## Description
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.
## Prerequisites
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](https://docs.mongodb.com/manual/changeStreams/#availability).
I have provide a `docker-compose.yml` file in order to run locally mongodb in replica set. [For information on how to set it](https://gist.github.com/asoorm/7822cc742831639c93affd734e97ce4f).
## Usage
- 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.
```bash
# 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/
# Delete Event
curl -X DELETE \
http://localhost:5000/notification/
```
