Using WordPress as a Back-end for Your Web API
One other approach QAT Global takes to using WordPress to create PWAs is to use the platform as a back-end for the project. WordPress already provides the necessary tools to create custom fields, post types, and store relevant information. WordPress can be used to process all of the data your app requires and another front-end solution can be selected to create a custom mobile web app experience.
QAT Global’s approach of separating the applications back-end framework from the front-end client enables us to create scalable apps that give you maximum flexibility during development. Also, building an MVP becomes much simpler.
