Vuex - But for React! ⚛

Enjoy the vuex API in your React applications with vuex-but-for-react, which uses only React Context and React use-sync-external-store under the hood.

vuex-but-for-react was engineered with developer experience in mind, making it very easy to use. Invoke your getter or action by using a one-line hook and don't worry about unnecessary renders - without using memo.

Your component will render only when its getter changes - and it doesn't care about the rest of the store!

Working example

store.js

const store = {
  state: {
    posts: []
  },
  mutations: {
    POSTS_SET(state, data) {
      state.posts = data
    }
  },
  actions: {
    async POSTS_FETCH(context) {
      const response = await fetch('https://jsonplaceholder.typicode.com/posts')
      const data = await response.json()
      context.mutations.POSTS_SET(data)
    }
  },
  getters: {
    posts (state) {
      return state.posts
    }
  }
}

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import { withStore } from 'vuex-but-for-react';

import App from './App';
import store from './store';

const AppWithStore = withStore(App, store);

ReactDOM.render(
  <AppWithStore />,
  document.getElementById('root')
);

Posts.js

import React, { useEffect } from 'react';
import { useAction, useGetter } from 'vuex-but-for-react';

const Posts = () => {
  const handleAction = useAction('POSTS_FETCH');
  const posts = useGetter('posts');

  useEffect(() => {
    handleAction();
  }, [handleAction]) // don't worry, it doesn't re-create!
  
  return (
    <ul>
      {posts.map(post => <li key={post.id}>{post.title}</li>)}
    </ul>
  );
}

export default Posts

API

useAction(`actionName`)

An action is used for async data logic, especially API calls. You can dispatch mutations and other actions from within an action.

The function returned by the useAction() hook is never re-created.

import { useAction } from 'vuex-but-for-react';

const PostsPage = () => {
  const handleFetch = useAction('POSTS_FETCH');

  useEffect(() => {
    handleFetch();
  }, [handleFetch])

  return (
    ...
  )
}

useMutation(`actionName`)

A mutation is used for sync data operations. It has access to the current state in order to alter it.

The function returned by the useMutation() hook is never re-created.

import { useMutation } from 'vuex-but-for-react';

const Counter = () => {
  const handleIncrement = useMutation('COUNTER_INCREMENT');
  const handleDecrement = useMutation('COUNTER_DECREMENT');

  return (
    <>
      <button onClick={handleDecrement}>-</button>
      <button onClick={handleIncrement}>+</button>
    </>
  )
}

useGetter(`actionName`)

A getter gives you the current stored value based on your config. It has access to the current state.

The data returned by the useGetter() hook is updated only in case the shallow value changes. An update of one getter value won't trigger the update of another getter value.

import { useGetter } from 'vuex-but-for-react';

const PostsPage = () => {
  const posts = useGetter('posts');

  return (
    <ul>
      {posts.map(post => (
        <li key={post.id}>{post.title}</li>
      ))}
    </ul>
  )
}

withStore(`Component`, `config`)

In order to initialize the global store, wrap your (chosen) root component in your store config.

import { withStore } from 'vuex-but-for-react';

const AppWithStore = withStore(App, store);

And more amazing stuff!

useActionOnMount(`actionName`)

Avoid calling useEffect manually. Just pass the action name and it will be executed on component mount automatically.

import { useActionOnMount, useGetter } from 'vuex-but-for-react';

const PostsPage = () => {
  useActionOnMount('POSTS_FETCH');
  const posts = useGetter('posts');

  return (
    ...
  )
}
