Deploy Sandy’s online shop. What we built, what comes next.

What We Built

Sandy’s online shop has:

Menu API — CRUD for menu items
Order API — Complex orders with nested models
Validation — Pydantic + custom processors
Error Handling — Structured errors with Result
DI — Database, cache, auth via pipeline
Middleware — Rate limiting, logging, timing
Testing — Direct pipeline testing

Running in Production

# Install EVOID
uv add evoid

# Run with production settings
evo service run sandy-api --host 0.0.0.0 --port 8000

What’s Next

Sandy’s shop is successful. But:

3 more locations are opening
Each location needs its own inventory
Orders need to sync between locations
Sandy wants AI-powered analytics

This is Phase 3 — the franchise.

Phase 3 Preview

# Native IOP style — full control
from evoid.native import create_service, on

orders_service = create_service("orders")
inventory_service = create_service("inventory")

# Inter-service communication via Message Bus
from evoid.core.message_bus import publish, subscribe

# Orders service publishes to inventory
await publish(
    Intent(name="order_placed", level=Level.STANDARD),
    source="orders",
)

# Inventory service subscribes
subscribe("order_placed", handle_stock_update)

Next: Multi-Location

Let’s scale Sandy to a franchise — Multi-Location.
