Examine Expo XDE, an open-source and free suite of development tools built on the React Native framework. Expo XDE aims to streamline and simplify the mobile app development process, from project initiation and working with device APIs to app publishing and updates. This comprehensive toolkit includes a graphical integrated development environment (IDE), a command-line interface (CLI), and an extensive library of pre-built functional components that cater to various popular mobile use cases. These components encompass features like push notifications, device functionalities such as the camera and maps, biometric handling, and more. It's worth noting that Expo was incubated as part of Y Combinator's startup accelerator program, specifically the class of summer 2016.
