Build a universal Vue component library with Vue Demi

Vue Demi, created by Anthony Fu, is a utility designed to simplify the development of universal Vue libraries that are compatible with both Vue 2 and Vue 3, eliminating the need for separate codebases for each version. This tool addresses the challenges faced by developers who previously had to maintain multiple branches for supporting different Vue versions, which increased workload due to duplicated feature implementations and bug fixes. Vue Demi introduces additional APIs to aid in distinguishing between Vue versions and allows the execution of version-specific logic, streamlining the development process. It supports standard Vue APIs while offering the convenience of automatic plugin installation for the Composition API in Vue 2. The article also provides a practical guide on using Vue Demi to create a Vue component library integrated with the Paystack payment gateway, showcasing how to handle props, load scripts, and render components for both Vue 2 and Vue 3 environments.
