Advanced Usage
For the most obvious use cases, you probably don’t need this stuff. But these are the things you might find useful when things get… interesting.
Compatible Libraries
Compatible servers or clients can be created in other languages. The implementation simply needs to read and write compatible messages using a unix domain socket. (Server implementations must also establish the socket).
The details of the message are determined by the transcoder.
Message Format: JSON Decoder
The default transcoder writes messages encoded as a JSON string. The message structure is as follows.
{
"topic": string,
"message": *
}
The message is serialized as a string terminated by a two null-byte (\0) characters. For example,
a message with the 'hello as its topic and world as its message would be put on the line as:
{"topic":"hello","message":"world"}\0\0
