Is there already a Redis data access framework for Dart? - redis

Question

My server-side code runs on Dart and currently uses Redis as a data store via redis_client.
Mostly, I'm persisting primitive data types such as integers and strings. However, I also have a handful of business objects like User, and ideally I'd like to store those in Redis as well.
Of course, Redis is a key-value store and not a full-fledged document database like MongoDB. So I started writing my own serialization and persistence logic - for example, a simple getter for User:
import 'dart:convert';
...
Future<User> GetUser(String userGuid)
{
var userKey = "userGuid:" + userGuid.toString();
return redisClient.get(userKey).then((String value) {
return new User.fromJSON(value);
});
}
Before I continue hand-crafting the entire persistence logic for all my business entities - is there already some sort of Redis/Dart data access package out there I should be aware of, similar to e.g. redis_orm (Ruby)?
If not, I'll probably write my own.
(Don't wanna call it ORM because, well, Redis != relational - but effectively that's what I'm looking for)

We're using Java Hibernate + Dart at work,
I made an open source library for the client for this : https://github.com/frankpepermans/dorm
The server-side implementation is not open source however, Hibernate is not a requirement and any ORM type would do, the client communicates via JSON, so you'll need an adapter that works with JSON data and can handle/receive cyclic references (via Dorm, you can use pointers inside the JSON structure to specify a cyclic reference).
The server would also need to generate Dart class files that represent the entities.
But you can have for example :
- composite keys
- entity inheritance
- custom handling of data types (i.e. DateTime)
- custom data types (i.e. everything is Observable, lists are ObservableList by default, but you can tell the deserializer to use a custom List type if needed)
- supports annotations
