Swap direct access to the DB on the API server with an data abstraction layer. Implement each API type converter separately and revert changes to the auto-generated server implementation types. Add error return to DAL methods. Implement `Transactions`. Add tools.go with oapi-codegen and mockgen. https://www.jvt.me/posts/2022/06/15/go-tools-dependency-management/ Update go packages. Issues #5, #12
