dioxus/examples/hydration.rs

//! Example: real-world usage of hydration
//! ------------------------------------
//!
//! This example shows how to pre-render a page using dioxus SSR and then how to rehydrate it on the client side.
//!
//! To accomplish hydration on the web, you'll want to set up a slightly more sophisticated build & bundle strategy. In
//! the official docs, we have a guide for using DioxusStudio as a build tool with pre-rendering and hydration.
//!
//! In this example, we pre-render the page to HTML and then pass it into the desktop configuration. This serves as a
//! proof-of-concept for the hydration feature, but you'll probably only want to use hydration for the web.
