ReactJS Render HTML

In this tutorial, we'll explore how to render HTML in React components. React provides a powerful mechanism to dynamically generate and display HTML content, making it easy to create dynamic and interactive user interfaces.

1. Create a New React Project

If you haven't already set up a React project, you can follow the installation and set up guide provided by the React documentation or refer to our previous tutorial on installing React.

2. Import React and React-DOM

Open your project in a code editor of your choice. In your main component file (typically App.js or index.js), import the necessary dependencies by adding the following lines at the top:

3. Define a Component

Create a new component or use an existing one where you want to render HTML content. For this example, let's assume we have a component called HTMLRenderer. Define the component as follows:

In the above code, we define the function component, which contains an HTML string stored in the html Content variable. We use the dangerouslySetInnerHTML prop to render the HTML content safely within the component.

4. Render the Component

To render the component and display the HTML content, add the following code in your main component's render method:

Here, we use the ReactDOM.render() method to render the HTMLRenderer component and mount it to the root element in the HTML file (usually a <div> with the id of "root").

5. Preview the Output

Save the changes and start your React development server. Open your web browser and navigate to the specified URL (usually http://localhost:3000) to see the rendered HTML content.

To sum up, we learned how to render HTML content in React using the dangerouslySetInnerHTML prop. We created a component, defined the HTML content, and used the dangerouslySetInnerHTML prop to safely render the HTML.

By following these steps, you can easily incorporate dynamic HTML content into your React components.

Some Best Practices

  • Remember to use caution when rendering HTML directly from user inputs to prevent cross-site scripting (XSS) attacks.
  • Always sanitize and validate user-generated HTML content before rendering it in your React components.

Experiment with different HTML structures and explore React's powerful rendering capabilities. With React, you have the flexibility to create dynamic and interactive user interfaces that bring your web applications to life.

In the next tutorial, we will learn about React Fragment which will help you simplify the structure of your React applications.


In React, you can render HTML content using JSX syntax. JSX allows you to write HTML-like code within your JavaScript files. To render HTML content, you can use React's dangerouslySetInnerHTML attribute. This attribute accepts an object with a __html property containing the HTML content you want to render. For example, <div dangerouslySetInnerHTML={{ __html: '<p>Hello, <strong>React</strong>!</p>' }}></div> will render the HTML content inside the <div> element. However, be cautious when using this approach, as it can pose security risks if the HTML content comes from an untrusted source. Ensure that you sanitize and validate the HTML content before rendering it.

Yes, you can mix React components with raw HTML in the render method. React allows you to combine JSX syntax (for creating React components) with plain HTML. You can include HTML tags directly in your JSX code and use React components alongside them. For example, you can have a parent React component that renders a mixture of HTML tags and child React components within its render() method. This allows you to create dynamic and interactive UIs by combining the power of React components with the flexibility of HTML.

In React, you can conditionally render HTML content by utilizing JavaScript expressions within JSX. You can use conditional statements, such as if or ternary operators, to determine whether to render specific HTML content. For example, you can use the if statement inside the render() method to conditionally render different HTML elements based on certain conditions. Additionally, you can assign the result of the condition to a variable or use inline ternary operators directly in JSX to conditionally render specific HTML content. This approach allows you to control the rendering of HTML based on dynamic data or application state.
