Both a simple graphQL enabled ReactJS app built using create-react-app AND a simple Java backend graphQL service built with Spring Initializr and using The Netflix DGS framework PLUS Astra DB hooked up and ready to rock! 😻

This is a companion to our Netflix Clone using Astra DB and GraphQL workshop and is essentially a “prologue” to that content. Once complete, feel free to to go deploy a Netflix clone using what you learned here.

Finally, this content uses React/JS concepts. If you are not familiar with those or need a refresher, take a look HERE to get up to date.

The materials have been built by the DataStax developer advocates team.

Use the following values when creating the database

Field Value
database name netflix_workshop_db
keyspace netflix_keyspace
Cloud Provider Use the one you like, click a cloud provider logo, pick an Area in the list and finally pick a region.

You can technically use whatever you want and update the code to reflect the keyspace. This is really to get you on a happy path for the first run.

You will see your new database pending OR initializing in the Dashboard.


The status will change to Active when the database is ready, this will only take 2-3 minutes. You will also receive an email when it is ready.
