How to build a blog with Cosmic JS and React

Build a Cosmic JS React application by creating a new Cosmic JS App and cloning a repository.


A CMS API gives more power to content creators and developers to build their type of front end web applications. React will continue to receive lots of attention in 2018 as a top Javascript framework. Cosmic JS gives front end developers more time to build client applications and spend less time setting up API’s or Databases. A MongoDB instance would be one more part to what is a simple process. There is no need to update a static file, log into a server. The Cosmic JS content editor powers your application.

Cosmic JS provides a platform that lets developers focus on the code, and design. This means more time pushing code and less time thinking.
