Use State Global

A really simple react hook for managing shared/global state.

About

Sometimes you might want to manage global application state but don't need something like Redux or Mobx. That's what useStateGlobal is for.

It seamlessly synchronizes state across all components that use it but does not increase your bundle size by that much.

Install

# yarn
yarn add use-state-global

# npm
npm install --save use-state-global

Usage

Basic Hook

import createGlobalState from 'use-state-global';

let useGlobalState = createGlobalState({
  // initial state
  count: 1
});

let Component = () => {
  let [state, setState] = useGlobalState();

  return (
    <div>
      Count: {count}
      <button onClick={() => setState({ count: count + 1 })}>Add 1</button>
    </div>
  );
};

let OtherComponent = () => {
  let [state] = useGlobalState();

  return <div>Same count as the other one: {count}</div>;
};

Accessing state from the outside

import createGlobalState from 'use-state-global';

let useGlobalState = createGlobalState({
  // initial state
  count: 1
});

// Set state from outside
useGlobalState.setState({ count: 5 });

// Get state from outside
console.log(useGlobalState.getState());
// > { count: 5 }

let Component = () => {
  let [state, setState] = useGlobalState();

  return (
    <div>
      Count: {count}
      <button onClick={() => setState({ count: count + 1 })}>Add 1</button>
    </div>
  );
};
