RxData is Android mobile library for building reactive data flow in Android application.

Gradle is the only supported build configuration. Since 1.4 RxData is hosted on mavenCentral, in order to fetch the dependency, add the following lines to your project level build.gradle.kts:

allprojects {
    repositories {
        mavenCentral()
    }
}

And then to the module level build.gradle.kts:

dependencies {
    implementation 'com.revolut.rxdata:dod:1.5.16'
    implementation 'com.revolut.rxdata:core:1.5.16'
    implementation 'com.revolut.rxdata:scheduler:1.5.16'
}

You can add only the necessary modules. Core would be required everywhere for defining interfaces and working with models, but core only needed in data layer, where you are going to be implementing DataObservableDelegate.

Scheduler is completely optional library for Android modules.

For using snapshot dependencies use the separate repository:

allprojects {
    repositories {
        maven(url = "https://s01.oss.sonatype.org/content/repositories/snapshots/")
    }
}

You can find several examples of how RxData is used in Revolut application in this Revolut Tech article. Also, fully documentation TBD soon here.

Here is the exemplary code that get you started in your application:

private val observePortfolio: DataObservableDelegate<Any, String, Portfolio> = DataObservableDelegate(
    fromNetwork = {
        tradingService.getPortfolio()
            .flatMap { portfolioDto ->
                getConfig().map { stocksConfig -> portfolioDto.toDomain(stocksConfig) }
            }         
    }

    // You can define other network / memory / storage lambdas here
)

You can also take part in improving RxData codebase! We do appreciate community engagement in that project.

You can propose bugfix or improvement to this project by submitting a pull request.

When sharing the code, please make sure that your contribution follows the existing code convention to let keep the code clean and readable.
