react-html-renderer
React component that renders an HTML string as a React component tree.
Note: This component uses html-react-parser under the
hood but makes no promises about changing the underlying library in a future
release.
Status
Install
npm install --save react-html-rendererExample
import React from 'react'
import HTMLRenderer from 'react-html-renderer'
// Components to which elements are mapped
import Heading from './Heading'
import Subheading from './Subheading'
import Link from './Link'
// HTML to render as React components
const html = `
<h1>React</h1>
<h2>A JavaScript library for building user interfaces</h2>
<p>
<a href="#">Get Started</a>
</p>
`
// Note that default props can be set using the following pattern:
//
// `props => <Comp foo="bar" {...props} />`
//
const App = () => (
<HTMLRenderer
html={html}
components={{
h1: props => <Heading color="red" {...props} />,
h2: Subheading,
a: Link,
}}
/>
)HTMLRenderer will render something that looks like the following:
;[
<Heading color="red">React</Heading>,
<Subheading>A JavaScript library for building user interfaces</Subheading>,
<p>
<Link to="#">Get Started</Link>
</p>,
]Component overrides
HTMLRenderer supports overriding components provided in the components prop
as needed. This can be utilized to create a reusable HTMLRenderer with a
default set of components throughout your project.
// src/components/HTML.js
import { Heading, Subheading, Link } from 'src/components'
export const HTML = props => (
<HTMLRenderer
components={{
h1: props => <Heading color="red" {...props} />,
}}
{...props}
/>
)The HTML component could be used by passing it an HTML string.
// src/pages/index.js
import { HTML } from 'src/components'
export const IndexPage = ({ html }) => <HTML html={html} />This will render H1 elements with red text.
If individual components need to be overridden, you can provide a mapping using
the componentOverrides prop.
// src/pages/index.js
import { HTML } from 'src/components'
export const IndexPage = ({ html }) => (
<HTML
html={html}
componentOverrides={{
h1: Comp => props => <Comp {...props} color="blue" />,
}}
/>
)This will render H1 elements with blue text.
Note that Comp is the Heading component defined in the original components
prop. This allows you to keep the existing component and modify it as needed.
Alternatively, you could disregard Comp and return a completely different
component.
