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
