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.

What are hooks in React JS? - INFO AT ONE

In this article, you will learn what are hooks in React JS? and when to use react hooks? React JS is developed by Facebook in the year 2013. There are many students and the new developers who have confusion between react and hooks in react. Well, it is not different, react is a programming language and hooks is a function which is used in react programming language.

Build Your Own Meme Generator with React, React Hooks and TypeScript

The best way to learn something is by doing. It works even better if it means working on something for fun. So, how about learning about React, React hooks and TypeScript by building your own meme generator? This tutorial will show you how to do it.

You can find the code on my GitHub.

Briefing

This meme generator will allow you to generate png or jpg image from HTML content. This content can be anything you want. For this project, it will be a single image and two headings, positioned absolutely on the image. The first heading will be at the top of the image and the second will be at the bottom.

You will be able to add the image in two ways. First, the meme generator will fetch random image from api.imgflip.com. Don’t worry, no token or registration required. Second, you will be able to open image from your disk, using file input. To generate the png or jpg file this meme generator will use dom-to-image-more package.

About the code. This tutorial will use React hooks such as useStateuseEffect and useRefs. Since you will use hooks there is no need for class components. So, you will build all components for your meme generator as functional components. You will write this meme generator in TypeScript and you will also work with interfaces and types.

Project setup

Let’s set up the files you will need to build your meme generator. You can do this very quickly by using create-react-app as your starting template. If you want, you can install this package globally on your computer, with your favorite package manager (pnpmyarn or npm). However, this is not really necessary.

You can also create the starting template without installing anything. This can be done either with npx, instead of npm, or pnpx, instead of pnpm. These two commands will download the desired package, install it temporarily, automatically start it, and remove it after you are done. No need to fill your HDD.

One more thing, you will write this meme generator in TypeScript, a superset of JavaScript. If you want to create the starter template with create-react-app with support for TypeScript you have to include --typescript flag in the command. If you don’t want to use TypeScript in this project, omit the --typescript flag.

To the installation. For npx, use npx create-react-app react-meme-generator-ts --typescript. You can also use npm directly, npm init react-meme-generator-ts --typescript. For pnpx, it will be npx create-react-app react-meme-generator-ts --typescript. For yarn, use yarn create react-app react-meme-generator-ts --typescript.

These commands will create a starter template for your meme generator. Now, let’s also add the dom-to-image-more package. When you are done with this, you are ready to start. Your package.json will look something like this:

{
  "name": "react-meme-generator-ts",
  "version": "1.0.0",
  "description": "Meme generator web app built with React, React hooks and TypeScript.",
  "license": "MIT",
  "private": false,
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ],
  "main": "src/index.tsx",
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  },
  "dependencies": {
    "dom-to-image-more": "2.8.0",
    "react": "16.11.0",
    "react-dom": "16.11.0",
    "react-scripts": "3.2.0"
  },
  "devDependencies": {
    "@types/react": "16.9.11",
    "@types/react-dom": "16.9.3",
    "typescript": "3.6.4"
  }
}

One thing. Below is the final structure of the meme generator you are going to build. You can use this to help yourself orient in the code.

Validating React Forms With React-Hook-Form

Validating inputs is very often required. For example, when you want to make sure two passwords inputs are the same, an email input should in fact be an email or that the input is not too long. This is can be easily done using React Hook From. In this article, I will show you how.

Required Fields

The most simple, yet very common, validation is to make sure that an input component contains input from the user. React Hook Form basic concept is to register input tags to the form by passing register() to the tag’s ref attribute. As we can see here:
