Fingerprint your native runtime with @expo/fingerprint
Blog post from Expo
Expo has introduced a new tool called @expo/fingerprint, designed to streamline app development processes in React Native by generating a unique hash that encapsulates a project's native characteristics. This innovation addresses common challenges such as determining whether a pull request includes native code changes, assessing compatibility with production app runtime, and deciding if a development build is necessary. By utilizing the command `npx @expo/fingerprint@latest`, developers can quickly obtain a comprehensive overview of their project's native setup, enabling the detection of native changes through a single succinct hash value. The tool is designed for speed, precision, and customizability, supporting both Expo CLI projects and bare React Native apps. Additionally, it offers API integration for programmatic use, supports diffing to identify changes, and reads a .fingerprintignore file for excluding irrelevant files. Expo is seeking community feedback to refine @expo/fingerprint and plans to integrate it with EAS services, providing a seamless experience for automated decision-making regarding app updates and builds.
