Example application created for the presentation on GopherCon Russia 2019 (slides).
There are 3 versions of this application:
1.0- just HTTP handler2.0- using Watermill to handle payment initialization in the background3.0- using Watermill CQRS component for initializing payments and counting bookings
Database adapters (in memory in this case) and domain layer is shared by all application versions.
Warning: this repository is using some Watermill unreleased features, which are still not released, like NewPoisonQueueWithFilter or CorrelationIDWithAutogenerate. They are now on cqrs-fix branch and will be released in v0.4.0.
For v2.0 and v3.0 you need Kafka. You can use docker-compose to run it:
docker-compose up
If you need some help with docker-compose setup, you should check our article about local Golang development environment.
And then you should run cmd/main.go from application version which you want to run.
cd 3.0/cmd/
go run .
