RSocket is a binary protocol for use on byte stream transports such as TCP, WebSockets, and Aeron.

It enables the following symmetric interaction models via async message passing over a single connection:

• request/response (stream of 1)
• request/stream (finite stream of many)
• fire-and-forget (no response)
• event subscription (infinite stream of many)

Releases are available via Maven Central.

Example:

dependencies {
    implementation 'io.rsocket:rsocket-core:0.11.5'
    implementation 'io.rsocket:rsocket-transport-netty:0.11.5'
}

Install the google-java-format in Intellij, from Plugins preferences. Enable under Preferences -> Other Settings -> google-java-format Settings

Format automatically with

$./gradlew goJF

Frames can be printed out to help debugging. Set the logger io.rsocket.FrameLogger to debug to print the frames.
