You need to first have a running kafka cluster with a ‘btc-price’ topic.

1. First run questDB on docker using

   docker run -p 9000:9000 -p 9009:9009 questdb/questdb

2. Then run the producer server For the producer you also need to add a .env file containing your CryptoCompare API key as such CC_API_KEY=<YOUR API KEY>

   cd serveur-btc
   pnpm i
   pnpm start

3. Run the consumer server

   cd consumer
   pnpm i 
   pnpm start

4. Run the frontend

   cd client
   pnpm i
   pnpm start

Go to http://localhost:5173 . Refreshing the webpage will cause the consumer to break. If this happens re run the consumer and refresh the webpage.
