the intro
An API becomes a real app when it can remember things. You connect to a database with a connection string, run queries through a driver or ORM, and return the results as JSON. The skills to learn: connecting safely, pooling connections, and never trusting raw input.
fun fact ✦
Connection pools exist because opening a database connection is expensive — reuse them.
