The newly launched use-stripe-subscription package simplifies the implementation of Stripe billing for frontend developers by providing a set of tools and features, such as the useSubscription() React hook that returns available subscription products and manages subscription sessions, all without exposing the secret key to the frontend. Built by Clerk, the package aims to replace the often in-house developed solutions with a secure and open-source alternative that integrates seamlessly with any authentication and user management system. It leverages Stripe's Customer and Customer Portal Configuration objects to securely authorize actions users can perform on their own, ensuring frontend APIs are self-serve and protected from unauthorized access. The package eliminates the need for webhooks by making just-in-time API requests to Stripe for updated data, although this approach may encounter Stripe's API rate limits, leading to future enhancements involving robust caching solutions.
