With a 70% increase in internet usage, and digital teams adopting cloud-native technologies at a rapid rate, the importance of measuring customer experience on digital properties is not just a technical problem, but a business imperative. Frontend developers and SREs use Real User Monitoring (RUM) to understand critical components of their end-user experience, like how quickly users see content, when a page becomes interactive, and a page's visual stability.
Three seconds is all it takes before your customer decides to leave. Would you imagine that! The audacity of some people! But, can you really blame them? We live in a fast-paced world. Wasting people’s time is worse than wasting their money. Developers are striving to provide value in as short of time as possible. Just as I am now writing this tutorial. I’m adamant about not wasting your time but providing you with concrete info for you to learn something new.
Since its release in 2013, React.js has become one of the most popular solutions for building dynamic, highly interactive web app frontends. React’s declarative nature and component-based architecture make it easier to build and maintain single-page applications.
As the world increasingly works, buys, and communicates through native mobile apps. In 2020 there were 218 billion new app installs globally, 13.4 billion from the US alone. The challenge, while iOS and Android applications make up significant portions of user traffic and business, engineering teams and monitoring tools are split between mobile app and backend developers; this creates siloed visibility on how changes to the app or backend components impact each other, and end user experience.
Unsurprisingly, application crashes due to fatal errors can be a major pain point for iOS users. Recent research shows that roughly 20 percent of mobile application uninstalls were due to crashes or other code errors. As a developer, it’s paramount to manage this potential churn by capturing comprehensive crash data in order to track, triage, and debug recurring issues in your iOS apps.
