.NET Core Tip: Boost Performance with Custom Gzip Compression Middleware

// Custom middleware to compress responses using Gzip
public class GzipCompressionMiddleware
{
    private readonly RequestDelegate _next;

    public GzipCompressionMiddleware(RequestDelegate next)
    {
        _next = next;
    }

    public async Task InvokeAsync(HttpContext context)
    {
        var originalBodyStream = context.Response.Body;

        using (var compressedStream = new MemoryStream())
        using (var gzipStream = new GZipStream(compressedStream, CompressionLevel.Fastest))
        {
            context.Response.Body = gzipStream;
            await _next(context);
            context.Response.Body = originalBodyStream;
            compressedStream.Seek(0, SeekOrigin.Begin);
            await compressedStream.CopyToAsync(originalBodyStream);
        }
    }
}

// Register the middleware in the Startup class
public void Configure(IApplicationBuilder app)
{
 app.UseMiddleware<GzipCompressionMiddleware>();

 // Other middleware registrations
 app.UseRouting();
 app.UseEndpoints(endpoints =>
 {
 endpoints.MapControllers();
 });
