feat: auto-detect embedding provider from backend .env

[doublefx]

Base Branch

• This PR targets the develop branch (required for all feature/fix PRs)

Description

Automatically detects the embedding provider configuration from the backend .env file and applies it to the frontend settings. This eliminates the need for users to manually configure embedding settings in the UI when they've already set them up in the backend.

The feature reads GRAPHITI_EMBEDDER_PROVIDER and related environment variables from the backend, then populates the frontend memory settings accordingly.

Code Review Issues Addressed ✅

All issues from code review have been resolved in commit dc6fad8:

Issue #1: Provider Type Mismatch

Fixed in: settings.ts:322

Added 'openrouter' to BackendEmbeddingProvider type to match GraphitiEmbeddingProvider:

export type BackendEmbeddingProvider = 'openai' | 'voyage' | 'google' | 'azure_openai' | 'ollama' | 'openrouter';

Issue #2: Complex Switch Statement

Fixed in: settings-handlers.ts:534-547

Simplified mapEmbeddingProvider function with array-based validation:

Before:

switch (envValue.toLowerCase().trim()) {
  case 'openai': return 'openai';
  case 'voyage': return 'voyage';
  // ... many more cases
}

After:

const mapEmbeddingProvider = (envValue: string | undefined): BackendEmbeddingProvider => {
  if (!envValue) return 'openai';
  const normalized = envValue.toLowerCase().trim() as BackendEmbeddingProvider;
  const validProviders: BackendEmbeddingProvider[] = ['openai', 'voyage', 'google', 'azure_openai', 'ollama', 'openrouter'];
  return validProviders.includes(normalized) ? normalized : 'openai';
};

Issue #3: Missing Error Logging

Fixed in: settings-handlers.ts:593

Added error logging in catch block:

} catch (error) {
  console.error('[Settings] Failed to get backend env embedding config:', error);
  return { success: false, error: 'Failed to check backend embedding config' };
}

Issue #4: Boolean Assignment Simplification

Fixed in: MemoryStep.tsx:107

Replaced ternary operator with !! operator:

Before:

setKuzuAvailable(infraResult?.success && infraResult?.data?.memory?.kuzuInstalled ? true : false);

After:

setKuzuAvailable(!!(infraResult?.success && infraResult?.data?.memory?.kuzuInstalled));

Issue #5: Missing 'openrouter' in UI

Fixed in: MemoryStep.tsx:44

Added OpenRouter to EMBEDDING_PROVIDERS array:

{ id: 'openrouter', name: 'OpenRouter', description: 'Multi-provider API', requiresApiKey: true },

Issue #6: Missing Provider Validation

Fixed in: MemoryStep.tsx:114-115

Added validation before applying detected provider:

const detectedProvider = envConfigResult.data.embeddingProvider;
// Validate that the detected provider is supported
const isValidProvider = EMBEDDING_PROVIDERS.some(p => p.id === detectedProvider);
if (detectedProvider && isValidProvider) {
  setConfig(prev => ({
    ...prev,
    embeddingProvider: detectedProvider
  }));
}

---

Note: Issue about using dotenv library for parsing is deferred for future consideration, as the current implementation works correctly and adding the library would introduce an additional dependency.

122-124: Add error logging to catch block.

The catch block silently swallows errors from the parallel initialization checks. While the fallback behavior (setting kuzuAvailable to false) is acceptable, logging helps with debugging if the backend env config fetch or infrastructure check fails.

🔎 Suggested fix

       } catch (error) {
+        console.error('[MemoryStep] Failed to initialize memory config:', error);
         setKuzuAvailable(false);
       } finally {

apps/frontend/src/shared/types/ipc.ts (1)

62-62: LGTM! Type definitions are consistent.

The import and API signature for getBackendEnvEmbeddingConfig are correctly typed and aligned with the new BackendEnvEmbeddingConfig type defined in settings.ts.

Also applies to: 591-592

apps/frontend/src/shared/types/settings.ts (1)

320-331: LGTM! Type definitions are complete.

The BackendEmbeddingProvider type now includes all supported providers including 'openrouter', and the BackendEnvEmbeddingConfig interface is well-documented and appropriately structured.

apps/frontend/src/shared/constants/ipc.ts (1)

409-410: LGTM! IPC channel constant follows conventions.

The new BACKEND_ENV_GET_EMBEDDING_CONFIG channel is properly defined and documented.

apps/frontend/src/renderer/components/onboarding/MemoryStep.tsx (1)

96-121: LGTM! Parallel initialization with proper validation.

The parallel execution of infrastructure check and backend env config fetch is efficient, and the provider validation against EMBEDDING_PROVIDERS ensures only supported providers are applied. The use of !! for boolean conversion is correct.

apps/frontend/src/main/ipc-handlers/settings-handlers.ts (2)

538-548: LGTM! Clean provider mapping implementation.

The simplified array-based validation with normalization is much more maintainable than the previous switch statement approach. Defaulting to 'openai' aligns with the backend .env.example documentation.

---

550-600: LGTM! Robust error handling with proper defaults.

The handler correctly:

• Returns defaults when source path or .env is unavailable
• Logs errors with console.error for debugging
• Provides graceful fallback to 'openai' provider
• Includes sourcePath and envExists metadata for UI display

44-44: OpenRouter provider entry looks good.

The OpenRouter provider is correctly added to EMBEDDING_PROVIDERS with requiresApiKey: true. The hardcoded strings for name and description are consistent with the existing providers in this array; converting all providers to i18n keys should be done in a separate refactor for consistency.

