react-modernization

react-modernization is an agent skill from the wshobson/agents collection for upgrading React applications to current versions and moving them to modern patterns. It covers the version upgrade path, from React 16 to 17 and then 18, with the breaking changes that matter at each step, and the migration of class components to function components with hooks. It also covers adopting concurrent React features such as Suspense and transitions, which let an interface keep responding while slower work is in progress, and applying codemods, which are scripts that rewrite code automatically for a known change. The skill covers modernizing state management patterns and updating a project to TypeScript, along with improving performance with the features available in React 18 and later. It applies when upgrading React applications to the latest versions, migrating class components to hooks, adopting concurrent features, applying codemods to refactor at scale, modernizing state management, adding TypeScript, and improving performance with newer React features. Upgrades of large applications are staged so that each step can be tested, and the skill's version path is designed for that kind of gradual move. The agent performs and explains the changes, and the team checks the result against its test suite and a manual review of key screens. The skill is installed with the skills CLI from the wshobson/agents repository. Its skills.sh page showed about 12.4K installs and passing results from three security audits at the time of the scan.…
