-----
Fermi is a global state management solution for Dioxus that's as easy as `use_state`.
Inspired by atom-based state management solutions, all state in Fermi starts as an `atom`:
```rust
static NAME: Atom<&str> = |_| "Dioxus";
```
From anywhere in our app, we can read our the value of our atom:
```rust
fn NameCard(cx: Scope) -> Element {
let name = use_read(&cx, NAME);
cx.render(rsx!{ h1 { "Hello, {name}"} })
}
```
We can also set the value of our atom, also from anywhere in our app:
```rust
fn NameCard(cx: Scope) -> Element {
let set_name = use_set(&cx, NAME);
cx.render(rsx!{
button {
onclick: move |_| set_name("Fermi"),
"Set name to fermi"
}
})
}
```
It's that simple!
## Installation
Fermi is currently under construction, so you have to use the `master` branch to get started.
```rust
[depdencies]
fermi = { git = "https://github.com/dioxuslabs/fermi" }
```
## Running examples
The examples here use Dioxus Desktop to showcase their functionality. To run an example, use
```
$ cargo run --example EXAMPLE
```
## Features
Broadly our feature set to required to be released includes:
- [x] Support for Atoms
- [x] Support for AtomRef (for values that aren't clone)
- [ ] Support for Atom Families
- [ ] Support for memoized Selectors
- [ ] Support for memoized SelectorFamilies
- [ ] Support for UseFermiCallback for access to fermi from async
