unist-util-find-all-after
Advanced tools
The `unist-util-find-all-after` package is a utility for working with unist syntax trees. It allows you to find all nodes that come after a specified node in a tree, which can be useful for various tree manipulations and traversals.
Find all nodes after a given node
This feature allows you to find all nodes that come after a specified node in a unist tree. In this example, it finds all nodes that come after the first paragraph node.
const findAllAfter = require('unist-util-find-all-after');
const tree = {
type: 'root',
children: [
{ type: 'paragraph', value: 'First paragraph' },
{ type: 'paragraph', value: 'Second paragraph' },
{ type: 'paragraph', value: 'Third paragraph' }
]
};
const node = tree.children[0];
const result = findAllAfter(tree, node);
console.log(result);
Find all nodes of a specific type after a given node
This feature allows you to find all nodes of a specific type that come after a specified node in a unist tree. In this example, it finds all heading nodes that come after the first paragraph node.
const findAllAfter = require('unist-util-find-all-after');
const tree = {
type: 'root',
children: [
{ type: 'paragraph', value: 'First paragraph' },
{ type: 'heading', value: 'First heading' },
{ type: 'paragraph', value: 'Second paragraph' }
]
};
const node = tree.children[0];
const result = findAllAfter(tree, node, 'heading');
console.log(result);
The `unist-util-visit` package is used to recursively walk through unist syntax trees. It allows you to visit nodes based on their type and perform actions on them. Unlike `unist-util-find-all-after`, which focuses on finding nodes after a specific node, `unist-util-visit` is more general-purpose and can be used for a variety of tree traversal tasks.
The `unist-util-select` package provides a CSS-like selector API for unist syntax trees. It allows you to query nodes in a tree using selectors, making it more flexible for complex queries compared to `unist-util-find-all-after`, which is more straightforward and focused on finding nodes after a specific point.
unist utility to find nodes after another node.
This is a tiny utility that you can use to find nodes after another node or before an index in a parent.
This is super tiny. You can of course do it yourself. But this helps when integrating with the rest of unified and unist.
This package is ESM only. In Node.js (version 16+), install with npm:
npm install unist-util-find-all-after
In Deno with esm.sh
:
import {findAllAfter} from 'https://esm.sh/unist-util-find-all-after@5'
In browsers with esm.sh
:
<script type="module">
import {findAllAfter} from 'https://esm.sh/unist-util-find-all-after@5?bundle'
</script>
import {u} from 'unist-builder'
import {findAllAfter} from 'unist-util-find-all-after'
const tree = u('tree', [
u('leaf', 'leaf 1'),
u('parent', [u('leaf', 'leaf 2'), u('leaf', 'leaf 3')]),
u('leaf', 'leaf 4'),
u('parent', [u('leaf', 'leaf 5')]),
u('leaf', 'leaf 6'),
u('empty'),
u('leaf', 'leaf 7')
])
console.log(findAllAfter(tree, 1, 'leaf'))
Yields:
[
{type: 'leaf', value: 'leaf 4'},
{type: 'leaf', value: 'leaf 6'},
{type: 'leaf', value: 'leaf 7'}
]
This package exports the identifier findAllAfter
.
There is no default export.
findAllAfter(parent, child|index[, test])

or before an index, that pass

This package is fully typed with TypeScript.
It exports no additional types (types for the test are in unist-util-is
).
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-find-all-after@^5
, compatible with Node.js 16.
