Kefei
Is it just me or are databases a bit of a ballache ?!?!
Kefei is a simple and easy alternative…
class MyClass: Persistable() {
@Persist
lateinit var myImportantList: MutableList<String>
@Persist
lateinit var myImportantStr: String
/* Whatever else you want... */
}
Stack:
- Kotlin
- Gradle
- Dependencies
- Kotlin test
- Kotlin test junit
- Logback
- Moshi (for serialisation of objects and properties)
- Kotlin reflect
How it works:
In essence, for any class that extends persist.Persistable that has properties annotated with @persist.Persist, kefei will register a jvm shutdown hook to save the value of the property to a local file under the path ./${options.dir}/${class.name}/${field.class.name}/${field.name}
Then, when the application restarts, the same properties from the same class will load its initial value from the file with this path.
Features
- Supports all primitives and data types (AFAIK)
- JSON serialisation using Moshi
- Optional configuration file
- Minimal, simple code and easy to integrate into projects
- Occasionally dips into the JVM for reflection, but as much as possible is done at the kotlin layer
- Logging of all major lifecycle events use kotlin-logging and logback
