Hyperdrive API and drivers

Start with README.md and configuration.md. Fetch the selected guide before writing connection or query code; use its current supported package version and compatibility settings.

Driver and binding routes

Task	Official documentation
PostgreSQL with node-postgres (pg), including binding connection string and parameterized queries	node-postgres
PostgreSQL with tagged-template queries and Postgres.js driver options	Postgres.js
MySQL with binding connection properties and Worker-specific driver options	mysql2
Check database features, prepared statements, and library compatibility	Supported databases and features
Generate binding and runtime TypeScript types	Workers TypeScript

Keep an existing supported driver when it fits the application. Choose by database engine and library integration needs; do not infer cache behavior from a driver's prepared-statement setting. Fetch query caching for cache eligibility and freshness controls.

ORMs and query builders

Task	Official documentation
Use Drizzle with PostgreSQL	PostgreSQL Drizzle guide
Use Drizzle with MySQL	MySQL Drizzle guide
Use Prisma with PostgreSQL	Prisma guide
Assess another query builder, including Kysely	Postgres.js integration notes and database compatibility, then the library's current dialect documentation

An ORM still uses a database driver and inherits its Worker connection constraints. Keep clients scoped to the invocation using connection lifecycle. When a library owns SQL for authentication or other fresh reads, pass a client using a cache-disabled configuration as described in query caching.
