This is a small utility that helps you remove the position field from nodes in a unist tree.

Often, positional info is the whole reason, or an important reason, for using ASTs. Sometimes, especially when comparing trees, or when inserting one tree into another, the positional info is at best useless and at worst harmful. In those cases, you can use this utility to remove position fields from a tree.

You might find the utility unist-util-position useful to instead get clean position info from a tree, or unist-util-generated useful to check whether a node is considered to be generated (not in the original input file).

You might also enjoy unist-util-stringify-position when you want to display positional info to users.

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

npm install unist-util-remove-position

In Deno with esm.sh:

import {removePosition} from 'https://esm.sh/unist-util-remove-position@5'

In browsers with esm.sh:

<script type="module">
  import {removePosition} from 'https://esm.sh/unist-util-remove-position@5?bundle'
</script>

import {fromMarkdown} from 'mdast-util-from-markdown'
import {removePosition} from 'unist-util-remove-position'

const tree = fromMarkdown('Some _emphasis_, **importance**, and `code`.')

removePosition(tree, {force: true})

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

Yields:

{
  type: 'root',
  children: [
    {
      type: 'paragraph',
      children: [
        {type: 'text', value: 'Some '},
        {type: 'emphasis', children: [{type: 'text', value: 'emphasis'}]},
        {type: 'text', value: ', '},
        {type: 'strong', children: [{type: 'text', value: 'importance'}]},
        {type: 'text', value: ', and '},
        {type: 'inlineCode', value: 'code'},
        {type: 'text', value: '.'}
      ]
    }
  ]
}

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

Remove the position field from a tree.

• node (Node) — tree to clean
• options (Options, optional) — configuration

Nothing (undefined).

Configuration (TypeScript type).

• force (boolean, default: false) — whether to use delete to remove position fields, the default is to set them to undefined

This package is fully typed with TypeScript. It exports the additional type Options.

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, unist-util-remove-position@^5, compatible with Node.js 16.
