character-entities-legacy

library3.0.0jsnpmunverified

A list of legacy HTML named character references that do not require a trailing semicolon (e.g., &copy works for ©). This package provides a single exported array of entity names (without the ampersand or semicolon) that historically are allowed without the semicolon in HTML. Version 3.0.0 is ESM-only, fully typed with TypeScript, and requires Node.js 12.20+, 14.14+, or 16.0+. It is a focused utility for HTML parsers and minifiers; use parse-entities or stringify-entities for broader entity handling.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

characterEntitiesLegacy

✓ import { characterEntitiesLegacy } from 'character-entities-legacy'

✗ const characterEntitiesLegacy = require('character-entities-legacy')

ESM-only since v3; CommonJS require will fail. The array is case-sensitive; entity names are without '&' or ';'.

(default export)

✓ import { characterEntitiesLegacy } from 'character-entities-legacy'

✗ import characterEntitiesLegacy from 'character-entities-legacy'

There is no default export; only a named export is available.

TypeScript usage

✓ import { characterEntitiesLegacy } from 'character-entities-legacy'

✗ import { characterEntitiesLegacy } from 'character-entities-legacy' with types assertion

Types are bundled; no additional type package needed.

Shows how to import and use the legacy entity names array, checking membership and array properties.

import { characterEntitiesLegacy } from 'character-entities-legacy' console.log(characterEntitiesLegacy.includes('copy')) // true console.log(characterEntitiesLegacy.includes('frac34')) // true console.log(characterEntitiesLegacy.includes('sup1')) // true console.log(Array.isArray(characterEntitiesLegacy)) // true console.log(characterEntitiesLegacy.length) // number of entities

Debug

Known issues

breakingPackage is ESM-only starting from version 3.0.0. CommonJS require() will throw.

fix

Use ESM import or upgrade to Node.js 12+ and use 'import' syntax.

affects: >=3.0.0

gotchaThe entity names are case-sensitive and do not include the leading '&' or trailing ';'.

fix

Use lowercase strings without punctuation (e.g., 'copy', not '&copy' or '&copy;').

affects: all

gotchaOnly legacy entities that do not require a semicolon are included; modern entities are in the companion package character-entities.

fix

Use character-entities for full list, or parse-entities for parsing.

affects: all

Errors

Common errors & fixes

require is not defined in ES module scope

Trying to use require() in an ESM-only package.

fix

Change to import { characterEntitiesLegacy } from 'character-entities-legacy' and ensure package.json has 'type': 'module'.

Cannot find module 'character-entities-legacy'

Package not installed or import path incorrect.

fix

Run 'npm install character-entities-legacy' and use correct import syntax.

characterEntitiesLegacy.includes is not a function

Importing default instead of named export, or using wrong variable.

Use 'import { characterEntitiesLegacy } from 'character-entities-legacy'' (named export).
