What Is GatsbyJS#
GatsbyJS is a modern static site generator for React.
It uses a stack of cutting-edge technologies:
Combining these technologies together, GatsbyJS allows developers to develop their websites with modern best practices and tools:
Code splitting, responsive images, etc
One-directional data flow
ES6 + ES7 automatically transpiled
GatsbyJS sets up a project using the latest technologies, pulling data from almost any source, and generating a static site. It can be done either by whipping together a couple of GatsbyJS plugins, or by using a starter project with all its default configuration.
That is how it is developer friendly. It has a lot of benefits practically, too. Static sites mean you do not need to worry about complex server setup, maintenance, and scaling. Instead you can put GatsbyJS components into a CDN, making the site available as quickly as possible to the users, wherever they are.
