💻 Implementation Details

Stripe Configuration

// Example Stripe setup
const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY)

// Create checkout session
const session = await stripe.checkout.sessions.create({
  mode: 'subscription',
  payment_method_types: ['card'],
  line_items: [{
    price: priceMap[planId][billingInterval],
    quantity: 1,
  }],
  success_url: `${process.env.NEXT_PUBLIC_APP_URL}/settings?session_id={CHECKOUT_SESSION_ID}`,
  cancel_url: `${process.env.NEXT_PUBLIC_APP_URL}/settings`,
  client_reference_id: organizationId,
  metadata: { organizationId, planId, billingInterval }
})

API Key Generation

// Secure API key generation
const generateApiKey = () => {
  const prefix = 'spiq_live_'
  const randomBytes = crypto.randomBytes(32)
  const keyValue = prefix + randomBytes.toString('hex')
  return keyValue
}

Permission System

// Role-based permissions
const PERMISSIONS = {
  ADMIN: ['*'],
  MANAGER: ['manage:team', 'view:analytics', 'manage:sprints'],
  DEVELOPER: ['view:insights', 'manage:tasks', 'read:analytics'],
  VIEWER: ['view:dashboards', 'read:reports']
}
