### Use WebSocket Hook Example

Source: https://github.com/jetli/yew-hooks/blob/main/README.md

Demonstrates the `use_websocket` hook for establishing and managing WebSocket connections. It includes sending messages, receiving messages, and updating a message history list. The example uses Rust and the Yew framework.

```rust
use yew::prelude::*;
use yew_hooks::prelude::*;

#[function_component(UseWebSocket)]
pub fn web_socket() -> Html {
    let history = use_list(vec![]);
    let ws = use_websocket("wss://echo.websocket.events/".to_string());

    let onclick = {
        let ws = ws.clone();
        let history = history.clone();
        Callback::from(move |_| {
            let message = "Hello, world!".to_string();
            ws.send(message.clone());
            history.push(format!("[send]: {}", message));
        })
    };

    {
        let history = history.clone();
        let ws = ws.clone();
        use_effect_with(
            ws.message,
            move |message| {
                if let Some(message) = &**message {
                    history.push(format!("[recv]: {}", message.clone()));
                }
                || ()
            },
        );
    }

    html! {
        <div>
            <p>
                <button {onclick} disabled={*ws.ready_state != UseWebSocketReadyState::Open}>{ "Send" }</button>
            </p>
            <p>
                <b>{ "Message history: " }</b>
            </p>
            {
                for history.current().iter().map(|message| {
                    html! {
                        <p>{ message }</p>
                    }
                })
            }
        </div>
    }
}

```

### Use Async Hook Example

Source: https://github.com/jetli/yew-hooks/blob/main/README.md

Demonstrates the usage of the `use_async` hook for asynchronous operations, such as fetching data from an API. It includes handling loading states, displaying fetched data, and managing errors. The example uses Rust and the Yew framework.

```rust
use serde::{de::DeserializeOwned, Deserialize, Serialize};
use yew::prelude::*;
use yew_hooks::prelude::*;

#[function_component(UseAsync)]
pub fn async_demo() -> Html {
    let state = use_async(async move { fetch_repo("jetli/yew-hooks".to_string()).await });

    let onclick = {
        let state = state.clone();
        Callback::from(move |_| {
            // You can trigger to run in callback or use_effect.
            state.run();
        })
    };

    html! {
        <div>
            <button {onclick} disabled={state.loading}>{ "Start to load repo: jetli/yew-hooks" }</button>
            <p>
                { 
                    if state.loading {
                        html! { "Loading, wait a sec..." }
                    } else {
                        html! {}
                    }
                }
            </p>
            {
                if let Some(repo) = &state.data {
                    html! {
                        <>
                            <p>{ "Repo name: " }<b>{ &repo.name }</b></p>
                            <p>{ "Repo full name: " }<b>{ &repo.full_name }</b></p>
                            <p>{ "Repo description: " }<b>{ &repo.description }</b></p>

                            <p>{ "Owner name: " }<b>{ &repo.owner.login }</b></p>
                            <p>{ "Owner avatar: " }<b><br/><img alt="avatar" src={repo.owner.avatar_url.clone()} /></b></p>
                        </>
                        }
                } else {
                    html! {}
                }
            }
            <p>
                {
                    if let Some(error) = &state.error {
                        match error {
                            Error::DeserializeError => html! { "DeserializeError" },
                            Error::RequestError => html! { "RequestError" },
                        }
                    } else {
                        html! {}
                    }
                }
            </p>
        </div>
    }
}

async fn fetch_repo(repo: String) -> Result<Repo, Error> {
    fetch::<Repo>(format!("https://api.github.com/repos/{}", repo)).await
}

/// You can use reqwest or other crates to fetch your api.
async fn fetch<T>(url: String) -> Result<T, Error>
where
    T: DeserializeOwned,
{
    let response = reqwest::get(url).await;
    if let Ok(data) = response {
        if let Ok(repo) = data.json::<T>().await {
            Ok(repo)
        } else {
            Err(Error::DeserializeError)
        }
    } else {
        Err(Error::RequestError)
    }
}

#[derive(Serialize, Deserialize, Clone, Debug, PartialEq)]
struct User {
    id: i32,
    login: String,
    avatar_url: String,
}

#[derive(Serialize, Deserialize, Clone, Debug, PartialEq)]
struct Repo {
    id: i32,
    name: String,
    full_name: String,
    description: String,
    owner: User,
}

// You can use thiserror to define your errors.
#[derive(Clone, Debug, PartialEq)]

    RequestError,
    DeserializeError,
    // etc.
}

### Counter Hook Example

Source: https://github.com/jetli/yew-hooks/blob/main/README.md

Demonstrates the usage of the `use_counter` hook to manage a simple counter state within a Yew functional component. It includes buttons to increase and decrease the counter value.

