This API design schema

with Service('http_service'):
    Title('This is a http service')

    with Method('liveness'):
        Description('liveness probe')
        Result(str)
        HTTP(GET, '/liveness')

from nameko.web.handlers import http


class HttpService:
    name = 'http service'

    @http('GET', '/liveness')
    def liveness(self, request) -> str:
        pass

    @http('GET', '/readiness')
    def readiness(self, request) -> str:
        pass

TODO

• Add URL parameter and type
• Add payload (name, type, description, position etc)
• Add validation
• Add gRPC server
• Generate proto files
• Generate swagger json
