Express
Express is a minimalist Node.js web application framework for building HTTP servers, routing requests, handling responses, and composing middleware.
Bootstrapping Microservices, Second Edition: With Docker, Kubernetes, GitHub Actions, and Terraform
Express is a Node.js web application framework for building HTTP servers and request-handling routes.
- How it is used
- Builds Node.js HTTP servers and request-handling routes for small microservices.
- How deep it goes
- Explains installation, minimal routing, responses, and listening, then stops short of broader framework features.
- Examples
- Uses a Hello World server and a browser-playable video endpoint at /video.
- What you can do after
- Build a working Express HTTP server and extend it with request routes such as a video-streaming endpoint.
Building User-Friendly DSLs
A Node.js web application framework for building HTTP servers and routing web requests.
- How it is used
- Builds a minimal REST backend that persists and serves JSON while hosting frontend static content.
- How deep it goes
- Explains installation, application creation, routing, JSON responses, startup, and static serving, but leaves PUT handling as future work.
- Examples
- Uses contents.json, a rental AST, GET /contents, port 8080, and static serving of the dist/ directory.
- What you can do after
- Build it from scratch as a Node.js server that returns JSON and serves a frontend.
Road to Kubernetes
Express.js is a minimal Node.js web application framework for building server-side applications and APIs.
- How it is used
- Builds server-side web applications and microservices that handle HTTP request-response cycles.
- How deep it goes
- Explains project setup, routing, startup, ports, HTML, and JSON responses, while deferring broader Express.js treatment.
- Examples
- Demonstrates a Hello World route, configurable ports, HTML output, and a JSON API route.
- What you can do after
- Builds a runnable Express application that serves HTML and JSON on configurable local ports.
Amazon Web Services in Action, Third Edition: An in-depth guide to AWS
Express is a Node.js web application framework for routing HTTP requests and composing middleware.
- How it is used
- Provides HTTP routing and middleware composition for a Node.js REST API.
- How deep it goes
- Demonstrates initialization, middleware, route handlers, and responses, but deliberately avoids explaining Express internals in depth.
- Examples
- Uses image-process creation, state lookup, and image-upload routes as concrete Express examples.
- What you can do after
- Build a Node.js REST API with Express routes, JSON middleware, AWS-backed persistence, uploads, and a listening server.
