In almost all mobile and web apps being able to search is one of the most important parts. Autocomplete is an option that can save you keystrokes by automatically filling in HTML elements & attributes. As we start typing in our query, it give suggestions which we can choose from. Once we select the desired option, the selected text is displayed in the field. So here are 20 Autocomplete & Autosuggest Javascript Libraries that will assist in query creation, reduce keystrokes and help avoid typos.

Typeahead.js

Inspired by twitter.com’s autocomplete search functionality, typeahead.js is a flexible JavaScript library that provides a strong foundation for building robust typeaheads. The typeahead.js library consists of 2 components: the suggestion engine, Bloodhound, and the UI view, Typeahead. The suggestion engine is responsible for computing suggestions for a given query. The UI view is responsible for rendering suggestions and handling DOM interactions. Both components can be used separately, but when used together, they can provide a rich typeahead experience.
