Tower middleware and utilities for HTTP clients and servers.

More information about this crate can be found in the crate documentation.

Tower HTTP contains lots of middleware that are generally useful when building HTTP servers and clients. Some of the highlights are:

• Trace adds high level logging of requests and responses. Supports both regular HTTP requests as well as gRPC.
• Compression and Decompression to compress/decompress response bodies.
• FollowRedirect to automatically follow redirection responses.

See the docs for the complete list of middleware.

Middleware uses the http crate as the HTTP interface so they're compatible with any library or framework that also uses http. For example hyper.

The middleware were originally extracted from one of @EmbarkStudios internal projects.

The examples folder contains various examples of how to use Tower HTTP:

• warp-key-value-store: A key/value store with an HTTP API built with warp.
• tonic-key-value-store: A key/value store with a gRPC API and client built with tonic.
• axum-key-value-store: A key/value store with an HTTP API built with axum.

tower-http's MSRV is 1.66.
