Build Your First App with JavaScript, Node.js, and DataStax Astra DB

This is the first of a three-part app development workshop series designed to help developers understand technologies like Node.js, GraphQL, React, Netlify, and JavaScript to kickstart their app development portfolio. In this post, we’ll cover the fundamental concepts of website applications and introduce DataStax Astra DB as your free, fast, always-on database based on Apache Cassandra®.

In the U.S. we spend almost 88% of our mobile internet time buried in apps like Facebook, Instagram, TikTok, and games. With nearly a million new apps released each year and 218 billion app downloads in 2020, learning how to build them is an essential step in any front-end developer’s career.

Bring Streaming to Apache Cassandra with Apache Pulsar

Twitch, YouTube, Instagram, Facebook — virtually every major brand nowadays uses live streaming to connect and engage their audience. For enterprises and developers building cloud-native applications, this growing trend creates a need for streaming technologies that can reliably handle the rush of massive amounts of data, while also being flexible and easy to manage for developers.

One such technology is Apache Pulsar® — an open-source, distributed messaging and streaming platform that’s easy to deploy, simple to scale, and packed with developer-friendly APIs. So the next question is: how can you stream from Pulsar to Apache Cassandra®, the powerful NoSQL database designed to support data-heavy applications in the cloud?

Join our beginner-friendly Pulsar workshop on YouTube and learn how to connect Pulsar with Cassandra for streaming! In this post, we’ll set the scene with an introduction to Pulsar and guide you through four hands-on exercises where you’ll use these free, cloud-native technologies: Katacoda, Kesque, GitPod, and DataStax Astra DB. Each exercise will also be linked to the step-by-step instructions on the DataStax Developers GitHub wiki.

Building Reactive Java Applications with Spring Framework

If you’re a Java developer who uses the Spring ecosystem, you’ve probably seen the Spring Pet Clinic. In this workshop, we will walk you through a new reactive implementation of the Pet Clinic backend that uses Spring WebFlux and Apache Cassandra® (via DataStax Astra DB).

The cloud-native database-as-a-service built on Cassandra fits the highly concurrent, non-blocking nature of our reactive application. We’ll do all of our work in the cloud with Gitpod’s open-source, zero-install and collaborative development environment.
