Imagine you go to your hotel for check-in and they say that your dog is not allowed even though the website clearly states that it is! trivago gets information about millions of accommodations from hundreds of partners and they keep on updating. There are many differences not just in the data format, but also in the data itself. There can be many discrepancies in the information and consolidating them can be a very complex process.
We recently hosted a Q&A on our trivago tech Twitter and Life at trivago Instagram page, where we gave our followers the opportunity to ask our developers anything. Even though we tried to answer all of them on the day, we decided to compile some of the most recurring questions and their answers for you below! Getting a tech job at trivago Do you offer any opportunities for React developers? We don’t think in frameworks but in projects.
trivago open sourced a Prettier plugin for the Twig template language. It is available under the Apache 2.0 license, and you can access it on trivago’s Github space. The trivago core product runs on our own frontend framework Melody. Melody uses a Twig-inspired template language because when it was introduced, it had to be interoperable with our existing codebase, which was based on the Symfony PHP framework with Twig as the default template language.
To the outside, trivago appears to be one single software product providing our popular hotel meta search. Behind the scenes, however, it is home to dozens of projects and tools to support it. Teams are encouraged to choose the programming languages and frameworks that will get the job done best. Only few restrictions are placed on the teams in these decisions, primarily long-term maintainability. As a result, trivago has a largely polyglot code base that fosters creativity and diverse thinking.
A quick recap At the end of last year, to celebrate our continued sponsorship of the Open Source community, we hosted a small conference with special guests at our Düsseldorf campus. We initially hoped to welcome Tobias Koppers and Sean Larkin from Webpack, plus some internal speakers. What we didn’t expect was the huge amount of fantastic speakers who wanted to present their projects to the community. In the end, Sean unfortunately couldn’t make it but we did have a chance to welcome Marvin Hagemeister, Juan Picado, Norbert de Langen and Pia Mancini as speakers, plus our own amazing talents.

At trivago, we generate a huge amount of logs and we have our own custom setup for shipping logs using mostly Protocol Buffers. Eventually we end up with some fields in Elasticsearch (ES) that contain partial (or full) URLs. For instance, in our specific case we store the query component of the URL in a field called query and the path component in a field named url_path. Sample values for these fields could be:
A New Dawn, IxDA20 is one of the biggest events dedicated to design and brings together some of the brightest talent in the world from design to psychology to business. At trivago we live diversity. We have 55 localised platforms and internally you can find talents from around 90 different nationalities all working towards providing a better experience to our customers. We are constantly evolving as we face organisational, societal and industrial challenges.
FOSDEM in Brussels is one of our favorite conferences each year as it fully reflects our love for Free and Open Source software. We strongly believe in sharing knowledge not only internally, but also with the tech community around the world. This is one of the reasons why we support Open Source software through development and sponsorship. For example, we are the second biggest supporter on Open Collective and we have a ton of our own Open Source projects too.
