The app is a microservice architecture based on NestJS. The communication between the microservices is done by REDIS and TCP.
The database that has been used is MongoDB. In order to more optimized queries, orders are mapped into collections proposed by author.
- gateway <-> Orders - Redis based on Cron Jobs (fetching data from provided API)
- gateway <-> Products - TCP
The data are fetched once a day from orders service that are triggered from a queue. To achieve it the app uses cron jobs and REDIS queue from gateway. The jobs are triggered in gateway.
Unfortunatelly due to issues with Redis in proposed solutions inside my docker compose
I couldn't dockerize the app at all. However running db, redis containers by using
command below works
docker compose up db redis -dI did my best to make it work, but I couldn't. Doing these way will be required run each service separately. and use localhost instead container name.
Before you'll do it remember about copy .env.example to .env.
Here is a generated collection of endpoints.
