Core value: Provider infrastructure that dynamically discovers models from external APIs, enabling users to access hundreds of image/video generation models without hardcoding schemas. Current focus: Testing and modularization (v1.2)

Current Position

Phase: 17 of 20 (Component Tests) Plan: 1 of 11 in current phase Status: In progress Last activity: 2026-01-13 - Completed 17-01-PLAN.md

Progress: ████████░░ 81%

• Trend: Larger refactoring tasks take longer but establish patterns

Accumulated Context

Decisions

Decisions are logged in PROJECT.md Key Decisions table. Recent decisions affecting current work:

• Gemini always enabled via env var (GEMINI_API_KEY), Replicate/fal.ai optional
• API keys stored in localStorage under node-banana-provider-settings key
• Local state in modal to avoid saving on every keystroke
• Provider config pattern: {id, name, enabled, apiKey, apiKeyEnvVar?}
• Provider registry uses self-registration pattern via registerProvider()
• Gemini remains special-cased in /api/generate for now, not yet migrated
• Capability inference from model name/description keywords
• fal.ai API key optional (works without but rate limited)
• fal.ai auth header: "Key {apiKey}" format (not Bearer)
• fal.ai category maps directly to ModelCapability (no inference)
• 1-hour cache TTL for model lists (extended from 10 min)
• Unified API at /api/models with header-based auth
• Provider dropdown shows Gemini always, others only if API key configured
• Aspect ratio/resolution controls shown only for Gemini provider
• Backward compatibility via aliases: NanoBananaNode, saveNanoBananaDefaults
• Server-side provider execution in API route (not client-side)
• Header-based API key passing: X-Replicate-API-Key, X-Fal-API-Key
• fal.ai sync API (fal.run) instead of queue-based async
• Dual migration approach: loadWorkflow migrates + UI effect for runtime
• fal.ai icon always visible in action bar (works without key but rate limited)
• Replicate icon only visible when API key is configured
• Client-side search filtering for Replicate (their search API unreliable)
• Show all capability badges to differentiate similar models
• Extract variant suffix from fal.ai model IDs for display name
• No TTL for image store - explicit cleanup pattern (callers delete after use)
• 256KB threshold for shouldUseImageUrl (Replicate recommendation)
• Gemini excluded from video node (doesn't support video generation)
• Large videos (>20MB) return URL instead of base64 to avoid memory issues
• Fetch schema from provider API at model selection time with 10-min cache
• Filter internal params, prioritize user-relevant ones (seed, steps, guidance)
• Collapsible parameters section to keep node UI compact
• Node autosizing constraints: 200-500px width, 200-600px height, ~100px chrome
• Provider badges prepend node title (left side) with w-4 h-4 icons
• Node titles show only model name (no "Generate Image/Video" prefix)
• BaseNode supports titlePrefix prop for icon prepending
• Header aligned for saved/unsaved states with same icon layout
• isImageInput() uses word-boundary checks (not substring) to avoid matching num_images
• Workflow execution gets fresh node data from store (not stale captured array)
• regenerateNode includes parameters in request body
• MD5 content hashing for generation deduplication (fast, collision resistance not critical)
• Hash prefix in filename for O(1) duplicate lookup
• Normalized handle IDs (image, text, image-0) for connection stability across model changes
• Handle-to-schema mapping built at execution time from inputSchema
• Placeholder handles (dimmed 30%) for input types not used by model, preserving connections
• ReactFlowProvider wrapper for component tests using @xyflow/react hooks
• Zustand store mocking with vi.mock pattern returning mocked functions
• Vitest jsdom environment for React component tests
• Store utilities extracted to src/store/utils/ with re-exports for backward compatibility
• Consolidated defaultNodeDimensions (was duplicated in addNode and createGroup)
• localStorage mocking pattern for testing utility modules

Deferred Issues

• UAT-001: Resolved - Provider icons now use real Replicate/fal.ai logos
• ISS-001: Resolved - Generate nodes now adapt to model requirements via dynamic parameters

Blockers/Concerns

• Pre-existing lint configuration issue (ESLint not configured). Not blocking development.

Roadmap Evolution

• v1.0 Multi-Provider Support shipped: 6 phases (Phase 1-6), 15 plans
• Milestone v1.1 Improvements created: 6 phases (Phase 7-12), improvements and polish
• Phase 13 added: Fix duplicate generations (hashing failure investigation)
• Phase 14 added: Fix drag-connect node creation bugs (consolidated from two phases)
• Milestone v1.2 Improvements created: 6 phases (Phase 15-20), testing and modularization
