📝 Walkthrough

Walkthrough

The pull request migrates the backend from Node.js/Express/tRPC to Bun/Elysia/Eden Treaty, updates CI/CD deployment configurations with Sentry release management, and converts all client-side API integrations from tRPC to Eden Treaty across the mobile and web applications.

Poem

🐰 A Bun-ny's Ode to the Great Framework Shift

From Express to Elysia, we hop so fast,
No more tRPC chains that were built to last—
Eden Treaty flows with types so true,
Sentry watches while we're building anew.
Bun at runtime, swift as morning dew! 🚀

15-30: Sentry release tracking has been removed.

The deployment action no longer includes Sentry-related inputs (sentry_api_auth_token, sentry_api_project, sentry_org) or build arguments. This removes the ability to track releases in Sentry during deployment.

If Sentry release tracking is still needed, consider implementing it elsewhere in the deployment pipeline or documenting why it was removed.

🧹 Nitpick comments (6)
apps/web/src/routes/_authorized-layout/route.tsx (1)

233-234: Remove debug console.log statement.

This console.log appears to be debug code that was left in. The errReason is already captured in the Sentry context on line 239, making this redundant. Remove it to keep the production code clean.

🔎 Proposed fix
-      console.log(errReason);
-
       Sentry.captureException(new Error(error.type), {
apps/api/README.md (1)

191-192: Documentation incomplete: missing example after the note.

Line 191 states that environment values should NOT have quotes, but there's no example showing the correct format. Consider adding a brief example:

🔎 Suggested addition
 **Important:** When using `--env-file`, values should NOT have quotes around them:
+
+```bash
+# Correct
+DATABASE_URL=libsql://example.turso.io
+
+# Incorrect
+DATABASE_URL="libsql://example.turso.io"
+```
apps/web/src/lib/api.ts (1)

5-5: Consider validating the base URL at runtime.

The client initialization doesn't validate that VITE_API_BASE_URL is defined. While build-time checks may catch this, adding a runtime assertion would provide clearer error messages during development.

🔎 Optional improvement
+const baseUrl = import.meta.env.VITE_API_BASE_URL;
+if (!baseUrl) {
+  throw new Error("VITE_API_BASE_URL environment variable is not defined");
+}
+
-export const api = treaty<App>(import.meta.env.VITE_API_BASE_URL, {
+export const api = treaty<App>(baseUrl, {
   fetch: {
     credentials: "include",
   },
   headers: () => ({
     [TRACE_ID_HEADER]: generateTraceId(),
   }),
 });
apps/api/src/index.ts (1)

55-59: Consider returning an error response from the global error handler.

The onError hook captures exceptions to Sentry and logs them, but doesn't return a structured error response. Elysia may return the raw error message to clients. Consider returning a generic error response to avoid leaking internal details.

🔎 Suggested improvement
   .onError(({ error, code }) => {
     Sentry.captureException(error);
 
     logger.error({ error, code }, "Request error");
+
+    return { error: "Internal server error" };
   })
apps/api/src/routers/databases.ts (1)

30-63: Consider adding error handling for the token refresh operation.

The token refresh logic is correct, but if tursoPlatformClient.databases.createToken fails, the error will propagate unhandled. Consider wrapping the external call in a try/catch to return a more specific error response.

🔎 Suggested improvement
      if (userDb?.access_token && isJwtExpired(userDb.access_token)) {
+       try {
          const newToken = await tursoPlatformClient.databases.createToken(
            userDb.db_name,
          );

          await db
            .update(databases)
            .set({ access_token: newToken.jwt })
            .where(eq(databases.id, userDb.id));

          return { ...userDb, access_token: newToken.jwt };
+       } catch (error) {
+         return status(500, { message: "Failed to refresh database token" });
+       }
      }
apps/api/src/routers/migrations.ts (1)

83-91: Consider pagination for the /full endpoint.

Returning all migrations unbounded could become problematic as the migrations table grows over time.

This is likely fine for now if migrations are expected to remain relatively small in number, but consider adding pagination or a limit if this could scale.

