React get html from component

Rendering the HTML string in React

In this tutorial, we are going to learn about how to render the html string as real dom elements in React app.

If we try to use JSX curly brace syntax < >to render an html string, react will treated it as a plain text (to prevent from the cross-site scripting attacks).

import React from "react"; export default function App()   const htmlString = "

Hello World

"
;
return div>htmlString>/div>; >

To render the html string in react, we can use the dangerouslySetInnerHTML attribute which is a react version of dom innerHTML property.

import React from "react"; export default function App()   const htmlString = "

Hello World

"
;
return div dangerouslySetInnerHTML= __html: htmlString >>> /div>; >

The term dangerously is used here to notify you that it will be vulnerable to cross-site scripting attacks (XSS).

Similarly, you can also use the html-react-parser library to render the html string.

import React from "react"; import parse from "html-react-parser"; export default function App()  const htmlString = "

Hello World

"
; return div>parse(htmlString)>/div>;>

How to render a React element to an HTML string?

What happens when you want to render a React string or element to an HTML string? For some reasons, you may want to have the generated HTML string from your React component instead of a mounted component and render it on the page.

If you want to render an HTML String for SSR purposes, you may consider using a framework like Next.js instead of manually rendering a React string to HTML. Using a framework like Next.js can offer a wide range of features and tools for building server-rendered applications like abstracting away a lot of the complexity of setting up server rendering, automatic code splitting, significant performance improvements, . etc.

What is ReactDOMServer?

The ReactDOMServer module is a part of the official React library. It provides methods for rendering React components to static HTML. It’s useful for server-side rendering, where you want to generate HTML on the server and send it to the client.

Converting a React String to an HTML String

To convert a React string to an HTML string, we need to use the renderToString method provided by ReactDOMServer. The renderToString method takes a React component as an argument and returns a string of HTML.

Here is an example of how to use the renderToString method to convert a React string to an HTML string:

import React from 'react'; import ReactDOMServer from 'react-dom/server';  const reactString = '
Hello, world!
'
;
const htmlString = ReactDOMServer.renderToString(React.createElement('div', dangerouslySetInnerHTML: __html: reactString > >)); console.log(htmlString); // Output:
Hello, world!

In this example, we are using React.createElement to create a React element with the dangerouslySetInnerHTML prop set to < __html: reactString >. The dangerouslySetInnerHTML prop is used to render HTML directly to the page. Then, the ReactDOMServer.renderToString function convert the React element to an HTML string.

Here is another example but with a custom component you already created before. This example convert a JSX to string.

import  renderToString > from 'react-dom/server'  renderToString(YourAwesomeComponent props1="value1" props2= value: '2' >> />) 

The renderToString function can be used on both server-side and client-side. If you want to render all page server-side for SEO or UX purposes for example, you can use the ReactDOMServer.renderToNodeStream function to improve your load time or the ReactDOMServer.renderToPipeableStream in newer React versions. You can find an example for this last method on the renderToPipeableStream Documentation.

[Solved]-How to get html code from reactjs component-Reactjs

To get HTML from a react component, you can use the ReactDOMServer.renderToString method (doc) used mainly for SSR purpose. However I guess you can achieve what you want with it.

Gaël S 1528

There are two ways to do that. One is the renderToString() method, as the other answer mentions.

Similar to renderToString, except this doesn’t create extra DOM attributes that React uses internally, such as data-reactroot. This is useful if you want to use React as a simple static page generator, as stripping away the extra attributes can save some bytes.

If you plan to use React on the client to make the markup interactive, do not use this method. Instead, use renderToString on the server and ReactDOM.hydrate() on the client.

For sending email you don’t need extra DOM attributes or hydration since the email doesn’t include any JS code, renderToStaticMarkup() will do the job.

You can use renderToString of react-dom/server and use it like

import ReactDOMServer from 'react-dom/server' const htmlString = ReactDOMServer.renderToString() 

ReactDOMServer is used for SSR (Server Side Rendering) of react components.

renderToString converts your React component to string. So, You will get string html from JSX of your component.

2 Ways to Render HTML Content in React and JSX

There might be times when you need to render HTML content in a single-page app made with React. For instance, you have a blog or a news website that uses React for the front end and use a headless CMS for the back end. In this case, one of the most important tasks is to fetch data from the backend via REST API or GraphQL and then display it to your users.

This article walks you through 2 examples that use different techniques to render raw HTML in React.

Using dangerouslySetInnerHTML

In vanilla javascript, you have the innerHTML property to set or return the HTML content (inner HTML) of an element. In React, you can use dangerouslySetInnerHTML to let React know that the HTML inside of that component is not something it cares about.

Example

// App.js // Kindacode.com const rawHTML = ` 

The rat hates the cat

This is something special

H2

H3

Just Another Heading

`; const App = () => < return (
>
>>
); >; export default App; // Styling const container =

You can find more information about dangerouslySetInnerHTML in the React official docs.

Using a third-party library

If you have a strong reason not to use dangerouslySetInnerHTML, you can use a third-party library that doesn’t use dangerouslySetInnerHTML internally. There are several npm packages that meet this requirement, such as html-to-react or react-render-html.

The example below uses html-to-react. You can install it by running:

npm install html-to-react --save

Example

// App.js // Kindacode.com import < Parser >from 'html-to-react' const rawHTML = ` 

The Second Example

This is something special



Just Another Heading

`; const App = () => < return (
> ); >; export default App; // Styling const container = < width: 500, margin: 'auto' >;

Conclusion

You’ve learned a couple of different approaches to rendering raw HTML in JSX and React. If you’d like to explore more new and interesting things about modern frontend development, take a look at the following articles:
