At the end of August 2017, ten students set foot in the trivago headquarters in Düsseldorf to be part of the first ever trivago Tech Camp. Two weeks were packed with real-world challenges, guest lectures, Q&A sessions, and tons of other opportunities to learn. In the end, a lot of working software was delivered.
trivago will host a PHPUnit Code Sprint in mid-October to support this crucial part of the PHP ecosystem. Sebastian Bergmann, the creator of PHPUnit, will be there to coordinate the developers’ efforts and to answer questions.
trivago has decided to sponsor Webpack with a monthly contribution of $10,000 ($120,000/year). We hope that this will help to secure the continued innovation of the project.
Our first right-to-left platform was released in 2014. We had developed a solution to generate right-to-left CSS with Sass mixins and variables as we have described in a blog article. We used this approach for nearly 3 years but recently migrated the right-to-left CSS generation from pre-processing to post-processing with RTLCSS. With this article I would like to share the reasons for the migration as well as our experiences and lessons learned.
Running Cucumber scenarios in parallel can be tricky, especially when a custom test runner is used. That’s why we created Cucable - a Maven plugin to split test scenarios into smaller chunks that can be run at the same time.
Tackling hard problems is like going on an adventure. Solving a technical challenge feels like finding a hidden treasure. Want to go treasure hunting with us?

We, Marcos Pacheco and Marcus Tannerfalk, work as Agile Coaches in the Palma office for the hotel search company trivago. This is our experience in working with a development team in daily sprints with the goal of delivering an MVP (minimum viable product)
At trivago we use Jenkins as our main CI tool. However, when our physical setup was not enough we needed to move it to the cloud and implement an automated slave scaling. This is the definite guide with all the steps we took to implement an auto scaling Jenkins platform.
Concepts like separation of concerns, logic decoupling or dependency injection are things we developers have heard more than a couple of times. At trivago, the Android app is developed using the Model View ViewModel (MVVM) architecture, aiming for views as dumb as possible, leaving the decision making to the view models. This leads to an increased test coverage since testing logic in views is something we can’t do that easily.
For our products, like the trivago hotel search, we are using Redis a lot. The use cases vary: Caching, temporary storage of data before moving those into another storage or a typical database for hotel meta data including persistence. The main parts of the hotel search are built with PHP and the Symfony Framework for the frontend (web) and Java for the backend part. In this article, we will focus on the collaboration between our PHP application and Redis. Both are running fine, but it was a long and hard way up to the current situation. This is the story of how we learned to use Redis, including our failures and experience.