Timestamp: 2025-11-30T06:57:48.510Z
Learning: In apps/web/src/lib/db/operations/settings.ts, the settings table is intentionally implemented as a de-facto singleton without schema-level enforcement. Multiple rows can exist due to initialization races, but all operations (SELECT without WHERE, UPDATE without WHERE) treat rows as synchronized and interchangeable. This is a conscious design decision where code clarity could be improved but functional correctness is maintained.

🔇 Additional comments (44)
CLAUDE.md (1)

28-29: LGTM! Documentation accurately reflects the stack migration.

The updated backend description correctly documents the shift from Node.js/Express/tRPC to Bun/Elysia/Eden Treaty.

.gitignore (1)

14-17: LGTM! Appropriate gitignore entries for Bun binaries.

The new entries correctly ignore the server and migrate binaries produced by the Bun build process.

README.md (1)

58-66: LGTM! API documentation correctly updated.

The API section accurately reflects the migration to Bun/Elysia and includes helpful details about logging and hosting infrastructure.

apps/api/fly.toml (1)

8-9: LGTM! Proper use of Fly.io release command for migrations.

The release_command configuration correctly executes migrations before the application starts, following Fly.io best practices.

apps/web/README.md (2)

15-15: LGTM! Documentation correctly reflects Eden Treaty integration.

The README accurately documents the migration from tRPC to Eden Treaty for type-safe API communication.


48-48: LGTM! API architecture description updated correctly.

The architecture section accurately describes the new Elysia/Eden Treaty API integration.

apps/api/src/db/migrate.ts (1)

1-14: Environment variables are properly loaded via Bun's built-in .env loading.

Bun automatically loads .env files, so the removal of dotenv/config from migrate.ts is safe and follows best practices. Environment variables are validated at startup in apps/api/src/utils/config.ts using Zod—if any required variables are missing, the process exits with a clear error message. This validation runs when db/index.ts is imported and when the main app starts in src/index.ts. The drizzle.config.ts file retains dotenv/config for drizzle-kit commands, ensuring migrations work consistently across local development, production deployments, and CI/CD pipelines.

package.json (1)

23-23: The Bun version requirement >=1.3 is appropriate and already permits the current latest stable version (1.3.5). No update is needed.

apps/web/package.json (1)

14-15: LGTM!

The dependency changes correctly reflect the migration from TRPC to Eden Treaty. The @elysiajs/eden package is the appropriate type-safe client for the Elysia backend.

apps/web/src/App.tsx (1)

47-53: LGTM!

The TRPC provider has been cleanly removed. The simplified provider hierarchy with QueryClientProvider directly wrapping the app is correct for the Eden Treaty migration. As per the coding guidelines, the component follows React functional style with hooks and appropriately uses TanStack Query for async state.

apps/api/README.md (1)

7-9: LGTM!

The tech stack documentation accurately reflects the migration to Bun runtime, Elysia framework, and Eden Treaty for type-safe clients.

apps/api/Dockerfile (2)

59-79: LGTM!

The Dockerfile multi-stage build is well-structured. Using debian:12-slim for the final image is appropriate since Bun compiles to native binaries. The external @libsql/linux-x64-gnu module handling is correct, and the drizzle migrations are properly copied for runtime schema management.


1-4: Bun version 1.3.5 is confirmed to be available and compliant.

The Docker Hub registry confirms that Bun 1.3.5 is available across all image variants. The pinned version satisfies the README requirement of >= 1.3, and no availability or stability issues were identified.

apps/mobile/src/app/(search)/decks.tsx (1)

22-22: LGTM!

The import path update from @/utils/trpc to @/utils/api correctly aligns with the Eden Treaty migration. The queryClient usage for cache invalidation remains unchanged and follows the TanStack Query patterns per the coding guidelines.

apps/mobile/src/components/settings/SettingsScreen.tsx (1)

24-24: LGTM!

The import path update aligns with the project-wide migration to Eden Treaty. The queryClient usage for cache invalidation after settings updates is unchanged and correct.

apps/mobile/src/app/(search)/(home)/add-word.tsx (1)

34-34: LGTM!

