Using Codemod to upgrade your React version

Refactoring large codebases can be daunting due to the complexity, expense, and time involved, often deterring engineering teams from undertaking such tasks despite the presence of suboptimal code patterns. Codemod, a Python tool developed by Facebook, offers a solution by partially automating the refactoring process, although human oversight remains necessary. It is particularly useful for making systematic changes to mature codebases and can be easily installed via Python package managers. Codemod can automate tasks like deprecating outdated HTML tags or upgrading React versions with minimal disruption, as demonstrated with the update from React 16.5 to 16.9, which introduced the Suspense component. React-Codemod, an npm package, provides scripts for transitioning React APIs, while jscodeshift offers more advanced capabilities for JavaScript refactoring, allowing developers to handle updates efficiently without compromising the product's integrity. These tools enable teams to incorporate modern updates seamlessly, ensuring that codebases remain current without extensive manual labor.
