A guide to the best resources to learn Express.js for free in 2023.

There’s a framework for everything these days, and not just on the frontend.

When it comes to the backend and full-stack JavaScript development, Express.js (or simply Express) is a popular choice.

With its minimalist design, Express simplifies key web development tasks like routing, middleware, and request/response handling for Node.js applications.

Learning Express allows you to use Node.js across the full stack, from frontend to backend. By utilising a unified language across client and server, Express streamlines full-stack web development workflows.

This guide will provide an overview of Express and its core capabilities.

And will point you to great free resources to master this lightweight framework and see how its simplicity can accelerate building web apps and APIs.

Why Learn Express.js?

Learning Express opens up the full potential of Node.js for web development. Here are some of the key benefits:

• Streamlined routing system for building APIs and web apps
• Easy middleware integration for extended functionality
• Template engines support for rendering dynamic web pages
• A flexible approach that fits many project needs and coding styles
• Full-stack JavaScript simplifies development with front-end and back-end in one language
• Large ecosystem of middleware modules to tap into
• Popular in the industry and key for Node.js jobs

Key Features of Express

Now we’ve seen the benefits of Express, let’s take a brief look into some of those great key features it has for rapid web development:

Flexible Routing

Easily define routes and endpoints for APIs, pages, error handling and more. Use handy path params, route matching, and chained route handlers.

Built-In Middleware

Use Express middleware for request parsing, static file handling, error catching, and more. Third-party middleware is also simple to integrate.

Template Engine Integration

Configure and render templates like EJS, Pug, Mustache to generate HTML views. Shared templates and layouts keep things DRY.

Handy Utilities

Express includes utils like res.redirect() and req.get() that simplify common tasks when working with HTTP requests and responses.

With these capabilities, Express makes it enjoyable to build Node.js apps quickly.
