Add proper dependency management in shared module +2. Implement comprehensive testing for all platforms +3. Add proper error handling in server endpoints +4. Use configuration files for server settings +5. Implement security measures for server (CORS, authentication) +6. Enhance logging configuration +7. Add more inline documentation +8. Consider adding a CI/CD pipeline configuration + +## Conclusion +The Meldestelle project demonstrates a well-structured Kotlin Multiplatform application targeting Web, Desktop, and Server. The project effectively shares code between platforms while allowing for platform-specific implementations. With some improvements in areas like testing, error handling, and configuration, the project could be more robust and production-ready. \ No newline at end of file diff --git a/gradle/libs.versions.toml b/gradle/libs.versions.toml index c8cb8baa..ad373dd8 100644 --- a/gradle/libs.versions.toml +++ b/gradle/libs.versions.toml @@ -8,6 +8,7 @@ ktor = "3.1.2" ktor-tests = "2.3.13" logback = "1.5.18" junit-jupiter = "5.12.0" +junit-jupiter-version = "5.8.1" [libraries] kotlin-test = { module = "org.jetbrains.kotlin:kotlin-test", version.ref = "kotlin" } @@ -24,6 +25,10 @@ ktor-server-tests = { module = "io.ktor:ktor-server-tests-jvm", version.ref = "k junit-jupiter = { group = "org.junit.jupiter", name = "junit-jupiter", version.ref = "junit-jupiter" } jupiter-junit-jupiter = { group = "org.junit.jupiter", name = "junit-jupiter", version.ref = "junit-jupiter" } +# ... andere libraries ... +ktor-server-config-yaml = { module = "io.ktor:ktor-server-config-yaml", version.ref = "ktor" } +junit-junit-jupiter = { group = "org.junit.jupiter", name = "junit-jupiter", version.ref = "junit-jupiter-version" } + [plugins] composeMultiplatform = { id = "org.jetbrains.compose", version.ref = "compose-multiplatform" } composeCompiler = { id = "org.jetbrains.kotlin.plugin.compose", version.ref = "kotlin" } diff --git a/server/build.gradle.kts b/server/build.gradle.kts index 278a232b..40eb70c0 100644 --- a/server/build.gradle.kts +++ b/server/build.gradle.kts @@ -20,4 +20,6 @@ dependencies { testImplementation(libs.kotlin.test.junit) testImplementation(libs.junit.jupiter) testImplementation(libs.jupiter.junit.jupiter) + implementation(libs.ktor.server.config.yaml) + testImplementation(libs.junit.junit.jupiter) } \ No newline at end of file diff --git a/server/src/main/kotlin/at/mocode/Application.kt b/server/src/main/kotlin/at/mocode/Application.kt index bc5af732..c9ffbf12 100644 --- a/server/src/main/kotlin/at/mocode/Application.kt +++ b/server/src/main/kotlin/at/mocode/Application.kt @@ -1,14 +1,12 @@ package at.mocode import io.ktor.server.application.* -import io.ktor.server.engine.* import io.ktor.server.netty.* import io.ktor.server.response.* import io.ktor.server.routing.* -fun main() { - embeddedServer(Netty, port = SERVER_PORT, host = "0.0.0.0", module = Application::module) - .start(wait = true) +fun main(args: Array) { + EngineMain.main(args) } fun Application.module() { @@ -17,4 +15,4 @@ fun Application.module() { call.respondText("Ktor: ${Greeting().greet()}") } } -} \ No newline at end of file +} diff --git a/server/src/main/resources/application.yaml b/server/src/main/resources/application.yaml new file mode 100644 index 00000000..6ae0785d --- /dev/null +++ b/server/src/main/resources/application.yaml @@ -0,0 +1,19 @@ +# Grundkonfiguration für Ktor in YAML + +ktor: + deployment: + # Der Port, auf dem der Server lauschen soll + port: 8080 + # port: ${PORT:8080} # Alternative: Nutzt Env-Variable PORT, sonst 8080 + # Optional für Entwicklung: Server bei Änderungen neu laden + # watch: + # - classes + # - resources + + application: + # Hier wird Ktor gesagt, welche Funktion die Konfiguration enthält + # PASSE DEN PFAD AN, falls deine Application.kt oder module() anders heißt/liegt! + modules: + - at.mocode.ApplicationKt.module + # Wenn Application.kt direkt unter at.mocode liegt: + # - at.mocode.ApplicationKt.module \ No newline at end of file diff --git a/server/src/test/kotlin/at/mocode/ApplicationTest.kt b/server/src/test/kotlin/at/mocode/ApplicationTest.kt index e72b6d6a..ee140a04 100644 --- a/server/src/test/kotlin/at/mocode/ApplicationTest.kt +++ b/server/src/test/kotlin/at/mocode/ApplicationTest.kt @@ -1,15 +1,27 @@ package at.mocode -import org.junit.jupiter.api.Assertions.* -import org.junit.jupiter.api.Test +import io.ktor.client.request.* +import io.ktor.client.statement.* +import io.ktor.http.* +import io.ktor.server.testing.* // Wichtig für testApplication +import kotlin.test.* // Wichtig für assertEquals, assertTrue etc. class ApplicationTest { - @Test - fun main() { - } @Test - fun module() { + fun testRootRoute() = testApplication { + application { + module() // Ruft deine Konfigurationsfunktion auf + } + + // Sendet eine GET-Anfrage an "/" innerhalb der Test-App + val response = client.get("/") + + // Überprüfungen (Assertions) + assertEquals(HttpStatusCode.OK, response.status, "Status Code should be OK") + val content = response.bodyAsText() // Holt den HTML-Body als Text + assertTrue(content.contains("Ktor: Hello, Java 21.0.6!"), "Welcome message missing") + } } \ No newline at end of file diff --git a/shared/src/commonMain/kotlin/at/mocode/Constants.kt b/shared/src/commonMain/kotlin/at/mocode/Constants.kt index 7c8324fb..df16304f 100644 --- a/shared/src/commonMain/kotlin/at/mocode/Constants.kt +++ b/shared/src/commonMain/kotlin/at/mocode/Constants.kt @@ -1,3 +1 @@ package at.mocode - -const val SERVER_PORT = 8080 \ No newline at end of file
