About Gatsby

Gatsby is react based open source framework to create static websites and static web-apps. It is suitable if we are building portfolio sites or blogs or company home pages.

Why Gatsby ?

1. It will build static sites that are Progressive Web Apps .
2. It will follow the latest Web standards.
3. Eco system.
4. Gatsby sites are optimised and highly performant.
5. It will allow us to work with ReactJs, Webpack, GraphQL, ES6+, Js, Css and CSS-in-JS.

I would like to add one more point i.e Building static sites with react is not easy. Because if we take create-react-app as an example it will focus more on Single Page Apps but for Routing, Seo, Performance and Optimisation we need to do lot of configuration which gatsby provide as default in starter's.
