🔧 Architecture Overview

Three Core Layers

1. ROUTING LAYER
   ├─ Middleware: Subdomain extraction & tenant resolution
   ├─ Header injection: X-Tenant-Slug, X-Tenant-Id
   └─ Route groups: (tenant) for tenant-scoped pages

2. CONTEXT LAYER
   ├─ TenantProvider: React Context for tenant state
   ├─ useTenant() hook: Access tenant data in components
   └─ Automatic loading: From headers via DataProvider

3. PRESENTATION LAYER
   ├─ Landing page: Branded, industry-aware
   ├─ Tenant picker: Workspace selection hub
   └─ CSS variables: Dynamic theming

Data Flow

Request to subdomain.localhost:3000
    ↓
Middleware extracts subdomain
    ↓
Looks up tenant in DataProvider
    ↓
Injects X-Tenant-Slug header
    ↓
TenantProvider reads header
    ↓
Loads tenant data
    ↓
Landing page renders with branding

📋 Routing Model

URL Structure

integratewise.com            → Public ecosystem (future)
www.integratewise.com        → Same as apex
{tenant}.integratewise.com   → Tenant landing page + app
app.integratewise.com        → Workspace picker

Demo Workspaces (Local)

Subdomain	Name	Industry	URL
saas-corp	SaaS Corp	SaaS	http://saas-corp.localhost:3000
healthtech	HealthTech Inc	Healthcare	http://healthtech.localhost:3000
fintech-solutions	Fintech Solutions	Fintech	http://fintech-solutions.localhost:3000
app	Workspace Picker	Hub	http://app.localhost:3000

🚀 Next Steps

Immediate (Testing)

Start dev server: npm run dev
Visit demo workspaces locally
Test auth flows and navigation
Customize a tenant's branding

Short Term (Enhancement)

Add admin UI for tenant provisioning
Implement custom domain support
Add analytics/usage tracking

Long Term (Production)

Migrate to Neon PostgreSQL
Add Redis caching for slug lookups
Implement RLS policies for data isolation
Set up audit logging
Create admin dashboard

See TENANT_ROUTING_IMPLEMENTATION.md → Production Considerations for details.

💡 Key Concepts

Slug Validation

DNS-safe: lowercase alphanumeric + hyphens
Length: 2-63 characters
Pattern: ^[a-z0-9]([a-z0-9-]{0,61}[a-z0-9])?$
Reserved: www, app, api, admin, docs, localhost, staging, dev

Branding System

logoUrl: emoji or image URL displayed in navigation
primaryColor: hex color used for CTAs, accents
backgroundColor: hex color for page background
tagline: short description displayed under name

Landing Configuration

headline: main page heading
subhead: supporting text
featuredPluginIds: array of plugins to highlight
featuredAgentIds: array of agents to highlight

Tenant Status

active: Workspace is live and accessible
suspended: Workspace exists but access restricted
provisioning: Workspace being set up

Feature Overview: See DELIVERY_SUMMARY.md → Key Deliverables

Common Questions

Q: How do I add a new tenant?
A: Edit SEED_TENANTS in lib/data/in-memory-provider.ts and restart dev server. See QUICK_START_TENANT_ROUTING.md.

Q: How do I customize branding?
A: Update the branding object on your tenant. Colors apply via CSS variables. See QUICK_START_TENANT_ROUTING.md → Customizing Tenants.

Q: How do I deploy to production?
A: Migrate to persistent database (Neon) and add caching layer (Redis). See TENANT_ROUTING_IMPLEMENTATION.md → Production Considerations.

Q: Can I use custom domains?
A: Yes, the schema supports customDomain field. Middleware enhancement needed. See TENANT_ROUTING_IMPLEMENTATION.md → Custom Domains.
