Twitter typeahead.js is a fast and battle-tested jQuery plugin for auto completion. Today we’re open sourcing the code on GitHub under the MIT license. By sharing a piece of our infrastructure with the open source community, we hope to evolve typeahead.js further with community input.
If your web application needs a fully-featured queryable search box, typeahead.js can help. Some of its capabilities and features include:
It’s also optimized for large local datasets, so it’s fast for high-latency networks.
We recommend you take a look at our examples page. There are three ways to get data:
Using local, hard-coded data passed on page render:
local: [ "Mercury", "Venus", "Earth", "Mars", "Jupiter", "Saturn", "Uranus", "Neptune" ]
Using a prefetch URL that will be hit to grab data on pageload and then stored in localStorage:
Or using a queryable API that returns results as-you-type (with the query being passed in the ?q= parameter):
You can also combine local or prefetch with a remote fallback for the performance of local data combined with the coverage of a remote query API (e.g. quickly search your friends but be able to find anyone on your site). There are lots of options for configuring everything from ranking, matching, rendering, templating engines, and more; check out the README for those details.
We initially built typeahead.js to support our needs; now we look forward to improvements and suggestions from the community. To learn more about how typeahead.js works, check out our detailed documentation. To stay in touch, follow @typeahead and submit issues on GitHub.
