The backbone of ngAtp is ngBloodhound, which is almost entirely adopted from twhitbeck's angular-bloodhound, an Angular port of Twitter's Bloodhound.

Quick Start

Include dist/js/ng-atp-bundle.js or dist/js/ng-atp-bundle.min.js on your page after angular and lodash¹ (or use as a bower component: bower install ng-atp).

[1] lodash is no longer a dependency

• For CommonJS:

var _ = require('lodash');
var angular = require('angular');
require('ng-atp');  // exports angular.module('ng-atp')

Use:

Update:

Added in config options: completeOn. Default Value : { tab: true, rightArrow: true }. Can be used to fine-tune whether to autocomplete on tab or right arrow key.

<div ng-atp="city" ng-atp-config="cityAutocompleteOpts">
    <input ng-atp-input />
    <ul ng-atp-suggestions>
    </ul>
</div>

Set ng-atp attribute value to the variable in scope you'd like to autocomplete for, same way you'd use a ngModel directive. Pass Bloodhound config object using ng-atp-config attribute. Additonal config options: idAttribute, specify the key/id attribute to use for tracking suggestion items (similar to track by for ng-repeat). Also, you should to supply two functions in config: format and verify(optional). format is expected to be a function that takes a suggestion datum (eg. { label: "Thing", id: 1}) into a string to display, and verify is expected to be a function that takes a single suggestion datum as an argument, and returns a boolean (be sure to return false for null).

In addition, ng-atp-suggestions allows you to use custom template by suppling an attribute template-url. template-url should point to a valid Angular template for a single suggestion item (which will be wrapped inside a <li> tag), and ng-atp-suggestions expose the scope variable suggestion for your template, as well as setting the class of the corresponding item to "selected" from user interactions (hover, and arrow key press). An example template may look like this:

<ul ng-atp-suggestions template-url="partials/mytemplate.html">

mytemplate.html:

<div>
  <i class="fa {{ suggestion.icon }}"></i>
  <span>{{ suggestion.label }}</span>
  <img src="{{ suggestion.url }}">
</div>

Details

ngAtp implements Twitter Bloodhound as a Angular service, ngBloodhound uses Angular's $http service as opposed to jQuery $.ajax in the original version (inspired by twhitbeck/angular-bloodhound). Other than that, suggestions are entirely managed by Bloodhound with all its prefetching, intelligent caching, fast lookups, and backfilling. On the rendering/directive side of things, ngAtp relies on ng-model and ng-repeat (without filtering, which is handled by Bloodhound), and tries to stick to default Angular directives as much as possilbe.
