# redpanda cloud demo
This repository contains a demo of how to connect to Redpanda Cloud using the
[KafkaJS](kafka.js.org) library.
## why?
If this application can run successfully targeting redpanda cloud, we should be
confident that it will work with Strimzi clusters deployed using CNDI.
## setup
1. Create a Redpanda Cloud cluster
2. Create a topic named `"roll"`
3. Create a user with all permissions
4. Get the username, password, and broker address for the user
```bash
# .env
KAFKA_USERNAME='foo'
KAFKA_PASSWORD='iwgno4gi5oign4woian4gio4w'
KAFKA_BROKER='w4gnwi4ngoi4wn.any.us-east-1.mpx.prd.cloud.redpanda.com:9092'
```
5. Run the application
```bash
deno task serve
```
6. Visit [localhost:8000/roll/yourname](http://localhost:8000/roll/anonymous)
7. if configured correctly, you should see a response which looks like
```jsonc
{
"username": "foo",
"roll": 1,
"region": "unknown",
"date": "2024-03-29T04:05:27.324Z",
"kafka_success": true,
"kafka_record": [
// this part will be missing if the kafka record was not saved
{
"topicName": "roll",
"partition": 0,
"errorCode": 0,
"baseOffset": "8",
"logAppendTime": "-1",
"logStartOffset": "-1"
}
]
}
```
8. If you'd like to listen for updates to the 'roll' topic, you can run the
`consume` application. Remember, this is cool because it can run anywhere -
it just happens to be on the same machine as the `serve` application.
```bash
deno task consume
```
