What have I learned?

In this project, the challenge was to put into practice what I've studied about Go and GRPC by creating a simple API. I also took the opportunity to refresh my knowledge of Docker and Docker Compose to run the entire application within Docker. Additionally, I wanted to use a database I had never worked with before, PostgreSQL.

The key takeaways and learnings from this project include:

• Pointers in Go
• Services and messages in .proto files
• Communication between two services within a container
• Understanding how GRPC facilitates communication.
