Node.js Study Plan

Your brief

Start with a pure domain function and boundary tests. Add modules and package scripts, then asynchronous resources with explicit cleanup. Build HTTP only after its input and error policies are clear. Choose one actual database workflow, inspect its rejection cases and transaction or document boundary, then add operational readiness and shutdown. Introduce workers or realtime protocols only when the workload and product need them.

Run the code

Run this example locally with Node.js. The exact sources are reviewed on Node 22.15.1 and Node 24.22.1 unless a specialised lab states otherwise. Save the complete source as study-plan.mjs in a separate empty exercises folder and run node study-plan.mjs. There is no Node.js browser runner on Bhylu; the plain JavaScript playground does not provide these filesystem, server or process APIs.

Download the complete source. Ordinary Node scripts need no Apache, PHP or MySQL service. File examples own their temporary folders; network fixtures use loopback and available temporary ports.

Worked solution

const plan = [
  ['domain', 'boundary tests'],
  ['transport', 'status and body limits'],
  ['storage', 'identity and atomic changes'],
  ['operations', 'readiness and shutdown'],
];
console.log(plan.map(([stage]) => stage).join(' -> '));
console.log(plan[2][1]);

domain -> transport -> storage -> operations
identity and atomic changes

Extend and test

Deliver the equipment-desk project, its passing tests and a short report explaining in-memory limits, credentials, database choices and the next production work required.
