This is a utility pretty prints the tree.

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.

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

npm install unist-util-inspect

In Deno with esm.sh:

import {inspect} from 'https://esm.sh/unist-util-inspect@8'

In browsers with esm.sh:

<script type="module">
  import {inspect} from 'https://esm.sh/unist-util-inspect@8?bundle'
</script>

import {u} from 'unist-builder'
import {inspect} from '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"

This package exports the identifiers inspect, inspectColor, and inspectNoColor. There is no default export.

Inspect a tree.

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

Pretty printed tree (string).

🪦 Deprecated: use color option of inspect.

Inspect a tree, with color. Otherwise same as inspect.

🪦 Deprecated: use color option of inspect.

Inspect a tree, without color. Otherwise same as inspect.

Configuration (TypeScript type).

• color (boolean, default: true in Node, false otherwise) — whether to use ANSI colors
• showPositions (boolean, default: true) — whether to include positional information

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-inspect@^8, compatible with Node.js 16.
