## What it is
NodeJieba is the Node.js binding of the Jieba Chinese word segmentation library, with the core segmentation algorithms implemented in C++ via CppJieba for high performance. It supports multiple segmentation modes, custom and dynamic user dictionaries, and keyword extraction, and ships with full TypeScript type definitions.

## Use cases
- segment chinese text into words in a node.js application
- tokenize chinese sentences for search indexing
- extract keywords from chinese documents
- add custom domain-specific words to a chinese tokenizer
- cut chinese text with hmm model for out-of-vocabulary words
- preprocess chinese text for nlp pipelines in javascript

## When to choose
- you need fast, native-speed chinese word segmentation in a node.js or typescript project
- you want flexible dictionary loading with sensible defaults and optional custom user dictionaries
- you need multiple segmentation modes including full mode and search-engine mode
- you want to dynamically add words to the dictionary at runtime

## When to avoid
- you need segmentation for languages other than chinese
- you are working in python, go, or another runtime where the original jieba or a native binding is more idiomatic
- you cannot compile native c++ addons in your deployment environment
