unist utility to remove positional info from a tree.
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: '.'}
]
}
]
}

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.
