Change Streams give the ability to applications monitor data-changes and react to this changes on a single collection, a database or an entire deployment.
If you want to run the code in this repository you will need to spin up fastify server
that produces new data changes in mongodb, a listener service that listen to data changes and of course you' ll need a mongodb in replica set or shared clusters.
I have provide a docker-compose.yml
file in order to run locally mongodb in replica set. For information on how to set it.
- Install dependencies by running
npm i
. - Start fastify-server with
npm run start:server
- Start on another cmd the listener with
npm run start:listener
I have provided a postman collection that you can use to do requests to
fastify-server or you can just use curl
command.
# Insert Event
curl -X POST -H "Content-Type: application/json" \
-d '{"message": "Hello World"}' \
http://localhost:5000/notification
# Update Event
curl -X PUT -H "Content-Type: application/json" \
-d '{"message": "test"}' \
http://localhost:5000/notification/<id>
# Delete Event
curl -X DELETE \
http://localhost:5000/notification/<id>
