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.
