Types

type Database

type Database struct {
	// contains filtered or unexported fields
}

Database represents a database connection with migration capabilities.

func New

func New(connection string) (*Database, error)

New creates a new Database instance with the given connection string.

Migrate runs all pending migrations for registered repositories.

func (*Database) RegisterRepository

func (db *Database) RegisterRepository(name string, repository any)

RegisterRepository registers a repository in the database. If repository implements migrator interface, it will migrate when `Migrate` is called.

type Migration

type Migration struct {
	ID   string
	Up   string
	Down string

}

Migration represents a database migration with up and down SQL statements.

func ParseMigrations

func ParseMigrations(fsys fs.FS) ([]Migration, error)

ParseMigrations parses SQL migration files from an fs.FS. Files must have .sql extension and contain -- +migrate Up marker. The -- +migrate Down marker is optional. Migration ID is derived from the filename without extension. Migrations are returned sorted lexicographically by filename.
