A minimalist net/http middleware framework for Go that uses only http.Handler for maximum compatibility.
Interpose is a minimalist middleware framework for Go's net/http package. It provides a simple way to manage and chain middleware using only the standard `http.Handler` interface, solving the problem of middleware interoperability and complexity in Go web applications.
Go developers building web applications or APIs who need a lightweight, compatible middleware layer without being locked into a specific framework.
Developers choose Interpose for its strict adherence to net/http standards, ensuring maximum compatibility with existing middleware, and its minimalist design that avoids unnecessary abstractions.

Uses only `http.Handler` and `func(http.Handler)http.Handler`, ensuring seamless integration with any middleware or framework adhering to Go's standard library, such as Gorilla and goji, as highlighted in the README.
Provides no built-in router or middleware, preventing vendor lock-in and allowing developers to compose their stack with preferred components, which is core to its philosophy.
Includes adaptors for non-compliant frameworks like Negroni and Martini, enabling reuse of existing middleware without rewriting, as demonstrated with the `FromNegroni` adaptor in examples.
Applies middleware in first-in-first-out order with nested calls, giving the first middleware added control over the entire request-response cycle, which is detailed in the README's execution diagram.
The recent switch from LIFO to FIFO execution order, mentioned in the README's API change notice, can break existing implementations and requires code updates, posing a migration hurdle.
As a pure middleware manager, it lacks routers, authentication, and other common web components, forcing developers to source them independently and increasing setup complexity.
Being a minimalist project, it has a smaller user base and fewer third-party extensions compared to popular frameworks like Gin or Echo, which might affect long-term support and resources.
