FileSystem

This document describes the FileSystem library available in the JavaScript environment for app serivices.

Important: innovaphone uses that library for very special purposes. In general apps should not use the file system but store all data and configuration inside the database for several reasons:

Only the database content is included in backups.
Only the database content is included in replication.
The FileSystem library grants access using the user of the app service. So there is isolation between different app services. But there is no isolation between different app instances of one app service.
