Module Overview

What You’ll Learn

• Combine authentication, authorization, validation, and hardening into one API
• Build a real automated test suite covering that entire API
• Recognize the complete difference between this API and where this course started

💡 Why this matters: Every module in this course built one piece, hashing, sessions, JWTs, roles, validation, rate limiting, testing, logging. This module is where every piece comes together in a single, coherent, production-ready application.

What’s Covered

• Assembling the full stack, registration, login, role-gated routes, validated input, rate limiting, and logging, in one Express app.
• A complete test suite, unit tests (Module 7) and integration tests (Module 8) covering the whole API.
• A last security pass, confirming every route is protected, validated, and rate-limited exactly as intended.

Hands-On

By the end of this module, you’ll have a complete, authenticated, authorized, validated, hardened, and tested REST API, and a passing test suite proving it.

This is the final module of Authentication, Security & Testing for Node.js. From here, the next course in this track picks up scaling and deployment, taking a production-ready application and actually shipping it.
