Drupal is the world’s popular and widely used CMS
framework. Drupal back-end system is very strong and can be used for managing
any type of content like text, categories, media, geospatial, etc.
The term Headless Drupal means, use Drupal as a backend
system and Rest server, so that content operations (read, update, delete) can
be done from another language or tool. Drupal 8 comes with Rest Server included
in its core. In Drupal 7 we can achieve this with a contributed module called
Services or RestWS.
Nowadays people are using many devices like desktops,
laptops, mobiles, tablets to explore the content and in parallel front-end
frameworks are also invented to provide a better user experience while viewing
content among different devices.
Since most people are using smartphones these
days, many businesses want to stay with people always by providing their
services through mobile apps and attract people with some offers and ads.
Using Headless Drupal content-rich back-end system can
be done very quickly and data can be exposed through REST API. The front-end can be
done by using any of the desired front-end frameworks like Angular JS, Backbone, or any other similar framework. We can also use the same REST API for
developing mobile applications.
This way we can build different kinds of applications
like a single page (SPA), responsive, mobile apps, etc. with a single Drupal back-end
system.
