 The `nightly` feature enables the function call syntax for accessing and setting signals, as opposed to `.get()` and `.set()`. This leads to a consistent mental model in which accessing a reactive value of any kind (a signal, memo, or derived signal) is always represented as a function call. This is only possible with nightly Rust and the `nightly` feature.
 
-> Note: The `nightly` feature is present on the main branch version right now, but not in 0.3.x. For 0.3.x, nightly is the default and `stable` has a special feature.

 Here, instead of reading from the state signal directly, we create “slices” of that state with fine-grained updates via `create_slice`. Each slice signal only updates when the particular piece of the larger struct it accesses updates. This means you can create a single root signal, and then take independent, fine-grained slices of it in different components, each of which can update without notifying the others of changes.

 This inversion of the flow of control makes it easier to add or remove individual resources, as you don’t need to handle the matching yourself. It also unlocks some massive performance improvements during server-side rendering, which we’ll talk about during a later chapter.
 
+## `<Await/>`
+
+In you’re simply trying to wait for some `Future` to resolve before rendering, you may find the `<Await/>` component helpful in reducing boilerplate. `<Await/>` essentially combines a resource with the source argument `|| ()` with a `<Suspense/>` with no fallback.
+
+In other words:
+
+1. It only polls the `Future` once, and does not respond to any reactive changes.
+2. It does not render anything until the `Future` resolves.
+3. After the `Future` resolves, its binds its data to whatever variable name you choose and then renders its children with that variable in scope.
+
+```rust
+async fn fetch_monkeys(monkey: i32) -> i32 {
+    // maybe this didn't need to be async
+    monkey * 2
+}
+view! { cx,
+    <Await
+        // `future` provides the `Future` to be resolved
+        future=|cx| fetch_monkeys(3)
+        // the data is bound to whatever variable name you provide
+        bind:data
+    >
+        // you receive the data by reference and can use it in your view here
+        <p>{*data} " little monkeys, jumping on the bed."</p>

+# Deployment
+
+There are as many ways to deploy a web application as there are developers, let alone applications. But there are a couple useful tips to keep in mind when deploying an app.
+
+## General Advice
+
+1. Remember: Always deploy Rust apps built in `--release` mode, not debug mode. This has a huge effect on both performance and binary size.
+2. Test locally in release mode as well. The framework applies certain optimizations in release mode that it does not apply in debug mode, so it’s possible for bugs to surface at this point. (If your app behaves differently or you do encounter a bug, it’s likely a framework-level bug and you should open a GitHub issue with a reproduction.)
+
+> We asked users to submit their deployment setups to help with this chapter. I’ll quote from them below, but you can read the full thread [here](https://github.com/leptos-rs/leptos/issues/1152).
+
+## Deploying a Client-Side-Rendered App
+
+If you’ve been building an app that only uses client-side rendering, working with Trunk as a dev server and build tool, the process is quite easy.
+
+```bash
+trunk build --release
+```
+
+`trunk build` will create a number of build artifacts in a `dist/` directory. Publishing `dist` somewhere online should be all you need to deploy your app. This should work very similarly to deploying any JavaScript application.
+
+> Read more: [Deploying to Vercel with GitHub Actions](https://github.com/leptos-rs/leptos/issues/1152#issuecomment-1577861900).
+
+## Deploying a Full-Stack App
+
+The most popular way for people to deploy full-stack apps built with `cargo-leptos` is to use a cloud hosting service that supports deployment via a Docker build. Here’s a sample `Dockerfile`, which is based on the one we use to deploy the Leptos website.
+
+```dockerfile

 Every time `count` is updated, this effect wil rerun. This is what allows reactive, fine-grained updates to the DOM.
 
+## Explicit, Cancelable Tracking with `watch`
+
+In addition to `create_effect`, Leptos provides a [`watch`](https://docs.rs/leptos_reactive/latest/leptos_reactive/fn.watch.html) function, which can be used for two main purposes:
+
+1. Separating tracking and responding to changes by explicitly passing in a set of values to track.
+2. Canceling tracking by calling a stop function.
+
+Like `create_resource`, `watch` takes a first argument, which is reactively tracked, and a second, which is not. Whenever a reactive value in its `deps` argument is changed, the `callback` is run. `watch` returns a function that can be called to stop tracking the dependencies.
+
+```rust
+let (num, set_num) = create_signal(cx, 0);
+
+let stop = watch(
+    cx,
+    move || num.get(),
+    move |num, prev_num, _| {

 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/>`).

@@ -11,11 +11,27 @@ The router will bail out of handling an `<a>` click under a number of situations
 
 In other words, the router will only try to do a client-side navigation when it’s pretty sure it can handle it, and it will upgrade every `<a>` element to get this special behavior.
 
