## Install

Install from the NPM repository using yarn or npm:

```shell
yarn add normalizr
```

```shell
npm install normalizr
```

## Motivation

Many APIs, public or not, return JSON data that has deeply nested objects. Using data in this kind of structure is often very difficult for JavaScript applications, especially those using [Flux](http://facebook.github.io/flux/) or [Redux](http://redux.js.org/).

## Solution

Normalizr is a small, but powerful utility for taking JSON with a schema definition and returning nested entities with their IDs, gathered in dictionaries.

## Quick Start

Consider a typical blog post. The API response for a single post might look something like this:

```json
{
  "id": "123",
  "author": {
    "id": "1",
    "name": "Paul"
  },
  "title": "My awesome blog post",
  "comments": [
    {
      "id": "324",
      "commenter": {
        "id": "2",
        "name": "Nicole"
      }
    }
  ]
}
```

We have two nested entity types within our `article`: `users` and `comments`. Using various `schema`, we can normalize all three entity types down:

```js
import { normalize, schema } from 'normalizr';

// Define a users schema
const user = new schema.Entity('users');

// Define your comments schema
const comment = new schema.Entity('comments', {
  commenter: user
});

// Define your article
const article = new schema.Entity('articles', {
  author: user,
  comments: [comment]
});

const normalizedData = normalize(originalData, article);
```

Now, `normalizedData` will be:

```js
{
  result: "123",
  entities: {
    "articles": {
      "123": {
        id: "123",
        author: "1",
        title: "My awesome blog post",
        comments: [ "324" ]
      }
    },
    "users": {
      "1": { "id": "1", "name": "Paul" },
      "2": { "id": "2", "name": "Nicole" }
    },
    "comments": {
      "324": { id: "324", "commenter": "2" }
    }
  }
}
```

## Dependencies

None.
