# Parity with React

## Required services:

---

Gloo is covering a lot of these. We want to build hooks around these and provide examples on how to use them.
https://github.com/rustwasm/gloo

For example, resize observer would function like this:

```rust
static Example: FC<()> = |cx| {
    let observer = use_resize_observer();

    cx.render(rsx!(
        div { ref: observer.node_ref
            "Size, x: {observer.x} y: {observer.y}"
        }
    ))
}
```

However, resize observing is _not_ cross-platform, so this hook (internally) needs to abstract over the rendering platform.

For other services, we shell out to gloo. If the gloo service doesn't exist, then we need to contribute to the project to make sure it exists.
