Auto reload blazorise.com

[damianog]

Some times I find blazorise.com page in reaload state

In similar situation I've implemented healthcheck and the script:

<script src="_framework/blazor.server.js" autostart="false"></script>
<script>
Blazor.start({
    reconnectionHandler: {
        onConnectionDown: (options, error) => {
            var isReloading = false;

            async function attemptReload() {

                if (!isReloading) {
                    isReloading = true;
                    var request = new Request({
                        url: '/healthcheck',
                        method: 'GET'
                    });
                    var result = await fetch(request);

                    if (result.status == 200) {
                        document.location.reload();
                    }
                    isReloading = false;
                }
            }
            setInterval(attemptReload, 1500);
        },
        onConnectionUp: () => console.log("Reconnected!")
    }
});
</script>

Thanks for the script. We will try and see if it helps us :)

Like this?

using Microsoft.AspNetCore.Mvc;

namespace Blazorise.Docs.Server.Controllers;

[Route( "healthcheck" )]
[ApiController]
public class HealthcheckController : ControllerBase
{
    [HttpGet]
    public IActionResult Get()
    {
        return new OkResult();
    }
}

I just used

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddHealthChecks();

var app = builder.Build();

app.MapHealthChecks("/healthcheck");

I just used

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddHealthChecks();

var app = builder.Build();

app.MapHealthChecks("/healthcheck");

Nice. Thank you!

Hello,
I don't think it's unnatural to go into reload, this happens when the circuit is broken, which sometimes happens when you leave a Blazor.Server tab open idly for some time.

What's the health check for here? Is that not redudant? I have some app at work with reload and I personally just try to reload each time.

The circuit could broke due server update or by browser or network standby, think about mobile device.
The healthcheck is only a basic point of start, if it give a response you may assume the site is UP, but you could implement a more detailed response with services state to check and force the reload only if needed.
