Framework 3: Revel

Revel is a full-stack web framework for Go that follows the Model-View-Controller (MVC) architectural pattern. It provides a comprehensive set of features for building web applications, including routing, templating, ORM (Object-Relational Mapping), and more. The framework also promotes code organization and maintainability by offering a structured approach to application development.

Key Features of Revel

Convention over Configuration: Revel follows tradition over configuration, providing sensible defaults and predefined patterns. This minimizes the need for extensive structure, allowing you to focus on building their application logic.

Full-Stack Framework: Revel is a full-stack web framework that provides a comprehensive set of features out of the box. It includes routing, request handling, templating, ORM (Object-Relational Mapping), caching, and more, making it suitable for building robust and feature-rich web applications.

Scalability: Revel is suitable for handling high-traffic and high-performance applications. It provides:

• Automatic request routing.
• Efficiently mapping requests to controllers.
• Allowing developers to build scalable applications that can take many concurrent requests.

Hot Code Reloading: Revel supports hot code reloading, which means you can see code changes immediately without requiring manual recompilation or application restarting. This feature speeds up your development process and enables quick iterations.

Integrated Testing: Revel includes a built-in testing framework that simplifies the creation and execution of tests. You can write comprehensive test suites to verify the functionality of your applications, ensuring reliability and stability.

Modularity: Revel encourages modularity and follows the MVC (Model-View-Controller) architectural pattern. It clearly separates the application's business logic, presentation layer, and data persistence, enabling developers to write maintainable and scalable code.

Revel Use Cases

Framework 4: Fast HTTP

Fast HTTP is a compact version of the traditional HTTP profile optimized for speed in ideal traffic. The performance HTTP virtual server is merged with a Fast HTTP profile to speed up specific types of HTTP connections and reduce back-end HTTP server connections. However, Fast HTTP may not be an appropriate profile when network conditions are less than optimal. When load balancing Internet-based traffic, F5 usually recommends the HTTP profile.

Key Feature of Fast HTTP

HTTP/2 Support: Fast HTTP supports the HTTP/2 protocol, which offers significant performance improvements over its predecessor, HTTP/1.1. HTTP/2 introduces features like request multiplexing, header compression, and server push, which enhance data transmission efficiency and reduce latency. 

Easy Integration: Fast HTTP provides a straightforward API, which you can integrate into existing systems. With its compatibility with Go frameworks and libraries, you can leverage its performance enhancements without significant changes to your codebase. 

Advanced Caching Mechanisms: Fast HTTP includes built-in support for caching mechanisms, such as ETag, Last-Modified, and Expires headers. These mechanisms allow servers to cache responses and serve subsequent requests from the cache, reducing the load on backend systems and improving response times. 

Fast HTTP Use Cases

• Packet-by-packet Functionality: Fast HTTP operates on a packet-by-packet level to make decisions and forward the packet as soon as possible after receipt of the packet. When you enable a Fast HTTP profile for a virtual server, the system only buffers enough data to parse packet headers.
  
  
• SNAT Functionality: Fast HTTP automatically applies a SNAT to all client traffic. The SNAT can be either a SNAT pool or the BIG-IP self-IP addresses configured for the VLAN closest to the node's subnet. From the node's perspective, all Fast HTTP-processed connections appear to come directly from the BIG-IP itself, and the source client IP information is not retained.
  
  
• OneConnect Functionality: Fast HTTP incorporates basic OneConnect functionality to minimize the latency of TCP three-way handshakes between the BIG-IP system and the node. Whenever possible, Fast HTTP chooses to re-use an existing connection to a node rather than create a new one.

Framework 5: Gorilla

The Gorilla Mux toolkit is among the most prevalent routers in the GoLang ecosystem. The most popular application of Gorilla is Geth due to its diverse package features. Gorilla offers widespread functionalities for router matching, static file servering, SPA servering, CORS request handling, middleware, and testing capabilities.

Gorilla Key Features

Compatibility with Standard HTTP: The Gorilla framework implements the http.Handler interface, making it compatible with the standard http.ServeMux. This allows seamless integration with existing HTTP infrastructure and libraries.

Flexible Request Matching: Requests can be matched based on various criteria, including URL host, path, path prefix, schemes, headers, query values, HTTP methods, or custom matches. This provides flexibility in defining routing rules and allows for fine-grained control over request handling.

Variable Support: URL hosts, paths, and query values can contain variables with optional regular expressions. This enables dynamic matching and parameter extraction from incoming requests, making handling dynamic or variable parts of URLs easier.

URL Building and Reversing: The framework provides functionality to build or "reverse" registered URLs. This feature assists in maintaining references to resources by automatically generating URLs based on registered routes. It helps ensure consistency and avoids hard-coding URLs throughout the application.

Subrouter Support: Routes can be sub-routers, allowing for nested routes within the main routing structure. You can only test Nested routes if the parent route matches, enabling the definition of groups of routes that share common conditions such as a host, path prefix, or other repeated attributes. This promotes code organization and optimization of request matching.

Gorilla Use Cases

• WebSocket Applications: Gorilla provides excellent support for WebSocket communication, including a package that simplifies WebSocket handling and provides functionality for bidirectional real-time communication between the server and clients.
  
  
• Single Sign-On (SSO) Integration: Gorilla's flexible routing and request matching capabilities are beneficial when integrating with Single Sign-On providers like OAuth or OpenID Connect. You can define routes for handling authentication callbacks, token exchanges, and user profile retrieval, simplifying the integration process.
  
  
• Session Management: Gorilla includes a package to facilitate session management in web applications. You can easily store and retrieve session data, set session options, and manage session lifetimes, which helps to implement user authentication, store user preferences, or maintain a session-based state.
