Firebase AI Logic Integration

When to use this skill

• Add AI features: integrate generative AI features into your app
• Firebase projects: add AI to Firebase-based apps
• Text generation: content generation, summarization, translation
• Image analysis: image-based AI processing

Instructions

Step 1: Firebase Project Setup

# Install Firebase CLI
npm install -g firebase-tools

# Login
firebase login

# Initialize project
firebase init

Step 2: Enable AI Logic

In Firebase Console:

1. Select Build > AI Logic
2. Click Get Started
3. Enable the Gemini API

Step 3: Install SDK

Web (JavaScript):

npm install firebase @anthropic-ai/sdk

Initialization code:

import { initializeApp } from 'firebase/app';
import { getAI, getGenerativeModel } from 'firebase/ai';

const firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_PROJECT.firebaseapp.com",
  projectId: "YOUR_PROJECT_ID",
};

const app = initializeApp(firebaseConfig);
const ai = getAI(app);
const model = getGenerativeModel(ai, { model: "gemini-2.0-flash" });

Step 4: Implement AI Features

Text generation:

async function generateContent(prompt: string) {
  const result = await model.generateContent(prompt);
  return result.response.text();
}

// Example usage
const response = await generateContent("Explain the key features of Firebase.");
console.log(response);

Streaming response:

async function streamContent(prompt: string) {
  const result = await model.generateContentStream(prompt);

  for await (const chunk of result.stream) {
    const text = chunk.text();
    console.log(text);
  }
}

Multimodal (image + text):

async function analyzeImage(imageUrl: string, prompt: string) {
  const imagePart = {
    inlineData: {
      data: await fetchImageAsBase64(imageUrl),
      mimeType: "image/jpeg"
    }
  };

  const result = await model.generateContent([prompt, imagePart]);
  return result.response.text();
}

Step 5: Configure Security Rules

Firebase Security Rules:

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    // Protect AI request logs
    match /ai_logs/{logId} {
      allow read: if request.auth != null && request.auth.uid == resource.data.userId;
      allow create: if request.auth != null;
    }
  }
}

Output format

Project structure

project/
├── src/
│   ├── ai/
│   │   ├── client.ts        # Initialize AI client
│   │   ├── prompts.ts       # Prompt templates
│   │   └── handlers.ts      # AI handlers

└── .env.local               # API key (gitignored)

Best practices

1. Prompt optimization: write clear, specific prompts
2. Error handling: implement a fallback when AI responses fail
3. Rate Limiting: limit usage and manage costs
4. Caching: cache responses for repeated requests
5. Security: manage API keys via environment variables

Constraints

Required Rules (MUST)

1. Do not hardcode API keys in code
2. Validate user input
3. Implement error handling

Prohibited (MUST NOT)

1. Do not send sensitive data to the AI
2. Do not allow unlimited API calls
