Good performance is critical to delivering a good user experience, and iOS users often have high expectations of their apps. A slow and unresponsive app might make users give up on using your app or, worse, leave a bad rating. In this article, Axel Kee is going to look into five optimization tricks that will make your app feel more responsive.

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.

Climate change may not seem like an issue that should concern web developers, but the truth is that our work does have a carbon footprint, and it’s about time we started to think about that. As web developers, it’s understandable to feel that this is not an issue over which we have any influence, but this isn’t true. Many efforts are afoot to improve the situation on the web. The Green Web Foundation maintains an ever-growing database of web hosts who are either wholly powered by renewable energy or are at least committed to being carbon neutral. So, apart from powering servers with renewable energy, what else can web developers do about climate change?

When creating a multi-step form in which a file is uploaded and manipulated, if the application is running on several servers behind a load balancer, then we need to make sure that the file is available all throughout the execution of the process, for whichever server handles the process at each step. In this article, Leonardo Losoviz will solve this issue by creating a repository accessible to all servers where to upload the files, based on AWS S3.

Animated GIFs are popular on the web for good reason. They provide more engagement than an ordinary image, while remaining more digestible compared to a typical video. However GIFs are a terrible format for storing video and are often huge in size leading to slow page load times and high data usage. With HTML5 video, you can reduce the size of GIF content by up to 98% while still retaining the unique qualities of the GIF format in the browser. Today, Ayo Isaiah will show you how to convert animated GIFs to video files and examine how to properly embed these video files on the web so that they act just like a GIF would.

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.

Everyone knows that if a website is slow, users will abandon it. Many studies demonstrate the connection between website performance and conversion rates. Being an easy-to-use inclusive and versatile piece of software, WordPress comes with a plethora of options that are not necessarily utilized in each and every project. As a result, website performance can suffer. In this article, Denis Žoljom shares his experience and the basics of creating a decoupled WordPress.

Since video files are large, optimizing the video to be as small as possible will lead to faster video delivery, speeding up video start, lowering the number of stalls, and minimizing the effect of the quality of the video delivered. Of course, we need to balance startup speed and stalling with the third metric of quality. In this series of posts on video performance on the web, Doug Sillars takes a closer look at how video is being used today, what we can learn from it, and how to move forward in a way that promotes fast delivery and playback of video content on the web.

Video content on the web increases customer engagement and satisfaction. Pages that load quickly have the same effect. The addition of video to your website will slow down the page rendering time, necessitating a balance between overall page load and video content. In this aticle, Doug Sillars will examine the important metrics to balance performance and video playback on the web, look at how video is being used today, and provide best practices on delivering video on the web.
