Web demo scenario

This example implements a simple application that starts two child processes - webServer and timeServer.

webNode (node.Node) main.go  -> webApp (gen.Application) app.go
                         |
                          -> webServer (gen.Web) web.go
                         |       |
                         |        ->> url '/' handler (gen.WebHandler) web_root_handler.go
                         |        ->> url '/time/' handler (gen.WebHandler) web_time_handler.go
                         |
                          -> timeServer (gen.Server) time.go

webServer implements gen.Web behavior and defines options for the HTTP server and HTTP handlers with two endpoints:

  • / - simple response with "Hello"
  • /time/ - demonstrates async handling HTTP requests using timeServer

By default, it starts HTTP server on port 8080 so you can check it using your web-browser http://localhost:8080/ or http://localhost:8080/time/.

You may also want to benchmark this example on your hardware using the popular tool wrk. Here is the result of benchmarking on the AMD Ryzen Threadripper 3970X (64) @ 3.700GHz:
