Engineering of High Performance Web Apps
Do you want to start testing applications with WebSocket and Spock, but you’re afraid of running an unstable test? You know what the cinematic Spock says, “Insufficient facts always invite danger”!
Get your facts straight and learn how to avoid common mistakes with our step-by-step guide to WebSocket testing.
We have successfully adopted the Gerrit workflow for pre-commit code review in Evojam. We believe that this a foundation of high quality of our solutions. After two years we have worked out a complete approach for the pre-commit review with Gerrit, branching model and application provisioning. Now I have realized the there is no definite cookbook for the newcomers. This led me to the idea that it may be worth to share this approach with the community. This is not totally unique but may save a newcomer a bit of time.
Performance is a complicated beast. Each step in the problem solving chain of performance issues - identification, diagnosis, rectification and verification, pose unique challenges. This post will deal with themes from the first two steps, and is aimed at teams who are already conducting some form of performance testing.
At Evojam we always seize opportunities for R&D. So when a former client asked us for cooperation on an existing project, which involved a 1 billion member social network, we jumped at the opportunity. We joined the team and did our best to fix bugs and solve data consistency, performance and reliability issues. Additionally, we presented a more effective approach to the application’s architecture. This article briefly covers our journey through the 1 billion member social network.
Google’s Angular and Facebook’s React are now most popular tools for building browser (and not only) applications. Both are great solutions. While Angular2 is still in beta it has been already tested by few Google developer teams – AdWords, GreenTea and Fiber. List of applications built with React is really long and you can find there names like Instagram, Netflix, PayPal and many more.Brutal war is coming.
My simple and practical Intro to Monads in JS, where I covered basics of Identity and Maybe monads, seemed to be helpful for a lot of folks, so I’ve decide to continue the topic. Now it’s time for Either – a tool for fast-failing, synchronous computation chains. A tool that may increase readability and quality of code while reducing error proneness. The best part is that we can still ignore the category theory!
