Install

$ npm i datastore-level

Usage

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.

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