Features

• High-Performance Web Frameworks - A lightweight development environment that maps incoming network requests to handler functions using a fast and flexible routing engine.
• Middleware - Executes reusable logic globally or on specific routes to extend application functionality.
• RESTful API Development - Building scalable web services by mapping URL routes to handler functions and processing structured data formats like JSON and XML.
• Request Pipelines - Implements a modular middleware-centric architecture for sequential request processing and transformation.
• Routing - Organizes related routes into logical collections to simplify application scaling.
• WebSocket Servers - Establishes persistent, bidirectional communication channels between the client and server to enable real-time data exchange.
• JWT Authentication - Validates JSON Web Tokens to confirm user identity and authorize access to protected resources within the application.
• Rate Limiters - Restricts the frequency of requests from individual clients to prevent abuse and ensure service availability for all users.
• Transport Layer Security Configurations - Generates and renews TLS certificates automatically using external services to secure web traffic with encrypted HTTPS connections.
• Data Validation - Automatically maps and validates incoming request payloads into typed objects.
• Middleware Pipelines - Executes a sequence of reusable components to handle cross-cutting concerns like logging and authentication during the request lifecycle.
• Web Servers and Frameworks - A high-performance, minimalist web framework.
• Web Frameworks - Minimalist and extensible web framework.
• Load Balancers - Distributes incoming requests across multiple server instances to improve application availability and maintain consistent performance under heavy loads.
• Reverse Proxies - Forwards incoming requests to secondary services to act as an intermediary for traffic management and load distribution.
• Cross-Site Request Forgery Protections - Validates unique tokens on state-changing requests to protect users against unauthorized actions performed on their behalf.
• Testing Frameworks - Verifies logic by simulating HTTP requests and inspecting responses to ensure handlers and middleware behave as expected.
• Middleware-Driven Request Processing - Executing reusable logic chains to handle cross-cutting concerns like authentication, logging, and security across an entire application.
• Radix Tree Routers - Matches incoming URL paths against registered patterns using a tree structure to ensure efficient and high-performance request dispatching.
• Request Parsers - Extracts headers, query parameters, and body content from incoming requests.
• Response Handlers - Provides a consistent interface for rendering diverse content formats and managing HTTP responses.
• Response Rendering - Sends diverse content formats including JSON, XML, and HTML via a unified interface.
• Graceful Shutdowns - Coordinates the orderly termination of active connections and background tasks to prevent data loss during server restarts.
• HTTP/2 Protocol Implementations - Improves data transmission speed and responsiveness by enabling modern protocol features for communication between server and client.
• Real-Time Web Communication - Establishing persistent bidirectional connections to enable live data exchange between servers and clients for interactive applications.
• API Key Authentication - Validates requests by checking for specific keys in headers or parameters against a predefined list of authorized credentials.
• Cross-Origin Resource Sharing Policies - Configures resource sharing policies to allow web applications on different domains to make requests to your server securely.
• Session & Cookie Handlers - Reads and sets browser cookies to maintain user sessions and store state across multiple client requests.
• Distributed Tracing - Instruments code to export distributed tracing data for monitoring request flows across services.
• Request Timeouts - Cancels requests that exceed a specified duration to prevent hanging connections and free up server resources.
• Request Context - Simplifies state management by providing access to request-specific data.
• Static File Servers - Delivers images, scripts, and stylesheets from a local directory to provide necessary resources for web frontends.
• Request Data Binding - Maps incoming JSON, XML, or form data directly into structured objects to simplify data processing and validation within handlers.
• Microservices Traffic Management - Routing and balancing incoming network traffic across multiple internal services to ensure high availability and efficient resource distribution.
• Server-Sent Events - Pushes real-time updates from the server to the client over a single, long-lived connection using standard event streams.
• Access Control Policies - Enforces access control rules to verify if a user has permission to perform specific actions on protected resources.
• Request Size Limiters - Rejects incoming requests that exceed defined byte limits to protect server resources from excessive data consumption.
• Secure Web Service Deployment - Protecting applications with automated TLS certificate management, request validation, and built-in defenses against common web vulnerabilities.
• Security Headers - Applies security-focused headers to responses to protect users against common web vulnerabilities like cross-site scripting.
• Request Contexts - Provides a centralized container for request and response data to simplify state management and data access across handlers.
• Access Logs - Records traffic metadata like status codes and latency to monitor application activity.
• Graceful Shutdown Mechanisms - Finishes active requests before closing connections during a server shutdown to prevent data loss and ensure clean termination.
• Performance Metrics - Exposes application performance data in standard formats for monitoring tools.
• Query Parameters - Retrieves specific data values from URL strings to process user input.
• Response Compression - Reduces bandwidth usage by compressing response bodies with standard algorithms to improve load times for clients.
