Migrations #118

Open quangv opened 7 years ago

In the github description it says ydn-db supports version migration. What is that? Is that converting from one database schema to another? (up/down)

I couldn't find any documentation on migrations.

version migration is implicit. ydn-db grantee that indexedDB has schema as specify during initialisation, otherwise, it will fail.
