QUIC Pub Sub

About

This project contains 3 services that communicate via QUIC:

1. Server (in /server)
2. Publisher (in /publisher)
3. Subscriber (in /subscriber)

• Publishers and Subscribers connect to the Server
• Publishers send periodic messages to the Server if and only if there are subscribers connected to the Server
• The Server sends out messages from Publishers to all connected Subscribers.

Running the apps

Generate TLS certificates before the first run:

bash gen_certs.sh

Build:

go build -o bin/server ./server
go build -o bin/publisher ./publisher
go build -o bin/subscriber ./subscriber

From the project root:

1. build the server

./bin/server

2. open publishers as subscribers from different shells:

./bin/publisher

./bin/subscriber

If the commands complain, run them with -help to see how to modify parameters.

Notes

Relationships

In each app:

• Package transport contains code for remote communication and passes data onto the app package if one exists,
• Package app contains the logical part of the server, excluding any data transport/RPC specifics.

Directories "internal"

Packages internal might not be necessary but they are here to signify (and enforce by the compiler) that code is not shared between each of the 3 services, as they all live in the same project. The code that is shared lives in pkg.

Loggers

Loggers are passed to constructors as arguments, not via Options, this is a todo.

Testing

go test ./...

Generate mocks if they need to change

go generate ./...
