将 Kotlin 库的依赖项添加到 Kotlin/Wasm 项目

You can use the Kotlin standard library (stdlib) and test library (kotlin.test) in Kotlin/Wasm out of the box. The version of these libraries is the same as the version of the kotlin-multiplatform plugin.

Other official Kotlin (kotlinx) and multiplatform libraries are not fully supported yet. You can try experimental versions of such libraries by adding the Kotlin experimental repository to your Gradle project.

For Kotlin 1.9.0 and later, use the latest available libraries’ versions.

Supported Kotlin libraries for Kotlin/Wasm

You can use one of the following repositories to add Kotlin libraries to your project:

• Maven Central for stdlib and kotlin.test libraries:

  // build.gradle.kts
  repositories { 
      mavenCentral()
  }

• Custom Maven repository for experimental Kotlin/Wasm artifacts:

  // build.gradle.kts
  repositories {
      maven("https://maven.pkg.jetbrains.space/kotlin/p/wasm/experimental")
  }

• Custom Maven repository for Compose Multiplatform dev artifacts:

  // build.gradle.kts
  repositories {
      maven("https://maven.pkg.jetbrains.space/public/p/compose/dev/")
  }

Enable libraries in your project

To set a dependency on a library, such as kotlinx.serilization and kotlinx.coroutines, update your build.gradle.kts file:

// `build.gradle.kts`
repositories {
    maven("https://maven.pkg.jetbrains.space/kotlin/p/wasm/experimental")
}
kotlin {
    sourceSets {
        val wasmMain by getting {
            dependencies {
                implementation("org.jetbrains.kotlinx:kotlinx-serialization-core-wasm:1.5.1-wasm0")
                implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core-wasm:1.6.4-wasm0")
                implementation("io.ktor:ktor-client-core-wasm:2.3.1-wasm0")
            }
        }
    }
}
