//! This example shows how to use middleware in a fullstack Dioxus app.
|
|
//!
|
|
//! Dioxus supports two ways of middleware:
|
|
//! - Applying layers to the top-level axum router
|
|
//! - Apply `#[middleware]` attributes to individual handlers
|
|
|

// We can use the `#[middleware]` attribute to apply middleware to individual handlers.
|
|
//
|
|
// Here, we're applying a timeout to the `per_route_middleware` handler, which will return a 504
|
|
// if the handler takes longer than 3 seconds to complete.
|
|
//
|
|
// To add multiple middleware layers, simply stack multiple `#[middleware]` attributes.
