# fdp-lokijs-adapter

FDP LokiJS DB Adapter, experimental database adapter on top of `fdp-storage` and compatible with `rxdb`

## Usage

```typescript

import { BatchId } from '@ethersphere/bee-js'

import { BeeSon, Type } from '@fairdatasociety/beeson'

import * as Block from 'multiformats/block'

import { FdpStorage } from '@fairdatasociety/fdp-storage'

import { LokiFDPAdapter } from '@fairdatasociety/fdp-lokijs-adapter'

import { LokiPartitioningAdapter } from 'lokijs'

import loki from 'lokijs'

const id = `54ed0da82eb85ab72f9b8c37fdff0013ac5ba0bf96ead71d4a51313ed831b9e5` as BatchId

const client = new FdpStorage('http://localhost:1633', id)

// TODO: Be sure to login first with your account or Blossom wallet

// Instantiate LokiFDPAdapter

// WIP is using streaming feeds

const lokifdp = new LokiFDPAdapter(client, 'swarmbee', {

    init: new Date().getTime(),

    updateInterval: 1000,

})

// autosave interval matches LokiFDPAdapter updateInterval

const pa = new LokiPartitioningAdapter(lokifdp, { paging: true })

const db = new loki('swarm.db', { adapter: pa, autosave: true, autosaveInterval: 1000 })

// Create and work with Loki DB

const users = await db.addCollection('users')

const odin = users.insert({

    name: 'Odin',

    age: 50,

    address: 'Asgard',

})

// alternatively, insert array of documents

users.insert([

    { name: 'Thor', age: 35 },

    { name: 'Loki', age: 30 },

])

const results = users.find({ age: { $gte: 35 } })

// returns 2 users

// Update

odin.age = 60

users.update(odin)

const results2 = users.find({ age: { $gte: 59 } })

// returns 1 user

```
