Vite server is not started

[asbjornu]

I have the following lines of code in my Program.cs:

builder.Services.AddViteServices();

// …

if (app.Environment.IsDevelopment())
{
    app.UseWebSockets();
    app.UseViteDevelopmentServer(true);
}

When starting the application, I get the following logged to the console:

warn: Vite.AspNetCore.ViteDevServerMiddleware[10]
      Connection refused (localhost:5173). Make sure the Vite development server is running
warn: Microsoft.AspNetCore.HttpsPolicy.HttpsRedirectionMiddleware[3]
      Failed to determine the https port for redirect.
info: Vite.AspNetCore.ViteManifest[1]
      The manifest file won't be read because the vite development service is enabled. The service will always return null chunks

From this, my understanding is that npx vite (or something similar) should be called somewhere, somehow, to launch the Vite development server. That, unfortunately, does not seem to happen. If I execute npx vite manually in the terminal, everything seems to start working, but my understanding was that Vite.AspNetCore was going to take care of that for me?

If it is by design that Vite needs to be started manually, I think it needs to be documented. If it is supposed to be started automatically, I'm in need of assistance, because it isn't happening. 🙏🏼

Hi @asbjornu. Did you set the Server.AutoRun setting to true?
You can see the list of options here.
Pass that option to the AddViteServices function, an user secret or you appsettings files.

Thanks! I now added this:

builder.Services.AddViteServices(options =>
{
    options.Server.AutoRun = true;
});

…but I still have to manually start Vite on the command line for things to start working.

Do you have your package.json in a subfolder instead of the project root? If that's the case, then set the Server:PackageDirectory option too.

[asbjornu]

package.json is in the same folder as the .csproj:

Which OS and package version are you using?

[asbjornu]

macOS Ventura 13.6.7, package version 2.1.0.

I'm also experiencing that scripts with the vite-src attribute are completely removed from the published Razor views. What am I doing wrong here?

Do you have a reproduction repo?
