nlcst utility to classify ASCII emoticons as EmoticonNodes.


What is this?

This utility searches for emoticons made with punctuation marks and symbols, and turns them into separate nodes.

When should I use this?

This package is a tiny utility that helps when dealing with plain-text emoticons in natural language. The plugin retext-emoji wraps this utility and others at a higher-level (easier) abstraction.


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

npm install nlcst-emoticon-modifier

In Deno with esm.sh:

import {emoticonModifier} from 'https://esm.sh/nlcst-emoticon-modifier@3'

In browsers with esm.sh:

<script type="module">
  import {emoticonModifier} from 'https://esm.sh/nlcst-emoticon-modifier@3?bundle'


import {emoticonModifier} from 'nlcst-emoticon-modifier'
import {ParseEnglish} from 'parse-english'
import {inspect} from 'unist-util-inspect'

const parser = new ParseEnglish()

const sentence = parser.parse('This makes me feel :).').children[0].children[0]

├─8 EmoticonNode ":)" (1:20-1:22, 19-21)
└─9 PunctuationNode "." (1:22-1:23, 21-22)


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


Merge emoticons in a SentenceNode into EmoticonNodes.


Nothing (undefined).


Emoticon node (TypeScript type).

import type {Data, Literal} from 'nlcst'

interface Emoticon extends Literal {
  type: 'EmoticonNode'
  data?: EmoticonData | undefined

interface EmoticonData extends Data {}


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

It also registers the Emoticon node type with @types/nlcst in SentenceContentMap. If you’re working with the syntax tree, make sure to import this utility somewhere in your types, as that registers the new node types in the tree.

 * @typedef {import('nlcst-emoticon-modifier')}

import {visit} from 'unist-util-visit'

/** @type {import('nlcst').Root} */
const tree = getNodeSomeHow()

visit(tree, function (node) {
  // `node` can now be a `Emoticon` node.


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, nlcst-emoticon-modifier@^3, compatible with Node.js 16.
