[Free] Express.js Fundamentals: Build Rest Apis And Dynamic Web App
Build REST APIs, Master Middleware, Routing, Express Router, Error Handling, and Backend Fundamentals
Requirements
- Basic JavaScript knowledge is recommended. Familiarity with Node.js fundamentals will help, but no prior Express.js experience is required.
Description
Express.js is one of the most widely used frameworks for building web applications and REST APIs with Node.js. In this course, you’ll learn how Express works from the ground up by building real server-side applications while understanding the concepts behind every feature.
Instead of simply copying code, you’ll develop a solid understanding of how Express handles requests, middleware, routing, and application structure so you can confidently build your own backend applications.
Throughout the course, you’ll progressively build an Express application while learning industry-standard development practices that can be applied to larger projects.
