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 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 '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"

API

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

inspect(tree[, options])

Inspect a tree, with color in Node, without color in browsers.

Parameters

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

Returns

Pretty printed tree (string).

inspectColor(tree[, options])

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

inspectNoColor(tree[, options])

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

Options

Configuration (TypeScript type).

Fields

• showPositions (boolean, default: true) — whether to include positional information

Types

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

Compatibility

Projects maintained by the unified collective are compatible with all maintained versions of Node.js. As of now, that is Node.js 14.14+ and 16.0+. Our projects sometimes work with older versions, but this is not guaranteed.

Upstream issues and maintenance review

Upstream and maintenance review

This package maintains unist-util-inspect@7.0.2 under the independent @stackline/unist-util-inspect name.

• Source: https://github.com/syntax-tree/unist-util-inspect/tree/04775f5f5af91c1ba3dc81cadf957b4abd49642e
• Public npm artifact integrity: sha512-Op0XnmHUl6C2zo/yJCwhXQSm/SmW22eDZdWP2qdf4WpGrgO1ZxFodq+5zFyeRGasFjJotAnLgfuD1jkcKqiH1Q==.
• Upstream issue evidence checked: 2026-09-29T00:22:11.437550+00:00.
• Original license and author notices are retained.
• The upstream published runtime files and declarations are hash-checked in .stackline/upstream.json. Any runtime fix is explicitly listed there.
• Functional upstream suites run against the source and extracted final package. Development tools were reduced to those used by validation; full source and runtime audits must pass.
• Only direct dependencies of the original Stackline portfolio are in this migration. This is not a claim that all transitive projects are maintained by Stackline.

Issue triage

The queried open-issue list contained no issue entries. This does not establish that the upstream is abandoned or bug-free. No runtime bug fix is claimed for this initial maintenance release.

The evidence query fetched the latest 100 open and 30 closed issue/PR entries and removed PRs. Closed entries were collected for context; this report does not claim an exhaustive historic review.

Release discipline

The source commit, passing CI and CodeQL, reviewed CI tarball hash, npm provenance, normal and aliased installs, and immutable GitHub release are checked before a release is complete. Published versions and tags are never replaced.

Release changes
