ng-inifinte-autocomplete

AngularJS 1.x Wrapper for infinite-autocomplete library

Note: Whenever I mention the CORE, then I'm targeting the infinite-autocomplete library

Install

via npm:

$ npm i --save ng-infinite-autocomplete

via bower:

$ bower i -S ng-infinite-autocomplete

Developer section

In the package.json scripts we've 4 basic tasks:

build - Build the code once

build:watch - Build the code and watch changes

test - Run tests once

test:watch - Run tests and watch changes

Usage Example

import * as angular from 'angular';
import 'ng-infinite-autocomplete';
//or <script src="bower_components/ng-infinite-autocomplete/dist/index.js"></script>

//inject infinite-autocomplete as dependency for myApp module
angular.module('myApp', ['infinite-autocomplete'])
...

Controller:

  angular.module('myApp')
   .controller('MainCtrl', ['$http', '$q', function($http, $q){
   vm.onSelectHandler = function($element, $data) {
      console.log(arguments);
   }
   
    vm.data = [
                { text: 'Islam Attrash', value: 1},
                { text: 'Shai Reznik', value: 2},
                { text: 'Uri Shaked', value: 3},
                { text: 'Salsabel Eawissat', value: 4}
            ];
    vm.getData = function($text, $page, $fetchSize) {
        var deferred = $q.defer();
        $http.get("http://localhost:5000/data?text="+ $text + "&page=" + $page + "&fetchSize=" + $fetchSize)
          .then(function(res) {
              deferred.resolve(res.data);
          });
        return deferred.promise;
    }
   });

Template:

<div ng-controller="MainCtrl as vm">
  <!-- For Static data -->
  <ng-infinite-autocomplete
    data="vm.data"
    on-select="vm.onSelectHandler($element, $data)"
  ></ng-infinite-autocomplete>

  <!-- For external API -->
  <ng-infinite-autocomplete
    fetch-size="8"
    get-data-from-api="vm.getData($text, $page, $fetchSize)"
  ></ng-infinite-autocomplete>
</div>

Override Implementations

See this section on CORE, you pass a class via customizedInput, customizedOptions attributes

Directive Inputs/Outputs

  /**
   * current value
   */
  ngModel?: string;
  /**
   * data static source
   */
  data?:Array<IOption>;
  /**
   * on-select event output handler when choosing an option
   */
  onSelect?:Function($element, $data);
  /**
    * on-loading-state-change event output handler when choosing an option
    */
  onLoadingStateChange?($loadingState: boolean);
  /**
    * on-error event output handler when exception thrown
    */
  onError?(error: $error);
  /**
   * max height for the options
   */
  maxHeight?:string;
  /**
   * data dynamic api source
   */
  getDataFromApi?($text:string, $page:number, $fetchSize:number):es6Promise<Array<any>>;
  /**
   * Chunk fetch size
   */
  fetchSize?:number,
  /**
   * Customized input class to override the default input
   */
  customizedInput?:IInputCompoenentConstructor;
  /**
   * Customized options class to override the default input
   */
  customizedOptions?:IOptionsComponentConstructor;
  /**
   * treat data source as immutable - To improve $watch process
   */
   immutable?

Restrictions regards Attributes

• You must choose to pass data or getDataFromApi depends on whether the data is static or dynamic
• data attribute must be an array of { text: 'some text', value: 1}, and value could be any type (number, string, object..)
• max-height should be a string
• fetch-size should be a number
• customizedInput should extend InputComponent [For more See CORE]
• customizedOptions should extend OptionComponent [For more See CORE]

Directive Example

  <ng-infinite-autocomplete
            ng-model="vm.currentText"
            data="vm.data"
            immutable
            fetch-size="vm.fetchSize"
            on-select="vm.onSelectHandler($element, $data)"
            on-error="vm.onErrorHandler($error)"
            on-loading-state-change="vm.onLoadingStateChangeHandler($loadingState)"
            max-height="vm.maxHeight"
            customized-input="vm.CustomInput"
            customized-options="vm.CustomOptions">
  </ng-infinite-autocomplete>

This directive will use vm.data as a static data source, and the number of fetched data is vm.fetchSize in every scroll and/or search, the data will be treated as immutable and then you need to create new instance to update the options list for the autocomplete, it will run vm.onSelectHandler($element, $data) when selecting an option passing the clicked HTNLElement as the first argument and the data as the second one ({text: 'text', value: 'hi'}), and the maxmium height for the scrollable options will be vm.maxHeight (It will be overriden if not supplying enough scrollable area for options), and will use vm.CustomInput for implementing the input, and vm.CustomOptions for implementing the custom options also, loading states can be caught in vm.onLoadingStateChangeHandler and every exception will be passed to vm.onErrorHandler.

You can exclude any attribute not desired as you like following the restrictions mentioned above.
