Thalia book price tracker

Track the pricing of books over time.

Tech

Infrastructure

Nuxt is used as an integrated solution for the front and back end. The backend, based on Nitro endpoints, requests data from the Influx and Redis database and sends it to the frontend. If another book is to be tracked, a new schedule is inserted via BullMQ. Both the Nuxt application and the worker run using Bun.

The web, worker and proxy container can be scaled as pleased, because of the included "load balancing" of docker network using DNS.
