KMP Passenger API

Overview

The KMP Passenger API Library is an open-source Kotlin Multiplatform project designed to provide a comprehensive suite of models and classes for interacting with the ioki passenger APIs.

Currenly supported platforms:

• Apple (iOS, macOS)
• JVM
• Android

Features

• Multiplatform Support: Leverage the power of Kotlin Multiplatform to run your API interactions on any device.
• Comprehensive Models: Includes a wide range of pre-defined models for passenger data, making API requests simpler and more intuitive.
• Easy API Requests: Simplified classes and functions for making API requests, handling responses, and managing errors.
• Open Source: Freely available for use and contribution, fostering community improvements and enhancements.

Getting Started

To include the KMP Passenger API Library in your project, add the following dependency to your build.gradle.kts file:

// Ensure you have the Kotlin Multiplatform plugin applied to your project
plugins {
    kotlin("multiplatform")
}

// The library is hosted on mavenCentral
repositories {
    mavenCentral()
}

val commonMain by getting {
    dependencies {
        implementation("com.ioki:passenger-api:$currentVersion")
    }
}

Snapshots of the development version are available in Sonatype's snapshots repository.

repositories {
    maven(url = "https://central.sonatype.com/repository/maven-snapshots/")
}

val commonMain by getting {
    dependencies {
        implementation("com.ioki:passenger-api:$currentSnapshotVersion")
    }
}

Usage

After including the library in your project, you first have to create an instance of the IokiService like the following:

val iokiService: IokiService = IokiService(
    baseUrl: String = "https://**.io.ki"
    requestHeaders: RequestHeaders = RequestHeaders(**)
    accessTokenProvider: AccessTokenProvider = InMemoryAccessTokenProvider()
    incerceptors: Set<ApiErrorInterceptor> = setOf() // Optional
    timeOffsetProvider: TimeOffsetProvider = NoopTimeOffsetProvider // Optional
    logging: Logging? = { println(it) } // Optional
)

After that, you can communicate with it to make API calls:

val phoneNumber = ""
val request = ApiPhoneVerificationRequest(phoneNumber, null)
val phoneVerificationResult = iokiService.requestPhoneVerification(request)

The results of the API calls are wrapped into an ApiResult class. Which is just a small wrapper around ioki-mobility/Result. A basic usage could look like this:

when(phoneVerificationResult) {
    is Result.Success -> { /* Do somehing with the success ${phoneVerificationResult.value} */ }
    is Result.Error -> {
        // Do somehing with the error ${phoneVerificationResult.error}.
        // This error is one of the sub types `Api`, `Generic`, and `Connectivity`
    }
}

However, there are more functions on Result like map, successOrHandle, mapFailure, etc. Checkout the ioki-mobility/Result documentation to find out more.

Test artifact

This project provides a test artifact that can be used as a test dependency in your project. The test artifacts provide default implementations for the Services to easily create fakes for your tests. You can simply override the functions relevant for you and ignore the rest.

val fakeUserService = object : UserServiceFake() {
    // Only override what you need
    override suspend fun deleteUser(): ApiResult<Unit> = Result.Success(SuccessData(Unit))
}

Additionally, it provides helper functions to create APIObjects easily.

val rideResponse = createApiRideResponse()

Those match well with your tests:

val fakeCurrentRideService = object : FakeCurrentRideService() {
    override suspend fun getCurrentRide(): ApiResult<ApiRideResponse> = Result.Success(SuccessData(
        createApiRideResponse(
            version = 1,
            pickup = createApiLocation(
                latitude = 50.1174225,
                longitude = 8.668939,
            ),
            dropoff = createApiLocation(
                latitude = 50.109694,
                longitude = 8.6666095,
            ),
        )
    ))
}

ClassUnderTest(fakeCurrentRideService)

To include it in your project, add the following dependency to your build.gradle.kts file:

val commonTest by getting {
    dependencies {
        implementation("com.ioki:passenger-api-test:$currentVersion")
    }
}

Don't forget about local.properties

If you see this issue:

* What went wrong:
Could not determine the dependencies of task ':library:testDebugUnitTest'.
> SDK location not found. Define a valid SDK location with an ANDROID_HOME environment variable or by setting the sdk.dir path in your project's local properties file at '/Users/***/kmp-passenger-api/local.properties'.

Please provide the path to your Android SDK in the local.properties file in the root of the project. For example:
