Overview

## What does typeahead.js do?

## **What is typeahead.js?**

typeahead.js is an open-source autocomplete library originally created by Twitter's engineering team. It provides fast, flexible autocomplete features with support for multiple datasets, suggestion templates, and prefetching. The library takes an input element and a dataset (either local or from a remote endpoint) and renders autocomplete suggestions as the user types. It operates entirely client-side.

## **GDPR and typeahead.js**

typeahead.js itself has no GDPR implications. If it queries a remote endpoint, GDPR applies to what data that endpoint receives and returns, not to typeahead.js. If users can search for or find personal data via typeahead, access controls on the search endpoint are required.

## **Practical compliance steps**

No GDPR actions needed for typeahead.js. Install via npm. Secure any remote endpoint used for suggestions. Note that typeahead.js is no longer actively maintained. Autocomplete.js or downshift are modern alternatives.
