diff-tour-example

A small example service for trying diff-tour: an order and checkout backend written in TypeScript. It has no dependencies (Node.js 23.6 or later runs the TypeScript directly).

npm test
npm start   # POST /orders/:id/checkout

Branches

• main: orders, checkout, a payment service client and a batch that reconciles pending payments
• feature/payment-retry: retries transient payment failures at checkout
• feature/coupons: coupon codes that discount an order at checkout
• feature/daily-sales: a daily sales report and a CLI that prints it

Layout

• src/orders/ orders and the checkout business logic
• src/payment/ client for the external payment service
• src/handlers/ mapping to and from HTTP requests
• src/jobs/ scheduled batch jobs
• src/app.ts dependency wiring
• db/migrations/ database schema (applied in numeric order at startup)
