With Asserted you can write sophisticated uptime tests using the Socket.IO client library. Socket.IO is a library that leverages websockets and standard HTTP to enable real-time, bi-directional communication. Depending on your use case, Socket.IO is often faster to implement and less error-prone than raw websockets as it supports things like broadcast and protocol fallback out of the box.

The first is the Socket.IO logic that handles new connections and responds to messages emitted from the client.

Custom dependencies are available on paid plans, and here we’re using that option to include the Socket.IO client library in our tests.
