## Sending Values
You might've noticed the `use_coroutine` closure takes an argument called `rx`. What is that? Well, a common pattern in complex apps is to handle a bunch of async code at once. With libraries like Redux Toolkit, managing multiple promises at once can be challenging and a common source of bugs.
-With Coroutines, we have the opportunity to centralize our async logic. The `rx` parameter is an Unbounded Channel for code external to the coroutine to send data *into* the coroutine. Instead of looping on an external service, we can loop on the channel itself, processing messages from within our app without needing to spawn a new future. To send data into the coroutine, we would call "send" on the handle.

+Dioxus is built around the concept of [Templates](https://docs.rs/dioxus-core/latest/dioxus_core/prelude/struct.Template.html). Templates describe a UI tree known at compile time with dynamic parts filled at runtime. This is useful internally to make skip diffing static nodes, but it is also useful for the renderer to reuse parts of the UI tree. This can be useful for things like a list of items. Each item could contain some static parts and some dynamic parts. The renderer can use the template to create a static part of the UI once, clone it for each element in the list, and then fill in the dynamic parts.

Additionally, these edits are serializable, meaning we can even manage UIs across a network connection. This little stack machine and serialized edits make Dioxus independent of platform specifics.
Dioxus is also really fast. Because Dioxus splits the diff and patch phase, it's able to make all the edits to the RealDOM in a very short amount of time (less than a single frame) making rendering very snappy. It also allows Dioxus to cancel large diffing operations if higher priority work comes in while it's diffing.
It's important to note that there _is_ one layer of connectedness between Dioxus and the renderer. Dioxus saves and loads elements (the PushRoot edit) with an ID. Inside the VirtualDOM, this is just tracked as a u64.
-Whenever a `CreateElement` edit is generated during diffing, Dioxus increments its node counter and assigns that new element its current NodeCount. The RealDom is responsible for remembering this ID and pushing the correct node when PushRoot(ID) is generated. Dioxus reclaims IDs of elements when removed. To stay in sync with Dioxus you can use a sparce Vec (Vec>) with possibly unoccupied items. You can use the ids as indexes into the Vec for elements, and grow the Vec when a id does not exist.

+### Attributes
+
+Attributes (and [listeners](../interactivity/index.md)) modify the behavior or appearance of the element they are attached to. They are specified inside the `{}` brackets, using the `name: value` syntax. You can provide the value as a literal in the RSX:
+```rust

Build a standalone native desktop app that looks and feels the same across operating systems.
Apps built with Dioxus are typically <5mb in size and use existing system resources, so they won't hog extreme amounts of RAM or memory.

## Support
-The desktop is a powerful target for Dioxus, but is currently limited in capability when compared to the Web platform. Currently, desktop apps are rendered with the platform's WebView library, but your Rust code is running natively on a native thread. This means that browser APIs are *not* available, so rendering WebGL, Canvas, etc is not as easy as the Web. However, native system APIs *are* accessible, so streaming, WebSockets, filesystem, etc are all viable APIs. In the future, we plan to move to a custom webrenderer-based DOM renderer with WGPU integrations.

In the future, we plan to move to a custom web renderer-based DOM renderer with WGPU integrations.
Dioxus Desktop is built off [Tauri](https://tauri.app/). Right now there aren't any Dioxus abstractions over keyboard shortcuts, menubar, handling, etc, so you'll want to leverage Tauri – mostly [Wry](http://github.com/tauri-apps/wry/) and [Tao](http://github.com/tauri-apps/tao)) directly.
+# Getting started
+
+## Platform-Specific Dependencies
+Dioxus desktop renders through a web view. Depending on your platform, you might need to install some dependancies.
+
+### Windows
+
+Windows Desktop apps depend on WebView2 – a library that should be installed in all modern Windows distributions. If you have Edge installed, then Dioxus will work fine. If you *don't* have Webview2, [then you can install it through Microsoft](https://developer.microsoft.com/en-us/microsoft-edge/webview2/). MS provides 3 options:
+
+1. A tiny "evergreen" *bootstrapper* that fetches an installer from Microsoft's CDN
+2. A tiny *installer* that fetches Webview2 from Microsoft's CDN
+3. A statically linked version of Webview2 in your final binary for offline users
+
+For development purposes, use Option 1.
+
+### Linux
+
+Webview Linux apps require WebkitGtk. When distributing, this can be part of your dependency tree in your `.rpm` or `.deb`. However, likely, your users will already have WebkitGtk.
+
+```bash
+sudo apt install libwebkit2gtk-4.0-dev libgtk-3-dev libappindicator3-dev
+```
+
+When using Debian/bullseye `libappindicator3-dev` is no longer available but replaced by `libayatana-appindicator3-dev`.
+
+```bash
+# on Debian/bullseye use:
+sudo apt install libwebkit2gtk-4.0-dev libgtk-3-dev libayatana-appindicator3-dev
+```
+
+If you run into issues, make sure you have all the basics installed, as outlined in the [Tauri docs](https://tauri.studio/v1/guides/getting-started/prerequisites#setting-up-linux).
+
+
+### MacOS
+
+Currently – everything for macOS is built right in! However, you might run into an issue if you're using nightly Rust due to some permissions issues in our Tao dependency (which have been resolved but not published).

