dioxus-clerk 0.1.0

//! Root provider component.
//!
//! Cross-target. On the server: emits a `<script id="__clerk_initial_state">`
//! element and provides context. On wasm: consumes SSR initial state if present,
//! then delegates clerk-js loading and auth updates to the Clerk lifecycle.

/// Root provider. Place at the top of your app or route layout.
///
/// Use exactly one `ClerkProvider` per document: a server render emits a
/// `<script id="__clerk_initial_state">` element, and two providers would
/// produce duplicate element ids.
///
/// Configuration props (`publishable_key`, `options`, `clerk_js_url`, ...)
/// are read once when the provider first mounts, matching clerk-js's
/// load-once model; later prop changes are ignored for the lifetime of the
/// provider instance.
///
/// # Example
///
/// ```no_run
/// use dioxus::prelude::*;
/// use dioxus_clerk::*;
///
/// #[component]
/// fn App() -> Element {
///     // Bake the publishable key in at compile time, e.g.
///     // `env!("CLERK_PUBLISHABLE_KEY")`. `option_env!` keeps builds without
///     // the variable working (the provider then reports a config error).
///     let publishable_key = option_env!("CLERK_PUBLISHABLE_KEY").map(String::from);
///
///     rsx! {
///         ClerkProvider { publishable_key,
///             SignedOut { SignInButton {} }
