Using Response Compression Middleware in ASP.NET Core
This post is about using Response Compression Middleware in ASP.NET Core. Long back I wrote blog post on Enabling GZip Compression in ASP.NET5. It was a custom middleware I implemented in DNX days. Now as part of ASP.NET Core 1.1 Preview 1, Microsoft introduced Response Compression Middleware in ASP.NET Core.
To use Response Compression Middleware, first you need to add the Microsoft.AspNetCore.ResponseCompression
package to your project.json file.
"Microsoft.NETCore.App": {
"version": "1.1.0-preview1-001100-00",
"type": "platform"
},
"Microsoft.AspNetCore.Authentication.Cookies": "1.0.0",
"Microsoft.AspNetCore.Diagnostics": "1.0.0",
"Microsoft.AspNetCore.Mvc": "1.0.1",
"Microsoft.AspNetCore.ResponseCompression" : "1.0.0-preview1-final"
You can enable compression using the Configure
and ConfigureServices
methods in the Startup.cs file.
public void ConfigureServices(IServiceCollection services)
{
services.Configure<GzipCompressionProviderOptions>
(options => options.Level = CompressionLevel.Fastest);
services.AddResponseCompression(options =>
{
options.Providers.Add<GzipCompressionProvider>();
});
services.AddMvc();
}
public void Configure(IApplicationBuilder app,
IHostingEnvironment env, ILoggerFactory loggerFactory)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
app.UseResponseCompression();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
}
Now you can restore the packages using dotnet restore
command, and run the application using dotnet run
command.
You can verify GZip compression enabled or not using Chrome developer tools. You can able to see something like this.

Happy Programming :)
