Express

Minimal and flexible Node.js web framework

Features

  • Minimalist routing and middleware architecture
  • Massive middleware ecosystem
  • Template engine support (EJS, Pug, Handlebars)
  • HTTP utility methods and content negotiation

Pros

  • Industry standard with the largest middleware ecosystem
  • Extremely well documented with abundant learning resources
  • Simple mental model — request in, response out

Cons

  • No built-in TypeScript support or schema validation
  • Callback-based error handling can be clunky
  • Performance lags behind newer frameworks like Fastify and Hono

Overview

Express is the most widely used Node.js web framework, providing a thin layer of fundamental web application features on top of Node.js. Its minimalist approach gives developers full control over how they structure their applications, with a simple middleware pipeline as the core abstraction.

Created in 2010, Express has become the de facto standard for Node.js web development. Nearly every Node.js tutorial, course, and boilerplate starts with Express, making it the most familiar framework in the ecosystem. While newer alternatives offer better performance and developer experience, Express remains dominant in production.

When to Use

Express is the right choice when you need maximum compatibility with existing middleware and libraries, when your team is already familiar with it, or when following tutorials and guides that assume Express. For new projects, consider Fastify or Hono for better performance and TypeScript support.

Getting Started

npm init -y && npm install express
import express from "express";

const app = express();

app.get("/", (req, res) => {
  res.json({ message: "Hello from Express" });
});

app.listen(3000);