+Liveview allows apps to *run* on the server and *render* in the browser. It uses WebSockets to communicate between the server and the browser.
+
+Examples:
+- [Axum Example](https://github.com/DioxusLabs/dioxus/tree/master/packages/liveview/examples/axum.rs)
+- [Salvo Example](https://github.com/DioxusLabs/dioxus/tree/master/packages/liveview/examples/salvo.rs)
+- [Warp Example](https://github.com/DioxusLabs/dioxus/tree/master/packages/liveview/examples/warp.rs)
+
+
+## Support
+
+Liveview is currently limited in capability when compared to the Web platform. Liveview apps run on the server in a native thread. This means that browser APIs are not available, so rendering WebGL, Canvas, etc is not as easy as the Web. However, native system APIs are accessible, so streaming, WebSockets, filesystem, etc are all viable APIs.
+
+
+## Setup
+
+For this guide, we're going to show how to use Dioxus Liveview with [Axum](https://docs.rs/axum/latest/axum/).
+
+Make sure you have Rust and Cargo installed, and then create a new project:
+
+```shell
+cargo new --bin demo
+cd app
+```
+
+Add Dioxus and the liveview renderer with the Axum feature as dependencies:
+
+```shell
+cargo add dioxus
+cargo add dioxus-liveview --features axum
+```
+
+Next, add all the Axum dependencies. This will be different if you're using a different Web Framework
+
+```
+cargo add tokio --features full
+cargo add axum
+```
+
+Your dependencies should look roughly like this:
+
+```toml
+[dependencies]
+axum = "0.4.5"
+dioxus = { version = "*" }
+dioxus-liveview = { version = "*", features = ["axum"] }
+tokio = { version = "1.15.0", features = ["full"] }
+```
+
+Now, set up your Axum app to respond on an endpoint.
+
+
+```rust
+{{#include ../../../examples/hello_world_liveview.rs:glue}}
+```
+
+
+And then add our app component:
+
+```rust
+{{#include ../../../examples/hello_world_liveview.rs:app}}
+```
+
+And that's it!

- Keys should be relatively small (i.e. converting the entire Comment structure to a String would be a pretty bad key) so they can be compared efficiently
-You might be tempted to use an item's index in the list as its key. In fact, that’s what Dioxus will use if you don’t specify a key at all. This is only acceptable if you can guarantee that the list is constant – i.e., no re-ordering, additions or deletions.

{{#include ../../../examples/hooks_use_ref.rs:component}}
```
-> The return values of `use_state` and `use_ref`, (`UseState` and `UseRef`, respectively) are in some ways similar to [`Cell`](https://doc.rust-lang.org/std/cell/) and [`RefCell`](https://doc.rust-lang.org/std/cell/struct.RefCell.html) – they provide interior mutability. However, these Dioxus wrappers also ensure that the component gets re-rendered whenever you change the state.

For example, it's harder to keep the input in sync with another element.
Since you don't necessarily have the current value of the uncontrolled input in state, you can access it either by listening to `oninput` events (similarly to controlled components), or, if the input is part of a form, you can access the form data in the form events (e.g. `oninput` or `onsubmit`):
