 ## About the Framework
 
 Leptos is a full-stack, isomorphic Rust web framework leveraging fine-grained reactivity to build declarative user interfaces.
@@ -119,7 +113,7 @@ People usually mean one of three things by this question.
 
 1. **Are the APIs stable?** i.e., will I have to rewrite my whole app from Leptos 0.1 to 0.2 to 0.3 to 0.4, or can I write it now and benefit from new features and updates as new versions come?
 
-The APIs are basically settled. We’re adding new features, but we’re very happy with where the type system and patterns have landed. I would not expect major breaking changes to your code to adapt to future releases, in terms of architecture.
+The APIs are basically settled. We’re adding new features, but we’re very happy with where the type system and patterns have landed. I would not expect major breaking changes to your code to adapt to future releases. The sorts of breaking changes that we discuss are things like “Oh yeah, that function should probably take `cx` as its argument...” not major changes to the way you write your application.
 
 2. **Are there bugs?**
 
@@ -158,13 +152,13 @@ There are some practical differences that make a significant difference:
 
 - **Templating:** Leptos uses a JSX-like template format (built on [syn-rsx](https://github.com/stoically/syn-rsx)) for its `view` macro. Sycamore offers the choice of its own templating DSL or a builder syntax.
 - **Server integration:** Leptos provides primitives that encourage HTML streaming and allow for easy async integration and RPC calls, even without WASM enabled, making it easy to opt into integrations between your frontend and backend code without pushing you toward any particular metaframework patterns.
-- **Read-write segregation:** Leptos, like Solid, encourages read-write segregation between signal getters and setters, so you end up accessing signals with tuples like `let (count, set_count) = create_signal(0);` _(If you prefer or if it's more convenient for your API, you can use [`create_rw_signal`](https://docs.rs/leptos/latest/leptos/fn.create_rw_signal.html) to give a unified read/write signal.)_
+- **Read-write segregation:** Leptos, like Solid, encourages read-write segregation between signal getters and setters, so you end up accessing signals with tuples like `let (count, set_count) = create_signal(cx, 0);` _(If you prefer or if it's more convenient for your API, you can use [`create_rw_signal`](https://docs.rs/leptos/latest/leptos/fn.create_rw_signal.html) to give a unified read/write signal.)_
 - **Signals are functions:** In Leptos, you can call a signal to access it rather than calling a specific method (so, `count()` instead of `count.get()`) This creates a more consistent mental model: accessing a reactive value is always a matter of calling a function. For example:
 
