Dioxus Hooks
Website | Guides | API Docs | Chat
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 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 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 | Any components you pass it to | ✅ | use_signal(|| 0), use_memo(|| state() * 2) |
| Context | Any child components | ✅ | use_context_provider(|| Signal::new(0)), use_context::<Signal<i32>>() |
| 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 |
✅ | ❌ | ✅ | use_memo(move || count() * 2) |
use_resource |
✅ | ✅ | ❌ | use_resource(move || reqwest::get(format!("/users/{user_id}"))) |
use_future |
❌ | ✅ | ❌ | 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 and the dioxus-router to provide persistent state management.
| State | Sharable | Example |
|---|---|---|
use_persistent |
❌ | use_persistent("unique_key", move || initial_state) |
Router<Route> {} |
✅ | #[derive(Routable, Clone, PartialEq)] enum Route { #[route("/user/:id")] Homepage { id: u32 } } |
