## Install

```console
$ npm i datastore-level
```

### Browser `<script>` tag

Loading this module through a script tag will make it's exports available as `DatastoreLevel` in the global namespace.

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

## Usage

```js
import { LevelDatastore } from 'datastore-level'

// Default using level as backend for node or the browser
const store = new LevelDatastore('path/to/store')

// another leveldown compliant backend like memory-level
const memStore = new LevelDatastore(
new MemoryLevel({
keyEncoding: 'utf8',
valueEncoding: 'view'
})
)
```

### Browser Shimming Leveldown

`LevelStore` uses the `level` module to automatically use `level` if a modern bundler is used which can detect bundle targets based on the `pkg.browser` property in your `package.json`.

If you are using a bundler that does not support `pkg.browser`, you will need to handle the shimming yourself, as was the case with versions of `LevelStore` 0.7.0 and earlier.

### Database names

`level-js@3` changed the database prefix from `IDBWrapper-` to `level-js-`, so please specify the old prefix if you wish to continue using databases created using `datastore-level` prior to `v0.12.0`. E.g.

```javascript
import leveljs from 'level-js'
import browserStore = new LevelDatastore(
new Level('my/db/name', {
prefix: 'IDBWrapper-'
})
})
```
