Troubleshooting

Installation

Add one or more modules to your project

Available modules: auth-kt*, postgrest-kt, functions-kt, storage-kt, realtime-kt, apollo-graphql, compose-auth, compose-auth-ui, coil-integration, coil3-integration, imageloader-integration

dependencies {
    implementation("io.github.jan-tennert.supabase:[module]:VERSION")
}

* Before version 3.0.0, the module was called gotrue-kt.

If you use multiple modules, you can use the bom dependency to get the correct versions for all modules:

implementation(platform("io.github.jan-tennert.supabase:bom:VERSION"))
implementation("io.github.jan-tennert.supabase:[module]")

Add a Ktor Client Engine to each of your Kotlin targets

You can find a list of available engines here. If you plan to use the Realtime dependency, make sure to check if the engine supports WebSockets. See the Ktor docs for more information.

implementation("io.ktor:ktor-client-[engine]:VERSION")

Multiplatform Example

For targets: jvm, android, js, ios

val commonMain by getting {
    dependencies {
        //supabase modules
    }
}
val jvmMain by getting {
    dependencies {
        implementation("io.ktor:ktor-client-cio:KTOR_VERSION")
    }
}
val androidMain by getting {
    dependsOn(jvmMain)
}
val jsMain by getting {
    dependencies {
        implementation("io.ktor:ktor-client-js:KTOR_VERSION")
    }
}
val iosMain by getting {
    dependencies {
        implementation("io.ktor:ktor-client-darwin:KTOR_VERSION")
    }
