This project consists of a pair of fastAPI apis, one that publishes simple
messages to an SNS topic and one that listens to the topic via HTTP. I did
this to gain familiarity with the subject and perhaps to use the code as
templates or guidance later on.
To start both APIs you can use docker-compose:
docker-compose upThis will start both services. The publisher listens on port 8000 and the
subscriber listens on 3000. The publisher will publish any messages posted
to it to SNS. Both services have documentation URL /redoc.
In order to test locally with SNS, you must make the subscriber's port
public. You can do this with ngrok:
ngrok http 3000Remember to add the ngrok URL to the subscriber's .env file!
