//! <br>
//!
//! A simple component that reactively renders an icon.
//!
//! To render icons, this crate needs to be coupled with [`icondata`](https://docs.rs/icondata/latest/icondata/),
//! which is an icon source providing over 20,000 icons.
//!
//! # Getting Started
//!
//! In your Cargo.toml, include both `leptos_icons` and `icondata`:
//!
//! ```toml
//! [dependencies]
//! leptos_icons = { version = "{crate_version}" }
//! icondata = { version = "{icondata_version}" }
//! ```
//!
//! In your leptos project, use:
//! ```
//! use leptos::*;
//! use leptos_icons::*;
//!
//! # #[cfg(target_arch = "wasm32")]
//! let _ = view! {
//!     <Icon icon=icondata::BsFolder />
//! };
//! ```
//! [__Complete examples__](https://github.com/Carlosted/leptos-icons/tree/main/examples) are available on github.
