## What it is
Express is a fast, unopinionated, minimalist web framework for Node.js providing robust routing, HTTP helpers, and middleware support. It is the de facto standard server framework for building web applications and REST APIs in JavaScript.

## Use cases
- build a rest api in nodejs
- create a web server with routing
- serve html pages with template engines
- add middleware to handle requests
- build a backend for a single-page app
- handle http requests and responses in node

## When to choose
- you want a lightweight, minimal node.js server framework
- you need a huge ecosystem of middleware and community support
- you are building REST APIs or traditional server-rendered web apps
- you want a framework with extensive documentation and tutorials

## When to avoid
- you want an opinionated, batteries-included framework with structure enforced
- you need built-in TypeScript-first ergonomics or modern async patterns out of the box
- you are building GraphQL-only services where a dedicated framework fits better

## Facets
- artifact type: framework
- maturity: stable
- function: web-framework, http-server, routing, middleware, templating
- domain: web-development, backend, apis
- platform: cross-platform
- tags: http, rest-api, minimalist, server, javascript, nodejs, web-server
