Fuse.js is a lightweight, zero-dependency fuzzy-search library written in TypeScript that runs in the browser, Node.js, and Deno. It uses the Bitap algorithm for typo-tolerant matching over small-to-medium JSON datasets, with weighted keys, extended/logical query operators, token search, and optional Web Worker parallelism.

Use cases

• add typo-tolerant search to a client-side list of items
• fuzzy search a JSON array in the browser without a backend
• search small-to-medium datasets where no dedicated search server exists
• rank search results across weighted object fields
• run multi-word fuzzy queries with relevance ranking
• search large datasets without blocking the UI using web workers

When to choose

• you need client-side fuzzy search with zero dependencies and tiny bundle size
• your dataset is small-to-medium and you cannot run a search backend
• you want typo tolerance, weighted fields, and logical query operators in one library
• you need the same search to work in browser, Node.js, and Deno

When to avoid

• you need to index millions of documents or scale search across servers
• you need full-text search features like stemming, faceting, or highlighting
• you already run a dedicated search engine like Elasticsearch or Meilisearch
