## What it is
A modern, tree-shakable TypeScript/JavaScript library for manipulating Korean Hangul characters. It provides APIs for initial consonant (choseong) search, particle (josa) attachment, syllable decomposition/assembly, keyboard conversion, number-to-Hangul, pronunciation, and romanization.

## Use cases
- implement korean initial consonant search
- attach correct korean particles to words
- disassemble hangul into jamo components
- convert hangul to qwerty and back
- spell korean numbers in hangul
- romanize korean text
- standardize korean pronunciation in text

## When to choose
- building Korean-facing web or Node.js apps needing Hangul text processing
- you want a lightweight, tree-shakable, strongly typed alternative to Hangul.js
- you need search matching on initial consonants typed by users

## When to avoid
- your project does not handle Korean text
- you need full NLP like morphological analysis or machine translation
- you work outside the JavaScript/TypeScript ecosystem

## Facets
- artifact type: library
- maturity: active
- function: nlp, parser, serialization
- domain: web-development, developer-tools
- platform: browser, cross-platform
- tags: korean, hangul, text-processing, typescript, tree-shakable, choseong-search, josa, korean-language-processing, natural-language-processing, localization, nodejs, web-server
