Web front-end example

This example demonstrates an HTTP front-end, using gin, which connects to the backend Twitter server via grpc.

$ go run frontend/main.go
[GIN-debug] GET   /tweets/:user_id          --> main.func·001 (3 handlers)
[GIN-debug] Listening and serving HTTP on :8080

Now, let's do some twittering!

$ curl -v -d '{"text": "a tweet!", "userId": 1}' -H "Content-Type: application/json" -XPOST http://localhost:8080/tweet/1
[...]
< HTTP/1.1 204 No Content

$ curl http://localhost:8080/tweets/1
[{"text":"a tweet!","user":{"ID":1}}]
