Introduction to React Hooks - How to Get Started

Have you heard about this new feature called React hooks? A lot of people in React community are talking about them. Some people even call this feature a game changer. This brings a few questions. What are React Hooks? Why are they so hot? And, finally, how can we use them? This article will give you answers to all these questions!

What are React hooks?

You probably know that when you work with React class components you can use features such as state. In the end, that is why these components are also called stateful. You also probably know that every class component have lifecycle methods you can use. For example, componentWillUnmount()componentDidMount()componentWillUnmount(), etc.

None of this applies to functional or stateless components. Stateless components can’t use their own state and don’t have lifecycle methods. This is also why we can’t use functional components in every situation. Sometimes, we just have to use class component, or PureComponent, because functional component is not equipped to do the job.

This is no longer the truth with the introduction of React hooks. Put simply, React hooks allows us to take a React functional component and add state and lifecycle methods to it. Well, we are actually not adding a state to it. More precise will be saying that we are “hooking” the component into state and lifecycle methods.

Functional components on steroids and more freedom

Yes, that’s correct. Hooks allows functional components to use lifecycle methods, the features that were available only for class-based components. This means that we are no longer limited by the functionality of components. So, if you prefer to use functional components, the need to work with a state or lifecycle methods will prevent you from doing so.

Let’s say that we decide to use a functional component. A few days later we find out that it has to handle state or use some lifecycle methods. This is not a problem. We don’t have to rewrite our component into a class. All we need is to use a React hook. React hooks will give us access to both no matter if the component we are currently working with.

Yes, we can work with stateful or stateless components and use state and lifecycle methods as we wish. When you think about it, React hooks will help us transform what was previously a stateless component into stateful. All we need is to choose, import and use specific hook.

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.

Getting Started With React Hooks — Part 1

In this post I will try to explain how to use react hooks step by step from basics using a simple todo app.

This series assumes you already know to work with react, “create react app” and basic class components. i.e you have a basic understanding of how react works.

Lets Start

Create a new project using CRA

npx create-react-app todo-list-hooks
cd todo-list-hooks

Next i will be using bootstrap for some simple basic designs so lets install bootstrap package and include it

npm install bootstrap@next

Next open your src/index.js to add bootstrap

import '../node_modules/bootstrap/dist/css/bootstrap.min.css';

Next, we let’s clean up the default react stuff that comes so we have a clean working code.


import React from 'react';
function App() {
  return (
    <div className="App">
      {/* // will add futher code here.. */}
export default App;

Now you should have a simple blank screen to work with on your browser.

Run your react app and see browser

npm start

Basic UI Setup

Lets add a nav bar and an add todo button and few list elements. I will be using all html from bootstrap

Add this code into App.js


import React from 'react';
function App() {
  return (
    <div className="App">
      <nav className="navbar navbar-light bg-light">
        <div className="container-fluid">
          <a className="navbar-brand" href="#">Navbar</a>
          <ul class="nav">
            <li class="nav-item">
            <button type="button" className="btn btn-primary">Add Todo</button>
      <div className="container-fluid">
        <div className="row">
          <ul className="list-group">
            <li className="list-group-item d-flex justify-content-between align-items-center">
              Cras justo odio
              <span class="badge bg-danger rounded-pill">
            <li className="list-group-item d-flex justify-content-between align-items-center">Dapibus ac facilisis in</li>
            <li className="list-group-item d-flex justify-content-between align-items-center">Morbi leo risus</li>
            <li className="list-group-item d-flex justify-content-between align-items-center">Porta ac consectetur ac</li>
            <li className="list-group-item d-flex justify-content-between align-items-center">Vestibulum at eros</li>
export default App;

You should have a screen like this for now

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:
