Pull request overview
This PR implements Phase B of the @objectql/driver-turso package, adding multi-tenant routing, automated schema migration, and kernel plugin integration capabilities. It builds incrementally on the existing Phase A implementation (v4.2.2, 125 tests) without modifying core driver functionality. The additions enable per-tenant database routing with TTL caching, automated DDL generation via schema diff, and integration with the ObjectStack kernel plugin system.
Changes:
- Multi-tenant router with process-level caching, tenant ID validation, and lifecycle callbacks
- Turso Platform API REST client for database provisioning and token management
- Schema diff engine comparing ObjectQL definitions against live database schema
- RuntimePlugin implementation supporting both single-tenant and multi-tenant modes

Potential race condition in concurrent driver creation. If multiple requests call getDriverForTenant for the same tenant simultaneously before the first request completes, each will see a cache miss and create separate driver instances for the same tenant.
This can lead to:
- Multiple active connections to the same tenant database
- Wasted resources (multiple TursoDriver instances)
- Cache thrashing if requests arrive during the connection phase
Consider implementing a promise-based locking mechanism or using a pattern like "promise deduplication" where concurrent requests for the same tenant wait for the first creation to complete. For example, maintain a Map of in-flight creation promises and have subsequent requests await the same promise.
Example pattern:
const creationPromises = new Map<string, Promise<TursoDriver>>();
// In getDriverForTenant:
let creationPromise = creationPromises.get(tenantId);
if (creationPromise) {
return creationPromise;
}
creationPromise = createNewDriver(tenantId);
creationPromises.set(tenantId, creationPromise);
try {
const driver = await creationPromise;
return driver;
} finally {
creationPromises.delete(tenantId);

SQL injection vulnerability in default value formatting. String default values are concatenated directly into SQL without proper escaping. If a default value contains a single quote (e.g., "O'Brien"), it will break the SQL syntax and potentially allow injection.
The code needs to escape single quotes in string default values before concatenation. Replace single quotes with doubled single quotes (SQLite standard) or use parameterized queries. For example, change line 220 to:
sql += \ DEFAULT '${col.defaultValue.replace(/'/g, "''")}'`;`
This is critical because default values come from ObjectQL object definitions which may be user-provided or sourced from external configuration files.
| sql += ` DEFAULT '${col.defaultValue}'`; | |
| const escapedDefault = col.defaultValue.replace(/'/g, "''"); | |
| sql += ` DEFAULT '${escapedDefault}'`; |

Missing input validation for orgSlug and database name parameters. The orgSlug is directly interpolated into URL paths (lines 121, 139, 153, 169) without validation or encoding. If orgSlug contains special characters like "../" or "%2F", it could lead to path traversal issues or unintended API endpoints being called.
Similarly, database names are interpolated without URL encoding (lines 139, 153). While the Turso API likely has its own validation, following defense-in-depth principles, these should be validated and URL-encoded at the client level.
Consider adding validation for orgSlug in the constructor to ensure it matches expected patterns (alphanumeric, hyphens, underscores only). Also, URL-encode the orgSlug and database name parameters when constructing paths, e.g., encodeURIComponent(this.orgSlug) and encodeURIComponent(name).

The autoMigrate configuration option is defined in the interface (line 40) but is never used in the implementation. The onStart lifecycle method doesn't check or implement automatic migration when this flag is set to true.
If this feature is intended to be implemented in this PR, add the logic to run migrations automatically during onStart when autoMigrate is true. If it's planned for a future PR, consider either removing it from the interface for now or adding a TODO comment explaining the planned implementation.
