1. Adding Images​

To include images in your React app, follow these simple steps:

Step 1: Prepare Your Image​

Before adding an image, make sure you have it in a suitable format like JPEG, PNG, or GIF. Also, consider resizing or compressing images to optimize your app's performance.

Step 2: Import the Image​

In your component file, import the image using ES6's import statement:

App.js
import React from 'react';
import logo from './path/to/your/logo.png';

function App() {
  return (
    <div>
      <img src={logo} alt="Logo" />
    </div>
  );
}

export default App;

Step 3: Display the Image​

Now, you can display the imported image using the img tag as shown above. Don't forget to add an informative alt attribute for accessibility purposes.

2. Using Fonts​

Custom fonts can greatly enhance the visual appeal of your React app. Here's how you can include them:

Step 1: Obtain the Font Files​

Find or download the font files (usually in .ttf, .woff, or .woff2 formats) you want to use and place them in a directory within your project, such as src/fonts/.

Step 2: Create a CSS File​

Create a new CSS file, e.g., fonts.css, in the src directory and define the font-face:

fonts.css
/* src/fonts/fonts.css */

@font-face {
  font-family: 'YourFontName';
  src: url('./path/to/your/font.woff2') format('woff2'),
       url('./path/to/your/font.woff') format('woff');
  /* Add more formats for compatibility if necessary */
  font-weight: normal;
  font-style: normal;
}

Step 3: Import and Apply the Font​

In your main index.js file, import the fonts.css:

index.js
import React from 'react';
import ReactDOM from 'react-dom';
import './fonts/fonts.css'; // Import the CSS file

import App from './App';

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

Now, you can apply the font to specific elements in your components:

App.js
import React from 'react';

function App() {
  return (
    <div>
      <h1 style={{ fontFamily: 'sans-serif', fontSize: '24px' }}>Welcome to My App!</h1>
      <p style={{ fontFamily: 'cursive', fontSize: '16px' }}>Enjoy your stay!</p>
    </div>
  );
}

export default App;

Welcome to My App!

Enjoy your stay!

3. Handling Files​

React allows you to work with various file types easily, such as PDFs, documents, or audio files. You can handle files by providing download links or embedding media players in your app.

To link to a file for download:

App.js
import React from 'react';

function App() {
  return (
    <div>
      <a href="../../assets/ReactJS-Guide.pdf" download>Download PDF</a>
    </div>
  );
}

export default App;

Live Preview:

http://localhost:3000

To embed media, like audio:

App.js
import React from 'react';

function App() {
  return (
    <div>
      <audio controls>
        <source src="./path/to/your/audio.mp3" type="audio/mpeg" />
        Your browser does not support the audio element.
      </audio>
    </div>
  );
}

export default App;
