dioxus/examples/login_form.rs

//! Implementing a login form
//!
//! This example demonstrates how to implement a login form using Dioxus desktop. Since forms typically navigate the
//! page on submit, we need to intercept the onsubmit event and send a request to a server. On the web, we could
//! just leave the submit action` as is, but on desktop, we need to handle the form submission ourselves.
//!
//! Todo: actually spin up a server and run the login flow. Login is way more complex than a form override :)
