End-to-end can be challenging for focus-based interfaces like Smart TV apps that rely on LRUD (Left, Right, Up, Down) navigation. This article shares how the TVJS team overcame the instability in their Cypress test suite by incorporating focus-aware assertions and adapting testing strategies for directional navigation, leading to more reliable and trustworthy automated tests.

Ever since websites started being made essentially from JavaScript, transpiling this code to run in the largest number of different browsers has been an essential step in the build process. From the very beginning, more than ten years ago, the BedrockStreaming web application has relied on Babel for this task. This year we migrated from Babel to its next-gen replacement, SWC. It was not a smooth ride all the way, so let’s see what challenges we’ve had to overcome and if the payoff was worth the effort!

On October 30-31, the Bedrock Web & TV team attended performance.now() 2025 in Amsterdam, one of the few conferences entirely dedicated to web frontend performance. Two intense days of real-world insights, browser deep-dives and discussions about what “fast” truly means in 2025.

Streaming is now everywhere, an indispensable part of our daily lives, used by almost everyone for entertainment, communication, and learning. It appears effortless, almost magical, as high-quality video instantly appears on our screens. But beneath that seamless playback lies a complex and fascinating architecture of web technologies. Have you ever wondered what truly happens behind the frame to bring those pixels to life, adapting to your network, and ensuring a smooth experience right within your browser? Join us as we pull back the curtain and demystify the magic of modern web video playback.

Bedrock était présent au MiXiT 2025, les 29 et 30 avril à Lyon. Voici un petit résumé des conférences qui nous ont le plus marqués.

Le Devoxx est un événement incontournable pour les développeurs et les professionnels de la technologie, qui a eu lieu du 16 avril 2025 au 18 avril 2025 au Palais des Congrès de Paris.

Accessibility is at the heart of our concerns, at Bedrock Streaming we work hard to make our applications accessible to everyone. In this article, I’m going to share with you how my team and I improved our accessibility score of our SmartTV apps by 18% in just a few months! This improvement is even more impressive because on smartTV we have to manage several constraints, including taking into account the specificities of each device (Tizen, WebOS, Hisense, Panasonic, etc.).

One of the core experiences of a Bedrock app for the end user is browsing the catalog. Scrolling vertically through blocks of content, and scrolling horizontally through lists of items. However, TVs do not offer high performance and provide poor user experience during heavy resource actions. We especially noticed that scrolling horizontally in a list was laggy and unpleasant. This article focuses on performance optimization to enhance the horizontal scroll experience on Smart TVs.

Attending the Golab conference in Florence has been a thrilling experience for us as developers. Immersing ourselves in talks by some of the most brilliant minds in the Go community gave us a deeper understanding of advanced concepts, practical libraries, and the future of Go. We’ve summarized the key takeaways from the talks we attended to share some of the valuable lessons and fresh perspectives we gained.

During the UEFA Euro football cup in June and July 2024, M6 broadcasted several matches. Of course, this competition was available, live, on M6+. For every user joining right from the first second and or for all users hearing their neighbors shouting and wanting to re-watch the action, starting a live video stream had to work!
