Creating your first Nameko microservice

Let's start by creating a new folder titled temp_messenger and placing a new file inside, named service.py, with the following code:

from nameko.rpc import rpc 
 
class KonnichiwaService: 
 
    name = 'konnichiwa_service' 
 
    @rpc 
    def konnichiwa(self): 
        return 'Konnichiwa!' 

We first start by importing rpc from nameko.rpc. This will allow us to decorate our methods with the rpc decorator and expose them as entrypoints into our service. An entrypoint is any method in a Nameko service that acts as a gateway into our service.

In order to create a Nameko service, we simply create a new class, KonnichiwaService, and assign it a name attribute. The name attribute gives it a namespace; this will be used later when we attempt to make a remote call to the service.

We've written a method on our service which simply returns the word Konnichiwa!. Notice how this method is decorated with rpc. The konnichiwa method is now going to be exposed via RPC...
