distributed-morsel

Distributed tracing playground using a mock food delivery app.

Quick start

To see how the distributing tracing looks like, run docker-compose up in the root of this repo. It will start Jaeger (the "tracing browser") at http://localhost:16686.

The service traces in Jaeger will show up after running the demo 👇

Service names in Jaeger:

• dm-orders
• dm-restaurant
• dm-notifications

Demo

You can execute the flow by running 2 requests:

1. Put some items in your cart:

curl -X PATCH \
-H "Content-Type: application/json" \
-d '{"itemIds": [1,2]}' \
http://localhost:3000/cart

2. Check out your cart to create the order:

curl -X POST \
http://localhost:3000/cart/checkout

The orders app will then call the restaurant, which will in turn confirm the order by calling the notifications service.
