🔧 API Endpoints to Implement

Analytics API

// src/app/api/analytics/route.ts
import { NextRequest, NextResponse } from 'next/server'
import { getServerSession } from 'next-auth'
import { authOptions } from '@/lib/auth'

export async function GET(req: NextRequest) {
  const session = await getServerSession(authOptions)
  if (!session) {
    return NextResponse.json({ error: 'Unauthorized' }, { status: 401 })
  }

  const searchParams = req.nextUrl.searchParams
  const range = searchParams.get('range') || '30d'

  // Implement analytics query logic here
  // Query MongoDB for usage data, costs, etc.

  return NextResponse.json({
    usageTrends: [],
    costAnalysis: [],
    modelDistribution: [],
    performanceMetrics: [],
    topProjects: [],
  })
}

API Keys Management

// src/app/api/api-keys/route.ts
import { NextRequest, NextResponse } from 'next/server'
import { getServerSession } from 'next-auth'
import { authOptions } from '@/lib/auth'
import { getCollection } from '@/lib/mongodb'
import { nanoid } from 'nanoid'

export async function POST(req: NextRequest) {
  const session = await getServerSession(authOptions)
  if (!session?.user) {
    return NextResponse.json({ error: 'Unauthorized' }, { status: 401 })
  }

  const { name, scopes, rateLimit, expiresIn } = await req.json()

  const apiKey = {
    id: nanoid(),
    key: `sk_${nanoid(32)}`,
    userId: session.user.id,
    name,
    scopes,
    rateLimit,
    expiresAt: expiresIn === '0' ? null : new Date(Date.now() + parseInt(expiresIn) * 24 * 60 * 60 * 1000),
    createdAt: new Date(),
    lastUsed: null,
    isActive: true,
  }

  const apiKeys = await getCollection('api_keys')
  await apiKeys.insertOne(apiKey)

  return NextResponse.json({ key: apiKey })
}

export async function GET(req: NextRequest) {
  const session = await getServerSession(authOptions)
  if (!session?.user) {
    return NextResponse.json({ error: 'Unauthorized' }, { status: 401 })
  }

  const apiKeys = await getCollection('api_keys')
  const keys = await apiKeys.find({ userId: session.user.id }).toArray()

  return NextResponse.json({ keys })
}

Admin Stats API

// src/app/api/admin/stats/route.ts
import { NextRequest, NextResponse } from 'next/server'
import { getServerSession } from 'next-auth'
import { authOptions } from '@/lib/auth'
import { getCollection } from '@/lib/mongodb'

export async function GET(req: NextRequest) {
  const session = await getServerSession(authOptions)
  if (!session?.user || (session.user as any).role !== 'ADMIN') {
    return NextResponse.json({ error: 'Unauthorized' }, { status: 401 })
  }

  const users = await getCollection('users')
  const projects = await getCollection('projects')
  
  const totalUsers = await users.countDocuments()
  const activeUsers = await users.countDocuments({ status: 'ACTIVE' })
  const totalProjects = await projects.countDocuments()

  return NextResponse.json({
    totalUsers,
    activeUsers,
    totalRevenue: 45780, // Calculate from Stripe
    totalProjects,
    apiCallsToday: 156789, // Calculate from logs
    systemHealth: 'healthy',
  })
}

  "_id": ObjectId,
  "id": "string",
  "key": "sk_xxxxx",
  "userId": "string",
  "name": "string",

}

📊 Monitoring & Logging

Recommended Tools

  1. Error Tracking: Sentry
  2. Performance: New Relic or Datadog
  3. Logs: Papertrail or Logtail
  4. Uptime: UptimeRobot or Pingdom
  5. Analytics: Mixpanel or Amplitude

Setup Sentry

npm install @sentry/nextjs
npx @sentry/wizard -i nextjs

Setup Error Boundaries

Create src/app/error.tsx:

'use client'

export default function Error({
  error,
  reset,
}: {
  error: Error
  reset: () => void
}) {
  return (
    <div className="min-h-screen flex items-center justify-center">
      <div className="text-center">
        <h2 className="text-2xl font-bold mb-4">Something went wrong!</h2>
        <button onClick={reset} className="btn btn-primary">
          Try again
        </button>
      </div>
    </div>
  )
}

🔐 Security Best Practices

1. Environment Variables

Never commit .env to git:

echo ".env" >> .gitignore

2. API Rate Limiting

Implement rate limiting for all public APIs:

import { rateLimit } from '@/lib/rate-limit'

export async function POST(req: NextRequest) {
  const ip = req.headers.get('x-forwarded-for') || 'unknown'
  const limited = await rateLimit(ip, 100) // 100 requests per minute
  
  if (limited) {
    return NextResponse.json({ error: 'Too many requests' }, { status: 429 })
  }
  
  // Handle request
}

3. Input Validation

Always validate inputs with Zod:

import { z } from 'zod'

const schema = z.object({
  name: z.string().min(1).max(100),
  email: z.string().email(),
})

const validated = schema.parse(body)

4. SQL Injection Prevention

Use parameterized queries (MongoDB is safe by default)

5. CORS Configuration

// next.config.js
module.exports = {
  async headers() {
    return [
      {
        source: '/api/:path*',
        headers: [
          { key: 'Access-Control-Allow-Origin', value: process.env.NEXT_PUBLIC_APP_URL },
          { key: 'Access-Control-Allow-Methods', value: 'GET,POST,PUT,DELETE,OPTIONS' },
          { key: 'Access-Control-Allow-Headers', value: 'Content-Type, Authorization' },
        ],
      },
    ]
  },
}

📦 Deployment Options

Vercel (Recommended)

# Install Vercel CLI
npm i -g vercel

# Deploy
vercel --prod

# Set environment variables
vercel env add NEXTAUTH_SECRET production
vercel env add DATABASE_URL production
# ... add all env vars

Docker

FROM node:18-alpine

WORKDIR /app

COPY package*.json ./
RUN npm ci --only=production

COPY . .
RUN npm run build

EXPOSE 3000

CMD ["npm", "start"]
docker build -t ai-saas .
docker run -p 3000:3000 --env-file .env ai-saas

AWS/GCP/Azure

Use their respective container services or serverless platforms

🧪 Testing

Run Tests

npm test
npm run test:e2e

Test OAuth

  1. Use ngrok for local testing: ngrok http 3000
  2. Update OAuth redirect URLs with ngrok URL
  3. Test complete flow

Load Testing

Use tools like:

  • Apache JMeter
  • k6
  • Artillery

📈 Performance Optimization

1. Database Indexes

// Create indexes for common queries
db.users.createIndex({ email: 1 })
db.projects.createIndex({ userId: 1, status: 1 })
db.api_keys.createIndex({ key: 1 })
db.analytics.createIndex({ userId: 1, timestamp: -1 })

2. Caching

import { redis } from '@/lib/redis'

// Cache expensive queries
const cacheKey = `user:${userId}:projects`
const cached = await redis.get(cacheKey)

if (cached) {
  return JSON.parse(cached)
}

const data = await fetchProjects(userId)
await redis.set(cacheKey, JSON.stringify(data), 'EX', 300) // 5 minutes

return data

3. Image Optimization

Use Next.js Image component:

import Image from 'next/image'

<Image src="/logo.png" width={200} height={50} alt="Logo" />
