pouchdb-adapter-asyncstorage

PouchDB adapter using AsyncStorage as its data store. Designed to run in ReactNative. Its adapter name is 'asyncstorage'.

Usage

npm install pouchdb-adapter-asyncstorage --save

import PouchDB from 'pouchdb-core'
PouchDB.plugin(require('pouchdb-adapter-asyncstorage').default)
const db = new PouchDB('mydb', {adapter: 'asyncstorage'})

// use PouchDB
db.get('4711')
  .then(doc => console.log(doc))

Memory

Be careful when using this with other AsyncStorage data or multiple databases as it loads all keys in your store into memory. You can use react-native-async-storage-rocks if this is an issue for you (see below).

Android limit

On Android asyncstorage has a limitation of 6 MB per default, you might want to increase it

// MainApplication.getPackages()
long size = 50L * 1024L * 1024L; // 50 MB
com.facebook.react.modules.storage.ReactDatabaseSupplier.getInstance(getApplicationContext()).setMaximumSize(size);

RocksDB

If you are using react-native-async-storage-rocks then pouchdb-adapter-asyncstorage will detect and use the native getKeysWithPrefix method for memory-efficient key lookups.
