Package examples/helloworld

The helloworld.example microservice demonstrates the classic minimalist example.

http://localhost:8080/helloworld.example/hello-world simply prints Hello, World!.

The code looks rather daunting but practically all of it is code generated. The manually-coded pieces are:

The definition of the service and its single endpoint HelloWorld in service.yaml:

general:
  host: helloworld.example
  description: The HelloWorld microservice demonstrates the classic minimalist example.

webs:
  - signature: HelloWorld()
    description: HelloWorld prints the classic greeting.

The implementation of the HelloWorld endpoint in service.go:

w.Write([]byte("Hello, World!"))
return nil

A test of TestHelloworld_HelloWorld in integration_test.go:

ctx := Context()
HelloWorld_Get(t, ctx, "").BodyContains("Hello, World!")

And finally, the addition of the microservce to the app in main/main.go.

app.Add(
	helloworld.NewService(),
)
