In the world of APIs, GraphQL has lately overshadowed REST due to its ability to query and retrieve all required data in a single request. Using a component-based API makes most sense when the website is itself built using components, i.e. when the webpage is iteratively composed of components wrapping other components until, at the very top, we obtain a single component that represents the page. In this article, Leonardo Losoviz will describe a different type of API, based around components, which takes a step further the amount of data it can fetch from a single request.

The aim of Feature Policy is for us, as web developers, to be able to state our usage of a web platform feature, explicitly to the browser. By doing so, we make an agreement about our use, or non-use of this particular feature. Based on this the browser can act to block certain features, or report back to us that a feature it did not expect to see is being used. In this article, Rachel Andrew will show you how Feature Policy can help protect your site from third parties using APIs that have security and privacy implications, and also from your own team adding outdated APIs or poorly optimized images.

The Server Timing header provides a discrete and convenient way to communicate backend server performance timings to developer tools in the browser. Adding timing information to your application enables you to monitor back-end and front-end performance all in one place. Over the years developer tools have been improved to help us troubleshoot these sorts of performance issues in the front end of our applications. Browsers now even have performance audits built right in. This can help track down front end issues, but these audits can show up another source of slowness that we can’t fix in the browser.

The Beacon API is a lightweight and efficient way to log information from a web page back to a server. It is used for sending small amounts of data to a server without waiting for a response. Think of it like a postcard sent home when on vacation. You put a small amount of data on it, put it in the mailbox, and you don’t expect a response. In this article, Drew McLellan will help you find out how that can be used and what makes it so different from traditional Ajax techniques.

Whenever we design a web application utilizing real-time data, we need to consider how we are going to deliver our data from the server to the client. The default answer usually is “WebSockets.” But is there a better way? Let’s compare three different methods: Long polling, WebSockets, and Server-Sent Events; to understand their real-world limitations. The answer might surprise you.

GraphQL’s features are not a revolution, but what makes GraphQL powerful is that the level of polish, integration, and ease-of-use make it more than the sum of its parts. Many of the things GraphQL accomplishes can, with effort and discipline, be achieved using REST or RPC, but GraphQL brings state of the art APIs to the enormous number of projects that may not have the time, resources or tools to do this themselves. In this article, Eric Baer focuses almost entirely on why GraphQL exists and the problems it solves.

Manually clicking through different browsers as they run your development code, either locally or remotely, is a quick way to validate that code. However, it’s not a solution for testing the full breadth of your site’s code base on the assortment of browsers and device types available to your customers. That’s where automated testing really comes into its own. In this article, Jason McConnell provides an overview of the concepts, technologies and coding techniques involved with running test scripts against browsers automatically using WebDriverJS on Windows 10 and Microsoft Edge.
