Socket.IO topics
12 short topics in APIs and Integration. Each one is a single focused exercise with a clear piece of evidence at the end.
12 topics, one exercise each.
Work through them in order, or jump to the one you need.
These are draft topic outlines (draft; instructor review pending). Full lessons follow after review; ask Ajay if you need a topic sooner.

Connection and session lifecycle
Demonstrate connection and session lifecycle in a focused Socket.IO example; verify normal behavior and one edge or failure case. Keep the exercise bounded and record the behavior supported by the chosen version.
Open micro-course → - 02
Message framing and representation
Demonstrate message framing and representation in a focused Socket.IO example; verify normal behavior and one edge or failure case. Keep the exercise bounded and record the behavior supported by the chosen version.
Open micro-course → - 03
Client and server event contracts
Demonstrate client and server event contracts in a focused Socket.IO example; verify normal behavior and one edge or failure case. Keep the exercise bounded and record the behavior supported by the chosen version.

Learn the same ideas beyond Socket.IO.
These courses share topics with this one, so you can compare how each language or tool handles the same concept.

You have the curiosity.
Let’s turn it into capability.
