Connect
Connect is an HTTP middleware framework and routing library designed as a wrapper for the Node.js HTTP server. It serves as a middleware composition engine that allows for the creation of chains of request handlers to process HTTP traffic and manage application errors.
The framework enables the orchestration of pluggable functions to execute security, logic, and routing rules in a specific sequence. It provides the ability to match incoming request URLs to specific logic handlers based on path prefixes.
The system covers broader capabilities including centralized error handling to ensure consistent status codes and the management of security-focused HTTP headers for all outgoing responses. It also provides the tools to start and manage an HTTP server that routes network requests through a configurable pipeline.
Features
- Middleware Composition Layers - Implements a composition engine to chain pluggable functions for processing HTTP requests in a specific sequence.
- Middleware Frameworks - Acts as a framework for composing chains of request handlers and middleware to process HTTP traffic.
- Request Pipelines - Provides a linear pipeline for processing incoming traffic through pluggable modular functions.
- Middleware Layers - Provides a layered architecture for applying security and logic rules via sequential middleware.
- HTTP Request Handlers - Executes a sequence of logic handlers to manage the full HTTP request-response lifecycle.
- Middleware Chains - Orchestrates the execution of requests through a sequential chain of middleware functions.
- Middleware Orchestration - Provides a system for orchestrating the sequence of middleware that transforms web requests.
- Request Middleware - Provides pluggable middleware to intercept and filter incoming HTTP traffic.
- Request Routing - Directs incoming requests to specific handlers based on URL path prefixes.
- HTTP Routing - Provides a system for matching incoming request URLs to specific logic handlers based on path prefixes.
- Error Handling - Captures request-lifecycle errors to return standardized status codes and error documents.
- Error Handling Patterns - Implements the error-first callback pattern to propagate failures through the middleware chain.
- Application Error Handlers - Provides infrastructure to route unexpected failures to centralized error handlers.
- Middleware Callbacks - Uses a next-function callback mechanism to advance requests through the middleware stack.
- Middleware Stack Resolution - Resolves the final HTTP response by traversing the linked list of request handlers.
- Node.js Server Frameworks - Acts as a lightweight wrapper around the standard Node.js HTTP server to simplify request filtering and response handling.
- HTTP Servers - Includes tools to start and manage an HTTP server that listens for network requests.
- Node.js Frameworks and Tools - Middleware support for Node.js.
