use-state-vue

Simple replica of React useState() and useReducer() for Vue 3.

Install

npm install use-state-vue

Usage

useState()

import { useState } from 'use-state-vue';

const [count, setCount] = useState(0);

setCount(count + 1);

useReducer()

import { useReducer } from 'use-state-vue';

const initialState = { count: 0 };

function reducer(state, action) {
  switch (action.type) {
    case 'increment':
      return { count: state.count + 1 };
    case 'decrement':
      return { count: state.count - 1 };
    default:
      throw new Error('Action not implemented');
  }
};

const [state, dispatch] = useReducer(reducer, initialState);

dispatch({ type: 'increment' });

Idea behind this library

This library tries to replicate the useState() hook present in React.

The equivalent in Vue 3 is something like:

import { ref } from 'vue';

const count = ref(0);

const increment = () => {
  count.value += 1;
};
