Axum demo

Axum: ergonomic and modular web framework built with Tokio, Tower, and Hyper.

Route requests to handlers with a macro free API.
Declaratively parse requests using extractors.
Simple and predictable error handling model.
Generate responses with minimal boilerplate.
Take full advantage of the tower and tower-http ecosystem of middleware, services, and utilities.

Hyper: A fast and correct HTTP implementation for Rust.

HTTP/1 and HTTP/2
Asynchronous design
Leading in performance
Tested and correct
Extensive production use
Client and Server APIs

tower-http: a collection of HTTP specific middleware and utilities built with Tower's Service trait.

Trace: Easily add high level tracing/logging to your application. Supports determining success or failure via status codes as well as gRPC specific headers. Has great defaults but also supports deep customization.
Compression and Decompression: Automatically compress or decompress response bodies. This goes really well with serving static files using ServeDir.
FollowRedirect: Automatically follow redirection responses.

http: a general purpose library of common HTTP types, for examples http::{Request, Response, StatusCode}

Vocabulary

Handler: an async function that accepts zero or more “extractors” as arguments and returns something that can be converted into a response.
Routing: between handlers and request paths
Extractor: a type that implements FromRequest. Extractors are how you pick apart the incoming request to get the parts your handler needs.
Building responses: anything that implements IntoResponse can be returned from a handler
Middleware: used to decorate the application, providing additional functionality

Demo cases

static assets handle
index page
form submit: login
json submit: REST API
json output: struct and json!() macro
query: /search?q=java
Path variables/params /user/:id
404 handler: Separate net("/") and handler_404()
