net/http is Go's standard-library package providing HTTP client and server implementations.
- How it is used
- Uses net/http to fetch exchange rates for a CLI and serve requests for a web service.
- How deep it goes
- Works through client timeouts, server startup, routing, handlers, status codes, and tests without detailing HTTP transport internals.
- Examples
- Uses an exchange-rate endpoint, a delayed test server, and a game-creation endpoint exercised with curl.
- What you can do after
- Build it from scratch: make a time-bounded HTTP call or serve and test a routed endpoint with net/http.

Go in Practice, Second Edition
net/http is Go's standard library package for HTTP clients and servers.
- How it is used
- Provides standard-library HTTP clients and servers, from simple requests and handlers to extensible web applications.
- How deep it goes
- Works through runnable GET and server examples, then describes request/client separation and configurable clients; server construction extends into routing and middleware.
- Examples
- Uses a localhost web server, a GET that reads a response body, a DELETE through the default client, and a timed custom client.
- What you can do after
- Build it from scratch as a small Go web server, and make GET or custom-client HTTP requests.

Go by Example
The http package is Go's standard-library package providing HTTP client and server implementations and related types.
- How it is used
- Uses standard-library HTTP clients and servers to build responsive programs, services, request handlers, and tests.
- How deep it goes
- Explains client round trips and server handlers through APIs, execution flow, connection pooling, and response-writing order.
- Examples
- Uses concurrent request pipelines, NewRequest, NewRequestWithContext, Client.Do, status checks, handlers, and ResponseWriter.
- What you can do after
- Build it from scratch by sending HTTP requests, consuming responses, registering handlers, and serving clients.
