Happstack Lite features and specs

• Lightweight
  Happstack Lite is a minimal, lightweight Haskell web framework, making it an excellent choice for small applications or projects where minimal overhead is desired.
• Haskell Integration
  Being built with Haskell, it provides strong type safety, functional programming paradigms, and powerful abstractions that can help in building robust applications.
• Simple Routing
  Happstack Lite offers straightforward URL routing capabilities, allowing developers to easily define and manage routes in a concise manner.
• Ease of Use
  With its simplified approach, developers new to Haskell or web development can quickly get started with building applications using Happstack Lite.

Possible disadvantages of Happstack Lite

• Limited Features
  As a minimal framework, it may lack some of the advanced features that larger frameworks provide, requiring additional implementation for features like authentication and complex data handling.
• Community and Support
  Happstack Lite may have a smaller community compared to larger frameworks, potentially resulting in less available resources, tutorials, and community support.
• Performance Limitations
  Due to its lightweight nature, it may not be as optimized for high-performance needs as other more comprehensive frameworks.
• Ecosystem Maturity
  The ecosystem surrounding Happstack Lite might be less mature or extensive than that of more established web frameworks, possibly leading to limited library options.

Servant features and specs

• Type-Safe API
  Servant allows you to define APIs at the type level, which means that your server implementation is guaranteed to match the API specification. This type safety minimizes runtime errors and mismatches between the server and client.
• Composability
  Servant's design encourages composition of smaller API components to form larger ones, making it easier to build and maintain complex APIs by reusing existing parts.
• Code Reusability
  By defining APIs as types, you can reuse the same specification for both server and client code, promoting DRY (Don't Repeat Yourself) principles and reducing the risk of discrepancies between client and server.
• Extensibility
  Servant is highly extensible and allows developers to build custom combinators and extend the framework to suit their specific needs or integrate with other Haskell libraries seamlessly.
• Haskell Ecosystem
  Being part of the Haskell ecosystem, Servant benefits from the language's strong type system, concurrency support, and a wide array of libraries.

Possible disadvantages of Servant

• Steep Learning Curve
  Due to its type-level programming and reliance on advanced Haskell features, Servant can be difficult for beginners to grasp quickly. It may require a solid understanding of Haskell's type system.
• Compile-Time Complexity
  Complex APIs can result in long compile times and difficult-to-understand error messages, which can slow down the development process and make debugging harder.
• Limited Resources
  Compared to more mainstream web frameworks and languages, the Haskell community, while growing, is still relatively small. This can result in fewer tutorials, third-party integrative tools, and community support.
• Library Maturity
  While Servant is a powerful tool, it might not yet have the same level of maturity or stability as older frameworks, potentially leading to more frequent breaking changes or less polished features.