---

125-127: Add error logging in catch block.

The catch block silently swallows errors from the Promise.all call. While the fallback behavior is acceptable, logging the error aids debugging when either API call fails.

🔎 Proposed fix

-      } catch {
+      } catch (error) {
+        console.error('[MemoryStep] Failed to initialize memory config:', error);
         setKuzuAvailable(false);

52-53: LGTM!

The openrouterApiKey field is correctly added to the MemoryConfig interface, following the existing pattern for other provider API keys.

---

79-92: LGTM!

The state initialization is well-structured:

• Default embeddingProvider set to 'openai' with a clear comment explaining it will be updated from .env on mount.
• openrouterApiKey correctly initialized from settings.globalOpenRouterApiKey following the same pattern as other API keys.

---

149-150: LGTM!

The OpenRouter API key validation is correctly added following the same pattern as other providers.

---

178-180: LGTM!

The OpenRouter API key is correctly persisted to settings with the same pattern used for other global API keys.

---

198-200: LGTM!

The local store update correctly includes globalOpenRouterApiKey, keeping it in sync with the saved settings.

Response to i18n Suggestion

I agree with CodeRabbit's assessment that i18n should be used for user-facing text. However, as the review correctly points out:

"Since all other providers in this file also use hardcoded strings, this should be addressed consistently in a separate refactor."

Why I'm not fixing this in this PR:

1. Consistency: All 6 embedding providers in EMBEDDING_PROVIDERS array use hardcoded strings (name, description)
2. Scope creep: Converting only OpenRouter to i18n while leaving the other 5 providers hardcoded would create inconsistency
3. Better as separate work: A dedicated PR to add i18n support for all embedding providers would be more appropriate and easier to review

Proposed follow-up:

• Create a separate issue/PR to add i18n keys for all embedding provider strings
• This would include: provider names, descriptions, API key labels, and help text
• Estimated scope: ~6 providers × 3-4 strings each = comprehensive i18n refactor

For now, I'm following the established pattern in the file to maintain consistency. The OpenRouter implementation is functionally complete and matches the existing code style.

Does this reasoning make sense?

OpenRouter Provider Support - Implementation Summary

This PR now includes complete OpenRouter support across both the Setup Wizard and Settings page, addressing the unresolved CodeRabbit conversation.

What was added:

1. Setup Wizard (MemoryStep.tsx) - Commit 1e0521f

• ✅ Added OpenRouter to EMBEDDING_PROVIDERS array
• ✅ API key input with show/hide toggle
• ✅ Validation requiring API key for OpenRouter
• ✅ Save to global settings (globalOpenRouterApiKey)
• ✅ Link to OpenRouter key management

2. Settings → Memory Page (SecuritySettings.tsx) - Commit cc4669d

• ✅ Added OpenRouter to embedding provider dropdown
• ✅ OpenRouter credential fields with password toggle
• ✅ Global key detection: Shows when using global key from App Settings
• ✅ Override support: Project-specific key can override global key
• ✅ Visual indicator with Globe icon when using global key

3. Type Definitions (project.ts)

• ✅ Added openrouterKeyIsGlobal?: boolean to ProjectEnvConfig
• ✅ OpenRouter already existed in GraphitiEmbeddingProvider union type

4. Consistency (MemoryBackendSection.tsx)

• ✅ Updated unused component for future use
• ℹ️ This component is part of refactoring effort but not actively rendered

Why this matters:

Before this PR:

• ❌ OpenRouter was in backend .env.example but missing from frontend UI
• ❌ Users couldn't configure OpenRouter through the app

After this PR:

• ✅ Complete UI support in Setup Wizard
• ✅ Complete UI support in Settings → Memory
• ✅ Auto-detection from backend .env (original PR feature)
• ✅ Global key with project override support

Testing performed:

1. ✅ Setup Wizard shows OpenRouter provider with API key input
2. ✅ Settings → Memory page shows OpenRouter in dropdown
3. ✅ Global key detection works (shows "Using global key" indicator)
4. ✅ Project-specific override works (can enter key to override global)
5. ✅ Build succeeds without errors

This implementation follows the exact same patterns used for OpenAI, Voyage, and other providers, ensuring consistency across the codebase.

Are you available to clear up the conflicts on this PR? Really looking forward to having this feature! :)

[g1331]

Hi! I took a closer look at the latest PR head because I’m really looking forward to this feature landing.

One potential gap I noticed: the Settings UI now lets users select OpenRouter and enter an API key, but the project env persistence layer in the main process (apps/frontend/src/main/ipc-handlers/env-handlers.ts) doesn’t appear to read/write any OPENROUTER_* variables (no matches for OPENROUTER_API_KEY, openrouterApiKey, or openrouterKeyIsGlobal).

So today it seems possible to persist GRAPHITI_EMBEDDER_PROVIDER=openrouter, but not persist the actual key into the project .auto-claude/.env (meaning it could be lost after restart, and memory init would fail unless the user also configured a global key).

Suggested fix (mirroring the existing OpenAI flow):

• In ENV_UPDATE / generateEnvContent(): write OPENROUTER_API_KEY (and optionally OPENROUTER_BASE_URL, OPENROUTER_EMBEDDING_MODEL) from graphitiProviderConfig.
• In ENV_GET: populate graphitiProviderConfig.openrouterApiKey from the project env, or fall back to globalOpenRouterApiKey, and set openrouterKeyIsGlobal accordingly.

Thanks again for the work on this PR — it’s super close, and I’m excited to have OpenRouter available in Settings once merged.
