+// So far, we've only been working with local state in components
+// We've only seen how to communicate between parent and child components
+// But there are also more general ways to manage global state
+//
+// The three best approaches to global state are
+// 1. Using the router to drive global state via the URL
+// 2. Passing signals through context
+// 3. Creating a global state struct and creating lenses into it with `create_slice`
+//
+// Option #1: URL as Global State
+// The next few sections of the tutorial will be about the router.
+// So for now, we'll just look at options #2 and #3.
+
+// Option #2: Pass Signals through Context
+//
+// In virtual DOM libraries like React, using the Context API to manage global
+// state is a bad idea: because the entire app exists in a tree, changing
+// some value provided high up in the tree can cause the whole app to render.
+//
+// In fine-grained reactive libraries like Leptos, this is simply not the case.
+// You can create a signal in the root of your app and pass it down to other
+// components using provide_context(). Changing it will only cause rerendering
+// in the specific places it is actually used, not the whole app.

+Also note that in some cases, the cfg feature `has_std` will not be set, which may cause build errors with some dependencies which check for `has_std`. You may fix any build errors due to this by adding:
+```toml
+[build]
+rustflags = ["--cfg=has_std"]

 And you'll need to add `panic = "abort"` to `[profile.release]` in `Cargo.toml`. Note that this applies the same `build-std` and panic settings to your server binary, which may not be desirable. Some further exploration is probably needed here.
 
 5. One of the sources of binary size in WASM binaries can be `serde` serialization/deserialization code. Leptos uses `serde` by default to serialize and deserialize resources created with `create_resource`. You might try experimenting with the `miniserde` and `serde-lite` features, which allow you to use those crates for serialization and deserialization instead; each only implements a subset of `serde`’s functionality, but typically optimizes for size over speed.

 Now if you navigate to `/` or to `/users` you’ll get the home page or the `<Users/>`. If you go to `/users/3` or `/blahblah` you’ll get a user profile or your 404 page (`<NotFound/>`).

 This can get a little messy: deriving a signal that wraps an `Option<_>` or `Result<_>` can involve a couple steps. But it’s worth doing this for two reasons:
 
 1. It’s correct, i.e., it forces you to consider the cases, “What if the user doesn’t pass a value for this query field? What if they pass an invalid value?”
-2. It’s performant. Specifically, when you navigate between different paths that match the same `<Route/>` with only params or the query changing, you can get fine-grained updates to different parts of your app without rerendering. For example, navigating between different contacts in our contact-list example does a targeted update to the name field (and eventually contact info) without needing to replacing or rerender the wrapping `<Contact/>`. This is what fine-grained reactivity is for.

 ## A Note about Data-Loading Patterns
 
 Because Actix and (especially) Axum are built on the idea of a single round-trip HTTP request and response, you typically run extractors near the “top” of your application (i.e., before you start rendering) and use the extracted data to determine how that should be rendered. Before you render a `<button>`, you load all the data your app could need. And any given route handler needs to know all the data that will need to be extracted by that route.

 # Responses and Redirects
+
+Extractors provide an easy way to access request data inside server functions. Leptos also provides a way to modify the HTTP response, using the `ResponseOptions` type (see docs for [Actix](https://docs.rs/leptos_actix/latest/leptos_actix/struct.ResponseOptions.html) or [Axum](https://docs.rs/leptos_axum/latest/leptos_axum/struct.ResponseOptions.html)) types and the `redirect` helper function (see docs for [Actix](https://docs.rs/leptos_actix/latest/leptos_actix/fn.redirect.html) or [Axum](https://docs.rs/leptos_axum/latest/leptos_axum/fn.redirect.html)).
+
+## `ResponseOptions`
+
+`ResponseOptions` is provided via context during the initial server rendering response and during any subsequent server function call. It allows you to easily set the status code for the HTTP response, or to add headers to the HTTP response, e.g., to set cookies.
+
+```rust
+#[server(TeaAndCookies)]
+pub async fn tea_and_cookies(cx: Scope) -> Result<(), ServerFnError> {
+	use actix_web::{cookie::Cookie, http::header, http::header::HeaderValue};
+	use leptos_actix::ResponseOptions;
+
+	// pull ResponseOptions from context
+	let response = expect_context::<ResponseOptions>(cx);
+
+	// set the HTTP status code
+	response.set_status(StatusCode::IM_A_TEAPOT);
+
+	// set a cookie in the HTTP response
+	let mut cookie = Cookie::build("biscuits", "yes").finish();
+	if let Ok(cookie) = HeaderValue::from_str(&cookie.to_string()) {
+		res.insert_header(header::SET_COOKIE, cookie);
+	}
+}
+```
+
+## `redirect`
+
+One common modification to an HTTP response is to redirect to another page. The Actix and Axum integrations provide a `redirect` function to make this easy to do. `redirect` simply sets an HTTP status code of `302 Found` and sets the `Location` header.
+
+Here’s a simplified example from our [`session_auth_axum` example](https://github.com/leptos-rs/leptos/blob/a5f73b441c079f9138102b3a7d8d4828f045448c/examples/session_auth_axum/src/auth.rs#L154-L181).
+
+```rust
+#[server(Login, "/api")]
+pub async fn login(
+    cx: Scope,
+    username: String,
+    password: String,
+    remember: Option<String>,
+) -> Result<(), ServerFnError> {
+	// pull the DB pool and auth provider from context
+    let pool = pool(cx)?;
+    let auth = auth(cx)?;
+
+	// check whether the user exists
+    let user: User = User::get_from_username(username, &pool)
+        .await
+        .ok_or_else(|| {
+            ServerFnError::ServerError("User does not exist.".into())
+        })?;
+
+	// check whether the user has provided the correct password
+    match verify(password, &user.password)? {
+		// if the password is correct...
+        true => {
+			// log the user in
+            auth.login_user(user.id);
+            auth.remember_user(remember.is_some());
+
+			// and redirect to the home page
+            leptos_axum::redirect(cx, "/");
+            Ok(())
+        }
+		// if not, return an error
+        false => Err(ServerFnError::ServerError(
+            "Password does not match.".to_string(),
+        )),
+    }
+}
+```
+
+This server function can then be used from your application. This `redirect` works well with the progressively-enhanced `<ActionForm/>` component: without JS/WASM, the server response will redirect because of the status code and header. With JS/WASM, the `<ActionForm/>` will detect the redirect in the server function response, and use client-side navigation to redirect to the new page.

