cf-ui vs React: What are the differences?
cf-ui: A set of over 50 packages used to build UIs at CloudFlare using projects such as React, Redux, npm, Lerna, and more. While moving to React, we’ve taken our existing Backbone UI framework and rebuilt it from scratch on top of React. This includes over 50 packages that include dozens of components, utilities, test helpers, and more; React: A JavaScript library for building user interfaces. Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.
cf-ui and React belong to "Javascript UI Libraries" category of the tech stack.
cf-ui and React are both open source tools. It seems that React with 132K GitHub stars and 24.5K forks on GitHub has more adoption than cf-ui with 1.29K GitHub stars and 89 GitHub forks.
