Announcing Stream Chat’s New Java Backend SDK

Stream Chat’s newest backend SDK is now available, extending complete integration support to apps written in Java. This release brings the total number of backend frameworks with dedicated Stream Chat SDKs to seven (in addition to our REST API, which can be used to build unlimited custom integrations). Our SDK engineering teams are excited to invite peers working in the Java ecosystem to discover Stream Chat.

25 years after its creation, Java is still one of the most popular server-side programming languages in use. And thanks to a high volume of skilled Java developers in the workforce, continued growth in Android development, and the language’s portability, Java will likely remain popular for years to come. At Stream, Java backend support has been one of our most frequent feature requests, and we’re proud to deliver an enterprise-grade solution.

Stream Chat Backend SDKs vs. Frontend SDKs

Developers integrating Stream Chat for the first time are often surprised at how much of the heavy lifting is handled by our frontend SDKs, which connect directly to the Stream Chat API and save considerable amounts of time and effort. The average integration focuses mainly on code that executes in the client, with your choice of React, React Native, Android (Java or Kotlin), iOS, or Flutter as a starting point. A few key tasks must be executed on the server side, however, and this is where the backend SDK libraries come in handy as an alternative to calling the REST API directly with Axios or Curl.

These backend tasks include generating user tokens and syncing users. For many use cases, we also recommend that syncing channels and adding and removing members and moderators take place on the server side.
