Forcing reload of Blazor client after publishing changes

If anyone looks solution for Azure Pipelines and Azure Static Web App deployment, here is what worked for me:

  1. Added following line on top of service-worker.published.js file.


  1. Added Bash step to *.yaml file, just change your app location accordingly.
  - master

  vmImage: ubuntu-latest

  - checkout: self
    submodules: true
  - bash: 'sed -i ''s/{#CACHE_VERSION#}/$(Build.BuildId)/'' MathApp/wwwroot/service-worker.published.js'
  - task: AzureStaticWebApp@0
      app_location: 'MathApp'
      output_location: 'wwwroot'
      azure_static_web_apps_api_token: $(deployment_token)

if you are working on dot net core3.X PWA app, you can add comment in service-worker.published.js so that when browser will compare its cached service worker with updated one, browser will track the changes and load new one.

Since your app is a PWA, you can declare a js file for registration in the navigator.serviceWorker object. This my.js file can contain a const CACHE_VERSION = 1.0. Updating this value should force the client to download the latest files. See Jeremy Likness' blog post for more info.
