Y, a golang publish-subscribe platform using websockets and Postgres as message queue!

How to build, test and run

Having make command installed is a prerequisite.

• Building:

  make services

• Running tests:

  make test

• Test coverage (will open a tab in the browser):

  make coverage

• Run project:

  make run

For both, running the tests as well as checking the test coverage, make sure you have the database running. You can do that by spinning up all the project with make run or just the database with docker compose up db

Usage

Spinning up

First spin up the project with make run

Adding subscribers

Then you can start adding subscribers. For that, switch to subscriber directory and run

go run . -addr="localhost:8081" -user-id="a48bd304-7101-47e7-95ed-087b9b3a7f8d"

You can add multiple subscribers, each on a new terminal session. If you try to subscribe twice the same subscriber ID you'll get an error (Try it out : ) )

Publishing messages

To publish messages switch to journalist directory in a new terminal and run

go run . -addr="localhost:8080"

You can automate the process of publishing messages running the binary setting the auto flag to true:

go run . -addr="localhost:8080" -auto=true