The import path update is consistent with the Eden Treaty migration. The component continues to use queryClient correctly for cache invalidation after word creation.

apps/mobile/src/app/(search)/_layout.tsx (1)

27-27: LGTM!

The import path update aligns with the Eden Treaty migration. The layout's sync handling with queryClient.invalidateQueries() and Jotai atoms for sync state follows the coding guidelines correctly.

apps/mobile/src/components/flashcards/FlashcardReview.tsx (1)

29-29: LGTM! Import path updated correctly.

The queryClient import source has been properly updated to align with the Eden Treaty migration, with no changes to usage or behavior.

apps/mobile/src/app/(search)/settings.tsx (1)

28-28: LGTM! Import path updated correctly.

The queryClient import source has been properly updated to align with the Eden Treaty migration.

apps/mobile/src/app/_layout.tsx (1)

35-35: LGTM! Import path updated correctly.

The queryClient import has been updated to use the new API utilities module, maintaining the same usage pattern in the QueryClientProvider.

apps/mobile/src/components/decks/CreateDeckForm.tsx (1)

16-16: LGTM! Import path updated correctly.

The queryClient import has been updated to align with the Eden Treaty migration.

apps/mobile/README.md (1)

16-16: LGTM! Documentation updated correctly.

The tech stack documentation accurately reflects the migration from tRPC to Eden Treaty for type-safe API communication.

apps/mobile/src/app/(search)/(home)/edit-word/[id].tsx (1)

35-35: LGTM! Import path updated correctly.

The queryClient import has been updated to use the new API utilities module, with no changes to the invalidateQueries usage.

apps/web/src/lib/api.ts (1)

1-12: LGTM! Eden Treaty client properly configured.

The API client setup correctly:

  • Uses type-safe Eden Treaty with the App type from the API server
  • Includes credentials for authentication cookies
  • Adds trace IDs to all requests for observability
  • Generates fresh trace IDs per request via the headers function
.github/actions/fly-deploy/action.yml (1)

15-17: The workflow that uses this action (.github/workflows/deploy-server.yml) has been properly updated to pass the github_sha input with ${{ github.sha }}. The integration is correct and there are no compatibility issues.

apps/mobile/src/utils/api.ts (1)

8-12: Missing credentials: "include" and trace header compared to web client.

The web client at apps/web/src/lib/api.ts includes fetch: { credentials: "include" } and a trace ID header, but this mobile client only passes a cookie header. While the cookie header handles authentication, verify that Eden Treaty properly sends credentials for cross-origin requests in React Native context. Consider adding a trace ID header for consistent observability across clients.

 export const api = treaty<App>(process.env.EXPO_PUBLIC_API_BASE_URL!, {
+  fetch: {
+    credentials: "include",
+  },
   headers: () => ({
     cookie: authClient.getCookie(),
+    "x-request-id": crypto.randomUUID(),
   }),
 });
apps/mobile/package.json (1)

19-19: LGTM!

The migration from tRPC packages to @elysiajs/eden is clean. The api workspace dependency in devDependencies correctly enables type imports for the treaty client.

apps/mobile/src/lib/db/index.ts (3)

78-82: LGTM!

The Eden Treaty API call pattern with destructured { data, error } and error throwing is consistent with the web client implementation. The error handling within tryCatch preserves the existing Result-based error mapping.


111-115: LGTM!

Token refresh API call correctly migrated to Eden Treaty pattern.


192-196: LGTM!

Migrations API call correctly migrated to Eden Treaty pattern.

.github/workflows/deploy-server.yml (2)

32-42: LGTM!

Sentry release management is properly configured with commit association and sourcemap uploads. Using github.sha as the release identifier aligns with the GITHUB_SHA environment variable used in apps/api/src/index.ts line 8.


28-30: No action needed. The workflow build command is correct for its purpose.

The bun build --sourcemap --outdir dist in the workflow (lines 28-30) is specifically for generating source maps to upload to Sentry (lines 32-42), not for deployment. The actual deployment uses the Dockerfile, which independently compiles the server binary via bun build --compile --outfile server. These are two separate builds serving different purposes: the workflow generates sourcemaps for debugging, while the Dockerfile creates the production binary. No mismatch exists.

