Transformware that maintains consistent object identity when using a
[sticky](https://github.com/bvalosek/sticky) datastore.

## Installation

```
$ npm install sticky-identity
```

## Usage

Assuming we have a [sticky](https://github.com/bvalosek/sticky) `Datastore` as
`db` and some sourced repository for the `User` model:

```javascript
var identity = require('sticky-identity');

db.use(User, identity());
```

Model identity is consistent now across all calls.

```javascript
var user = new User();
user.email = 'awesome@cool.net';
db.add(User)(user)
  .then(function(u) {
    u === user; // true
    return db.get(User)(user.id);
  })
  .then(function(u) {
    u === user; // true
  });
```

Identity is checked via the `id` parameter by default, but can be determined by
any string-like return value from a function argument:

```javascript
db.user(User, identity(function(x) { return x._id; }));
```

Keep in mind that the memory usage of this transformware will scale as the
number ofunique objects that are output or input into the repository grows.

## Testing

```
$ npm test
```
