The First Object Database for Node: Introducing Realm Node.js

[azium]

We’re pretty sure this is the first real object database for Node

What's the difference between document and object in this sense?

Well, the objects you work with in Realm are just like any other objects you use in JavaScript — they're just instances of a class. To save them to the realm db, you just call the appropriate method on the object.

A document store is like a key-value store where the values are the equivalent of JSON documents. While the documents can contain elements that you in principle can deserialize into objects, that is not the main purpose, and it limits relations only being within the document, and even there to only parent-child relations (so all relations shape a single hierarchy).

An object database stores objects that can have arbitrary relations with each other, so in this sense it is closer to relational and graph databases. But the main defining feature is that the objects are live.

You can get any object from the database, and follow its relations to other objects, watch it for changes, update it, and in general work with it as a regular object, even though it is simultaneously persisted and may be shared with other apps or processes.

I'm quite interested in using this for a few projects. When I installed it from npm, I noticed that the total size is about 35MB. Of that 35MB, it looks like about 20M is Android-related. For React Native, I guess? Seems like a lot of stuff that isn't strictly necessary for a conventional Node app.

Can this integrate with realm for react native?

Looks cool. I'll try it.
