Demo

package main

// Import package
import "github.com/kataras/iris/v12"

func main() {
  // Define iris instance
  app := iris.New()
  // Use gzip compression middleware
  app.Use(iris.Compression)

  // Router setup
  app.Get("/", func(ctx iris.Context) {
    ctx.HTML("Hello <strong>%s</strong>!", "World")
  })

  // Listen on port
  app.Listen(":8080")
}

Performance Testing

Send 200,000 requests with dynamic parameters as integers, sending JSON as the request body, and receiving JSON as the response.
