Introduction

When migrating from Redux to Jotai, developers often encounter challenges in replicating the functionality of their existing Redux setup. One such issue is the lack of an action to clear history in Jotai. In this article, we will explore how to implement a clear history or jump action in Jotai, similar to the functionality provided by Redux-undo.

Understanding Jotai and Redux-undo

Jotai is a state management library for React that provides a simple and efficient way to manage global state. It uses atoms, which are immutable values that can be used to store and retrieve data. Jotai-history is a library that extends Jotai by providing a way to manage the history of state changes.

Redux-undo, on the other hand, is a library that provides a way to undo and redo state changes in a Redux application. It allows developers to implement a clear history or jump action, which is essential for applications that require a high degree of undo and redo functionality.

Implementing a Clear History or Jump Action in Jotai

To implement a clear history or jump action in Jotai, we need to create a custom action that can be used to reset or jump to a specific state. Here's an example of how we can achieve this:

Step 1: Create a Custom Action

First, we need to create a custom action that can be used to reset or jump to a specific state. We can create a new file called clearHistory.js and add the following code:

import { atom } from 'jotai';

const clearHistory = atom(null);

export default clearHistory;

This code creates a new atom called clearHistory that can be used to store the action.

Step 2: Create a Custom Reducer

Next, we need to create a custom reducer that can handle the clear history or jump action. We can create a new file called historyReducer.js and add the following code:

import { atom, useAtom } from 'jotai';
import clearHistory from './clearHistory';

const history = atom([]);

const historyReducer = (state = [], action) => {
  switch (action.type) {
    case 'CLEAR_HISTORY':
      return [];
    case 'JUMP_TO_STATE':
      return action.state;
    default:
      return state;
  }
};

export default historyReducer;

This code creates a new reducer called historyReducer that can handle the clear history or jump action.

Step 3: Create a Custom Store

Next, we need to create a custom store that can use the custom reducer and action. We can create a new file called store.js and add the following code:

import { atom, useAtom, atomFamily, useAtomFamily } from 'jotai';
import clearHistory from './clearHistory';
import historyReducer from './historyReducer';

const store = atomFamily((key) => atomFamily(historyReducer, key));

export default store;

This code creates a new store called store that can use the custom reducer and action.

Step 4: Use the Custom Action and Reducer

Finally, we can use the custom action and reducer in our application. We can create a new file called App.js and add the following code:

import React from 'react';
import { useAtom, useAtomFamily } from 'jotai';
import clearHistory from './clearHistory';
import store from './store';

const App = () => {
  const [history, setHistory] = useAtom(store('history'));
  const [clearHistoryAction, setClearHistoryAction] = useAtom(clearHistory);

  const handleClearHistory = () => {
    setClearHistoryAction({ type: 'CLEAR_HISTORY' });
  };

  const handleJumpToState = (state) => {
    setClearHistoryAction({ type: 'JUMP_TO_STATE', state });
  };

  return (
    <div>
      <button onClick={handleClearHistory}>Clear History</button>
      <button onClick={() => handleJumpToState([1, 2, 3])}>Jump to State</button>
      <ul>
        {history.map((item, index) => (
          <li key={index}>{item}</li>
        ))}
      </ul>
    </div>
  );
};

export default App;

This code uses the custom action and reducer to clear the history and jump to a specific state.

Conclusion

In this article, we explored how to implement a clear history or jump action in Jotai, similar to the functionality provided by Redux-undo. We created a custom action and reducer, and used them in our application to clear the history and jump to a specific state. This implementation provides a high degree of undo and redo functionality, making it essential for applications that require a high degree of undo and redo functionality.
