Storage

Unfortunately Tinydb only support JSONStorage and MemoryStorage storage. because this, I add some popular file types like storages.YAMLStorage.

...
app.config["TINYDB_DATABASE_STORAGE"] = YAMLStorage
db = TinyDB(app)
...

of cource you can use your custom text-file storage method with storages.Storage class:

from flask_tinydb.storages import Storage

class MyStorageMethod(Storage):
    def read(self):
        # do_something

    def write(self):
        # do_something

app.config["TINYDB_DATABASE_STORAGE"] = MyStorageMethod
db = TinyDB(app)
...
