snowball-stemmers-js

Snowball stemmers compiled to JavaScript — 38 algorithms, zero runtime dependencies, auto-rebuilt whenever snowball publishes a new release.

The algorithms are the canonical Snowball stemmers (BSD-3-Clause), generated by the snowball compiler at build time — not a hand-maintained port.

Usage

const { newStemmer, stem } = require("snowball-stemmers-js")

newStemmer("english").stemWord("installing")   // "instal"
stem("de", "Häusern")                          // "Haus"
stem("fr", "installations")                    // "install"

Languages accept the snowball algorithm name ("german") or the common ISO-639-1 code ("de"). All 38 algorithms:

arabic, armenian, basque, catalan, czech, danish, dutch, dutch_porter, earlymodernenglish, english, esperanto, estonian, finnish, french, german, greek, hindi, hungarian, indonesian, irish, italian, lithuanian, lovins, nepali, norwegian, persian, polish, porter, portuguese, romanian, russian, serbian, sesotho, spanish, swedish, tamil, turkish, yiddish

How it stays current

A daily workflow compares snowball's latest tag against the pinned SNOWBALL_REF; when snowball releases, it rebuilds the JavaScript, bumps the package version to match, commits, and tags — the Release workflow then publishes to npm with provenance.
