eslint-plugin-spellcheck

ESLint plugin (v0.0.20, last updated 2022, low release cadence) that checks spelling in identifiers, strings, comments, and templates of JavaScript files using Hunspell dictionaries. Supports multiple English locales (en_US, en_CA, en_AU, en_GB), custom skip words, regex pattern exclusions, and minimum word length. The plugin is lightweight but infrequently maintained; it has no security incidents but the underlying hunspell-spellchecker dependency (v0.4.1) is dated. Alternative with more active development: eslint-plugin-spellcheck (different package) or cspell.
