For client-side applications
These apps don’t require their own database on a dedicated server to manage user specific data and access it when it’s needed. To access that data, apps make calls to Ecwid API, where this data is stored.
Ecwid API has got you covered on two main aspects of developing client-side applications: private data can be stored securely on Ecwid servers and all the hosting for that data is provided by Ecwid as well. This allows for a secure and fast storage for your application’s needs.
For server-side applications
Sometimes server-side applications need to store user’s data as well as the client-side ones. Usually developers create mySQL or PostgreSQL databases or store data locally on a file system.
Application storage offers an alternative - store data on Ecwid servers and access it using REST API. Why it can be helpful: now there is no need for mySQL databases, your code becomes simpler and you don’t have to worry about storing the private merchant data on your servers.
