What is this?

This utility serializes a node and cleans it.

When should I use this?

This package is a tiny utility that helps when comparing natural language to word lists.

Install

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

npm install nlcst-normalize

In Deno with esm.sh:

import {normalize} from 'https://esm.sh/nlcst-normalize@4'

In browsers with esm.sh:

<script type="module">
  import {normalize} from 'https://esm.sh/nlcst-normalize@4?bundle'
</script>

Use

import {normalize} from 'nlcst-normalize'

normalize("Don't") // => 'dont'
normalize('Don’t') // => 'dont'
normalize('Don’t', {allowApostrophes: true}) // => 'don\'t'
normalize('Block-level') // => 'blocklevel'
normalize('Block-level', {allowDashes: true}) // => 'block-level'

normalize({
  type: 'WordNode',
  children: [
    {type: 'TextNode', value: 'Block'},
    {type: 'PunctuationNode', value: '-'},
    {type: 'TextNode', value: 'level'}
  ]
}) // => 'blocklevel'

API

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

normalize(value[, options])

Normalize a word for easier comparison.

Always normalizes smart apostrophes (’) to straight apostrophes (') and lowercases alphabetical characters ([A-Z]).

Parameters

• value (Array<Node>, Node, or string) — word
• options (Options, optional) — configuration

Returns

Normalized word (string).

Options

Configuration (TypeScript type).

Fields

• allowApostrophes (boolean, default: false) — do not strip apostrophes ('); the default is to remove apostrophes
• allowDashes (boolean, default: false) — Do not strip hyphens (-); the default is to remove the hyphen-minus character

Types

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

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. This means we try to keep the current release line, nlcst-normalize@^4, compatible with Node.js 16.
