Running the code

We can run the preceding code as a standalone program. Name the preceding program basicHandler.go. Store it anywhere you wish to, then run it using the following command:

go run basicHandler.go

Now fire up a shell or browser to see the server in action. Here, I use the CURL request:

curl -X GET http://localhost:8000/hello

The response is:

hello, world

Go has a different concept for handling request and response. We used the io library to write to the response. For web development, we can use a template to automatically fill in the details. Go's internal URL handlers use a ServeMux multiplexer.
