Chasm embedder

Chasm is an experimental WebAssembly runtime built on Kotlin Multiplatform.

Key Features:

  • Kotlin Multiplatform solution.
  • Compatible with Android API 26+ and JVM JDK 17+.
  • Single threaded only.

Installation:

dependencies {
    testImplementation("at.released.wasm-sqlite-driver:sqlite-embedder-chasm:0.1-beta03")

    // Sqlite WebAssembly binary
    testImplementation("at.released.wasm-sqlite-driver:sqlite-android-wasm-emscripten-icu-349:0.7")
}

Usage:

val factory = WasmSqliteOpenHelperFactory(ChasmSqliteEmbedder) {
    // Configuration of the Chasm embedder
    embedder {
        sqlite3Binary = SqliteAndroidWasmEmscriptenIcu349
    }
}

Just like with the Chicory embedder, when used with a room, a single-threaded coroutine dispatcher should be used.

newSingleThreadContext("RoomDatabase").use { singleThreadContext ->
    val db = Room.databaseBuilder()
        .setDriver(wasmSqliteDriver)
        .setQueryCoroutineContext(singleThreadContext)
        .build()
    // …    
}
