Project State

Project Reference

See: .planning/PROJECT.md (updated 2026-01-09)

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: Phase 12 - Model Improvements

Current Position

Phase: 11 of 12 (UI Polish) Plan: 1 of 1 complete Status: Phase complete Last activity: 2026-01-12 - Completed 11-01-PLAN.md

Progress: █████░░░░░ 42%

  • Trend: Fast execution with established 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)
  • 10-minute cache TTL for model lists
  • 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

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
