+// 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.

 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.

+Links and forms sometimes seem completely unrelated. But, in fact, they work in very similar ways.
 
 In plain HTML, there are three ways to navigate to another page:
 
-1. An `<a>` element that links to another page. Navigates to the URL in its `href` attribute with the `GET` HTTP method.
-2. A `<form method="GET">`. Navigates to the URL in its `action` attribute with the `GET` HTTP method and the form data from its inputs encoded in the URL query string.

For better or for worse, HTML forms don’t support `PUT` or `DELETE`, and they don’t support sending JSON. This means that if you use anything but a `GET` or `POST` request with URL-encoded data, it can only work once WASM has loaded. As we’ll see [in a later chapter](../progressive_enhancement), this isn’t always a great idea.

 ## An Important Note on Security
 
 Server functions are a cool technology, but it’s very important to remember. **Server functions are not magic; they’re syntax sugar for defining a public API.** The _body_ of a server function is never made public; it’s just part of your server binary. But the server function is a publicly accessible API endpoint, and it’s return value is just a JSON or similar blob. You should _never_ return something sensitive from a server function.

 These are relatively simple examples accessing basic data from the server. But you can use extractors to access things like headers, cookies, database connection pools, and more, using the exact same `extract()` pattern.
 
+> Note: For now, the Axum `extract` function only supports extractors for which the state is `()`, i.e., you can't yet use it to extract `State(_)`. You can access `State(_)` by using a custom handler that extracts the state and then provides it via context. [Click here for an example](https://github.com/leptos-rs/leptos/blob/a5f73b441c079f9138102b3a7d8d4828f045448c/examples/session_auth_axum/src/main.rs#L91-L92).

 ## 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).

+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.

 It’s pretty rare that you do this intentionally, but it could happen from somehow running different logic on the server and in the browser. If you’re seeing warnings like this and you don’t think it’s your fault, it’s much more likely that it’s a bug with `<Suspense/>` or something. Feel free to go ahead and open an [issue](https://github.com/leptos-rs/leptos/issues) or [discussion](https://github.com/leptos-rs/leptos/discussions) on GitHub for help.
 
+### 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
 
 Imagine you happily import a dependency like `gloo-net` that you’ve been used to using to make requests in the browser, and use it in a `create_resource` in a server-rendered app.
