Upgrade Helper is a web tool that assists React Native developers in upgrading their applications between versions.
The tool addresses the challenge of managing breaking changes and configuration updates when moving to a new React Native version. It works by presenting a detailed diff of all files that change between two specified versions, allowing developers to understand exactly what modifications are needed in their codebase. Rather than manually tracking changes across releases, developers can view a side-by-side comparison of the old and new versions and selectively apply relevant changes to their own projects.
Developers upgrading React Native applications should use this tool when moving between versions to gain visibility into what has changed in the framework's template and dependencies. It is particularly valuable for projects that have customized their native configuration files or dependencies, as it helps identify which changes are essential versus which are specific to the default template. The tool is most useful when combined with the official React Native upgrade documentation, as it provides the granular file-level details that complement higher-level migration guides.
The project maintains active engagement with pull requests and issues, indicating ongoing responsiveness to community feedback and bug reports. Development activity shows consistent attention to keeping the tool functional as React Native releases new versions, with updates appearing regularly to support the latest framework releases. The codebase receives contributions that address both tool improvements and updates to the underlying diff data that powers the version comparisons.
