remark-code-jsx-renderer v1.1.10

remark-code-jsx-renderer

A remark plugin to render JSX code blocks using a custom renderer and components. This plugin is especially useful when you want to incorporate React JSX code directly into your Markdown documents and control how it's rendered.

Install

You can install the remark-code-jsx-renderer using npm or yarn:

npm i remark-code-jsx-renderer --save-dev
# or
yarn add remark-code-jsx-renderer --dev

Usage

To use this plugin, you need to incorporate it into your remark processing pipeline. Here's an example of how to do it:

Say we have the following file example.mdx:

This is some code:

```jsx renderable prettier
<Nav>
  <Nav.Item>
    <Nav.Link href='/features'>Features</Nav.Link>
  </Nav.Item>
  <Nav.Item>
    <Nav.Link href='/pricing'>Pricing</Nav.Link>
  </Nav.Item>
  <Nav.Item>
    <Nav.Link href='/about'>About</Nav.Link>
  </Nav.Item>
</Nav>
```

🚨 Important: The renderable attribute must be specified in code fence blocks for formatting the code.

And our module example.js looks as follows:

import { readFileSync } from 'node:fs'
import * as runtime from 'react/jsx-runtime'
import { Nav } from 'react-bootstrap'
import { renderToStaticMarkup } from 'react-dom/server'
import { remark } from 'remark'
import remarkCodeFormat from 'remark-code-format'
import remarkCodeJsxRenderer from 'remark-code-jsx-renderer'

const content = readFileSync('example.mdx', 'utf-8')

const file = await unified()
  .use(remarkCodeJsxRenderer, {
    ...runtime,
    components: { Nav },
    renderer: renderToStaticMarkup
  })
  .use(remarkCodeFormat, { htmlWhitespaceSensitivity: 'ignore' })
  .process(content)

console.log(String(file))

Now, running node example.js yields:

This is some code:

```html
<div class="nav">
  <div class="nav-item">
    <a href="/features" data-rr-ui-event-key="/features" class="nav-link">
      Features
    </a>
  </div>
  <div class="nav-item">
    <a href="pricing" data-rr-ui-event-key="pricing" class="nav-link">
      Pricing
    </a>
  </div>
  <div class="nav-item">
    <a href="about" data-rr-ui-event-key="about" class="nav-link">About</a>
  </div>
</div>
```

⚠️ This plugin offers support for inline options, specifically tailored to the unwrap option. With inline options, you have fine-grained control over the behavior of the unwrap feature.

```jsx renderable="{unwrap: true}"
// jsx code here
```

Options

This plugin accepts several options to customize its behavior:

components

An object where keys represent component names and values are React component types. These components are used for rendering JSX code blocks.

import { Alert, Button } from 'react-bootstrap'

processor.use(remarkCodeJsxRenderer, {
  components: { Alert, Button }
})

Fragment

Symbol to use for fragments. This option can be helpful if your JSX code specifically requires a particular type of Fragment.

import { Fragment } from 'react/jsx-runtime'

processor.use(remarkCodeJsxRenderer, { Fragment })

jsx

The jsx function to use when rendering JSX code. You can customize this function if your rendering process relies on a custom jsx implementation.

import { jsx } from 'react/jsx-runtime'

processor.use(remarkCodeJsxRenderer, { jsx })

jsxs

The jsxs function to use when rendering JSX code. Similar to jsx, this option allows you to customize the jsxs function if needed.

import { jsxs } from 'react/jsx-runtime'

processor.use(remarkCodeJsxRenderer, { jsxs })

renderer

A custom rendering function for rendering JSX code. This function should return a string. You can use this to render JSX using various methods, such as converting it to HTML or rendering it on the client-side.

import { renderToStaticMarkup } from 'react-dom/server'

processor.use(remarkCodeJsxRenderer, { renderer: renderToStaticMarkup })

sanitizer

The sanitizer option is an optional function that allows you to sanitize the JSX code before rendering. You can use this function to enhance security and prevent code injection.

import { renderToStaticMarkup } from 'react-dom/server'
import xss from 'xss'

processor.use(remarkCodeJsxRenderer, { sanitizer: customSanitizer })

// Sanitize the JSX code using the xss library
// you can replace it with any sanitizer you want (e.g. DOMPurify)
function sanitizeJSX(jsxCode) {
  const options = {
    // Define your custom xss options here
  }

  return xss(jsxCode, options)
}

unwrap

If true, the plugin will not wrap the rendered code in a codefence element.
