Binary messages and compression example

This example shows how to send binary messages and how to add compression.

Requirements

• The clients can run in either the browser or in Node.js.
• The server must run in a Node.js environment.
• NPM or other package manager to install kalm, @kalm/ws and the compression library of your choice. In this example, we are using snappy.

Testing

Launch the server first:

node ./server.js

It should log that the server is ready to receive new connections. At this stage, launch any number of clients:

node ./client.js

The clients should connect to the server and send an "hello world!" message.

In turn, the server will both respond to that client: "hello from the server!" and broadcast to all clients "A new client has connected!"
