 ## FAQs
 
-### What’s up with the name?
-
-*Leptos* (λεπτός) is an ancient Greek word meaning “thin, light, refine, fine-grained.” To me, a classicist and not a dog owner, it evokes the lightweight reactive system that powers the framework. I've since learned the same word is at the root of the medical term “leptospirosis,” a blood infection that affects humans and animals... My bad. No dogs were harmed in the creation of this framework.
-
 ### Is it production ready?
 
 People usually mean one of three things by this question.

-# Loading Data with Resources
-
-A [Resource](https://docs.rs/leptos/latest/leptos/struct.Resource.html) is a reactive data structure that reflects the current state of an asynchronous task, allowing you to integrate asynchronous `Future`s into the synchronous reactive system. Rather than waiting for its data to load with `.await`, you transform the `Future` into a signal that returns `Some(T)` if it has resolved, and `None` if it’s still pending.
-
-You do this by using the [`create_resource`](https://docs.rs/leptos/latest/leptos/fn.create_resource.html) function. This takes two arguments (other than the ubiquitous `cx`):
-
-1. a source signal, which will generate a new `Future` whenever it changes
-2. a fetcher function, which takes the data from that signal and returns a `Future`
-
-Here’s an example
-
-```rust
-// our source signal: some synchronous, local state
-let (count, set_count) = create_signal(cx, 0);
-
-// our resource
-let async_data = create_resource(cx,
-	count,
-	// every time `count` changes, this will run
-	|value| async move {
-		log!("loading data from API");
-		load_data(value).await
-	},
-);
-```
-
-To create a resource that simply runs once, you can pass a non-reactive, empty source signal:
-
-```rust
-let once = create_resource(cx, || (), |_| async move { load_data().await });
-```
-
-To access the value you can use `.read(cx)` or `.with(cx, |data| /* */)`. These work just like `.get()` and `.with()` on a signal—`read` clones the value and returns it, `with` applies a closure to it—but with two differences
-
-1. For any `Resource<_, T>`, they always return `Option<T>`, not `T`: because it’s always possible that your resource is still loading.
-2. They take a `Scope` argument. You’ll see why in the next chapter, on `<Suspense/>`.
-
-So, you can show the current state of a resource in your view:
-
-```rust
-let once = create_resource(cx, || (), |_| async move { load_data().await });
-view! { cx,
-	<h1>"My Data"</h1>
-	{move || match once.read(cx) {
-		None => view! { cx, <p>"Loading..."</p> }.into_view(cx),
-		Some(data) => view! { cx, <ShowData data/> }.into_view(cx)
-	}}
-}
-```
-
-Resources also provide a `refetch()` method that allow you to manually reload the data (for example, in response to a button click) and a `loading()` method that returns a `ReadSignal<bool>` indicating whether the resource is currently loading or not.

-# `<Suspense/>`
-
-In the previous chapter, we showed how you can create a simple loading screen to show some fallback while a resource is loading.
-
-```rust
-let (count, set_count) = create_signal(cx, 0);
-let a = create_resource(cx, count, |count| async move { load_a(count).await });
-
-view! { cx,
-	<h1>"My Data"</h1>
-	{move || match once.read(cx) {
-		None => view! { cx, <p>"Loading..."</p> }.into_view(cx),
-		Some(data) => view! { cx, <ShowData data/> }.into_view(cx)
-	}}
-}
-```
-
-But what if we have two resources, and want to wait for both of them?
-
-```rust
-let (count, set_count) = create_signal(cx, 0);
-let (count2, set_count2) = create_signal(cx, 0);
-let a = create_resource(cx, count, |count| async move { load_a(count).await });
-let b = create_resource(cx, count2, |count| async move { load_b(count).await });
-
-view! { cx,
-	<h1>"My Data"</h1>
-	{move || match (a.read(cx), b.read(cx)) {
-		_ => view! { cx, <p>"Loading..."</p> }.into_view(cx),
-		(Some(a), Some(b)) => view! { cx,
-			<ShowA a/>
-			<ShowA b/>
-		}.into_view(cx)
-	}}
-}
-```
-
-That’s not _so_ bad, but it’s kind of annoying. What if we could invert the flow of control?
-
-The [`<Suspense/>`](https://docs.rs/leptos/latest/leptos/fn.Suspense.html) component lets us do exactly that. You give it a `fallback` prop and children, one or more of which usually involves reading from a resource. Reading from a resource “under” a `<Suspense/>` (i.e., in one of its children) registers that resource with the `<Suspense/>`. If it’s still waiting for resources to load, it shows the `fallback`. When they’ve all loaded, it shows the children.
-
-```rust
-let (count, set_count) = create_signal(cx, 0);
-let (count2, set_count2) = create_signal(cx, 0);
-let a = create_resource(cx, count, |count| async move { load_a(count).await });
-let b = create_resource(cx, count2, |count| async move { load_b(count).await });
-
-view! { cx,
-	<h1>"My Data"</h1>
-	<Suspense
-		fallback=move || view! { cx, <p>"Loading..."</p> }
-	>
-		<h2>"My Data"</h2>
-		<h3>"A"</h3>
-		{move || {
-			a.read(cx)
-				.map(|a| view! { cx, <ShowA a/> })
-		}}
-		<h3>"B"</h3>
-		{move || {
-			b.read(cx)
-				.map(|b| view! { cx, <ShowB b/> })
-		}}
-	</Suspense>
-}
-```
-
-Every time one of the resources is reloading, the `"Loading..."` fallback will show again.
-
-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.