   ```rust
-  let (count, set_count) = create_signal(0); // a signal
+  let (count, set_count) = create_signal(cx, 0); // a signal
   let double_count = move || count() * 2; // a derived signal
-  let memoized_count = create_memo(move |_| count() * 3); // a memo
+  let memoized_count = create_memo(cx, move |_| count() * 3); // a memo
   // all are accessed by calling them
   assert_eq!(count(), 0);
   assert_eq!(double_count(), 0);

-# Appendix: How does the Reactive System Work?
-
-You don’t need to know very much about how the reactive system actually works in order to use the library successfully. But it’s always useful to understand what’s going on behind the scenes once you start working with the framework at an advanced level.
-
-The reactive primitives you use are divided into three sets:
-
-- **Signals** (`ReadSignal`/`WriteSignal`, `RwSignal`, `Resource`, `Trigger`) Values you can actively change to trigger reactive updates.
-- **Computations** (`Memo`s) Values that depend on signals (or other computations) and derive a new reactive value through some pure computation.
-- **Effects** Observers that listen to changes in some signals or computations and run a function, causing some side effect.
-
-Derived signals are a kind of non-primitve computation: as plain closures, they simply allow you to refactor some repeated signal-based computation into a reusable function that can be called in multiple places, but they are not represented in the reactive system itself.
-
-All the other primitives actually exist in the reactive system as nodes in a reactive graph.
-
-Most of the work of the reactive system consists of propagating changes from signals to effects, possibly through some intervening memos.
-
-The assumption of the reactive system is that effects (like rendering to the DOM or making a network request) are orders of magnitude more expensive than things like updating a Rust data structure inside your app.
-
-So the **primary goal** of the reactive system is to **run effects as infrequently as possible**.
-
-Leptos does this through the construction of a reactive graph.
-
-> Leptos’s current reactive system is based heavily on the [Reactively](https://github.com/modderme123/reactively) library for JavaScript. You can read Milo’s article “[Super-Charging Fine-Grained Reactivity](https://dev.to/modderme123/super-charging-fine-grained-reactive-performance-47ph)” for an excellent account of its algorithm, as well as fine-grained reactivity in general—including some beautiful diagrams!
-
-## The Reactive Graph
-
-Signals, memos, and effects all share three characteristics:
-
-- **Value** They have a current value: either the signal’s value, or (for memos and effects) the value returned by the previous run, if any.
-- **Sources** Any other reactive primitives they depend on. (For signals, this is an empty set.)
-- **Subscribers** Any other reactive primitives that depend on them. (For effects, this is an empty set.)
-
-In reality then, signals, memos, and effects are just conventional names for one generic concept of a “node” in a reactive graph. Signals are always “root nodes,” with no sources/parents. Effects are always “leaf nodes,” with no subscribers. Memos typically have both sources and subscribers.
-
-### Simple Dependencies
-
-So imagine the following code:
-
-```rust
-// A
-let (name, set_name) = create_signal("Alice");
-
-// B
-let name_upper = create_memo(move |_| name.with(|n| n.to_uppercase()));
-
-// C
-create_effect(move |_| {
-	log!("{}", name_upper());
-});
-
-set_name("Bob");
-```
-
-You can easily imagine the reactive graph here: `name` is the only signal/origin node, the `create_effect` is the only effect/terminal node, and there’s one intervening memo.
-
-```
-A   (name)
-|
-B   (name_upper)
-|
-C   (the effect)
-```
-
-### Splitting Branches
-
-Let’s make it a little more complex.
-
-```rust
-// A
-let (name, set_name) = create_signal("Alice");
-
-// B
-let name_upper = create_memo(move |_| name.with(|n| n.to_uppercase()));
-
-// C
-let name_len = create_memo(move |_| name.len());
-
-// D
-create_effect(move |_| {
-	log!("len = {}", name_len());
-});
-
-// E
-create_effect(move |_| {
-	log!("name = {}", name_upper());
-});
-```
-
-This is also pretty straightforward: a signal source signal (`name`/`A`) divides into two parallel tracks: `name_upper`/`B` and `name_len`/`C`, each of which has an effect that depends on it.
-
-```
- __A__
-|     |
-B     C
-|     |
-D     E
-```
-
-Now let’s update the signal.
-
-```rust
-set_name("Bob");
-```
-
-We immediately log
-
-```
-len = 3
-name = BOB
-```
-
-Let’s do it again.
-
-```rust
-set_name("Tim");
-```
-
-The log should shows
-
-```
-name = TIM
-```
-
-`len = 3` does not log again.
-
-Remember: the goal of the reactive system is to run effects as infrequently as possible. Changing `name` from `"Bob"` to `"Tim"` will cause each of the memos to re-run. But they will only notify their subscribers if their value has actually changed. `"BOB"` and `"TIM"` are different, so that effect runs again. But both names have the length `3`, so they do not run again.
-
-### Reuniting Branches
-
-One more example, of what’s sometimes called **the diamond problem**.
-
-```rust
-// A
-let (name, set_name) = create_signal("Alice");
-
-// B
-let name_upper = create_memo(move |_| name.with(|n| n.to_uppercase()));
-
-// C
-let name_len = create_memo(move |_| name.len());
-
-// D
-create_effect(move |_| {
-	log!("{} is {} characters long", name_upper(), name_len());
-});
-```
-
-What does the graph look like for this?
-
-```
- __A__
-|     |
-B     C
-|     |
-|__D__|
-```
-
-You can see why it's called the “diamond problem.” If I’d connected the nodes with straight lines instead of bad ASCII art, it would form a diamond: two memos, each of which depend on a signal, which feed into the same effect.
-
