Question 1

How to install Yew Hooks in a Yew project?

Accepted Answer

Add 'yew-hooks' to your Cargo.toml dependencies, then import hooks from yew_hooks::prelude::* in your Rust files. The README shows basic setup with use_counter examples, and you can refer to the docs.rs for detailed configuration.

Question 2

Yew Hooks vs Yew's built-in hooks – which should I use?

Accepted Answer

Yew Hooks extends Yew's basic hooks with more utilities like use_websocket and use_theme, but if you only need simple state management, Yew's use_state might suffice. Yew Hooks is better for complex apps needing React-like patterns, but it adds an extra dependency.

Question 3

How to handle data fetching with Yew Hooks use_async?

Accepted Answer

Use use_async with an async function, like fetching from an API, as shown in the README example with GitHub repos. It manages loading, error, and data states, and you can trigger runs via callbacks or effects for declarative side effects.

Question 4

Does Yew Hooks support server-side rendering with Yew?

Accepted Answer

The README doesn't mention server-side rendering explicitly, and hooks like use_local_storage are client-specific. For SSR, you might need to handle hydration carefully or use Yew's SSR features separately, as hooks may not work seamlessly on the server.

Question 5

What's the performance impact of Yew Hooks on WebAssembly apps?

Accepted Answer

Hooks add minimal runtime overhead due to Rust's efficiency, but hooks like use_virtual_list can improve performance for large UIs. However, unnecessary hook usage might increase bundle size, so profile your app to balance features and speed.

Question 6

How to contribute to Yew Hooks or request new hooks?

Accepted Answer

Check the GitHub repo's issues for current needs or open a PR; the README encourages contributions. You can propose hooks based on React equivalents or missing features, but be prepared for Rust-specific implementation challenges.