-# `<Transition/>`
-
-You’ll notice in the `<Suspense/>` example that if you keep reloading the data, it keeps flickering back to `"Loading..."`. Sometimes this is fine. For other times, there’s [`<Transition/>`](https://docs.rs/leptos/latest/leptos/fn.Suspense.html).
-
-`<Transition/>` behaves exactly the same as `<Suspense/>`, but instead of falling back every time, it only shows the fallback the first time. On all subsequent loads, it continues showing the old data until the new data are ready. This can be really handy to prevent the flickering effect, and to allow users to continue interacting with your application.
-
-This example shows how you can create a simple tabbed contact list with `<Transition/>`. When you select a new tab, it continues showing the current contact until the new data laods. This can be a much better user experience than constantly falling back to a loading message.

-# Working with `async`

-So far we’ve only been working with synchronous users interfaces: You provide some input,
-the app immediately process it and updates the interface. This is great, but is a tiny
-subset of what web applications do. In particular, most web apps have to deal with some kind
-of asynchronous data loading, usually loading something from an API.

-Asynchronous data is notoriously hard to integrate with the synchronous parts of your code.
-In this chapter, we’ll see how Leptos helps smooth out that process for you.

-# Server-Side Rendering Modes
-
-This example shows the different "rendering modes" that can be used while server-side 
-rendering an application:
-1. **Synchronous**: Serve an HTML shell that includes `fallback` for any `Suspense`. Load data on the client, replacing `fallback` once they're loaded.
-     - *Pros*: App shell appears very quickly: great TTFB (time to first byte).
-     - *Cons*: Resources load relatively slowly; you need to wait for JS + Wasm to load before even making a request.
- 2. **Out-of-order streaming**: Serve an HTML shell that includes `fallback` for any `Suspense`. Load data on the **server**, streaming it down to the client as it resolves, and streaming down HTML for `Suspense` nodes.
-     - *Pros*: Combines the best of **synchronous** and **`async`**, with a very fast shell and resources that begin loading on the server.
-     - *Cons*: Requires JS for suspended fragments to appear in correct order. Weaker meta tag support when it depends on data that's under suspense (has already streamed down `<head>`)
- 3. **In-order streaming**: Walk through the tree, returning HTML synchronously as in synchronous rendering and out-of-order streaming until you hit a `Suspense`. At that point, wait for all its data to load, then render it, then the rest of the tree.
-     - *Pros*: Does not require JS for HTML to appear in correct order.
-     - *Cons*: Loads the shell more slowly than out-of-order streaming or synchronous rendering because it needs to pause at every `Suspense`. Cannot begin hydration until the entire page has loaded, so earlier pieces
-       of the page will not be interactive until the suspended chunks have loaded.
- 4. **`async`**: Load all resources on the server. Wait until all data are loaded, and render HTML in one sweep.
-     - *Pros*: Better handling for meta tags (because you know async data even before you render the `<head>`). Faster complete load than **synchronous** because async resources begin loading on server.
-     - *Cons*: Slower load time/TTFB: you need to wait for all async resources to load before displaying anything on the client.
-
-## Server Side Rendering with `cargo-leptos`
-`cargo-leptos` is now the easiest and most featureful way to build server side rendered apps with hydration. It provides automatic recompilation of client and server code, wasm optimisation, CSS minification, and more! Check out more about it [here](https://github.com/akesson/cargo-leptos)
-
-1. Install cargo-leptos
-```bash
-cargo install --locked cargo-leptos
-``` 
-2. Build the site in watch mode, recompiling on file changes
-```bash
-cargo leptos watch
-```
-
-Open browser on [http://localhost:3000/](http://localhost:3000/)
-
-3. When ready to deploy, run
-```bash
-cargo leptos build --release
-```
-
-## Server Side Rendering without cargo-leptos
-To run it as a server side app with hydration, you'll need to have wasm-pack installed.
-
-0. Edit the `[package.metadata.leptos]` section and set `site-root` to `"."`. You'll also want to change the path of the `<StyleSheet / >` component in the root component to point towards the CSS file in the root. This tells leptos that the WASM/JS files generated by wasm-pack are available at `./pkg` and that the CSS files are no longer processed by cargo-leptos. Building to alternative folders is not supported at this time. You'll also want to edit the call to `get_configuration()` to pass in `Some(Cargo.toml)`, so that Leptos will read the settings instead of cargo-leptos. If you do so, your file/folder names cannot include dashes.
-1. Install wasm-pack
-```bash
-cargo install wasm-pack
-```
-2. Build the Webassembly used to hydrate the HTML from the server
-```bash
-wasm-pack build --target=web --debug --no-default-features --features=hydrate
-```
-3. Run the server to serve the Webassembly, JS, and HTML 
-```bash
-cargo run --no-default-features --features=ssr
-```

