```rust
use leptos::*;
use leptos_use::{use_mouse, UseMouseReturn};

#[component]
fn Demo() -> impl IntoView {
    let UseMouseReturn { x, y, .. } = use_mouse();
    
    view! { cx,
        {x} " x " {y}
    }
}

## Development

To run all tests run

```shell
cargo test --all-features
```

### Book

First you need to install

```shell
cargo install mdbook mdbook-cmdrun trunk
```

To build the book go in your terminal into the docs/book folder
and run

```shell
mdbook serve
```

This builds the html version of the book and runs a local dev server.
To also add in the examples open another shell and run

```shell
python3 post_build.py
```

If you only want to add the example for one function you can run for example

```shell
python3 post_build.py use_storage
```

### New Function Template

To scaffold a new function quickly you can run `template/createfn.sh`. It requires that [`ffizer`](https://ffizer.github.io/) and Python 3 is installed.
This will create the function file in the src directory, scaffold an example directory and an entry in the book.
