What does rack/rack do?

Rack is a minimal interface that standardizes how Ruby web servers and frameworks communicate. It provides a web application interface and a web server interface, enabling Ruby applications to run across different server implementations by using a common environment hash and a standardized response tuple.

What are the main features of rack/rack?

The main features of rack/rack are: Web Environment Interfaces, Web Server Interfaces, Binary Request Stream Interfaces, Response Tuple Specifications, HTTP Request and Response Handlers, Request Interception Middleware, HTTP Middleware Pipelines, Ruby Web Server Interfaces.

Rack - standardize Ruby web server interfaces

Features

Web Environment Interfaces - Provides a standardized environment hash to decouple web servers from application logic.
Web Server Interfaces - Provides a standardized interface that decouples Ruby web servers from the frameworks they host.
Binary Request Stream Interfaces - Enables access to raw HTTP request bodies via binary-mode input streams with buffered reads.
Response Tuple Specifications - Standardizes the server response as a simple array containing a status code, response headers, and a body.
HTTP Request and Response Handlers - Provides comprehensive tools for processing raw request streams and managing HTTP response delivery.
Request Interception Middleware - Implements a modular middleware pipeline to intercept and modify requests and responses.
HTTP Middleware Pipelines - Implements a modular pipeline of callable objects to intercept and modify HTTP requests and responses.
Ruby Web Server Interfaces - Standardizes how Ruby web servers and frameworks communicate via a common environment hash and response tuple.
Web Application Interfaces - Provides a specification that enables Ruby applications to run across different server implementations without modification.
Session Data Stores - Provides a standardized hash-like interface for storing and retrieving persistent user data across requests.
Response Body Streaming - Implements incremental response body delivery using a callable object that responds to each.
Response Body Callbacks - Handles two-way server-client communication by passing a callback as the response body.
Connection Hijacking - Allows taking direct control of raw TCP connections to bypass standard request-response cycles.
TCP Connection Hijacking - Allows direct control of raw TCP connections to bypass standard request-response cycles.
Application Instance Routing - Maps specific URL paths to different application instances within a single process.
Application Environment Mocking - Includes utilities to simulate the server environment and response tuples for application testing.
API Request Mocking - Simulates requests and responses in a testing environment to verify application behavior.
HTTP Traffic Simulation - Includes utilities to simulate HTTP requests and responses for testing application behavior.
Incremental Response Streaming - Provides the ability to stream HTTP response bodies incrementally to the client.
Multipart Form Parsing - Parses multipart/form-data requests to extract uploaded files and form fields.
Protocol Upgrades - Enables signaling the web server to upgrade the protocol via environment headers.
Filesystem Static File Servings - Delivers static files and directory indexes from the local filesystem to the client.
Static File Servers - Includes a built-in implementation for serving static files and directory indexes from the filesystem.
