Build a Production-Structured REST API with Express (Final Project) | Web Dev Series #017

This is it — the final video of the Node.js & Express series! Over the last four videos we built Node.js fundamentals, an Express server, full CRUD with Postman testing, and a connected React frontend. Today we bring it all together into one complete, properly structured REST API: a Task Manager, built with the same architecture you'll find in real production codebases. 📌 What you'll learn in this video: Planning a resource's fields and routes before writing code Structuring an Express project with controllers, middleware, and routes folders Environment variables on the backend with dotenv Writing reusable custom validation middleware Centralized error handling with Express's 4-argument error middleware A 404 catch-all handler for unmatched routes Assembling and fully testing a complete Task Manager REST API 🎯 Interview topics covered in this video: Planning an API's fields and routes before coding Separating routes from controllers dotenv and environment variables on the backend Writing and applying custom validation middleware Express's 4-argument error-handling middleware and next(err) 404 catch-all handlers 💬 Got stuck anywhere? Drop your question in the comments — I reply to every one. 👍 If this series helped you, a like, subscribe, and a comment with what you built genuinely helps the channel reach more freshers preparing for placements. #Express #NodeJS #RESTAPI #WebDevelopment #BackendDevelopment #FullStackDevelopment #LearnToCode #TechIndia
