Extra functions

We go one step further and provide common web/mobile apps functionalities.

StaticBackend’s goal is to provide all the building blocks you need to build your applications. We’re not just stopping at the database.

The extra endpoints implement useful functionalities that web and mobile applications need.

  console.error(res.content);