Likely an incorrect or invalid review comment.

apps/api/src/index.ts (2)

1-10: LGTM!

Sentry initialization is correctly placed before any other imports, which is critical for proper instrumentation. The release is tied to GITHUB_SHA for traceability to specific deployments.


40-51: LGTM!

The request tracing setup correctly propagates existing x-request-id headers or generates new UUIDs, and uses AsyncLocalStorage via traceContext.enterWith() for request-scoped context.

apps/web/src/lib/db/index.ts (3)

72-76: LGTM!

Eden Treaty API call pattern is consistent with the mobile implementation and correctly integrated with the existing tryCatch error handling.


113-117: LGTM!

Token refresh API call correctly migrated.


186-190: LGTM!

Migrations API call correctly migrated.

apps/api/package.json (2)

21-39: LGTM!

Clean migration from Express/tRPC ecosystem to Elysia with appropriate dependencies. The @sentry/bun package correctly replaces the Node.js-specific Sentry packages for Bun runtime.


10-10: The deployment is specifically configured for Linux x86_64 (debian:12-slim), and the --external @libsql/linux-x64-gnu flag is correctly handling the native module for that platform. The Dockerfile explicitly copies the native module at runtime, and fly.toml contains no multi-platform or ARM64 configuration. No additional platform-specific externals are needed for the current deployment setup.

apps/api/src/middleware.ts (1)

6-32: LGTM!

The Elysia macro pattern for authentication is well-structured. The guard correctly:

  • Mounts better-auth handler for auth routes
  • Returns 401 for unauthenticated requests
  • Returns 403 for non-admin users when admin role is required
  • Enriches trace context and Sentry with user information
  • Passes user/session to downstream handlers

The role="user" simply means "authenticated user required" (any role passes), which aligns with usage in apps/api/src/routers/databases.ts and apps/api/src/routers/migrations.ts.

apps/api/src/routers/databases.ts (1)

9-29: LGTM! Clean migration to Elysia for the GET /user endpoint.

The route correctly uses the betterAuthGuard middleware and route-level authentication. The error handling with status(404, ...) is appropriate for the Elysia framework.

apps/api/src/routers/migrations.ts (3)

8-31: LGTM! Good use of admin-level authentication for migration registration.

The route correctly restricts access to admin users and uses Zod for body validation. The error handling with a 400 status for insert failures is appropriate.


32-48: LGTM! Clean implementation of version retrieval.

Returning { version: 0 } when no migrations exist is a sensible default for new databases.


49-82: LGTM! Migration verification logic is correct.

The as const assertions properly narrow the status type for type-safe client consumption. The logic correctly identifies required migrations and returns appropriate responses.

⚠️ Potential issue | 🟠 Major

Incomplete error handling for non-HTTP and server errors.

The error handling only covers specific HTTP status codes (401/403, 400/422) but doesn't handle:

  • Network errors (no status property)
  • Server errors (5xx status codes)
  • Other client errors (404, 409, etc.)

Users may encounter unhandled errors with no feedback, degrading the UX.

lines 36 to 62, the mutation only handles a few HTTP statuses and ignores
network errors, 5xx server errors, and other status codes; update the
switch/error handling to: detect if error is falsy and return result normally,
if error.status is undefined treat as a network error and show a toast like
"Network error: please check your connection" (include error.message if
present), handle 5xx with a server error toast, handle other/unexpected status
codes with a generic failure toast that includes status and message when
available, ensure you still throw the error after showing a toast and optionally
log full error details to console or telemetry for debugging.

Fix documentation: the environment variable should be VITE_API_BASE_URL, not VITE_API_URL.

The web app README documents VITE_API_URL as a required environment variable, but the code consistently uses VITE_API_BASE_URL across api.ts, auth-client.ts, and router.ts. Update the README to reflect the correct variable name.

The utility imports (TRACE_ID_HEADER and generateTraceId) are correctly exported and the treaty configuration itself is sound.
