D1 Migration

This handles the full Cloudflare D1 migration lifecycle with Drizzle ORM, from generating SQL to recovering from stuck migrations. The workflow emphasizes reading generated SQL before applying it because Drizzle sometimes creates destructive table recreations for simple changes like updating a default value. You get commands for local and remote migrations, diagnosis steps for partially applied migrations that get stuck, and fixes for common D1 gotchas like parameter limits on bulk inserts. Worth using if you've ever had a migration fail halfway through or wondered why your local database works but production breaks.
