Comprehensive React JS Course with 6+ projects and 15 hours of content – 2024

React JS has become one of the most popular front-end JavaScript libraries for building interactive user interfaces. With React, you can create dynamic and responsive web applications that are easy to maintain and scale. In this tutorial, we will cover the full course of React JS along with 6+ projects and approximately 15 hours of content.

Before we begin, ensure that you have Node.js and npm installed on your system as React applications require them to run.

1. Introduction to React JS

React JS is a declarative, efficient, and flexible JavaScript library for building user interfaces. It was developed by Facebook and is maintained by a community of developers. React works by creating components that represent various parts of the user interface. These components can be reused throughout the application, making it easy to build complex user interfaces.

1. Setting up a React Project

To create a new React project, you can use the create-react-app tool. Run the following command in your terminal to install create-react-app globally:

npm install -g create-react-app

Then, create a new React project by running the following command:

create-react-app my-react-app
cd my-react-app
npm start

This will start a development server and open the React application in your default web browser. You can start modifying the code in the src folder to build your React application.

1. React Components

React is all about components. Components are the building blocks of a React application and are reusable pieces of code that represent a part of the user interface. You can create components by extending the React.Component class or by using stateless functional components. Here is an example of a simple component:

import React from 'react';

class App extends React.Component {
  render() {
    return (
      <div>
        <h1>Hello, World!</h1>
      </div>
    );
  }
}

1. State and Props

State and props are two important concepts in React. State is mutable data that belongs to a component and can be updated using the setState method. Props are immutable data that are passed from a parent component to a child component. Here is an example of a component using state and props:

import React from 'react';

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      message: 'Hello, World!'
    };
  }

  render() {
    return (
      <div>
        <h1>{this.state.message}</h1>
        <ChildComponent message={this.state.message} />
      </div>
    );
  }
}

const ChildComponent = (props) => {
  return <p>{props.message}</p>;
}

1. React Routing

React Router is a library that allows you to add routing to your React application. You can define different routes in your application and render different components based on the current route. Install react-router-dom by running the following command:

npm install react-router-dom

Then, define routes in your application by importing Route and BrowserRouter from react-router-dom:

import React from 'react';
import { BrowserRouter, Route, Switch } from 'react-router-dom';

const App = () => {
  return (
    <BrowserRouter>
      <Switch>
        <Route exact path="/" component={Home} />
        <Route path="/about" component={About} />
      </Switch>
    </BrowserRouter>
  );
}

const Home = () => <h1>Home Page</h1>;
const About = () => <h1>About Page</h1>;

1. Hooks and Context API

Hooks are a new feature introduced in React 16.8 that allow you to use state and other React features without writing a class. The useContext hook allows you to pass data through the component tree without having to pass props down manually at every level. Here is an example of using the useContext hook:

import React, { useContext } from 'react';

const MyContext = React.createContext();

const App = () => {
  return (
    <MyContext.Provider value="Hello, World!">
      <ChildComponent />
    </MyContext.Provider>
  );
}

const ChildComponent = () => {
  const value = useContext(MyContext);
  return <p>{value}</p>;
}

1. 6+ Projects

Throughout this course, you will build 6+ projects to practice your React skills. These projects will cover a range of topics including:

• A Todo List app to practice basic React concepts
• A Weather App using a third-party API
• A GitHub Profile Finder app to search for GitHub profiles
• A Movie App to display information about movies
• An E-commerce Website to practice complex component structures
• A Blogging Platform to practice routing and state management