```rust
use yew_hooks::prelude::*;

#[function_component(Counter)]
fn counter() -> Html {
    let counter = use_counter(0);

    let onincrease = {
        let counter = counter.clone();
        Callback::from(move |_| counter.increase())
    };
    let ondecrease = {
        let counter = counter.clone();
        Callback::from(move |_| counter.decrease())
    };

    html! {
        <>
            <button onclick={onincrease}>{ "Increase" }</button>
            <button onclick={ondecrease}>{ "Decrease" }</button>
            <b>{ "Current value: " }</b>
            { *counter }
        </>
    }
}
```

### use_counter Demo

Source: https://github.com/jetli/yew-hooks/blob/main/README.md

Demonstrates the usage of the `use_counter` hook in Yew. It shows how to initialize a counter, increment, decrement, set, and reset its value using callbacks.

```rust
use yew::prelude::*;
use yew_hooks::prelude::*;

#[function_component(Counter)]
fn counter() -> Html {
    let counter = use_counter(0);

    let onincrease = {
        let counter = counter.clone();
        Callback::from(move |_| counter.increase())
    };
    let ondecrease = {
        let counter = counter.clone();
        Callback::from(move |_| counter.decrease())
    };
    let onincreaseby = {
        let counter = counter.clone();
        Callback::from(move |_| counter.increase_by(10))
    };
    let ondecreaseby = {
        let counter = counter.clone();
        Callback::from(move |_| counter.decrease_by(10))
    };
    let onset = {
        let counter = counter.clone();
        Callback::from(move |_| counter.set(100))
    };
    let onreset = {
        let counter = counter.clone();
        Callback::from(move |_| counter.reset())
    };

    html! {
        <div>
            <button onclick={onincrease}>{ "Increase" }</button>
            <button onclick={ondecrease}>{ "Decrease" }</button>
            <button onclick={onincreaseby}>{ "Increase by 10" }</button>
            <button onclick={ondecreaseby}>{ "Decrease by 10" }</button>
            <button onclick={onset}>{ "Set to 100" }</button>
            <button onclick={onreset}>{ "Reset" }</button>
            <p>
                <b>{ "Current value: " }</b>
                { *counter }
            </p>
        </div>
    }
}
```

### Build in Release Mode

Source: https://github.com/jetli/yew-hooks/blob/main/examples/yew-app/README.md

Compiles the Yew project for production, outputting the build artifacts into the 'dist' folder. This is used for deploying the application.

```sh
trunk build
# Builds the project and places it into the `dist` folder.
```

--------------------------------

### Run in Debug Mode

Source: https://github.com/jetli/yew-hooks/blob/main/examples/yew-app/README.md

Builds the Yew project and serves it in a new browser tab, with automatic reloading on file changes. This command is used for development and debugging.

```sh
trunk serve
# Builds the project and opens it in a new browser tab. Auto-reloads when the project changes.
```

--------------------------------

### Run Unit Tests

Source: https://github.com/jetli/yew-hooks/blob/main/examples/yew-app/README.md

Executes the unit tests for the Yew project in a headless Chrome environment. This command is crucial for ensuring code quality and correctness.

```sh
wasm-pack test --headless --chrome
# Runs tests
```