-A naive, push-based reactive implementation would cause this effect to run twice, which would be bad. (Remember, our goal is to run effects as infrequently as we can.) For example, you could implement a reactive system such that signals and memos immediately propagate their changes all the way down the graph, through each dependency, essentially traversing the graph depth-first. In other words, updating `A` would notify `B`, which would notify `D`; then `A` would notify `C`, which would notify `D` again. This is both inefficient (`D` runs twice) and glitchy (`D` actually runs with the incorrect value for the second memo during its first run.)
-
-## Solving the Diamond Problem
-
-Any reactive implementation worth its salt is dedicated to solving this issue. There are a number of different approaches (again, [see Milo’s article](https://dev.to/modderme123/super-charging-fine-grained-reactive-performance-47ph) for an excellent overview).
-
-Here’s how ours works, in brief.
-
-A reactive node is always in one of three states:
-
-- `Clean`: it is known not to have changed
-- `Check`: it is possible it has changed
-- `Dirty`: it has definitely changed
-
-Updating a signal `Dirty` marks that signal `Dirty`, and marks all its descendants `Check`, recursively. Any of its descendants that are effects are added to a queue to be re-run.
-
-```
-    ____A (DIRTY)___
-   |               |
-B (CHECK)    C (CHECK)
-   |               |
-   |____D (CHECK)__|
-```
-
-Now those effects are run. (All of the effects will be marked `Check` at this point.) Before re-running its computation, the effect checks its parents to see if they are dirty. So
-
-- So `D` goes to `B` and checks if it is `Dirty`.
-- But `B` is also marked `Check`. So `B` does the same thing:
-  - `B` goes to `A`, and finds that it is `Dirty`.
-  - This means `B` needs to re-run, because one of its sources has changed.
-  - `B` re-runs, generating a new value, and marks itself `Clean`
-  - Because `B` is a memo, it then checks its prior value against the new value.
-  - If they are the same, `B` returns "no change." Otherwise, it returns "yes, I changed."
-- If `B` returned “yes, I changed,” `D` knows that it definitely needs to run and re-runs immediately before checking any other sources.
-- If `B` returned “no, I didn’t change,” `D` continues on to check `C` (see process above for `B`.)
-- If neither `B` nor `C` has changed, the effect does not need to re-run.
-- If either `B` or `C` did change, the effect now re-runs.
-
-Because the effect is only marked `Check` once and only queued once, it only runs once.
-
-If the naive version was a “push-based” reactive system, simply pushing reactive changes all the way down the graph and therefore running the effect twice, this version could be called “push-pull.” It pushes the `Check` status all the way down the graph, but then “pulls” its way back up. In fact, for large graphs it may end up bouncing back up and down and left and right on the graph as it tries to determine exactly which nodes need to re-run.
-
-**Note this important trade-off**: Push-based reactivity propagates signal changes more quickly, at the expense of over-re-running memos and effects. Remember: the reactive system is designed to minimize how often you re-run effects, on the (accurate) assumption that side effects are orders of magnitude more expensive than this kind of cache-friendly graph traversal happening entirely inside the library’s Rust code. The measurement of a good reactive system is not how quickly it propagates changes, but how quickly it propagates changes _without over-notifying_.
-
-## Memos vs. Signals
-
-Note that signals always notify their children; i.e., a signal is always marked `Dirty` when it updates, even if its new value is the same as the old value. Otherwise, we’d have to require `PartialEq` on signals, and this is actually quite an expensive check on some types. (For example, add an unnecessary equality check to something like `some_vec_signal.update(|n| n.pop())` when it’s clear that it has in fact changed.)
-
-Memos, on the other hand, check whether they change before notifying their children. They only run their calculation once, no matter how many times you `.get()` the result, but they run whenever their signal sources change. This means that if the memo’s computation is _very_ expensive, you may actually want to memoize its inputs as well, so that the memo only re-calculates when it is sure its inputs have changed.
-
-## Memos vs. Derived Signals
-
-All of this is cool, and memos are pretty great. But most actual applications have reactive graphs that are quite shallow and quite wide: you might have 100 source signals and 500 effects, but no memos or, in rare case, three or four memos between the signal and the effect. Memos are extremely good at what they do: limiting how often they notify their subscribers that they have changed. But as this description of the reactive system should show, they come with overhead in two forms:
-
-1. A `PartialEq` check, which may or may not be expensive.
-2. Added memory cost of storing another node in the reactive system.
-3. Added computational cost of reactive graph traversal.
-
-In cases in which the computation itself is cheaper than this reactive work, you should avoid “over-wrapping” with memos and simply use derived signals. Here’s a great example in which you should never use a memo:
-
-```rust
-let (a, set_a) = create_signal(1);
-// none of these make sense as memos
-let b = move || a() + 2;
-let c = move || b() % 2 == 0;
-let d = move || if c() { "even" } else { "odd" };
-
-set_a(2);
-set_a(3);
-set_a(5);
-```
-
-Even though memoizing would technically save an extra calculation of `d` between setting `a` to `3` and `5`, these calculations are themselves cheaper than the reactive algorithm.
-
-At the very most, you might consider memoizing the final node before running some expensive side effect:
