server_store is a configuration item that controls which store this TiddlyWeb instance uses. The setting is a two item list.

The first element of the list is a string representing the name of a module which implements the StorageInterface. The module is first looked up in the tiddlyweb.stores package space and if not found there, sys.path is followed.

The second element of the list is a dict containing configuration needed by the store, for example paths or database names. The dict may be empty. It is also possible to use other, arbitrary, configuration elements.

The default setting for server_store is:
        'server_store': ['text', {'store_root': 'store'}],
