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.</description><pubDate>Mon, 30 Jan 2017 00:00:00 GMT</pubDate></item><item><title>Learn Redis the hard way (in production)</title><link>https://tech.trivago.com/post/learn-redis-the-hard-way/</link><guid isPermaLink="true">https://tech.trivago.com/post/learn-redis-the-hard-way/</guid><description>For our products, like the trivago [hotel search](https://www.trivago.com/), we are using [Redis](https://redis.io/) 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.</description><pubDate>Wed, 25 Jan 2017 00:00:00 GMT</pubDate></item><item><title>Code Review: Best Practices and Common Pitfalls</title><link>https://tech.trivago.com/post/code-review-best-practices-and-common-pitfalls/</link><guid isPermaLink="true">https://tech.trivago.com/post/code-review-best-practices-and-common-pitfalls/</guid><description>At trivago we have been using code reviews as a part of our process for a good while now.
