Section Two

Technology
Stack

Every technology choice, why it was chosen, and what it does.

07 Full Technology Stack

Layer	Technology	Version	Why This Choice
Frontend	Next.js (App Router)	14	Server-side rendering, React Server Components, SEO-ready. App Router gives layout nesting and streaming.
Backend API	NestJS	10	TypeScript-native, decorator-based, modular architecture. Built-in DI, Guards, Interceptors. Scales cleanly.
Language	TypeScript	5	End-to-end type safety. Shared types package ensures frontend/backend contract is never broken.
Database	PostgreSQL + PostGIS	15	Relational integrity for tenancy/payment data. PostGIS extension adds geospatial queries for future map features.
ORM	Prisma	7	Type-safe schema-as-code, auto-generated client, migration system. Single source of truth for DB shape.
Auth	JWT (access + refresh)	—	Stateless authentication. Access token (15 min) + refresh token (7 days) pattern. Bcrypt password hashing.
Payments	Stripe	—	Industry standard. Handles PCI compliance. Supports rent collection, subscriptions, deposits.
File Storage	MinIO	—	S3-compatible, self-hosted on the same VPS. No AWS dependency. Full data ownership.
Background Jobs	Bull + Redis	—	Queue-based job processing for email reminders, compliance alerts, PDF generation. Retries, scheduling.
Email	Nodemailer	—	Sends via SMTP. Rent reminders, compliance expiry alerts, maintenance updates.
Styling	Tailwind CSS	3	Utility-first. No CSS files to maintain. Consistent design tokens. Works perfectly with component patterns.
State (Frontend)	TanStack Query	5	Server state management. Caching, background refetch, optimistic updates. Replaces Redux for data fetching.
Reverse Proxy	Nginx	Alpine	Routes /api/* to NestJS, /* to Next.js. Cloudflare IP allowlist, rate limiting, security headers.
Containerisation	Docker + Compose	—	6-service stack runs identically in dev and production. No environment drift. Kubernetes-ready when needed.
CDN / DDoS	Cloudflare	—	Proxy in front of VPS. Handles SSL termination, DDoS protection, firewall rules.

08 System Architecture

How a request flows

🌐 Browser / Tenant App

↓

☁️ Cloudflare
SSL · DDoS · CDN

↓ HTTP (port 80)

🔀 Nginx
Reverse Proxy · Rate Limit
Cloudflare IP allowlist

↓ routes by path

⚛️ Next.js :3000
Web UI (SSR)

🔌 NestJS :3001
REST API + Auth

↓ Prisma ORM

🐘 PostgreSQL + PostGIS

⚡ Redis

📦 MinIO

Traffic rules (Nginx)

/api/auth/* → NestJS, strict rate limit (5 req/min)
/api/stripe/webhook → NestJS, no rate limit (Stripe needs raw body)
/api/* → NestJS, standard rate limit (30 req/sec)
/* → Next.js (SSR pages)

Security layers

Cloudflare proxy — only Cloudflare IPs accepted at Nginx (all others → 444)
JWT Bearer auth on every API route
RBAC — every endpoint gated by role
Bcrypt password hashing (salt rounds: 10)
Nginx security headers (X-Frame-Options, CSP-ready, nosniff)
PostgreSQL exposed only on 127.0.0.1 (not to internet)
Redis + MinIO internal-only (Docker network)

09 Database Schema — Core Models

Core Entities

Model	Key Fields	Purpose
User	email, passwordHash, role, isActive, refreshTokenHash	All platform users (all roles)
Property	address, type, ownerId, managerId, geom (PostGIS), isActive	Portfolio of managed properties
Tenancy	propertyId, tenantId, startDate, endDate, rentAmount, status, depositAmount	Tenancy agreements
Payment	tenancyId, amount, dueDate, paidAt, stripePaymentId, status	Rent payment records
ComplianceItem	propertyId, type (Gas/EICR/EPC…), expiryDate, status, alertSent	Certificate tracking
MaintenanceRequest	propertyId, tenantId, status, priority, contractorId, AwaaabDeadline	Repair jobs

Supporting Entities

Model	Key Fields
Document	propertyId, uploadedBy, fileKey (MinIO), type, category, fileSize
AuditLog	userId, action, entity, entityId, metadata (JSON), ipAddress, createdAt
Notification	userId, type, title, message, read, relatedEntity
Subscription	userId, stripeSubscriptionId, plan, status, currentPeriodEnd
MaintenancePhoto	requestId, fileKey, uploadedBy, stage (before/after)

Key Design Decisions

Single User model for all roles — role field determines access
PostGIS geometry column on Property — ready for map features without schema change
AuditLog is append-only — no updates or deletes permitted
Document files stored in MinIO by key — DB holds metadata only
Compliance expiry tracked at item level — allows per-certificate alert history
All monetary amounts stored as Decimal (not float) — no rounding errors
RefreshTokenHash on User — supports token rotation and invalidation on logout

