d1-drizzle-schema

Generate D1-compatible Drizzle ORM schemas by applying integer modes for BOOLEAN and DATETIME emulation, ensuring always-enforced foreign keys, and tracking the 100 bound-parameter limit to prevent migration errors.

Standard SQLite Drizzle schemas break on D1 because D1 always enforces foreign keys, lacks native BOOLEAN and DATETIME types, and imposes strict bound-parameter limits, causing silent runtime failures without D1-aware schema patterns.

Handle boolean and timestamp columns in a Drizzle D1 schema by defining them as integers using specific modes: `integer({ mode: 'boolean' })` for booleans and `integer({ mode: 'timestamp' })` for dates, ensuring correct type emulation.

Yes, you can define foreign keys and indexes safely for Workers by modeling relationships according to D1's always-enforced foreign key constraints and applying indexing patterns that align with D1 behavior to avoid runtime failures.

Cloudflare D1 enforces a 100 bound-parameter limit per query. D1-aware schema generation accounts for this strict limit by structuring data layer definitions to prevent query failures during runtime operations.

Scaffold a D1 data layer by generating D1-compatible Drizzle schemas with tables, relations, indexes, and type exports from your data model description, alongside migration command guidance and DATABASE_SCHEMA.md documentation.
