Feature Comparison: react-tracked vs recoil vs zustand

API Design

  • react-tracked:

    react-tracked offers a simple and intuitive API that allows you to create tracked state with minimal boilerplate. It focuses on performance by using a subscription model to ensure that only components that depend on specific state updates will re-render, making it efficient for large applications.

  • recoil:

    Recoil provides a more complex API that includes atoms and selectors, allowing for fine-grained state management. Atoms represent pieces of state, while selectors can compute derived state or perform asynchronous queries. This design enables powerful state management capabilities tailored to complex applications.

  • zustand:

    Zustand features a very minimalistic API that is easy to understand and use. It allows you to create a store with a simple function and provides hooks to access and update state. This simplicity makes it a great choice for developers looking for a straightforward solution.

React Tracked

CI npm size discord

State usage tracking with Proxies. Optimize re-renders for useState/useReducer, React Redux, Zustand and others.

Documentation site: https://react-tracked.js.org

Introduction

Preventing re-renders is one of performance issues in React. Smaller apps wouldn't usually suffer from such a performance issue, but once apps have a central global state that would be used in many components. The performance issue would become a problem. For example, Redux is usually used for a single global state, and React-Redux provides a selector interface to solve the performance issue. Selectors are useful to structure state accessor, however, using selectors only for performance wouldn't be the best fit. Selectors for performance require understanding object reference equality which is non-trival for beginners and experts would still have difficulties for complex structures.

React Tracked is a library to provide so-called "state usage tracking." It's a technique to track property access of a state object, and only triggers re-renders if the accessed property is changed. Technically, it uses Proxies underneath, and it works not only for the root level of the object but also for deep nested objects.

Prior to v1.6.0, React Tracked is a library to replace React Context use cases for global state. React hook useContext triggers re-renders whenever a small part of state object is changed, and it would cause performance issues pretty easily. React Tracked provides an API that is very similar to useContext-style global state.

Since v1.6.0, it provides another building-block API which is capable to create a "state usage tracking" hooks from any selector interface hooks. It can be used with React-Redux useSelector, and any other libraries that provide useSelector-like hooks.

Install

This package requires some peer dependencies, which you need to install by yourself.

npm add react-tracked react scheduler

Usage

There are two main APIs createContainer and createTrackedSelector. Both take a hook as an input and return a hook (or a container including a hook).

There could be various use cases. Here are some typical ones.

createContainer / useState

Define a useValue custom hook

import { useState } from 'react';

const useValue = () =>
  useState({
    count: 0,
    text: 'hello',
  });

This can be useReducer or any hook that returns a tuple [state, dispatch].

Create a container

import { createContainer } from 'react-tracked';

const { Provider, useTracked } = createContainer(useValue);

useTracked in a component

const Counter = () => {
  const [state, setState] = useTracked();
  const increment = () => {
    setState((prev) => ({
      ...prev,
      count: prev.count + 1,
    }));
  };
  return (
    <div>
      <span>Count: {state.count}</span>
      <button type="button" onClick={increment}>
        +1
      </button>
    </div>
  );
};

The useTracked hook returns a tuple that useValue returns, except that the first is the state wrapped by proxies and the second part is a wrapped function for a reason.

Thanks to proxies, the property access in render is tracked and this component will re-render only if state.count is changed.

Wrap your App with Provider

const App = () => (
  <Provider>
    <Counter />
    <TextBox />
  </Provider>
);

createTrackedSelector / react-redux

Create useTrackedSelector from useSelector

import { useSelector, useDispatch } from 'react-redux';
import { createTrackedSelector } from 'react-tracked';

const useTrackedSelector = createTrackedSelector(useSelector);

useTrackedSelector in a component

const Counter = () => {
  const state = useTrackedSelector();
  const dispatch = useDispatch();
  return (
    <div>
      <span>Count: {state.count}</span>
      <button type="button" onClick={() => dispatch({ type: 'increment' })}>
        +1
      </button>
    </div>
  );
};

createTrackedSelector / zustand

Create useStore

import create from 'zustand';

const useStore = create(() => ({ count: 0 }));

Create useTrackedStore from useStore

import { createTrackedSelector } from 'react-tracked';

const useTrackedStore = createTrackedSelector(useStore);

useTrackedStore in a component

const Counter = () => {
  const state = useTrackedStore();
  const increment = () => {
    useStore.setState((prev) => ({ count: prev.count + 1 }));
  };
  return (
    <div>
      <span>Count: {state.count}</span>
      <button type="button" onClick={increment}>
        +1
      </button>
    </div>
  );
};

Notes with React 18

This library internally uses use-context-selector, a userland solution for useContextSelector hook. React 18 changes useReducer behavior which use-context-selector depends on. This may cause an unexpected behavior for developers. If you see more console.log logs than expected, you may want to try putting console.log in useEffect. If that shows logs as expected, it's an expected behavior. For more information:
