break line in mdx

When rendering Markdown content in an MDX file using Contentlayer in a Next.js project, line breaks (or new lines) depend on the Markdown syntax you use and how your MDX parser handles it. Below are the key methods to achieve line breaks:

1. Double Space for Line Breaks

In Markdown, inserting two spaces at the end of a line will create a line break.

Example:

This is the first line.  
This is the second line.

Output:

This is the first line.
This is the second line.

2. Use <br /> Tag

You can use an HTML <br /> tag within your Markdown content for explicit line breaks. This method is especially helpful if the double-space approach doesn't work as expected.

Example:

This is the first line.<br />
This is the second line.

Output:

This is the first line.
This is the second line.

3. Ensure Proper MDX Renderer Configuration

If line breaks are not rendering as expected, check the MDX rendering setup in your project. In Contentlayer, MDX content is rendered via a React-based MDX runtime. Ensure your configuration supports Markdown syntax:

• If using @contentlayer/client with MDX, confirm the Markdown-to-MDX pipeline handles line breaks appropriately.
• Ensure the remark-gfm plugin is installed and configured to enable GitHub Flavored Markdown (GFM), which includes support for soft line breaks.

Install the plugin:

npm install remark-gfm

Configure contentlayer.config.ts:

import { defineDocumentType, makeSource } from 'contentlayer/source-files'
import remarkGfm from 'remark-gfm'

export default makeSource({
  contentDirPath: 'content',
  documentTypes: [/* Your Document Types */],
  mdx: {
    remarkPlugins: [remarkGfm],
  },
})

4. Soft Line Breaks

For soft line breaks (single newlines without breaking into a new paragraph), ensure your Markdown respects GFM conventions.

Example:

This is the first line
This is the second line.

With GFM enabled, this will render as:

This is the first line This is the second line.

To break into separate lines, add two spaces or use <br />.

Summary

• Double spaces at the end of a line for a break.
• Use <br /> for explicit line breaks.
• Enable remark-gfm to handle advanced Markdown features.
