Usage and API reference

unist-util-inspect

unist utility to inspect trees.

Contents

What is this?

This is a utility pretty prints the tree.

When should I use this?

This utility pretty prints the tree in a format that is made custom for unist trees, which is terser than the often verbose and repetitive JSON, to more easily spot bugs and see what’s going on in the tree.

Install

This package is ESM only. In Node.js (version 14.14+ and 16.0+), install with npm:

npm install @stackline/unist-util-inspect

In Deno with esm.sh:

import {inspect} from 'https://esm.sh/unist-util-inspect@7'

In browsers with esm.sh:

<script type="module">
  import {inspect} from 'https://esm.sh/unist-util-inspect@7?bundle'
</script>

Use

import {u} from 'unist-builder'
import {inspect} from '@stackline/unist-util-inspect'

const tree = u('root', [
  u('literal', '1'),
  u('parent', [
    u('void', {id: 'a'}),
    u('literal', '2'),
    u('node', {id: 'b'}, [])
  ])
])

console.log(inspect(tree))

Yields:

root[2]
├─0 literal "1"
└─1 parent[3]
    ├─0 void
    │     id: "a"
    ├─1 literal "2"
    └─2 node[0]
          id: "b"
