When TURSO_DATABASE_URL is set, both local dev (objectstack.config.ts) and Vercel serverless (api/[[...route]].ts) use the Turso driver for persistent data. Falls back to MemoryDriver/InMemoryDriver when no Turso env vars are configured. - objectstack.config.ts: environment-aware createDefaultDriver() - api/[[...route]].ts: conditional TursoDriver with connect() lifecycle - package.json: add @objectql/driver-turso workspace dependency - build-vercel.sh: include driver-turso in Vercel build - README.md: document TURSO_* env vars - CHANGELOG.md: add entry for driver switch Co-authored-by: hotlong <50353452+hotlong@users.noreply.github.com> Agent-Logs-Url: https://github.com/objectstack-ai/objectql/sessions/2e9116aa-8592-4683-80d3-7ded73f135c5

Pull request overview

Updates apps/demo to support persistent storage by selecting @objectql/driver-turso when TURSO_DATABASE_URL is set, while keeping an in-memory fallback for zero-config local development and deployments without Turso configuration.

Changes:

Add env-aware driver selection (Turso vs memory) for both local config and Vercel serverless bootstrap.
Ensure Turso driver is built and included as a workspace dependency for the demo app.
Document Turso-related environment variables and update changelog entry.

+        return createTursoDriver({
+            url: tursoUrl,
+            authToken: process.env.TURSO_AUTH_TOKEN,
+            syncUrl,
+            sync: syncUrl
+                ? {
+                    intervalSeconds: Number(process.env.TURSO_SYNC_INTERVAL) || 60,


TURSO_SYNC_INTERVAL parsing uses Number(...) || 60, which forces 0 to become 60. The Turso driver config explicitly allows intervalSeconds = 0 (manual-only), so this prevents disabling periodic sync. Parse with an explicit finite-number check and default only when the env var is missing/invalid, while preserving 0.

apps/demo/objectstack.config.ts

+            start: async () => {
+                // Connect Turso driver if applicable (MemoryDriver.connect() is a no-op)
+                if (typeof (defaultDriver as any).connect === 'function') {
+                    await (defaultDriver as { connect: () => Promise<void> }).connect();
+                }


The start hook uses (defaultDriver as any) and a runtime typeof ...connect check, but both MemoryDriver and TursoDriver expose async connect(). Prefer typing defaultDriver against a shared interface/type and calling await defaultDriver.connect() directly to avoid any and keep this type-safe.

+            sync: syncUrl
+                ? {
+                    intervalSeconds: Number(process.env.TURSO_SYNC_INTERVAL) || 60,
+                    onConnect: true,
+                }
+                : undefined,


TURSO_SYNC_INTERVAL parsing uses Number(...) || 60, which forces 0 to become 60. Turso supports intervalSeconds = 0 (manual-only), so this makes it impossible to disable periodic sync via env var. Use an explicit finite-number check and only default when unset/invalid, preserving 0.

Copilot · 2026-03-21T08:43:43Z

apps/demo/api/[[...route]].ts

+        // DriverPlugin from @objectstack/runtime expects the upstream Driver interface;
+        // TursoDriver implements @objectql/types Driver which is structurally compatible.
+        await withTimeout(kernel.use(new DriverPlugin(tursoDriver as any, 'turso')), PLUGIN_TIMEOUT_MS, 'DriverPlugin-turso');
+        log('TursoDriver registered.');


Passing tursoDriver as any into DriverPlugin removes type safety and can mask a real interface mismatch between @objectql/types Driver and what @objectstack/runtime expects. Prefer adapting the Turso driver to the expected driver type (e.g., via a small wrapper/adapter with the required surface area) or importing and using the exact Driver type from @objectstack/runtime to ensure compatibility at compile time.

+                     TursoDriver)


The architecture diagram now shows TursoDriver unconditionally, but this demo still falls back to the in-memory driver when TURSO_DATABASE_URL is not set. Update the diagram to reflect the conditional driver choice (e.g., “TursoDriver / InMemoryDriver”) to keep the docs consistent with the behavior described above.

…cies for Vercel workspace:* packages bypass pnpm's .pnpm virtual store, so their transitive deps are not discovered by patch-symlinks.cjs Phase 1. Add @libsql/client (^0.17.2) and nanoid (^3.3.11) — runtime deps of @objectql/driver-turso — as explicit devDependencies so they are available in node_modules for Vercel bundling.

Added @libsql/client (^0.17.2) and nanoid (^3.3.11) as explicit devDependencies in apps/demo/package.json. Since @objectql/driver-turso is a workspace:* package, its transitive deps bypass pnpm's .pnpm virtual store and aren't discovered by patch-symlinks.cjs Phase 1. Fixed in d2c37c5.

Fixed in 37016be. The lib-cjs/node.js was missing because Vercel's nft traces ESM paths (lib-esm/) but the compiled @objectql/driver-turso uses CJS require() which resolves to lib-cjs/node.js via conditional exports. Changes:

vercel.json includeFiles — added @libsql scope, libsql, @neon-rs, detect-libc, js-base64, promise-limit, nanoid to force Vercel to bundle both CJS and ESM paths
package.json — added @libsql/client's full transitive dep tree (@libsql/core, @libsql/hrana-client, @libsql/isomorphic-ws, @neon-rs/load, detect-libc, js-base64, libsql, promise-limit) as explicit devDependencies
Also addressed review comments: fixed TURSO_SYNC_INTERVAL parsing (preserves 0), removed as any casts, updated README diagram

@copilot The vercel.json schema validation failed with the following message: functions.api/**/*.ts.includeFiles should NOT be longer than 256 characters

Fixed in 138eccd. Converted includeFiles from a single brace-expanded glob (373 chars) to an array of 12 individual patterns (longest is 54 chars). Vercel's schema validates each array element independently, so this stays well within the 256-character limit.
