export class MyViewModel {

  results     = [];
  attributes  = ['productName', 'barcode'];
  customLabel = product => product.name + product.barcode;
  value       = 'banana';
  productCriteria = {
    stock: {'>': 0}
  };
  defaultProduct = {
    productName: 'No product',
    productCategory   : 'none'
  };

  constructor() {
    product = this.defaultProduct;
  }

  resultsChanged(products) {
    // select the first product that has the name 'banana'. If cannot be found
    // then select the first product in the results.
    this.selected = products.find(product => product.name === 'banana') || products[0];

    // always show the no product option
    this.results = this.results.concat([this.defaultProduct]);
  }

  productSort(products) {
    products.sort((a, b) => a.price > b.price;
  }

}

  <h4>${product.productName} ${product.productCategory}</h4>

Methods

Some methods might be handy to overwrite or wrap.

shouldPerformRequest()

When it returns true, a request will be performed on a search change.

findResults(query)

Overwrite the default fetch. Expects to return a Promise which resolves to a list of results

searchQuery(string)

By default aurelia autocomplete works with waterline queries. If your query language differs, you can overwrite this method to return a query your endpoint accepts.

filter(items)

Takes items and returns only the array defined in the items bindable and should returns a new array containing the desired array with results.

By default it makes sure to not return more items than the limit specifies.

itemMatches(item)

Used by the this.filter to determine if an item should be added or not.

get regex()

Returns a regex which is used for highlighting the items in the html and for determining if an item matches in the itemMatches method
