Generate better prompts, get better AI results.

Tech: Next.js App Router, TypeScript, TailwindCSS, shadcn/ui, Appwrite (Auth + DB), React Query, Google Gemini (REST).

• / Landing
• /login Auth (email/password + Google OAuth)
• /dashboard Prompt Builder + Recent
• /library Saved prompts with search/filters
• /settings Profile, theme note, export

Copy .env.example and set:

• NEXT_PUBLIC_APPWRITE_ENDPOINT
• NEXT_PUBLIC_APPWRITE_PROJECT_ID
• NEXT_PUBLIC_APPWRITE_DATABASE_ID ← used by client queries
• NEXT_PUBLIC_APPWRITE_COLLECTION_PROMPTS_ID← used by client queries
• APPWRITE_API_KEY
• APPWRITE_DATABASE_ID
• APPWRITE_COLLECTION_PROMPTS_ID
• GEMINI_API_KEY

Note: In this environment, .env is for configuration only; server-side variables are read at runtime.

• Database: promptcraft_db (use its ID in APPWRITE_DATABASE_ID)
• Collection: prompts (use its ID in APPWRITE_COLLECTION_PROMPTS_ID)
• Attributes:
  • userId string required
  • modelTarget string required
  • useCase string required
  • inputs object/JSON required
  • refinedPrompt string required
  • title string required
  • createdAt string required
• Permissions: user read/write on own docs.
• Auth: Email/password and Google OAuth enabled.

• POST /api/generate (Edge)
  • Validates payload (zod)
  • Rate limit: 20/min per IP (in-memory)
  • Calls Gemini 1.5 Flash via REST
  • Returns { refinedPrompt, tokensUsed, model }
• POST /api/savePrompt (Node)
  • Auth via Appwrite JWT in Authorization: Bearer <jwt>
  • Saves document with fields: { userId, modelTarget, useCase, inputs, refinedPrompt, title, createdAt }
• GET /api/exportMyPrompts (Node)
  • Auth via JWT, returns all user prompts JSON

Test payload for /api/generate:

``` { "targetModel": "ChatGPT", "useCase": "Text", "roughIdea": "Write a blog on beginner-friendly strength training tips", "context": "Audience is 18-25, limited equipment, motivation needed", "audience": "Gen Z beginners", "tone": ["motivational", "friendly"], "outputFormat": "outline", "constraints": ["900-1200 words", "avoid jargon"], "language": "English", "negative": "No dangerous advice" } ```

• shadcn/ui components (Button, Input, Textarea, Select, Tabs, Card, Badge, Dialog, DropdownMenu, Sheet, Toaster)
• Responsive, dark/light mode compatible
• Rounded-2xl cards and soft shadows
• Navbar with model switcher and user menu; collapsible sidebar on mobile

• Keep secrets out of logs.
• Inputs are sanitized and validated with zod.
• Edge vs Node: Gemini route is Edge; Appwrite save/export are Node.
