Dioxus - Use Request Hook

A small crate that adds a hook for simple GET requests and convienient macro to Dioxus.

Example

Function

Using the hook like this...

let dog = use_request(&cx, (breed,), format!("https://dog.ceo/api/breed/{breed}/images/random"));

cx.render(match dog {
    Success(val) => rsx!(img { src: "{val.message}"}}),
    Failure(err) => rsx!("Failed to load dog"),
    Loading => rsx!("Loading dog image!"),
})

...achieves the same as this snippet which uses the Use Future Hook:

let dog = use_future(&cx, (breed,), |(breed)| async move {
        reqwest::get(format!("https://dog.ceo/api/breed/{breed}/images/random"))
            .await
            .unwrap()
            .json::<RandomDog>()
            .await
    });
    
cx.render(match dog.value() {
    Some(Ok(val)) => rsx!(img { src: "{val.message}"}}),
    Some(Err(err)) => rsx!("Failed to load dog"),
    None => rsx!("Loading dog image!"),
})

Macro

For additional convienience, you can also enable the use_request! macro.

[dependencies]
dioxus-use-request = { version = "0.1.4", features = ["macro"] }

It automatically extract the hook's dependencies from the given URL string. Using the macro, the example from above looks like this:

// Macro automatically extracts dependencies in curly braces (e.g. {breed}) from the given string literal
let dog = use_request!(cx, "https://dog.ceo/api/breed/{breed}/images/random");

cx.render(match dog {
    Success(val) => rsx!(img { src: "{val.message}"}}),
    Failure(err) => rsx!("Failed to load dog"),
    Loading => rsx!("Loading dog image!"),
})

Installation

For instructions on getting started with Dioxus, please refer to their Getting Started Guide. To use this crate, simply add it as dependency in your Cargo.toml. Make sure to enable the "macro" feature if you want to use the use_request! macro:
