chimurai/http-proxy-middleware

Features

• HTTP Request Forwarders - Forwards incoming HTTP requests to target backend servers while maintaining headers and body content.
• HTTP Reverse Proxies - Provides a central entry point for Node.js applications to route incoming network traffic to backend microservices.
• API Gateways - Consolidates multiple backend services behind a single interface to manage traffic distribution and request path rewriting.
• Connection Forwarders - Manages persistent bidirectional WebSocket communication by routing protocol upgrade handshakes to backend servers.
• WebSocket Protocol Upgrades - Manages HTTP upgrade handshakes to transparently forward persistent WebSocket connections to backend servers.
• Request Filters - Uses path patterns and glob matching to determine which incoming requests are forwarded to the target.
• HTTP Request Routing - Implements a routing engine to direct network requests to different target servers using path patterns and glob matching.
• Request Routing - Directs network requests to target servers at runtime using path matching and asynchronous logic.
• Node.js Proxy Servers - Implements a Node.js-based proxy server for routing HTTP and WebSocket traffic with customizable transformations.
• Traffic Routing - Directs network requests to multiple backend targets based on path patterns, glob matching, or custom logic.
• WebSocket and Protocol Proxying - Handles protocol upgrade handshakes to maintain persistent bidirectional WebSocket communication between clients and servers.
• Request and Response Transformers - Provides a configurable layer to inject, remove, or rewrite request and response headers and bodies during transit.
• Dynamic Target Selection - Determines the target backend server at runtime by evaluating incoming request paths against patterns or asynchronous logic.
• WebSocket Traffic Routers - Manages persistent bidirectional communication by forwarding real-time WebSocket upgrade handshakes and data streams.
• Request Interception Middleware - Integrates into the server request pipeline to intercept and modify network traffic before it reaches the backend.
• Request Path Rewriters - Transforms outgoing request URLs and incoming redirect headers using regular expressions to align environment paths.
• HTTP Stream Piping - Routes incoming network data directly to target servers using streams to maintain low memory usage.
• Header Rewriters - Intercepts and modifies response headers to change location hostnames, protocols, or cookie domains.
• Proxy Configurations - Provides adjustable settings for SSL verification, timeout thresholds, and header manipulation.
• Proxy Scripting Extensions - Offers a plugin system and event subscription mechanism for adding custom logic to the proxy pipeline.
• Request Header Configuration - Injects or updates HTTP request headers on outgoing calls to ensure correct routing and connectivity.
• Cookie and Redirect Rewriting - Adjusts domain and path settings within set-cookie headers to maintain routing consistency in proxied environments.
• Proxy Lifecycle Hooks - Exposes internal proxy stages as a subscription system to execute custom logic during the request-response lifecycle.
• Body Manipulators - Provides interfaces to intercept and modify the content of HTTP response bodies using raw data buffers.
• Development Proxies - Bypasses CORS restrictions by forwarding local frontend requests to remote backend APIs during development.
• API Gateway Utilities - Acts as a utility for consolidating multiple backend services behind a single entry point to bypass CORS.
• HTTP Clients - Proxy middleware for Express and Connect.
