Support for stitch apps

[robert-cronin]

This might be completely out of left field, but is there any way to use KMongo to connect to MongoDB via stitch API? There is a JavaScript stitch API and a Java API for Android but nothing for pure Kotlin or Java desktop apps.

The reason behind wanting this is that stitch allows rules for which data to serve in a collection based on specific user data like a owner_id for example. It might be possible with a Kotlin wrapped over the stitch JavaScript API but I thought I might ask if its in the plan for KMongo first.

There is no support planned for now. However I think it should be doable using https://github.com/mongodb/stitch-android-sdk (it seems that there is also a "pure java" version you can use in this sdk - org.mongodb:stitch-server-sdk:version)

val conf = StitchAppClientConfiguration.Builder().run {
  //with this line you should enable the KMongo object mapping support -> 
  withCodecRegistry( ClassMappingType.codecRegistry(BsonUtils.DEFAULT_CODEC_REGISTRY))
  build()
}
val client = Stitch.initializeAppClient("<clientId>",conf)

Of course there is no extension defined for RemoteMongoCollection but you can add them using KMongo source code... ;)

What sort of things would need to be implemented to make the package usable? Could I follow the async or coroutines code to get an idea for what to make? I guess I need a bit of guidance on this matter

I would follow these steps:

1. Add these dependencies org.mongodb:stitch-server-sdk:4.2.1 org.litote.kmongo:kmongo:3.10.0

2. Use the code in the previous comment to insert and retrieve simple data with RemoteDataCollection using this doc: https://docs.mongodb.com/stitch/mongodb/mobile/build-sync/ . This should work (but I have not tested).

3. You can add extensions on the Sync interface ( mongodb.com/stitch-sdks/java/4/com/mongodb/stitch/android/services/mongodb/remote/Sync.html ) as it is done in KMongo: https://github.com/Litote/kmongo/blob/master/kmongo-core/src/main/kotlin/org/litote/kmongo/MongoCollections.kt .