Database

          # Connect

          Host: postgres (Docker internal)

          Port: 5432 (127.0.0.1 only)

          DB: nesteasy_db

          ORM: Prisma (migrate deploy)

API Module Structure (pattern)

# Each module follows this pattern:

src/modules/feature/

├── feature.module.ts     ← wires DI

├── feature.controller.ts ← HTTP routes + guards

├── feature.service.ts    ← business logic

└── dto/                  ← input validation

Frontend File Pattern

# Each feature:

src/lib/api/feature.ts    ← typed API client

src/components/dashboard/

  FeatureView.tsx       ← main component

src/app/(dashboard)/

  feature/page.tsx      ← route page (thin)

12 Developer Guide — Making a Backend Change

Adding or changing an API endpoint

1

Edit the Service

Add / modify business logic in feature.service.ts. This is where Prisma queries live.

2

Add the Route

Add @Get/@Post/@Patch in feature.controller.ts with correct @Roles() guard.

3

DB Change?

Edit prisma/schema.prisma, run pnpm prisma migrate dev --name description locally.

4

Build API Image

sudo docker compose build api from the docker/ directory.

5

Deploy

sudo docker compose up -d api — zero-downtime, migrations run automatically on startup.

🔐 Auth & Roles

Every controller uses @UseGuards(JwtAuthGuard, RolesGuard) at class level. Add @Roles(UserRole.ADMIN) on specific methods to restrict access. Use @CurrentUser() decorator to get the calling user.

📝 Audit Logging

Inject PrismaService and call this.prisma.auditLog.create() after significant mutations. Include userId, action (e.g. "CREATE_PROPERTY"), entity, entityId.

📧 Email / Queues

Inject EmailService to send transactional emails. For scheduled/background jobs, inject @InjectQueue('notifications') and add to the Bull queue with a delay.

13 Developer Guide — Making a Frontend Change

Adding a new UI page or feature

1

API Client

Add typed functions to src/lib/api/feature.ts using the apiClient axios wrapper. Always type the response.

2

Create Component

Add FeatureView.tsx in src/components/dashboard/. Use useQuery for data, useMutation for writes.

3

Create Route

Add page.tsx inside src/app/(dashboard)/feature/. Keep it thin — just renders the View component.

4

Build Image

sudo docker compose build web — Next.js builds to a standalone output inside the image.

5

Deploy

sudo docker compose up -d web — hot-swaps the web container, nginx continues serving.

🎨 Styling

Tailwind only — no custom CSS files. Use the cn() utility for conditional classes. Brand blue: #2563EB. Gray scale from gray-50 to gray-900.

📡 Data Fetching

Always use useQuery({ queryKey: ['feature', id], queryFn: api.get }). For mutations use useMutation + queryClient.invalidateQueries to refresh on success.

🔒 Role Gating

The Sidebar already fetches /users/me. Use useQuery(['users', 'me']) from the same cache to get the role in any component.

📱 Responsive

Use Tailwind responsive prefixes: sm:, md:, lg:. Dashboard has a fixed sidebar — on mobile consider a collapsible drawer (Phase 2).

14 Developer Guide — Deployment Workflow

Standard Deploy (change to api or web)

# 1. SSH into the VPS

ssh user@vps-ip

# 2. Pull latest code

cd ~/Nest/nest-easy

git pull origin main

# 3. Rebuild only changed service(s)

sudo docker compose -f docker/docker-compose.yml \

  build api          # or: web, or: api web

# 4. Restart the service

sudo docker compose -f docker/docker-compose.yml \

  up -d api

# 5. Verify logs

sudo docker logs nesteasy_api --tail 30

Check all services are healthy

sudo docker compose -f docker/docker-compose.yml ps

# All 6 should show: Up ... (healthy)

Database Migrations

# Migrations run AUTOMATICALLY on API startup

# (CMD in Dockerfile: prisma migrate deploy && node ...)

# To create a new migration (local dev):

cd apps/api

pnpm prisma migrate dev --name add_field

# NEVER run migrate dev on production

# Production ONLY uses: migrate deploy

Important Files — Don't Touch Without Understanding

docker/.env — compose variable substitution values
.env (root) — all secrets, JWT keys, Stripe keys
docker/nginx/nginx.conf — IP allowlist, rate limits
apps/api/prisma/schema.prisma — single source of truth for DB
apps/api/src/common/guards/ — JWT + RBAC guards, all routes depend on these

Useful Container Commands

docker exec nesteasy_postgres psql -U nesteasy nesteasy_db  ← DB shell

docker logs nesteasy_api -f                                 ← live API logs

docker exec nesteasy_api node_modules/.bin/prisma studio    ← DB GUI

15 Developer Guide — Environment & Secrets

Environment Variables (root .env)

