Building a Scalable REST API with NodeJS

In this tutorial, we’ll guide you through building a scalable and production-ready REST API for an ecommerce app using some of the most popular tools in the NodeJS ecosystem, including TypeScript, Express, Drizzle ORM, Postgres, and Genezio. This project is perfect for beginners and those looking to level up their backend development skills.

You’ll start by setting up a new NodeJS project, configure it with TypeScript, and build a fully functional REST API for managing products and orders. Throughout this process, you'll gain valuable experience working with authentication, request validation, error handling, and database management, all while keeping things strictly typed for a safer, cleaner codebase.

What You'll Learn

• NodeJS & TypeScript: Learn to set up a scalable NodeJS project with strict typing.
• Express: Manage API routes, controllers, and middleware to handle CRUD operations.
• Drizzle ORM & Postgres: Use Drizzle ORM to interact seamlessly with a Postgres database and handle migrations.
• Request Validation & Error Handling: Implement smooth validation using Zod and create efficient error-handling strategies.
• Genezio: Deploy your API to a serverless infrastructure and eliminate cold start issues for optimal performance.

Multiple Parts of This Mega Tutorial

This tutorial is just the first step! In the upcoming videos, we’ll expand the project:

1. Build the Backend: Today’s focus is on building a RESTful API for the backend using NodeJS, Express, and Postgres.
2. Mobile App Integration: Next, we’ll create a mobile ecommerce application using React Native and Expo, integrating it with the backend API we built today.
3. Admin Dashboard: Finally, we’ll develop a Next.js dashboard where admins can manage products, orders, and more.
