[Blazor] Client side : enable Brotli compression

[RemiBou]

Is your feature request related to a problem? Please describe.

When enabling brotli compression, you can decrease mscorlib.dll from 1,4MB to 647Kb (-54%) and System.Core from 310Kb to 145Kb. This kind of improvement can be seen on many other dll. Given the fact that load time is very important for client side app, this seems like an easy win.

Describe the solution you'd like

Maybe when calling MapFallbackToClientSideBlazor setup brotli and enable compression on "application/octet-stream"

Additional context

On my project Toss the first load went from 4,7MB to 2,7MB.

Thanks for contacting us, @RemiBou.
@Tratcher is there anything we need to do here, or is the compression enabled by default?

[Tratcher]

The blazor template doesn't include the response compression middleware by default.

Brotli support was added back in 2.2 (aspnet/BasicMiddleware#217), and we added application/wasm to the compression list (2d3ad1c).

How is mscorlib.dll being served? Dll's aren't on static file's default list.

application/octet-stream isn't on the default compression list.

That's the server template - the relevant stuff for client is here:

• https://github.com/aspnet/AspNetCore/blob/master/src/Components/Blazor/Templates/src/content/BlazorWasm-CSharp/Server/Startup.cs
• https://github.com/aspnet/AspNetCore/blob/master/src/Components/Blazor/Server/src/Builder/BlazorHostingApplicationBuilderExtensions.cs#L72

Ok, that should be everything you need.

@RemiBou you should already be seeing dynamic compression here.

Yes indeed you got it covered already ! Thanks for your time, sorry for the issue. Le ven. 9 août 2019 21:42, Chris Ross <[email protected]> a écrit :
