Basic-Date-Service

Made a basic date service with go-kit-CLI using gorilla mux router to get the current date, status of the service and validate a date.

Running

1. Download the project in your GOPATH.
2. cd inside the folder and run docker-compose up using the docker-compose.yml file or using go run hello/cmd/main.go

Architechture

hello/  
|---cmd/  
|------service/  
|----------server.go          Wire the service.  
|----------server_gen.go      Also wire the service.  
|------main.go                Runs the service  
|---pkg/  
|------endpoints/  
|----------endpoint.go        The endpoint logic along with structures for request and reponse.  
|----------endpoint_gen.go    This will wire the endpoints.  
|----------middleware.go      Endpoint middleware  
|------http/  
|----------handler.go         Transport logic encode/decode data and gorilla mux request reponse routing of the service.  
|----------handler_gen.go     This will wire the transport.  
|------io/  
|----------io.go              The input output structs.  
|------service/  
|----------middleware.go      The service middleware.  
|----------service.go         Business logic.  

Reproducing the service

1. Use kit new service hello to make a service named hello.
2. Edit the business logic file (hello/pkg/service/service.go) with the methods in your service interface.
3. To generate the service with gorilla and default middleware use kit g s hello -w --gorilla
4. A basic service that does not handle request and reponse can be run right now using go run hello/cmd/main.go
5. NOTE: Our service runs at port 8081 and not on the default gorilla mux port 8080.
6. Now implement our services in hello/pkg/service/service.go file.
7. One can write the test in the same service folder for the business logic, right now.
8. Then edit hello/pkg/endpoint/endpoint.go for the request reponse structs.
9. Then edit hello/pkg/http/handler.go for the encode and decode.
10. Edit the requests routed by the gorilla mux router in hello/pkg/http/handler.go
11. Correct any errors if they arise.
12. Make a dockerfile using kit g d
13. We are done just run the service using docker-compose up