+### Mutating the DOM during rendering
+
+This is a slightly more common way to create a client/server mismatch: updating a signal _during rendering_ in a way that mutates the view.
+
+```rust
+#[component]
+pub fn App(cx: Scope) -> impl IntoView {
+    let (loaded, set_loaded) = create_signal(cx, false);
+
+    // create_effect only runs on the client
+    create_effect(cx, move |_| {
+        // do something like reading from localStorage
+        set_loaded(true);
+    });
+
+    move || {
+        if loaded() {
+            view! { cx, <p>"Hello, world!"</p> }.into_any()
+        } else {
+            view! { cx, <div class="loading">"Loading..."</div> }.into_any()
+        }
+    }
+}
+```
+
+This one gives us the scary panic
+
+```
+panicked at 'assertion failed: `(left == right)`
+  left: `"DIV"`,
+ right: `"P"`: SSR and CSR elements have the same hydration key but different node kinds.
+```
+
+And a handy link to this page!
+
+The problem here is that `create_effect` runs **immediately** and **synchronously**, but only in the browser. As a result, on the server, `loaded` is false, and a `<div>` is rendered. But on the browser, by the time the view is being rendered, `loaded` has already been set to `true`, and the browser is expecting to find a `<p>`.
+
+#### Solution
+
+You can simply tell the effect to wait a tick before updating the signal, by using something like `request_animation_frame`, which will set a short timeout and then update the signal before the next frame.
+
+```rust
+create_effect(cx, move |_| {
+    // do something like reading from localStorage
+    request_animation_frame(move || set_loaded(true));
+});
+```
+
+This allows the browser to hydrate with the correct, matching state (`loaded` is `false` when it reaches the view), then immediately update it to `true` once hydration is complete.
+
 ### Not all client code can run on the server

+
+There are just two problems:
+
+1. Leptos’s view macro doesn’t support specifying a generic on a component with this turbofish syntax.
+2. Even if you could, specifying the correct type here is not possible; closures and functions in general are unnameable types. The compiler can display them with a shorthand, but you can’t specify them.
+
+However, you can get around this by providing a concrete type using `Box<dyn _>` or `&dyn _`:
+
+```rust
+#[component]
+fn ProgressBar(
+    cx: Scope,
+    #[prop(optional)] progress: Option<Box<dyn Fn() -> i32>>,
+) -> impl IntoView {

+
+#[component]
+pub fn App(cx: Scope) -> impl IntoView {
+    view! { cx,
+        <ProgressBar/>
+    }
+}
+```
+
+Because the Rust compiler now knows the concrete type of the prop, and therefore its size in memory even in the `None` case, this compiles fine.
+
+> In this particular case, `&dyn Fn() -> i32` will cause lifetime issues, but in other cases, it may be a possibility.

+# `<AnimatedShow>` combined with CSS animations
+
+This is a very simple example of the `<AnimatedShow>` component.
+
+This component is an extension for the `<Show>` component and it will not take in a fallback, but it will unmount the
+component from the DOM after a given duration. This makes it possible to have really easy unmount animations with just
+CSS.
+
+Just execute `trunk serve` to start the demo.

+# Leptos Query Counter Example
+
+This example creates a simple counter whose state is persisted and synced in the url with query params.
+
+To run it, just issue the `trunk serve --open` command in the example root. This will build the app, run it, and open a new browser to serve it.

+> If you don't have `trunk` installed, [click here for install instructions.](https://trunkrs.dev/)
