Welcome to the Comprehensive Guide to use-global-hook

Managing global state in React applications can be challenging and sometimes confusing.
The use-global-hook library is a powerful tool that simplifies state
management by leveraging hooks. This guide will help you understand use-global-hook
and provide you with useful examples to get started.

Introduction to use-global-hook

The use-global-hook library is a lightweight state management solution for
React applications using hooks. It allows sharing state and actions across components
without the need for additional boilerplate code.

Getting Started

To install use-global-hook, run the following command:

  
    npm install use-global-hook
  

Creating a Global Store

First, create a global store with initial state and actions:

  
    import React from 'react';
    import useGlobalHook from 'use-global-hook';

    const initialState = {
      counter: 0,
      user: 'Guest'
    };

    const actions = {
      increment: (store) => {
        const [state, setState] = store;
        setState({ counter: state.counter + 1 });
      },
      setUser: (store, user) => {
        const [state, setState] = store;
        setState({ user });
      },
      reset: (store) => {
        setState(initialState);
      }
    };

    const useGlobal = useGlobalHook(React, initialState, actions);

    export default useGlobal;
  

Using the Global Store in Components

You can now use the global store in your components:

  
    import React from 'react';
    import useGlobal from './useGlobal';

    const Counter = () => {
      const [globalState, globalActions] = useGlobal();

      return (
        <div>
          <p>Counter: {globalState.counter}</p>
          <button onClick={globalActions.increment}>Increment</button>
        </div>
      );
    };

    export default Counter;
  

Another Component Using the Store

Here’s another component that uses the global store to manage user state:

  
    import React, { useState } from 'react';
    import useGlobal from './useGlobal';

    const UserManager = () => {
      const [globalState, globalActions] = useGlobal();
      const [userName, setUserName] = useState('');

      return (
        <div>
          <p>Current User: {globalState.user}</p>
          <input
            value={userName}
            onChange={(e) => setUserName(e.target.value)}
            placeholder="Enter user name"
          />
          <button onClick={() => globalActions.setUser(userName)}>Set User</button>
        </div>
      );
    };

    export default UserManager;
  

Combining Components

Finally, you can combine these components to create a fully functional application:

  
    import React from 'react';
    import Counter from './Counter';
    import UserManager from './UserManager';

    const App = () => {
      return (
        <div>
          <Counter />
          <UserManager />
        </div>
      );
    };

    export default App;
  

With these examples, you can now manage global state in your React applications
efficiently using the use-global-hook library. Happy coding!