+> This also means that if you need to opt out of client-side routing, you can do so easily. For example, if you have a link to another page on the same domain, but which isn’t part of your Leptos app, you can just use `<a rel="external">` to tell the router it isn’t something it can handle.
+
 The router also provides an [`<A>`](https://docs.rs/leptos_router/latest/leptos_router/fn.A.html) component, which does two additional things:
 
 1. Correctly resolves relative nested routes. Relative routing with ordinary `<a>` tags can be tricky. For example, if you have a route like `/post/:id`, `<A href="1">` will generate the correct relative route, but `<a href="1">` likely will not (depending on where it appears in your view.) `<A/>` resolves routes relative to the path of the nested route within which it appears.
 2. Sets the `aria-current` attribute to `page` if this link is the active link (i.e., it’s a link to the page you’re on). This is helpful for accessibility and for styling. For example, if you want to set the link a different color if it’s a link to the page you’re currently on, you can match this attribute with a CSS selector.
 
+## Navigating Programmatically
+
+Your most-used methods of navigating between pages should be with `<a>` and `<form>` elements or with the enhanced `<A/>` and `<Form/>` components. Using links and forms to navigate is the best solution for accessibility and graceful degradation.
+
+On occasion, though, you’ll want to navigate programmatically, i.e., call a function that can navigate to a new page. In that case, you should use the [`use_navigate`](https://docs.rs/leptos_router/latest/leptos_router/fn.use_navigate.html) function.
+```rust
+let navigate = leptos_router::use_navigate(cx);
+navigate("/somewhere", Default::default());
+```
+
+> You should almost never do something like `<button on:click=move |_| navigate(/* ... */)>`. Any `on:click` that navigates should be an `<a>`, for reasons of accessibility.
+
+The second argument here is a set of [`NavigateOptions`](https://docs.rs/leptos_router/latest/leptos_router/struct.NavigateOptions.html), which includes options to resolve the navigation relative to the current route as the `<A/>` component does, replace it in the navigation stack, include some navigation state, and maintain the current scroll state on navigation.
+
 > Once again, this is the same example. Check out the relative `<A/>` components, and take a look at the CSS in `index.html` to see the ARIA-based styling.

+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

+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.

+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/)

+# E2E Testing
+
+This example demonstrates e2e testing with Rust using executable requirements.
+
+## Testing Stack
+
+|    |      Role      |  Description |
+|---|---|---|
+| [Cucumber](https://github.com/cucumber-rs/cucumber/tree/main) | Test Runner | Run [Gherkin](https://cucumber.io/docs/gherkin/reference/) specifications as Rust tests |
+| [Fantoccini](https://github.com/jonhoo/fantoccini/tree/main) | Browser Client | Interact with web pages through WebDriver |
+| [Cargo Leptos ](https://github.com/leptos-rs/cargo-leptos) | Build Tool |  Compile example and start the server and end-2-end tests |
+| [chromedriver](https://chromedriver.chromium.org/downloads) | WebDriver | Provide WebDriver for Chrome
+
+## Testing Organization
+
+Testing is organized around what a user can do and see/not see.
+
+Here is a brief overview of how things fit together.
+
+```bash
+features                    # Specify test scenarios
+tests
+├── fixtures
+│   ├── action.rs           # Perform a user action (click, type, etc.)
+│   ├── check.rs            # Assert what a user can see/not see
+│   ├── find.rs             # Query page elements
+│   ├── mod.rs

+# E2E Testing
+
+This example demonstrates e2e testing with Rust using executable requirements.
+
+## Testing Stack
+
+|    |      Role      |  Description |
+|---|---|---|
+| [Cucumber](https://github.com/cucumber-rs/cucumber/tree/main) | Test Runner | Run [Gherkin](https://cucumber.io/docs/gherkin/reference/) specifications as Rust tests |
+| [Fantoccini](https://github.com/jonhoo/fantoccini/tree/main) | Browser Client | Interact with web pages through WebDriver |
+| [Cargo Leptos ](https://github.com/leptos-rs/cargo-leptos) | Build Tool |  Compile example and start the server and end-2-end tests |
+| [chromedriver](https://chromedriver.chromium.org/downloads) | WebDriver | Provide WebDriver for Chrome
+
+## Testing Organization
+
+Testing is organized around what a user can do and see/not see.
+
+Here is a brief overview of how things fit together.
+
+```bash
+features                    # Specify test scenarios
+tests
+├── fixtures
+│   ├── action.rs           # Perform a user action (click, type, etc.)
+│   ├── check.rs            # Assert what a user can see/not see
+│   ├── find.rs             # Query page elements
+│   ├── mod.rs
+│   └── world
+│       ├── action_steps.rs # Map Gherkin steps to user actions
+│       ├── check_steps.rs  # Map Gherkin steps to user expectations
+│       └── mod.rs
+└── manage_todos.rs         # Test main 
+```
