![]() ![]() iframe embeds make development easier.In order to display the same review widget with direct embeds, widgets.js needs to retrieve review data from Yelp, construct the markup for the content, and style the markup. widgets.js only needs to construct the iframe and it defers rendering and styling the review widget to the iframe. iframe embeds allow for a simpler widgets.js.Iframe embeds are preferable to direct embeds in these ways: Review widgets are served as Yelp pages within iframes, adhere to the Yelp Styleguide, and show the most up-to-date review. We decided to have widgets.js create the fully styled embedded review widgets within iframes, rather than directly in the containing page. Widgets.js does a bit of magic to create a fully styled embedded review. Once the page loads, widgets.js executes. Dynamically Creating the Fully Styled Embedded Review Widgets.js consists of pure JavaScript with no dependencies on libraries so it can run on any website. All of the functionality of loading in the fully styled embedded content is contained in widgets.js. For our HTML snippet, we included some static links in case the JavaScript couldn’t load. Good candidates for the HTML snippet are static, unstyled, or empty elements such as the script tag.

The embed HTML we provide uses a script tag that loads JavaScript called widgets.js. This lets us keep the content up to date and roll out changes to our embed widget without requiring updates to the HTML snippets. With our embedded content, we took the approach of minimizing the HTML snippets that content creators and business owners embed on the web page, and dynamically loading in a fully styled widget when users view the page the widget is embedded on. Minimizing HTML and Maximizing Functionality Embedded reviews also need to gracefully handle traffic spikes from popular websites. ![]() Embedded reviews need to load fast alongside the content on the embedding page. Performance is a major consideration for the embed widget. To better understand how embedding is being used, and to inform future improvements, we should also record accurate analytics on the widgets to see where reviews are being embedded and which reviews are being embedded. The content should also stay up-to-date with contextual information like the latest rating of the business and the reviewer’s most recent edit of their review. The HTML snippet renders and displays fully styled embedded review widgets which should be responsive, so that it looks good on any website or any device. It should also be consistent so that it doesn’t need to be changed every time the review widget is updated with new contextual information. The HTML snippet is what content creators and business owners copy and paste onto their websites, so it should have the minimal amount of HTML code necessary to achieve an embedded review.
