Who doesn’t love Github? It’s home to thousands of developers and open-source projects. To get a better understanding of the power and flexibility of React Hooks, we have 10 React Hooks Example examples from their excellent documentation.

1. React hooks for async communication

React hooks for async communication

exports

The two most important exports of this module are:

Usage:

const [state, setState, getState] = useRefState();

This hook can be used to interact with the current state of the component from a process spawned from an old render cycle.

async () => {
    //...
    const fresh = getState();
    setState(fresh.process());
    //...
}

useFuture

// Sends a message for a render cycle in the future to respond to
export function useFuture<A, B>(): [undefined | ((f: (a: A) => B) => void), (a: A) => Promise<B>];

Usage:

const [respond, message] = useFuture();

This hook can be used to send a message which will force a re-render and will await for a future cycle to respond.

async () => {
    //...
    await message(cycle);
    //...
}
//...
<>
    {/*...*/}
    { respond &&
        <Responder onClick={() => alert(`handled message from cycle: ${respond()}`)} />
    }
    {/*...*/}
</>

6. React hook for logging per component lifecycle

Features

• 🪶 Lightweight — under 1.5 kB gzipped & minified
• 🗂️ Typed — made with TypeScript, shipped with types
• 🥰 Simple — don’t worry about any changes in your props & state
• 🔧 Customizable — able to change everything you see in the logs
• 🔬 Tested — up to 💯% unit test coverage
• 🏎️ Fast — native react hooks & optimized
• 📭 No dependecies

7. React-persist-store

⚡ A persistent state management library for React. Create your own hooks that share data across components

Create your own hooks that share state. Initialise your store with default values and use an API that infers type information for you.

Features

• Persistence: data is serialized and persisted to local storage by default, and hydrated automatically
• Type safety: full TypeScript integration with type inference from default values
• Reactive design: state updates are shared across components
• Simplicity: does not require any component wrapping, or use of other abstractions such as the Context API

Getting Started

At a high level, it is generally suggested to create a store.ts file in which you set up your exported hook functions. Then these can be imported and used in components.
