While our company and our application were constantly growing, we often ran into some consistency issues between code and design. Because we didn’t have a design/frontend system and development guidelines to follow, our UI became cluttered and unsustainable.
At trivago we rely heavily on the ELK stack for our log processing. We stream our webserver access logs, error logs, performance benchmarks and all kind of diagnostic data into Kafka and process it from there into Elasticsearch using Logstash.
When using webpack to build your assets, it’s only a matter of time until you wish for targeted builds. Whether it’s the output of the library you’re working on (CJS, UMD, AMD, Var, etc.), or the specific feature set (IE8 support, no IE8 support). parallel-webpack can run those builds in parallel.
One of our core values at trivago is fanatic learning. Twice a year, the trivago software developers gather to have a 2 day internal hackathon. This December saw another round of ambitious creativity, relaxed atmosphere, and good food.

The advances and growth of our Selenium based automated testing infrastructure generated an unexpected number of test results to evaluate. We had to rethink our reporting systems. Combining the power of Selenium with Kibana’s graphing and filtering features totally changed our way of working.
Caching data is an essential part in many high-load scenarios. A local 1st-level cache can augment a shared 2nd-level cache like Redis and Memcached to further boost performance. An in-process cache involves no network overhead, so the cache speed is only limited by local resources like CPU, memory transfer speed and locking.
Last weekend, the Python Hackathon Düsseldorf took place at trivago’s office. Although we were only five people we had a lot of fun. I took the chance to brush up my Python skills a little bit. Also I wanted to scratch an itch that was bugging me for a long time: our housekeeping book.
You know those bugs, like, those. Where the application state dances around you like a crazed Polynesian fire dancer. Where changing the sorting order of a search in London reverts the result list back to Paris… Seriously? Unfortunately, a lot of us are specialists in dealing with this kind of bug.
