Covers Gradle plugin configuration (kotlinMultiplatform, androidMultiplatformLibrary, serialization), declaring Android and iOS targets (iosArm64, iosSimulatorArm64), configuring commonMain and commonTest source sets with Ktor dependencies, and adding platform-specific HTTP engines (CIO for Android, Darwin for iOS). The module is designed to communicate with Firebase Authentication and Firestore REST APIs without relying on official KMP SDKs. ## Full article daily.dev links to this article rather than hosting it.
