An example repo of how I like to use postgres with gRPC

First, start a postgres container:

$ docker run --rm -d --name postgres -p 5432:5432 -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=mypass -e POSTGRES_DB=postgres postgres:13

Start the server:

$ go run main.go --postgres-url postgresql://postgres:mypass@localhost:5432/postgres
...

INFO[May 21 22:51:37.156] Serving Web UI on https://localhost:10000

Navigate to http://localhost:10000 to see the auto-generated web UI for the service, courtesy of gRPC reflection and github.com/fullstorydev/grpcui!

Developing

Requirements

• go > 1.14

Run make install to install the generation dependencies:

$ make install

Making changes

After making any changes to the proto file or the migrations, make sure to regenerate the files:

$ make generate

If you want to change the schema of the database, add another migration file. Use the same naming format, with the new file names starting 2_. Make sure to run make generate and increment the migration version in users/helpers.go.
