markdown-react-renderer v2.1.0

React component for rendering Markdown strings to components.

Install

yarn add markdown-react-renderer

Usage

Provide a map of components to Markdown. The map will take valid HTML tags as keys.

import React from 'react'
import { MarkdownRenderer } from 'markdown-react-renderer'

// Components to which elements are mapped
import Heading from './Heading'
import Subheading from './Subheading'
import Link from './Link'

// Markdown to render as React components
const markdown = `
  # React
  ## A JavaScript library for building user interfaces.
  [Get started](https://reactjs.org/docs/getting-started.html)
`

const App = () => (
  <MarkdownRenderer
    markdown={markdown}
    components={{
      h1: props => <Heading color="red" {...props} />,
      h2: Subheading,
      a: Link,
    }}
  />
)

<MarkdownRenderer> will render the following:

<>
  <Heading color="red">React</Heading>
  <Subheading>A JavaScript library for building user interfaces.</Subheading>
  <p>
    <Link href="https://reactjs.org/docs/getting-started.html">
      Get started
    </Link>
  </p>
</>

Component overrides

MarkdownRenderer supports overriding components provided in the components prop as needed. This can be utilized to create a reusable MarkdownRenderer with a default set of components throughout your project.

// src/components/Markdown.js

import { Heading, Subheading, Link } from 'src/components'

export const Markdown = props => (
  <MarkdownRenderer
    components={{
      h1: props => <Heading color="red" {...props} />,
    }}
    {...props}
  />
)

The Markdown component could be used by passing it a Markdown string.

// src/pages/index.js

import { Markdown } from 'src/components'

export const IndexPage = ({ markdown }) => <Markdown markdown={markdown} />

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 { Markdown } from 'src/components'

export const IndexPage = ({ markdown }) => (
  <Markdown
    markdown={markdown}
    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.
