What is the Hook System in React?
The React hooks system allows you to write reusable code for any kind of React components. This reusability is important for large-scale projects where lots of teams need to reuse existing components to build new features. The hooks system works by creating small methods that the React compiler can recognize and replace with its own implementation. This system allows you to write small methods that can be replaced with larger ones where needed. The React Hooks system can be used with classes, functions, or even components.
Create new React app with Hooks
In React, you create new apps with create-react-app. This tool scaffolds out a new app with all the required React components and boilerplate code. If you want to create a new app that is different from the default one, you can use create-react-app. The default app that comes with create-react-app can be modified by adding components or changing the app’s functionality. For example, you can change the app’s functionality to display a different kind of information. If you want to create a new app from scratch, you can use create-react-app. To make things more interesting, let’s create an app that shows the names of all the states in the United States of America.
Install and Setup UsState Hook in our App
To get started, we’ll start by installing the hook system and importing its components in our app We’ll also need to install the react-hooks package in our app so that we can use the hook system. To do this, we’ll run the following command in our app’s terminal Next, we’ll import the usState hook in our app by adding the following line of code at the end of our app’s code
Write our First UsState Hook Component
Let’s write a component to display the names of all the states of the United States of America. This is the place where we’ll write the hook code to import the react-state hook and use it to get all the states. We’ll start by creating a new file in our app with the name “Index.js”. To create this file, we’ll run the command in our app’s terminal like below. We’ll append the file name after the file name, e.g. “index.js”. Next, we’ll import the hook system. To do this, we’ll add the following code at the end of “index.js”
In this tutorial, we learned how to use the hook system in React and create a component for displaying the names of all states in the United States of America. We also added the hook system to our app with the usState hook. We can create new React apps with create-react-app, and we can modify them to fit our needs. We can also use hook systems like the react-hooks system to make components re-usable.