-# Leptos Todo App Sqlite with Viz
-
-This example creates a basic todo app with a Viz backend that uses Leptos' server functions to call sqlx from the client and seamlessly run it on the server.
-
-## Client Side Rendering
-This example cannot be built as a trunk standalone CSR-only app. Only the server may directly connect to the database.
-
-## Server Side Rendering with cargo-leptos
-cargo-leptos is now the easiest and most featureful way to build server side rendered apps with hydration. It provides automatic recompilation of client and server code, wasm optimisation, CSS minification, and more! Check out more about it [here](https://github.com/akesson/cargo-leptos)
-
-1. Install cargo-leptos
-```bash
-cargo install --locked cargo-leptos
-``` 
-2. Build the site in watch mode, recompiling on file changes
-```bash
-cargo leptos watch
-```
-
-Open browser on [http://localhost:3000/](http://localhost:3000/)
-
-3. When ready to deploy, run
-```bash
-cargo leptos build --release
-```
-
-## Server Side Rendering without cargo-leptos
-To run it as a server side app with hydration, you'll need to have wasm-pack installed.
-
-0. Edit the `[package.metadata.leptos]` section and set `site-root` to `"."`. You'll also want to change the path of the `<StyleSheet / >` component in the root component to point towards the CSS file in the root. This tells leptos that the WASM/JS files generated by wasm-pack are available at `./pkg` and that the CSS files are no longer processed by cargo-leptos. Building to alternative folders is not supported at this time. You'll also want to edit the call to `get_configuration()` to pass in `Some(Cargo.toml)`, so that Leptos will read the settings instead of cargo-leptos. If you do so, your file/folder names cannot include dashes.
-1. Install wasm-pack
-```bash
-cargo install wasm-pack
-```
-2. Build the Webassembly used to hydrate the HTML from the server
-```bash
-wasm-pack build --target=web --debug --no-default-features --features=hydrate
-```
-3. Run the server to serve the Webassembly, JS, and HTML 
-```bash
-cargo run --no-default-features --features=ssr
-```

-/// ## Core Trait Implementations
-/// - [`.get()`](#impl-SignalGet<T>-for-Memo<T>) (or calling the signal as a function) clones the current
-///   value of the signal. If you call it within an effect, it will cause that effect
-///   to subscribe to the signal, and to re-run whenever the value of the signal changes.
-///   - [`.get_untracked()`](#impl-SignalGetUntracked<T>-for-Memo<T>) clones the value of the signal
-///   without reactively tracking it.
-/// - [`.with()`](#impl-SignalWith<T>-for-Memo<T>) allows you to reactively access the signal’s value without
-///   cloning by applying a callback function.
-///   - [`.with_untracked()`](#impl-SignalWithUntracked<T>-for-Memo<T>) allows you to access the signal’s
-///   value without reactively tracking it.
-/// - [`.to_stream()`](#impl-SignalStream<T>-for-Memo<T>) converts the signal to an `async` stream of values.
-///
