Expo Development Client

The `expo-dev-client` package is a fundamental component of the Expo ecosystem, enabling developers to create custom development builds of their React Native applications. Unlike the generic Expo Go app, development builds include your project's specific native code, allowing for the use of custom native modules (third-party native libraries or your own native code) and advanced native configurations without ejecting to a bare React Native workflow. It provides a development environment that closely mirrors production while retaining fast iteration speeds for JavaScript changes. The current stable version is 55.0.28, aligning with Expo SDK 55. Expo SDKs are typically released three times a year, with each release targeting a specific React Native version. Key differentiators include improved debugging tools, a configurable launcher UI for switching between development servers, and seamless integration with EAS Build for cloud-based native builds.
