What is this?

This package is a unified (remark) plugin to turn links ([text](url)) and images (![alt](url)) into references ([text][id], ![alt][id]) and definitions ([id]: url).

When should I use this?

This project is useful when you want to transform markdown and prefer that it uses references and definitions. Long URLs in source code can make reading markdown difficult. References and definitions improve that by moving those URLs into definitions, outside of paragraphs.
This plugin is very similar to the alternative remark-reference-linksremark-reference-links. The difference is that that plugin generates numeric identifiers at the end of the document, whereas this plugin generates identifiers based on hostnames of URLs at the end of each section.
A different plugin, remark-inline-linksremark-inline-links, does the inverse: turn references and definitions into links and images.

Install

This package is ESM onlyesm. In Node.js (version 16+), install with npm:
npm install remark-defsplit

In Deno with esm.shesmsh:
import remarkDefsplit from 'https://esm.sh/remark-defsplit@5'

In browsers with esm.shesmsh:
<script type="module">
  import remarkDefsplit from 'https://esm.sh/remark-defsplit@5?bundle'
</script>

Use

Say we have the following file example.md:
# Pluto

[![Build](https://github.com/solar-system/pluto/workflows/main/badge.svg)](https://github.com/solar-system/pluto/actions)

## History

In the 1840s,
[Urbain Le Verrier](https://wikipedia.org/wiki/Urbain_Le_Verrier) used
Newtonian mechanics to predict the position of the then-undiscovered planet
[Neptune](https://wikipedia.org/wiki/Neptune) after analyzing perturbations
in the orbit of [Uranus](https://wikipedia.org/wiki/Uranus).

…and a module example.js:
import {remark} from 'remark'
import remarkDefsplit from 'remark-defsplit'
import {read} from 'to-vfile'

const file = await remark()
  .use(remarkDefsplit)
  .process(await read('example.md'))

console.log(String(file))

…then running node example.js yields:
# Pluto

👉 Note: observe that definitions are added at the end of each section and that IDs are generated based on the hostname of URLs.

API

This package exports no identifiers. The default export is remarkDefsplitapi-remark-defsplit.

unified().use(remarkDefsplit[, options])

Change links and images to references with separate definitions.
Parameters
— configuration
Returns
Transform (Transformerunified-transformer).

Options

Configuration (TypeScript type).
Fields
  • id (Array<string> or string, optional)
— IDs to use for new definitions instead of autogenerated ones;
when given one ID, then the first link or image will use that ID, when
another link or image is seen, it’ll get an autogenerated ID

Types

This package is fully typed with TypeScript. It exports the additional type Optionsapi-options.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.
When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, remark-defsplit@^5, compatible with Node.js 16.
This plugin works with unified version 6+ and remark version 7+.

Security

Use of remark-defsplit does not involve rehype (hast) or user content so there are no openings for cross-site scripting (XSS)wiki-xss attacks.
