retext plugin to add part-of-speech (POS) tags.

Useful for other plugins as it adds information to nlcst nodes.

Install

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required.

npm:

npm install retext-pos

Use

import {retext} from 'retext'
import {inspect} from 'unist-util-inspect'
import retextPos from 'retext-pos'

retext()
  .use(retextPos)
  .use(() => (tree) => {
    console.log(inspect(tree))
  })
  .process('I went to the store, to buy 5.2 gallons of milk.')

Yields:
