Deploy Blazor App on Ubuntu

created 5 years ago

Hi!

I'm testing the new XAF Blazor with a simple App. It has only one BO, for simplification. Locally it run connected to a MySQL database (I tried both in Windows + VS2019 and in Mac OS + VS for Mac). Everything OK with that.

Now I'm trying to deploy it to DO in Ubuntu environment. I have followed MS instructions to configure nginx as a reverse proxy for kestrel.

When I hit the server the App try to load but fail with this output in the console:

Hello Aldo,

We have not deployed XAF Blazor Server apps to this environment, but according to "Unhandled exception rendering component: Could not find 'xaf' in 'window'." and other symptoms, important files are missing on your server. Please make sure that your published app has the following file: wwwroot_content\DevExpress.ExpressApp.Blazor\scripts.js

For more information, see https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/blazor/server?view=aspnetcore-3.1.

      Hi Dennis!

      Yes, actually it was my fault! Now everything works as expected!

      Thank you!

        Cool, thanks for sharing your experience with the XAF community!
