`blini` is a modern ORM for **MongoDB** based on [immutable](https://facebook.github.io/immutable-js/) data structure and promises.

**Blini is currently in alpha.** API may changed, don't use it for production applications.

## Example

```js
import { Schema, Type, Model, Connection } from 'blini'
const connection = new Connection('mongodb://localhost/test')

const postSchema = new Schema({
    title: Type.String(),
    views: Type.Set(Type.String)
})

class Post extends Model(postSchema, connection, 'Cat') {
    get summary() {
        return `Post ${this.title},  ${this.likes.size} readers`
    }

addView(ip) {
        const { views } = this;
        return this.merge({
            views: views.add(ip)
        })
    }
}

const post = new Post({ title: 'My Super blog post' })

post.addView('127.0.0.1').save()
    .then(function(savedPost) {
        console.log(savedPost.summary)
    })
```

## Principles

First of all, this library is a Work-In-Progress and Proof-Of-Concept.

Before creating Blini, I've used a lot [Mongoose](http://mongoosejs.com) for production applications, Blini borrowed a few concepts from it (Checkout the full list of [differences](docs/from-mongoose.md)).

But it differs on a few core principles:

1. **Immutable data:** By using Immutable.js, the Blini is built in a stateless fashion using immutable data structures, which leads to much easier to reason about code, and a much easier time working with data sets.

2. **Simplicity:** Blini tries to reduce the number of concepts and provide a unified API (it doesn't support callback, etc).

3. **Composition:** Instead of relying on a custom plugins logic to handle extensibility,
it uses ES6 classes inheritances and compositions to extend models behavior.

4. **Intuitive Data Structure:** By using Immutable.js iterable data structure (`List`, `Map` and `Set`), it makes easier to manipulate document.

## Documentation

If you're using Blini for the first time, check out the [Getting Started](docs/getting-started.md) guides and the Core Concepts to familiarize yourself with Blini's architecture and mental models. Once you've gotten familiar with those, you'll probably want to check out the full API Reference.
