trie-search is a JavaScript/TypeScript library implementing a Trie (prefix tree) data structure for efficient string-based object lookup. It enables mapping string keys to objects and retrieving all objects whose keys match a given prefix. The library supports features like case-insensitive search, customizable tokenization via regex, international character handling, caching of search results, and flexible result combination through a reducer pattern. Designed for use in autocomplete/typeahead interfaces, it indexes objects by breaking keys into character trees and returns all objects in subtrees matching the search prefix. The architecture centers around a TrieSearch class with methods for adding, removing, and searching items, using nested objects for internal node representation and hasharray/md5 dependencies for caching and ID generation.
