While ObjectBox has data observers and reactive extensions built-in, this project adds RxJava 3 support.

For general object changes, you can use RxBoxStore to create an Observable.

RxQuery allows you to interact with ObjectBox Query objects using:

• Flowable
• Observable
• Single

For example to get query results and subscribe to future updates (Object changes will automatically emmit new data):

Query<User> query = box.query().build();
RxQuery.observable(query).subscribe(this);

Grab via Gradle:

implementation "io.objectbox:objectbox-rxjava3:$objectboxVersion"

If you have previously used the ObjectBox RxJava library note the following changes:

• The location of the dependency has changed to objectbox-rxjava3 (see above).
• The package name has changed to io.objectbox.rx3 (from io.objectbox.rx).

This should allow using both versions side-by-side while you migrate your code to RxJava 3.
