# pub-sub

Example of pub-sub in Go using simple maps

## How to run

```sh

go get

go run main.go

```

then point your requests at [http://localhost:8080](http://localhost:8080)

to run the tests:

```

## API

### Publisher:

- publishing: POST /:topic_name with JSON body as a message (response 204)

### Subscriber:

- subscribing: POST /:topic_name/:subscriber_name (response 201)

- unsubscribing: DELETE /:topic_name/:subscriber_name (response 204)

- polling: GET /:topic_name/:subscriber_name (200 with JSON body as a message or 404 if no subscription found or 204 if no new messages are available)

### Message format:

```

{

	"message" : "variable content string",

	"published" : "date" // returned only for polling

}

```

## Improvements

- Make the pub-sub non-locking

- Add tests for concurrency

- Use in a demo chat application
