# About

<!--

-->

A Datastore implementation that uses a flavour of [Level](https://leveljs.org/) as a backend.

This module is targetted at Node.js. It is possible to use it in a browser but you should probably use IDBDatastore instead.

## Example

```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-'
  })
})
```

# Install

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

## Browser `<script>` tag

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

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