# MMKV for Kotlin Multiplatform
中文版本请参看[这里](https://github.com/ctripcorp/mmkv-kotlin/blob/master/README_CN.md)
MMKV for Kotlin Multiplatform is a wrapper for [MMKV](https://github.com/ctripcorp/mmkv-kotlin/blob/master/https://github.com/Tencent/MMKV) using Kotlin API, developed by Ctrip Flight mobile team. Currently Android/iOS/macOS are supported.
## Tutorial
### Installation Via Maven in Gradle
Kotlin Multiplatform Common (kts):
```kotlin
dependencies {
implementation("com.ctrip.flight.mmkv:mmkv-kotlin:1.2.10")
}
```
Current version based on `Kotlin 1.9.21` and `MMKV 1.3.2`.
Pure Android platform (kts):
```kotlin
dependencies {
implementation("com.ctrip.flight.mmkv:mmkv-kotlin-android:1.2.10")
}
```
Kotlin/Native on macOS：
```kotlin
dependencies {
// Intel Chip
implementation("com.ctrip.flight.mmkv:mmkv-kotlin-macosx64:1.2.10")
// M1&M2 Chip
implementation("com.ctrip.flight.mmkv:mmkv-kotlin-macosarm64:1.2.10")
}
```
Note, if your project is a Kotlin/Native executable program project of macOS or it supply a framework to a iOS application project directly, then you need to manually add dependency on MMKV, and may need add `linkerOpts` on MMKV and MMKVCore：
```kotlin
kotlin {
macosX64 {
binaries {
// ......
all {
val moduleName = "mmkv_operator"
val mmkvPath = "${buildDir.absolutePath}/cocoapods/synthetic/OSX/$moduleName/build/Release/MMKV"
val mmkvCorePath = "${buildDir.absolutePath}/cocoapods/synthetic/OSX/$moduleName//build/Release/MMKVCore"
linkerOpts += listOf(
"-F$mmkvPath",
"-rpath", mmkvPath,
"-framework", "MMKV",
"-F$mmkvCorePath",
"-rpath", mmkvCorePath,
"-framework", "MMKVCore"
)
}
}
}
cocoapods {
// ......
pod(name = "MMKV") {
version = "1.2.16"
moduleName = "MMKV"
}
}
// ......
}
```
### Initialization and Configure Root Path
You can initialize MMKV when app or process initialization. [MMKV-Android](https://github.com/ctripcorp/mmkv-kotlin/blob/master/https://github.com/Tencent/MMKV/tree/master/Android/MMKV) initialization API depends on [Context](https://github.com/ctripcorp/mmkv-kotlin/blob/master/https://developer.android.com/reference/android/content/Context). So, Android's initialization API is different from iOS.
Android:
```kotlin
import com.ctrip.flight.mmkv.initialize
// In Android source set
fun initializeMMKV(context: Context) {
val rootDir = initialize(context)
Log.d("MMKV Path", rootDir)
}
```
iOS:
```kotlin
import com.ctrip.flight.mmkv.initialize
// In iOS source set
fun initializeMMKV(rootDir: String) {
initialize(rootDir)
println("MMKV Path: $rootDir")
}
```
You also could call [MMKV-Android](https://github.com/ctripcorp/mmkv-kotlin/blob/master/https://github.com/Tencent/MMKV/tree/master/Android/MMKV) (Java) or [MMKV-iOS](https://github.com/ctripcorp/mmkv-kotlin/blob/master/https://github.com/Tencent/MMKV/tree/master/iOS) (Objective-C) initialization API in your Android or iOS app project.
### CRUD Operations
- MMKV has a **global instance**, you can use it directly:：
```kotlin
import com.ctrip.flight.mmkv.defaultMMKV
fun demo() {
val kv = defaultMMKV()
kv.set("Boolean", true)
println("Boolean: ${kv.takeBoolean("Boolean")}")
kv.set("Int", Int.MIN_VALUE)
println("Int: ${kv.takeInt("Int")}")
kv.set("Long", Long.MAX_VALUE)
println("Long: ${kv.takeLong("Long")}")
kv.set("Float", -3.14f)
println("Float: ${kv.takeFloat("Float")}")
kv.set("Double", Double.MIN_VALUE)
println("Double: ${kv.takeDouble("Double")}")
kv.set("String", "Hello from mmkv")
println("String: ${kv.takeString("String")}")
val bytes = byteArrayOf(
'm'.code.toByte(),
'm'.code.toByte(),
'k'.code.toByte(),
'v'.code.toByte(),
)
kv.set("ByteArray", bytes)
println("ByteArray: ${kv.takeByteArray("ByteArray")?.toString()}")
}
```
- **Deleting & Judging(Whether the key is exist):**
```kotlin
kv.removeValueForKey("Boolean")
println("Boolean: ${kv.takeBoolean("Boolean")}")
kv.removeValuesForKeys(listOf("Int", "Long"))
println("allKeys: ${kv.allKeys()}")
val hasBoolean = kv.containsKey("Boolean")
```
- If different modules/logics need **isolated storage**, you can also create your own MMKV instance separately:
```kotlin
import com.ctrip.flight.mmkv.mmkvWithID
...
val kvWithMyId = mmkvWithID("MyID")
kvWithMyId.set("Boolean", true)
```
- If **multi-process accessing** is needed, you can set `MMKVMode.MULTI_PROCESS` on MMKV initialization:
```kotlin
import com.ctrip.flight.mmkv.mmkvWithID
import com.ctrip.flight.mmkv.MMKVModel
...
val kvMultiProcess = mmkvWithID("InterProcessKV", MMKVModel.MULTI_PROCESS)
kvMultiProcess.set("Boolean", true)
```
## Supported Types
