Various Datastore implementations are available.

## BaseDatastore

An base store is made available to make implementing your own datastore easier.

## Example

```javascript
import { BaseDatastore } from 'datastore-core'

class MyDatastore extends BaseDatastore {
  constructor () {
    super()
  }

  async put (key, val) {
    // your implementation here
  }

  async get (key) {
    // your implementation here
  }

  // etc...
}
```

See the [MemoryDatastore](https://github.com/ipfs/js-stores/blob/main/packages/datastore-core/src/memory.ts) for an example of how it is used.

## Wrapping Stores

## Example

```js
import { Key } from 'interface-datastore'
import {
  MemoryStore,
  MountStore
} from 'datastore-core'

const store = new MountStore({prefix: new Key('/a'), datastore: new MemoryStore()})
```

## BlackHoleDatastore

## Example

A datastore that does not store any data.

```js
import { BlackHoleDatastore } from 'datastore-core'

const store = new BlackHoleDatastore()
```

# Install

```console
$ npm i datastore-core
```

## Browser `<script>` tag

Loading this module through a script tag will make its exports available as `DatastoreCore` in the global namespace.

```html
<script src="https://unpkg.com/datastore-core/dist/index.min.js"></script>
```
