Move src/ → apps/server/ and packages/web/ → apps/web/ to adopt standard monorepo conventions (apps/ for runnable apps, packages/ for reusable libraries). Update all config files, shared package imports, test fixtures, and documentation to reflect new paths. Key fixes: - Update workspace config to ["apps/*", "packages/*"] - Update tsconfig.json rootDir/include for apps/server/ - Add apps/web/** to vitest exclude list - Update drizzle.config.ts schema path - Fix ensure-schema.ts migration path detection (3 levels up in dev, 2 levels up in dist) - Fix tests/integration/cli-server.test.ts import paths - Update packages/shared imports to apps/server/ paths - Update all docs/ files with new paths

# Database Migrations
|
|
|
|
This project uses [drizzle-kit](https://orm.drizzle.team/kit-docs/overview) for database schema management and migrations.
|
|
|
|
## Overview
|
|
|
|
- **Schema definition:** `apps/server/db/schema.ts` (drizzle-orm table definitions)
|
|
- **Migration output:** `drizzle/` directory (SQL files + meta journal)
|
|
- **Config:** `drizzle.config.ts`
|
|
- **Runtime migrator:** `apps/server/db/ensure-schema.ts` (calls `drizzle-orm/better-sqlite3/migrator`)
|
|
|
|
## How It Works
|
|
|
|
On every server startup, `ensureSchema(db)` runs all pending migrations from the `drizzle/` folder. Drizzle tracks applied migrations in a `__drizzle_migrations` table so only new migrations are applied. This is safe to call repeatedly.
|
|
|
|
## Workflow
|
|
|
|
### Making schema changes
|
|
|
|
1. Edit `apps/server/db/schema.ts` with your table/column changes
|
|
2. Generate a migration:
|
|
```bash
|
|
npx drizzle-kit generate
|
|
```
|
|
3. Review the generated SQL in `drizzle/NNNN_*.sql`
|
|
4. Commit the migration file along with your schema change
|
|
|
|
### Applying migrations
|
|
|
|
Migrations are applied automatically on server startup. No manual step needed.
|
|
|
|
For tests, the same `ensureSchema()` function is called on in-memory SQLite databases in `apps/server/db/repositories/drizzle/test-helpers.ts`.
|
|
|
|
### Checking migration status
|
|
|
|
```bash
|
|
# See what drizzle-kit would generate (dry run)
|
|
npx drizzle-kit generate --dry-run
|
|
|
|
# Open drizzle studio to inspect the database
|
|
npx drizzle-kit studio
|
|
```
|
|
|
|
## Rules
|
|
|
|
- **Never hand-write migration SQL.** Always use `drizzle-kit generate` from the schema.
|
|
- **Never use raw CREATE TABLE statements** for schema initialization. The migration system handles this.
|
|
- **Always commit migration files.** They are the source of truth for database evolution.
|
|
- **Migration files are immutable.** Once committed, never edit them. Make a new migration instead.
|
|
- **Test with `npx vitest run`** after generating migrations to verify they work with in-memory databases.
