How to Debug React Components using React Developer Tools

Introduction

Since React apps are made to scale and grow quickly, it’s easy for subtle bugs to infiltrate your code. The  React Developer Tools browser extension can help you track down these bugs by giving you more insight into the current  state for each  component. React Developer Tools gives you an interface for exploring the React component tree along with the current  props, state, and  context for individual components. React Developer Tools also lets you determine which components are re-rendering and can generate graphs to show how long individual components take to render. You can use this information to track down inefficient code or to optimize data-heavy components.

This tutorial begins by installing the React Developer Tools browser extension. You’ll then build a text analyzer as a test application, which will take a block of text and display information such as word count, character count, and character usage. Finally, you will use React Developer Tools to explore the text analyzer’s components and keep track of the changing props and context. The examples will use the  Chrome browser, but you can also use the plugin for  Firefox.

By the end of this tutorial, you’ll be able to start using the React Developer Tools to debug and explore any React project.

Prerequisites

  • To use the Chrome React Developer Tools extension, you will need to download and install the  Google Chrome web browser or the open-source  Chromium web browser. You can also following along using the  React Developer Tools FireFox plugin for the  FireFox web browser.
  • You will need a development environment running  Node.js; this tutorial was tested on Node.js version 10.22.0 and npm version 6.14.6. To install this on macOS or Ubuntu 18.04, follow the steps in  How to Install Node.js and Create a Local Development Environment on macOS or the Installing Using a PPA section of  How To Install Node.js on Ubuntu 18.04.
  • A React development environment set up with  Create React App. To set this up, follow Step 1 — Creating an Empty Project  of the How To Manage State on React Class Components tutorial, which will remove the non-essential boilerplate. This tutorial will use debug-tutorial as the project name.
  • You will be using React components and Hooks in this tutorial, including the useState and context Hooks. You can learn about components and Hooks in our tutorials  How To Create Custom Components in React,  How To Manage State with Hooks on React Components, and  How To Share State Across React Components with Context.
  • You will also need a basic knowledge of JavaScript and HTML, which you can find in our  How To Build a Website with HTML series and in  How To Code in JavaScript. Basic knowledge of CSS would also be useful, which you can find at the  Mozilla Developer Network.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

React 18: Things You Need To Know About React JS Latest Version

The most awaited version of React 18 is finally out now. Its team has finally revealed the alpha version of React 18 and its plan, though the official launch is still pending. This time the team has tried something and released the plan first to know their user feedback because the last version of React 17 was not that much appreciated among developers.

According to Front-end Frameworks SurveyReact JS has ranked top in the list of most loved frameworks. Thus, the developer communities expect a bit higher from the framework, so they are less appreciative of the previous launch.
ReactJS stats.pngSo, this time React 18 will be a blast. For beginners, the team is working on a new approach. They have called a panel of experts, library authors, educators, and developers to take part in a working group. Initially, it will be a small group.

I am not a part of this release but following the team on their GitHub discussion group. After gathering the information from there, I can say that they have planned much better this time.

React 17 was not able to meet the developer's community. The focus was all primarily centered on making it easier to upgrade React itself. React 18 release will be the opposite. It has a lot of features for react developers.
