## A Kotlin toolkit for Mongo
Documentation: [https://litote.org/kmongo](https://litote.org/kmongo)
Forum: [https://groups.google.com/forum/#!forum/kmongo](https://groups.google.com/forum/#!forum/kmongo)
### Native and Lightweight
KMongo features are available via [Kotlin extensions](https://kotlinlang.org/docs/reference/extensions.html) -
you use transparently [the core MongoDB java driver API](https://www.mongodb.com/docs/drivers/java-drivers/)
(both sync and reactive streams (ie async) drivers are supported)
#### With complete reactive streams & async support
You can use extensions for reactive streams style, [Kotlin Coroutines](https://kotlinlang.org/docs/reference/coroutines.html),
[Reactor](https://projectreactor.io/) or [RxJava2](http://reactivex.io/).
### Built-in Object Mapping
Object oriented programming is usually better - use Objects, not Maps. Powered by the native
[POJO Codec](https://mongodb.github.io/mongo-java-driver/3.5/bson/pojos/), the
[Jackson library](https://github.com/FasterXML/jackson) or
[Kotlinx Serialization](https://github.com/Kotlin/kotlinx.serialization).
### Type-safe queries
Have you already queried an ```Int``` field with a ```String``` value?
With KMongo type-safe queries, avoid the type errors.
Provided with an optional annotation processor.
### Mongo shell queries
You can copy/paste your queries from the Mongo shell in your IDE. Write readable source code!
