Two years ago, Bit announced an upgrade to its React environment, enhancing its capabilities and refining the developer experience based on community feedback. This upgrade includes default support for ESM, out-of-the-box compatibility with React 18, and simplified tooling configurations, aiming to reduce abstractions and improve the control over component templates. The new environment allows developers to customize their setup by directly modifying configuration files and provides a more flexible React Preview API for creating custom rendering environments. Developers can smoothly migrate from previous implementations by creating a new environment and reconfiguring their components, although transitioning from CJS to ESM may present some challenges. The changes intend to empower development teams to tailor their workflows and have greater control over their tooling, ultimately enhancing productivity.