-
-```rust
-let text = create_memo(move |_| {
-  d()
-});
-create_effect(move |_| {
-  engrave_text_into_bar_of_gold(&text());
-});
-```

 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

-# 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.
-

-
-## 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

-## 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(0);
-
-let stop = watch(

 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/>`). On every navigation, the router determines which `<Route/>` should be matched, and therefore what content should be displayed where the `<Routes/>` component is defined.

 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();
-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.

 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.
 
-The Axum `extract` function only supports extractors for which the state is `()`. If you need an extractor that uses `State`, you should use [`extract_with_state`](https://docs.rs/leptos_axum/latest/leptos_axum/fn.extract_with_state.html). This requires you to provide the state. You can do this by extending the existing `LeptosOptions` state using the Axum `FromRef` pattern, which providing the state as context during render and server functions with custom handlers.

+> To see the full setup, check out the tests for the [`counter`](https://github.com/leptos-rs/leptos/tree/main/examples/counter) example.
+
+### Writing Your Tests
+
+Most tests will involve some combination of vanilla DOM manipulation and comparison to a `view`. For example, here’s a test [for the
+`counter` example](https://github.com/leptos-rs/leptos/blob/main/examples/counter/tests/web.rs).
+
+First, we set up the testing environment.
+
+```rust
+use wasm_bindgen_test::*;
+use counter::*;
+use leptos::*;
+use web_sys::HtmlElement;
+
+// tell the test runner to run tests in the browser
+wasm_bindgen_test_configure!(run_in_browser);
+```
+
+I’m going to create a simpler wrapper for each test case, and mount it there.
+This makes it easy to encapsulate the test results.
+
+```rust
+// like marking a regular test with #[test]
 #[wasm_bindgen_test]
 fn clear() {
     let document = leptos::document();
     let test_wrapper = document.create_element("section").unwrap();
-    let _ = document.body().unwrap().append_child(&test_wrapper);
+    document.body().unwrap().append_child(&test_wrapper);
 
+    // start by rendering our counter and mounting it to the DOM
+    // note that we start at the initial value of 10
     mount_to(
         test_wrapper.clone().unchecked_into(),
         || view! { <SimpleCounter initial_value=10 step=1/> },
     );
+}
+```
 
-    let div = test_wrapper.query_selector("div").unwrap().unwrap();
-    let clear = test_wrapper
-        .query_selector("button")
-        .unwrap()
-        .unwrap()
-        .unchecked_into::<web_sys::HtmlElement>();
+We’ll use some manual DOM operations to grab the `<div>` that wraps
+the whole component, as well as the `clear` button.
 
-    clear.click();
+```rust
+// now we extract the buttons by iterating over the DOM
+// this would be easier if they had IDs
+let div = test_wrapper.query_selector("div").unwrap().unwrap();
+let clear = test_wrapper
+    .query_selector("button")
+    .unwrap()
+    .unwrap()
+    .unchecked_into::<web_sys::HtmlElement>();
+```
+
+Now we can use ordinary DOM APIs to simulate user interaction.
+
+```rust
+// now let's click the `clear` button
+clear.click();
+```
+

+the wrapper’s `innerHTML` against another comparison case.

-> #### Why do you need `prop:value`?
-> 
-> Web browsers are the most ubiquitous and stable platform for rendering graphical user interfaces in existence. They have also maintained an incredible backwards compatibility over their three decades of existence. Inevitably, this means there are some quirks.
-> 
-> One odd quirk is that there is a distinction between HTML attributes and DOM element properties, i.e., between something called an “attribute” which is parsed from HTML and can be set on a DOM element with `.setAttribute()`, and something called a “property” which is a field of the JavaScript class representation of that parsed HTML element.
->
-> In the case of an `<input value=...>`, setting the `value` *attribute* is defined as setting the initial value for the input, and setting `value` *property* sets its current value. It maybe easiest to understand this by opening `about:blank` and running the following JavaScript in the browser console, line by line:
-> 
-> ```js
-> // create an input and append it to the DOM
-> const el = document.createElement("input")
-> document.body.appendChild(el)
-> 
-> el.setAttribute("value", "test") // updates the input
-> el.setAttribute("value", "another test") // updates the input again
-> 
-> // now go and type into the input: delete some characters, etc.
-> 
-> el.setAttribute("value", "one more time?") 
-> // nothing should have changed. setting the "initial value" does nothing now
-> 
-> // however...
-> el.value = "But this works"
-> ```
->
-> Many other frontend frameworks conflate attributes and properties, or create a special case for inputs that sets the value correctly. Maybe Leptos should do this too; but for now, I prefer giving users the maximum amount of control over whether they’re setting an attribute or a property, and doing my best to educate people about the actual underlying browser behavior rather than obscuring it.

-# 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. Test scenarios are grouped by the **user action** and the **object** of that action. This makes it easier to locate and reason about requirements.
-
-Here is a brief overview of how things fit together.
-
-```bash
-features
-└── {action}_{object}.feature   # 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
-└── app_suite.rs                # Test main
