mobiler_web/
lib.rs

1//! `mobiler-web` — Mobiler's web shell.
2//!
3//! Renders **any** Mobiler app's `Widget` tree to the DOM (Leptos / WASM), driving
4//! the Rust core via crux's `Core` and fulfilling capabilities (HTTP) with the
5//! browser's `fetch`. The web twin of the generic Android/SwiftUI shells: write
6//! your app once as a `MobilerApp`, then
7//!
8//! ```ignore
9//! fn main() { mobiler_web::run::<my_app::App>(); }
10//! ```
11//!
12//! renders it on the web — fully styled, no CSS required: the shell ships its own
13//! theme (`mobiler.css`) and injects it on mount, and `Scaffold.dark_mode` flips
14//! the whole theme. Your crate only supplies a minimal `index.html` with the Trunk
15//! entry point; an app may add its own stylesheet to override any widget class.
