prisma-driver-adapter-implementation

The Prisma driver adapter interface defines a contract mapping database operations to Prisma's driver-adapter-utils, specifying how to execute queries and manage connections. It requires implementing the adapter factory, SqlDriverAdapter, and Transaction interfaces to ensure consistent integration patterns across databases.

You handle transaction lifecycles in a Prisma driver adapter by implementing BEGIN, SAVEPOINT, commit, and rollback semantics within the Transaction interface. This approach manages nested transactions correctly and maintains consistent state boundaries across diverse data sources.

Yes, the guide covers error handling strategies by mapping common database errors to Prisma's MappedError type. This ensures exceptions from new data sources are translated into consistent Prisma ORM errors, maintaining reliable error handling across adapter implementations.

The best way to test a custom Prisma driver adapter is to follow the codified testing strategies that validate correct implementation of SqlDriverAdapter and Transaction interfaces. This ensures proper query execution patterns, transaction lifecycle handling, and error mapping for your specific data source.

Yes, you can use TypeScript to build a driver adapter for Prisma v7, as this guide targets TypeScript engineers. It provides typed interface definitions for the SqlDriverAdapter and Transaction contracts needed to extend Prisma ORM with new database drivers.