Variable Group	Variables	Where Used
Database	POSTGRES_PASSWORD, DATABASE_URL	API container, Prisma
JWT	JWT_SECRET, JWT_REFRESH_SECRET, JWT_EXPIRES_IN	NestJS auth module
Stripe	STRIPE_SECRET_KEY, STRIPE_WEBHOOK_SECRET, STRIPE_PUBLISHABLE_KEY	API (payments module)
MinIO	MINIO_ACCESS_KEY, MINIO_SECRET_KEY, MINIO_BUCKET_NAME	API (documents module)
Email	SMTP_HOST, SMTP_PORT, SMTP_USER, SMTP_PASS	API (notifications module)
Frontend	NEXT_PUBLIC_API_URL, NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY	Baked into Next.js build

⚠️ NEXT_PUBLIC_ vars

These are baked into the Next.js build — changing them requires a full docker compose build web, not just a restart.

🔑 JWT Secrets

Changing JWT_SECRET invalidates ALL existing access tokens. Only change during a planned maintenance window — all users will need to re-login.

Two .env files

nest-easy/.env — loaded by API/web containers via env_file: in compose. Contains ALL secrets.
nest-easy/docker/.env — used by docker compose for ${VAR} substitution when building DATABASE_URL etc. Must stay in sync with root .env passwords.

Never commit

Either .env file (should be in .gitignore)
Any file containing sk_live_ or whsec_ keys
Database passwords
JWT secrets

✓ Best practice

Keep a password-manager entry for all production secrets. The .env.example file in the repo shows all keys with placeholder values.

Section Four

Client
Delivery

How to hand this over to Nest Easy in the right way.

17 Recommended Delivery Approach

Three stages to a clean handover

🎯

Stage 1 — Client Demo

Walk through the live platform. Show every module. Record the session. Let the client operate it themselves while screen-sharing. Gather initial feedback.

Outcome: signed-off feature walkthrough

🧪

Stage 2 — UAT Period

Give the client a 2-week User Acceptance Testing window. Set up a few test landlord, tenant, and manager accounts. They put data in, we fix any issues they raise.

Outcome: client confidence, bug fixes logged and resolved

🚀

Stage 3 — Go Live

CNAME the client's domain to the VPS. Point Cloudflare to the correct origin. Update the Nginx server_name. Flip the platform to live branding with real Stripe keys.

Outcome: platform live on nesteasy.co.uk

📋 Go-Live Checklist

Replace Stripe test keys with live keys
Set up real SMTP (SendGrid recommended)
Create admin account for client team
Load initial property & landlord data
Update Nginx server_name for client domain
Verify Cloudflare CNAME is correct

📄 What to Hand Over

Admin login credentials
Video walkthrough recording
User guide (Manager + Tenant)
This team briefing document
Technical architecture doc
Support contact / SLA agreement

🔐 Credentials Transfer

Create ADMIN account for their team leader
Never share .env via email — use 1Password or similar
Change all default passwords before handover
Revoke Agile Tech admin accounts post-handover (or keep as support access)

📞 Support Arrangement

Define a support retainer or break-fix rate
Monthly platform fee covers hosting + maintenance?
Phase 2 features = new project scope
Agree on SLA: response time for critical issues

18 Client Domain & DNS Switch

Current Setup → Production Domain

# Current URL (our subdomain):

https://nest.agiletechsolutions.co.uk

# Target (client's domain):

https://manage.nesteasy.co.uk

# or whatever subdomain they choose

Steps to switch domain

# Step 1: Update Nginx server_name

# In docker/nginx/nginx.conf, change:

server_name nest.agiletechsolutions.co.uk;

# to:

server_name manage.nesteasy.co.uk;

# Step 2: Restart Nginx

sudo docker compose restart nginx

# Step 3: Add CNAME in Cloudflare

# manage.nesteasy.co.uk → [VPS IP]

# Set Proxy status: Proxied (orange cloud)

Live Stripe Keys Switch

# In root .env, replace test keys:

STRIPE_SECRET_KEY=sk_live_...

STRIPE_WEBHOOK_SECRET=whsec_...

STRIPE_PUBLISHABLE_KEY=pk_live_...

# In docker/.env and root .env update

NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=pk_live_...

# Then rebuild web (pk is baked into build):

sudo docker compose build web && docker compose up -d web

# Set up Stripe webhook in dashboard:

# URL: https://manage.nesteasy.co.uk/api/stripe/webhook

⚠️ SMTP for Production

The current SMTP config is a placeholder. Before go-live, configure a real email provider. We recommend SendGrid (free tier: 100 emails/day, reliable deliverability). Update SMTP_HOST, SMTP_PORT, SMTP_USER, SMTP_PASS in .env and restart the API.
