Convert String to HTML in React: Rendering Text as HTML Content

by

This article will use a practical example to explore how to convert string to HTML in React. We will cover two approaches: Using the dangerouslySetInnerHTML prop and a third-party library called react-html-parser.

To convert HTML to React, you can use the dangerouslySetInnerHTML prop. These approaches allow you to parse and render HTML content within React components: practice alert and clean contributions to forestall security weaknesses.

Respond is a JavaScript library that permits designers to construct intelligent and reusable UIs. While working with Respond, there might be times when you want to change over a line of HTML content into genuine HTML components. This can be helpful while delivering an active substance. Or when you get HTML content from an outside source, like a Programming interface. You can also learn five different ways to use a JavaScript Variable in HTML.

Convert String to HTML in React

Here are some approaches to try out:

Approach 1 to convert string to HTML in react: Using dangerouslySetInnerHTML

When using Respond, be cautious with the dangerouslySetInnerHTML prop for embedding HTML content into a component. Misuse can lead to cross-site scripting attacks.

convert string to html in react

We should consider a basic model with a Respond part called HTMLRenderer. This part takes a line of HTML content as a prop and delivers it as HTML components:

HTML to JSX

import React from ‘react’;

const HTMLRenderer = ({ HTML content }) => { return ( <div dangerouslySetInnerHTML={{ __html: HTML content }}></div> ); } export default HTMLRenderer;

In the above example, we use the dangerouslySetInnerHTML prop on an <div> element and pass the htmlContent as the value. React will then parse and render the HTML content within the <div> element.

To use this part and convert a string to HTML, you can pass the HTML string as a prop:



</strong>

<strong>import Respond from 'respond'; import HTMLRenderer from './HTMLRenderer'; const Application = () => { const htmlString = '<h1>Hello, world!</h1>'; return ( <div> <HTMLRenderer htmlContent={htmlString}/> </div> ); } send out default Application;</strong>

<strong>




In this model, the <h1> label inside the HTML String will be delivered as a genuine heading component on the page for react render HTML string.


Approach 2 to convert string to HTML in react: Utilizing respond html-parser


If you like to use an outsider library for text-to-HTML converter online, responding to html-parser gives a helpful method. It helps in rendering HTML content in Respond parts.

use respond HTML parser


To use respond html-parser, begin by introducing it in your undertaking:


CSS


npm introduces respond html-parser


Once introduced, you can import and involve it in your part:


jsx


import Respond from ‘respond’; import ReactHtmlParser from ‘respond html-parser’; const HTMLRenderer = ({ HTML content }) => { return ( <div>{ReactHtmlParser(HTML content)}</div> ); } send out default HTMLRenderer;


In this method, we use ReactHtmlParser. Convert HTML to React components with ease using this tool. Simply pass in the HTML string as a parameter and receive parsed components, ready to be enclosed within curly braces and a <div> component.


To use the part, follow a comparative example as in the past:


jsx


import Respond from ‘respond’; import HTMLRenderer from ‘./HTMLRenderer’; const Application = () => { const htmlString = ‘<h1>Hello, world!</h1>’; return ( <div> <HTMLRenderer htmlContent={htmlString}/> </div> ); } trade default Application;


This model’s outcome will equal the past method, with the <h1> label delivered as a heading component.


These were two approaches to try if you want to convert string to HTML in React.


Advantages and Disadvantages of Converting String to HTML in React


This cycle considers the dynamic delivery of HTML and works with a mix of outside HTML content. Converting HTML content into actual elements has its pros and cons when using Respond. We will investigate the two sides of switching strings completely to HTML in Respond.


advantages and disadvantages


Advantages


Here are some advantages:


Dynamic Content Rendering


Converting a string to HTML enables the dynamic rendering of HTML content based on variables or data from APIs. This flexibility allows React components to adapt and display content.


Integration with External Content


When interacting with external sources, such as APIs or databases, it is standard to receive HTML content as strings. React can seamlessly integrate and display the content within its components, converting these strings to HTML elements. This ultimately provides a consistent user experience.


Rich Text Editing


Converting strings to HTML allows for easy display and rendering of formatted text, including headings, paragraphs, lists, and embedded media in React.


Reusability


By converting strings to HTML, you can create reusable components that handle the parsing and rendering of HTML content. This promotes code modularity and reduces duplication, making managing and maintaining your React application easier.


Disadvantages


Here are some disadvantages:


Security Concerns


Converting strings to HTML introduces potential security risks. Unsanitized HTML content from untrusted sources can lead to XSS attacks. To mitigate these risks, you should sanitize and confirm the HTML content.


Performance Implications


Parsing and rendering HTML content can have performance implications when dealing with large or complex HTML strings. Converting strings to HTML elements requires more computational resources, which can impact your React application’s performance.


Limited Control over Styling


When converting strings to HTML, styling the rendered elements can become challenging. HTML content often includes inline styles or classes. Integrating them into React’s styling system can take time and effort. Maintaining consistent styling across the application may need extra effort.


Code Complexity


Converting strings to HTML and managing HTML content in React components can result in code complexity and require extra logic.
