Why is http4s's use of fs2 (a Scala streaming library) for request/response bodies a natural fit for handling large payloads?
What is the role of an effect system like Cats Effect (commonly paired with http4s) in managing side effects like database calls or logging?
What is an http4s "Client," as distinct from the server-side routing components?
What does it mean for http4s to model HTTP requests and responses as "immutable, pure values"?
How does composing multiple `HttpRoutes[F]` values together (e.g. via `<+>` in http4s) typically work?
What is a practical benefit of http4s's design encouraging small, focused, composable pieces (routes, middleware, decoders) over one large monolithic handler?
What is a general reason understanding Scala's type class pattern (used pervasively in http4s, like `EntityDecoder`) is useful background before working extensively with the library?
Why might a team choose http4s specifically for a service where composability and long-term maintainability of complex request-handling logic (many nested routes, cross-cutting middleware) are significant concerns?
How are routes commonly defined and pattern-matched in http4s?
What does http4s's "middleware" concept typically enable, similarly to middleware in other web frameworks?
Why might the functional, type-safe approach of http4s appeal to a team already invested in functional programming with Scala?
What does it mean that http4s is built to be "backend-agnostic" with respect to the underlying HTTP server implementation (blaze, ember, etc.)?
