## Overview
|
|
|
|
`dioxus-hooks` includes some basic useful hooks for Dioxus such as:
|
|
|
|
- use_signal
|
|
- use_effect
|
|
- use_resource
|
|
- use_memo
|
|
- use_coroutine
|
|
|
|
Unlike React, none of these hooks are foundational since they all build off the primitive `use_hook`. You can extend these hooks with [custom hooks](https://dioxuslabs.com/learn/0.5/cookbook/state/custom_hooks) in your own code. If you think they would be useful for the broader community, you can open a PR to add your hook to the [Dioxus Awesome](https://github.com/DioxusLabs/awesome-dioxus) list.
|

|
|
## State Cheat Sheet
|
|
|
|
If you aren't sure what hook to use, you can use this cheat sheet to help you decide:
|
|
|
|
### State Location
|
|
|
|
Depending on where you need to access the state, you can put your state in one of three places:
|
|
|
|
| Location | Where can you access the state? | Recommended for Libraries? | Examples |
|
|
| ---------------------------------------------------------------------------------------- | ------------------------------- | -------------------------- | --------------------------------------------------------------------------- |
|
|
| [Hooks](https://docs.rs/dioxus-hooks/latest/dioxus_hooks/fn.use_signal.html) | Any components you pass it to | ✅ | `use_signal(\|\| 0)`, `use_memo(\|\| state() * 2)` |
|
|
| [Context](https://docs.rs/dioxus-hooks/latest/dioxus_hooks/fn.use_context_provider.html) | Any child components | ✅ | `use_context_provider(\|\| Signal::new(0))`, `use_context::<Signal<i32>>()` |
|
|
| [Global](https://docs.rs/dioxus/latest/dioxus/prelude/struct.Signal.html#method.global) | Anything in your app | ❌ | `Signal::global(\|\| 0)` |
|
|
|
|
### Derived State
|
|
|
|
If you don't have an initial value for your state, you can derive your state from other states with a closure or asynchronous function:
|
|
|
|
| Hook | Reactive (reruns when dependencies change) | Async | Memorizes Output | Example |
|
|
| ----------------------------------------------------------------------------------- | ------------------------------------------ | ----- | ---------------- | ----------------------------------------------------------------------------------- |
|
|
| [`use_memo`](https://docs.rs/dioxus/latest/dioxus/prelude/fn.use_memo.html) | ✅ | ❌ | ✅ | `use_memo(move \|\| count() * 2)` |
|
|
| [`use_resource`](https://docs.rs/dioxus/latest/dioxus/prelude/fn.use_resource.html) | ✅ | ✅ | ❌ | `use_resource(move \|\| reqwest::get(format!("/users/{user_id}")))` |
|
|
| [`use_future`](https://docs.rs/dioxus/latest/dioxus/prelude/fn.use_future.html) | ❌ | ✅ | ❌ | `use_future(move \|\| println!("{:?}", reqwest::get(format!("/users/{user_id}"))))` |
|
|
|
|
### Persistent State
|
|
|
|
The core hooks library doesn't provide hooks for persistent state, but you can extend the core hooks with hooks from [dioxus-sdk](https://crates.io/crates/dioxus-sdk) and the [dioxus-router](https://crates.io/crates/dioxus-router) to provide persistent state management.
|
|
|
|
| State | Sharable | Example |
|
|
| ---------------------------------------------------------------------------------- | -------- | ------------------------------------------------------------------------------------------------- |
|
|
| [`use_persistent`](https://github.com/DioxusLabs/sdk/tree/master/examples/storage) | ❌ | `use_persistent("unique_key", move \|\| initial_state)` |
|
|
| [`Router<Route> {}`](https://dioxuslabs.com/learn/0.5/router) | ✅ | `#[derive(Routable, Clone, PartialEq)] enum Route { #[route("/user/:id")] Homepage { id: u32 } }` |
