Introduction to React Chrome Extensions

Google developed Google Chrome (or just Chrome), a popular internet browser. One of the reasons Chrome browser is the most popular browser for web development is that it has Chrome developer tools out of the box and allows third-party dev tools to be installed to the browser, to provide more capabilities for web development aka React Chrome extension.

Developers call Chrome third-party dev tools extensions, which allow developers to detect what’s wrong with their app in a development environment. You can install all Chrome DevTools from the Chrome extension marketplace.

Similarly, Figma allows users to download and use Figma plugins on the tool itself. CopyCat is a Figma to React tool that converts Figma design to React code with the click of a button. Eliminate messy handoffs with production ready code and speed up development by focusing your time solving challenges you want.

Creating A New React APP

React is a JavaScript UI library for developing visual components for single-page applications.

To follow along properly and test out how some of these extensions work. Create a new React project with the command below:

npx create-react-app my-react-project

The command above will create a new project named my-react-project using Create React APP CLI. If you don’t know what a Create React App CLI is, you should check this guide.

We’ll use the newly created project to experiment with all the React Chrome developer tools we’ll explore in this article.

Start your React app with the command below:

npm run start

A new tab will be opened on your browser and our React app page should look something like this:

What is a React Chrome Extension

A React Chrome extension is a developer tool (or DevTools) that is dedicated to developing and maintaining a React app. They’re useful for debugging and inspecting React components, States, Redux, Context API, React DOM elements, etc.

Listed below are the top 13 React Chrome extensions that boost your productivity as a React developer. Maybe you’ll find your favorite chrome extension here.

1. React Developer Tools

The first extension on the list is the React developer tools. It’s the official Chrome DevTools extension for the open-source React JavaScript library, allowing you to inspect and visually analyze the React component hierarchies in the Chrome Developer Tools.

Facebook React Team maintains the React developer tool extension.

How to Install React Developer Tools Extension?

Below is a quick guide on how to install the React developer tools. This step will be used in installing any other React dev tool from the Chrome Webstore.

  • Visit the Chrome extension marketplace
  • Search for React developer tools and click the “Add to Chrome” button to install the React DevTools extension:
  • Click on the “Add extension” button from the popup:
  • You’ll get this popup notification after a successful installation:

This tutorial uses the Chrome extension 4.24.7 version and yours might be a little different depending on the version you have.

After installing the React developer tools, two new tabs will be added to your Chrome DevTools, as illustrated below: the tabs” ⚛️ Profiler” and “⚛️ Components.”

You’ve learned how to install a Chrome extension in this section. We’ll go over how to make use of the React DevTools tab ‘components’ in the next section.

How To Use The React Developer Tools Components Tab

The Components tab displays the React root components that were rendered on the page, as well as the child components that are rendered within the root components.

Let’s say you have a Button.jsx component that accepts a text prop, with the following:

import React from "react";

export const Button = ({ text }) => {
  return <button>{text}</button>;

Then import it inside of your <App /> component. You should have something like this on your page:

You can inspect your React page component tree by navigating to your Chrome React DevTools Components tab, as illustrated below:

From the illustration above, the tab shows that we only have two React components rendered in our React dom: the App component and the Button component that we created.

By selecting one of the components in the tree, we can easily inspect and edit any of their current props and state in the panel on the right, as demonstrated below:

You can also inspect the selected component (i.e the Button component) to know which component rendered it (i.e the App component rendered the Button component), the component that created the App component, and the version of the react-dom you’re using.


How To Use The React Developer Tools Profiler Tab

The Profiler tab is the second feature you’ll find in the React devtool. It allows you to record the performance and detect issues in your React app.

According to the React documentation – “The profiler tab plugin uses React’s experimental Profiler API to collect timing information about each component that is rendered to identify performance bottlenecks in a React application”.

To see how Profiler Tab works, update your Button component with the following code:

import React from "react";

export const Button = ({ text, handleClick }) => {
  return <button onClick={() => handleClick()}>{text}</button>;

The Button component above accepts two props, the text which is the button text, and the handleClick which is a function that’ll be executed when the button is clicked.

Next, update your App.js file with the following:

import React from "react";
import "./App.css";
import { Button } from "./components/Button";

function App() {
  const [count, setCount] = React.useState(0);

  const handleClick = () => {
    setCount(count + 1);

  return (
    <div className='App App-header'>
      <p> {count} </p>
      <Button text={"Click me"} handleClick={handleClick} />

export default App;

From the code above, the handleClick function increases the count state by 1 each time the button is clicked:

On the Profiler tab, click on the start recording icon:

Once the Profiler has started recording, React DevTools will automatically collect the performance information of each component each time your application renders.

To make our component rerender, click the button up to 5 times (or make your component be re-rendered once or more). Click the stop recording icon “🔴” when you’re done.

Generate a Visual Report

The Profiler tab will generate a visual report indicating the number of times your components are re-rendered and the duration it takes for each render (i.e we clicked the button 5 times, and the Profile tab detects the render time for each of the clicks).

The first click took 3.1ms to render:

While the 5th click took 0.7ms to render:

This makes more sense in a robust React application when the time complexity is crucial.

You can learn more about the React Developer Tools “⚛️ Profiler tab” from the official React documentation here.

You can also learn more about React Developer Tools. How to use the “⚛️ Profiler tab” and the “⚛️ Components tab” from the video below:

2. Redux DevTools

As a React developer using React Redux for state management, this is a must-have extension for you to have installed as one of your React Chrome developer tools or as a standalone app. Redux DevTools enables you to monitor triggered actions and their effect on your Redux state.

You can install the Redux DevTools extension from the Chrome Webstore here.

And install it into your project with the single command line below:

npm install --save redux-devtools-extension

Redux DevTools extension allows you to do the following in your React app:

  • Persist Redux store on page reload
  • Inspect every state and action payload in your Redux store.
  • Keep track of all changes in your Redux state

3. React Context DevTool

Similar to React Redux, context API is used for managing states in a React app, you can learn the difference here.

Users use React Context DevTool to debug and keep track of state changes in React Context and useReducer API.

You can install the React Context DevTool extension from the Chrome Webstore here (This extension requires you to have the React Developer Tools installed on your browser).

React Context DevTool allows you to do the following in your project:

  • Inspect every state and action payload in your Context API store.
  • Keep track of all state changes in your Context API
  • Keep track of actions and their effects on states in Context API

4. React Performance Devtool

The React Performance Devtool focuses on diagnosing why React components are not performing how they’re expected to and why they take a longer time to load.

React Performance Devtool helps you:

  • Remove or unmount unused components in your React apps.
  • Inspect what is blocking or taking more time after an operation has been started.
  • Examine which components are taking more time to load.

Below is the official demo of how to use React Performance Devtool:

5. React VT

React VT is a visual component testing tool for React apps. It presents a live view of your React component structure, along with its current state and props.
