Feature Request: Loading content from EmbeddedResource in the assembly

[frg2089]

Do we have plans to support loading content from EmbeddedResource in the assembly?

like this https://github.com/JBildstein/SpiderEye/blob/master/Source/SpiderEye.Core/Content/EmbeddedContentProvider.cs

Hi, I've got this somewhat implemented for my purposes, so if you still need it, I could share it or make a PR (seems like I am in the contributing mood lately 😁). There is a single drawback, though. Embedded files must be flattened, meaning that all JS/CSS/images must be in the same directory as index.html. It's fine by me, but it should be somehow possible to configure it to accept any folder structure.

I'm glad you implemented this feature. Would you mind sharing it?
Normally EmbeddedResource uses . for resource names. We can change the value of LogicalName to use /.

It's super similar to the HostedContent class (and could be improved by making an abstract class or merging Hosted and Embedded classes together).

Project file (.csproj) edits:
Replace EmbeddedResource Include with your frontend dist/output folder. The only drawback is that you need to setup your frontend build process to output all files in a single directory, not nested like usual.

<ItemGroup>
	<EmbeddedResource Include="dist\**\*">
		<LogicalName>%(Filename)%(Extension)</LogicalName>
	</EmbeddedResource>
</ItemGroup>

Content Provider:

public class EmbeddedContent : IWebviewContent
{
    private readonly WebApplication _webApp;

    public EmbeddedContent(Assembly embeddedAssembly, int port = 0, bool activateLog = false, IDictionary<string, string>? additionalMimeTypes = null)
    {
        WebApplicationBuilder builder = WebApplication.CreateBuilder();
        builder.WebHost.UseKestrel(options => {
            options.Listen(IPAddress.Loopback, port);
        });

        if (!activateLog)
        {
            builder.Logging.ClearProviders();
        }

        _webApp = builder.Build();

        FileServerOptions fileServerOptions = new()
        {
            FileProvider = new EmbeddedFileProvider(embeddedAssembly, ""),
            RequestPath = "",
            EnableDirectoryBrowsing = true
        };

        if (additionalMimeTypes != null)
        {
            FileExtensionContentTypeProvider extensionProvider = new();

            foreach (var mimeType in additionalMimeTypes)
            {
                extensionProvider.Mappings.Add(mimeType);
            }

            fileServerOptions.StaticFileOptions.ContentTypeProvider = extensionProvider;
        }

        _webApp.UseFileServer(fileServerOptions);
        _webApp.Start();
    }

    public string ToWebviewUrl()
    {
        return _webApp.Urls.First();
    }
}

How to use it with Webview:

IWebviewContent content = new EmbeddedContent(typeof(Program).Assembly);
webview.Navigate(content).Run();
