each deployment slot.
