unist utility to pretty print the positional info of a node.


What is this?

This package is a utility that takes any unist (whether mdast, hast, etc) node, position, or point, and serializes its positional info.

When should I use this?

This utility is useful to display where something occurred in the original document, in one standard way, for humans. For example, when throwing errors or warning messages about something.


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

npm install unist-util-stringify-position

In Deno with esm.sh:

import {stringifyPosition} from 'https://esm.sh/unist-util-stringify-position@3'

In browsers with esm.sh:

<script type="module">
  import {stringifyPosition} from 'https://esm.sh/unist-util-stringify-position@3?bundle'


import {stringifyPosition} from 'unist-util-stringify-position'

stringifyPosition({line: 2, column: 3}) // => '2:3' (point)
stringifyPosition({start: {line: 2}, end: {line: 3}}) // => '2:1-3:1' (position)
  type: 'text',
  value: '!',
  position: {
    start: {line: 5, column: 11},
    end: {line: 5, column: 12}
}) // => '5:11-5:12' (node)


This package exports the identifier stringifyPosition. There is no default export.


Serialize the positional info of a point, position (start and end points), or node.


Pretty printed positional info of a node (string).

In the format of a range ls:cs-le:ce (when given node or position) or a point l:c (when given point), where l stands for line, c for column, s for start, and e for end. An empty string ('') is returned if the given value is neither node, position, nor point.


This package is fully typed with TypeScript. It exports no additional types.


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.
