React Native developers can now leverage New Relic's new open beta React Native Mobile agent to enhance the performance and reliability of their applications through comprehensive monitoring capabilities. Announced at FutureStack 19 in New York City, this agent extends New Relic's platform to support React Native, offering features like JavaScript error tracking, native crash monitoring, custom events, mobile breadcrumbs, and session management. While it doesn't currently monitor HTTP errors or requests, it provides a unique perspective from end-user interactions to infrastructure performance. This advancement allows hybrid mobile app developers to gain actionable insights into their app's performance, even on devices with size constraints such as smartwatches. The new agent is designed to capture offline crashes and ensure session continuity, making it suitable for various user activities. New Relic encourages developers to integrate the agent into their pre-production applications and share feedback, while also clarifying that the views expressed in the blog are those of the author and not necessarily reflective of New Relic's official stance.
