express

Express is a widely used web framework for Node.js, designed to be fast, unopinionated, and minimalist. It provides a small but robust set of tools for building HTTP servers, making it suitable for single-page applications, websites, hybrids, and public HTTP APIs. Key features highlighted in the README include: - Robust routing - Focus on high performance - Super-high test coverage - HTTP helpers (redirection, caching, etc.) - View system supporting 14+ template engines (via @ladjs/consolidate) - Content negotiation - An executable for generating applications quickly Installation requires Node.js 18 or higher and is done through npm: ```bash npm install express ``` The fastest way to start is the express-generator executable, which scaffolds a new app: ```bash npm install -g express-generator@4 express /tmp/foo && cd /tmp/foo npm install npm start ``` The project has a clear philosophy: small, robust tooling without forcing any specific ORM or template engine. This flexibility allows developers to craft their ideal framework with over 14 template engines supported. The README also points to the official website and documentation, migration guide to v5, and community resources such as GitHub Discussions. Contribution guidelines, security policies, and the test suite setup are documented, along with the current project governance structure (Technical Committee and Triagers). Express is licensed under MIT. Example usage from the README: ```js import express from 'express' const app = express() app.get('/', (req, res) => { res.send('Hello World') }) app.listen(3000, () => { console.log('Server is running on http://localhost:3000') }) ``` This framework is one of the foundational tools in the Node.js ecosystem for building backend APIs and web applications.
