We will introduce how to add an image in React.
Image Tag in React
First, we will add a div with class root in the index.html file.
# react
<div id="root"></div>
In the index.tsx file, we will define the name, url, and title of the image.
# react
import React, { Component } from 'react';
import { render } from 'react-dom';
import Hello from './Hello';
import './style.css';
interface AppProps { }
interface AppState {
name: string;
url: string;
title: string;
}
class App extends Component<AppProps, AppState> {
constructor(props) {
super(props);
this.state = {
name: 'React',
url: 'https://images.pexels.com/photos/8549835/pexels-photo-8549835.jpeg?auto=compress&cs=tinysrgb&dpr=2&h=650&w=940',
title: "Vase Image"
};
}
render() {
return ();
}
}
render(<App />, document.getElementById('root'));
We have taken an example picture. Now we will return an image by passing values in the image tag.
# react
<div>
<img src={this.state.url} alt={`${this.state.title}'s picture`} className="img-responsive" />
<span>Hello {this.state.name}</span>
</div>
So, our code in index.tsx will look like the one below.
# react
import React, { Component } from 'react';
import { render } from 'react-dom';
import Hello from './Hello';
import './style.css';
interface AppProps { }
interface AppState {
name: string;
url: string;
title: string;
}
class App extends Component<AppProps, AppState> {
constructor(props) {
super(props);
this.state = {
name: 'React',
url: 'https://images.pexels.com/photos/8549835/pexels-photo-8549835.jpeg?auto=compress&cs=tinysrgb&dpr=2&h=650&w=940',
title: "Vase Image"
};
}
render() {
return (
<div>
<img src={this.state.url} alt={`${this.state.title}'s picture`} className="img-responsive" />
<span>Hello {this.state.name}</span>
</div>
);
}
}
render(<App />, document.getElementById('root'));
Let’s add some CSS code to resize our image.
# react
.img-responsive{
width: 90vw;
}
Output:
We can now see that we have easily added images in React.
