Widget

Widgets allow you to easily embed shopping list tools on your recipe site. Widgets provide options to add recipes to shopping list or basket and to view the shopping list. Widgets are tied to a specific recipe. In order for widget to appear your current page URL must be a recipe. Or you can specify recipeUrlto link different or multiple recipes on the same page.

Defining widget

Widget builder

The easiest way to add a widget is to use our widget builder. It automatically generates code and allows you to configure various options.

Manually define widget

Use whisk.shoppingList.defineWidget(id, options) function to define widget.

  • id is a string that must be unique for every widget on a single page and must match the container's id attribute.

  • options parameter is optional and describes how your widget will look and behave. See a list of supported options below.

The next step is to display your previously defined widget on the page. Use display method like so:

whisk.queue.push(function() {
  whisk.shoppingList.defineWidget('widget-id', {
    recipeUrl: 'optional recipe url',
    styles: {
      size: 'large',
      type: 'modal',
    },
  });
});

The result should look like this:

Testing

The widget supports the hidden option so you can test the integration before making it publicly available. Add hidden: true to options and widget will be hidden by default. To see widget add whisk-enable=1 query parameter to URL (i.e. https://example.com/my-recipe-url?whisk-enable=1).

Multiple recipes

In order to show multiple recipes and widgets on the same page:

  • Each recipe must have its own URL that must be recognized by the recipe validator.

  • Use the same code as above for every recipe on page with recipeUrl option.

  • Make sure IDs are unique for every widget.

Widget not appearing

In case your widget is not appearing:

  • Make sure your recipe URL is recognized by the recipe validator.

  • If you use hidden: true make sure whisk-enable=1 query parameter is set.

Subscriptions

Read general information about subscriptions here. Widgets support the following event types:

  • view - widget appeared in the viewport. Triggered once. No custom data for this event type.

  • click - widget button has been clicked. data has the following structure:

  • error - triggered when the widget has failed to load. It can be caused by the recipe not being recognized, network error, etc. No custom data for this event type.

AMP integration

Adding widget to your AMP pages is done via amp-iframe technology. In order to integrate Whisk on your page follow the instructions below.

Add amp-iframe script inside the <head> of your page:

<script async custom-element="amp-iframe" src="https://cdn.ampproject.org/v0/amp-iframe-0.1.js"></script>
Add the following code where you want the widget to appear on your page. Please note that there are some amp-iframe positioning limitations: learn more. Replace recipe-url with your actual recipe url. You should use canonical url (a.k.a. non-amp url of your recipe page).
<amp-iframe height="225"
  sandbox="allow-scripts allow-same-origin allow-popups allow-forms"
  frameborder="0"
  src="https://cdn.whisk.com/sdk/amp.html?recipe-url=https://whisk.com/demo/sponsored-ingredient">
</amp-iframe>

Open this page on your mobile phone to see how it works.

Styling notes

  • In order to add margins to the widget add margin property to the iframe (for example: style="margin: 0 10px").

  • If you are one of our partners who have their own white-label, please, adjust iframe height accordingly.

  • Also, you can pass options for customizing widget via query string:

  • Available query params for AMP

Do not forget to URL-encode parameters.
