This package is a utility that removes empty paragraphs, left over from other operations, from the tree. Paragraphs are considered empty if they do not contain non-whitespace characters.

Probably never! You should try to clean your trees yourself.

A plugin, remark-squeeze-paragraphs, exists that does the same but for remark.

This package is ESM only. In Node.js (version 16+), install with npm:

npm install mdast-squeeze-paragraphs

In Deno with esm.sh:

import {squeezeParagraphs} from 'https://esm.sh/mdast-squeeze-paragraphs@6'

In browsers with esm.sh:

<script type="module">
  import {squeezeParagraphs} from 'https://esm.sh/mdast-squeeze-paragraphs@6?bundle'
</script>

import {squeezeParagraphs} from 'mdast-squeeze-paragraphs'
import {u} from 'unist-builder'

const tree = u('root', [
  u('paragraph', []),
  u('paragraph', [u('text', 'Alpha')]),
  u('paragraph', [u('text', ' ')])
])

squeezeParagraphs(tree)

console.dir(tree, {depth: null})

Yields:

{ type: 'root',
  children:
   [ { type: 'paragraph',
       children: [ { type: 'text', value: 'Alpha' } ] } ] }

This package exports the identifier squeezeParagraphs. There is no default export.

Remove empty paragraphs in tree.

• tree (Node) — tree to change

Nothing (undefined).

This package is fully typed with TypeScript. It exports no additional types..

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, mdast-squeeze-paragraphs@^6, compatible with Node.js 16.

Use of mdast-squeeze-paragraphs does not involve hast or user content so there are no openings for cross-site scripting (XSS) attacks.

• remark-squeeze-paragraphs — remark plugin
• mdast-util-compact — make a tree compact
