Buzzer is a microblogging service written in Go on which users socialize by posting messages known as "buzzes". Registered users can subscribe to another users posts which appear on their "buzz-feed" along with any message in which they were mentioned (@username). Additionally, anyone can search for messages by tags (#topic).
Buzzer uses Go's channels and goroutines to coordinate the asynchronous activity and exposes the service via a WebSockets-based API for real-time, bidirectional communication with a minimal web client.
Buzzer was written solely by Taeber Rapczak using the Git ID Taeber Rapczak [email protected].
Install Go from https://golang.org/dl/.
$ make
$ ./buzzer src/client
$ open http://localhost:8080/
Alternatively, you can connect directly to the WebSocket server, using a WebSocket client such as https://github.com/hashrocket/ws.git, but the protocol would have to be inferred from the accept() function in ws.go.
$ ws ws://localhost:8080
> register user pass
> login user pass
> post Hello there!
> logout

The main components of the server are:
- kernel
- channelServer
- Message
- User
- wsClient
kernel is a implementation of Server that can only be used serially.
channelServer implements the Server interface and essentially puts a layer of
channels in front of the actual kernel to provide safe, concurrent access.
Message is a message posted by a user.
User is a person or bot that uses the service.
wsClient represents a client connected to the WebSocket server.
The client is a React.js application located in src/client/.
There are some unit tests which can be run using:
$ make test
There is also some benchmarking tests:
$ make benchmark
