## What is this?
This package is a [unified][] ([retext][]) plugin to add part of speech tags
to words.
It uses [`dariusk/pos-js`][posjs] and adds `node.data.partOfSpeech` on
[`Word`][nlcst-word] nodes.
It works by checking each sentence, so its smarter that just passing one word
through.
## When should I use this?
You can either use this plugin if another plugin, or your own plugin, needs
POS tags!
## Install
This package is [ESM only][esm].
In Node.js (version 16+), install with [npm][]:
```sh
npm install retext-pos
```
In Deno with [`esm.sh`][esmsh]:
```js
import retextPos from 'https://esm.sh/retext-pos@5'
```
In browsers with [`esm.sh`][esmsh]:
```html
import retextPos from 'https://esm.sh/retext-pos@5?bundle'
```
## Use
```js
/**
* @typedef {import('nlcst').Root} Root
*/
import {retext} from 'retext'
import retextPos from 'retext-pos'
import {inspect} from 'unist-util-inspect'
await retext()
.use(retextPos)
.use(myRetextPlugin)
.process('I went to the store, to buy 5.2 gallons of milk.')
function myRetextPlugin() {
/**
* @param {Root} tree
*/
return function (tree) {
console.log(inspect(tree))
}
}
```
Yields:

## Compatibility
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.
