Added SkipTables Option

[nlaurie]

In my effort to properly convert dexie-encrypted to work with more complex scenarios, I found the need to completely exclude tables from the import export process. Mainly the encryption metadata.

So I added the options into the project both import and export, to simply skip the requested list of tables in all operations.

I feel this is a good addition to round out the options for controlling the backups.

It's backwards compatible and does nothing if not specified.

Would the filter option not be enough to achieve the same as the proposed skipTables option? Or would it still fail with dexie-encrypted if so?

I started with the filter , it mostly worked but ended up colliding with the clearTablesBeforeImport.

When importing into a database set up with encryption. you don't want to loose you metadata nor do you want to import/export it. so I set skipTables: ['_encryptionSettings']. This way the backup is encryption Free and can be easily imported into a new DB possibly with different encryption params and it will reimport all the data perfectly.

Also Its important especially when one is changing encryption strategy between backups.
