DB Migrations Guide
There are some important considerations to make when adding a feature with a db migration.
DB Migrations will require publishing a new API version as the migrations also need to be applied there.
The AQL Schema file will likely need to be updated to match any table changes.
You must place your migration file in the
loot-core/migrations
folder, with a strict naming convention.The naming convention is as follows:
TIMESTAMP_name.sql
. for example.1694438752000_add_goal_targets.sql
It is strongly discouraged to try to remove columns and tables. This makes reverting changes impossible and introduces unnecessary risk when we can simply stop using them in code.
You should be very deliberate with your migration. When adding a feature, try to think about future scenarios and options that may be desired later, so we can minimize the number of migrations.
