Straightforward fuzzy matching, information retrieval and NLP building blocks for JavaScript.

Talisman is a JavaScript library collecting algorithms, functions and various building blocks for fuzzy matching, information retrieval and natural language processing.


You can install Talisman through npm:

npm install talisman

Source code

The library’s source code can be found on its Github repository.


  • Modular: the library is completely modular. This means that if you only need to compute a levenshtein distance, you will only load the relevant code.
  • Straightfoward & simple: just want to compute a jaccard index? No need to instantiate a class and use two methods to pass options and then finally succeed in getting the index. Just apply the jaccard function and get going.
  • Consistent API: the library’s API is fully consistent and one should not struggle to understand how to apply two different distance metrics.
  • Functional: except for cases where classes might be useful (clustering notably), Talisman only uses functions, consumes raw data and order functions’ arguments to make partial application & currying etc. as easy as possible.
  • Performant: the library should be as performant as possible for a high-level programming language library.
  • Cross-platform: the library is cross-platform and can be used both with node.js and in the browser.
