Continuous integration (CI) and continuous delivery (CD) pipelines are essential automated processes that enhance the efficiency and reliability of software delivery for React Native developers, with popular options including EAS Workflows, Microsoft App Center (MAC), GitHub Actions, CodeMagic, Bitrise, and Jenkins. EAS Workflows is praised for its simplicity and efficiency in handling development and release processes for React Native and Expo projects, although its free tier is limited during peak hours. Microsoft App Center supports multiple platforms and offers a generous free tier, but lacks support for Expo apps and local infrastructure. GitHub Actions integrates seamlessly with GitHub repositories, providing more control and automated code quality checks, but may be complex for beginners. CodeMagic offers rapid build times and a pay-as-you-go model, though it lacks a self-hosted option. Bitrise is known for its rapid build times and also operates on a pay-as-you-go model but does not offer self-hosting. Jenkins is favored by enterprises for its self-hosted nature, ensuring maximum privacy, though it requires maintenance of local infrastructure. These platforms are crucial for automating build, test, and deployment processes, reducing the manual workload for developers and improving overall project management efficiency.
