This tutorial will explain how to build a gRPC web service using go-masonry/mortar step by step.

• You should be familiar with Protobuf, gRPC and REST / Swagger
  • Install everything related to gRPC starting here
• You should understand what Dependency Injection is
• Have access to Jaeger service - Optional
• Have access to Prometheus - Optional

1. Tutorial service API
2. Project structure and business logic
3. Dependency Injection and Mortar
4. Wiring/Instrumentation of everything together
5. Mortar Middleware (Tracing, Monitoring, etc)
6. Tests example
7. Makefile

You can create a local git repository and copy 01-api to it. Once you seen/understand the code, commit. Then copy 02-api contents to your directory. This will overwrite some code.

Repeat for each subsequent part. This way you will have git to show you what actually changed.

*** Make sure to adjust imports accordingly.

Read the docs of all 7 parts described above and clone the alternate-example. You'll find there almost the same code organized in a different way: there are 2 independent microservices and common module.
