A performant fork of PouchDB for React Native.

NOTE: The attachment support has been dropped since I no longer store binary data in PouchDB.

1. Install dev package:

   yarn add -D babel-plugin-module-resolver
   

2. Install polyfill packages:

   yarn add events react-native-get-random-values react-native-quick-base64

3. Install pouchdb packages:

   yarn add pouchdb-core pouchdb-replication pouchdb-mapreduce pouchdb-adapter-http

4. Install patched package:

   yarn add @craftzdog/pouchdb-collate-react-native

   It avoids using '\u0000' chars for indexing (See this commit).

5. Install storage adapter packages:

   yarn add pouchdb-adapter-react-native-sqlite react-native-quick-sqlite react-native-quick-websql

   • react-native-quick-sqlite - A fast bindings via JSI for SQLite
   • react-native-quick-websql - WebSQL wrapper for quick-sqlite
   • pouchdb-adapter-react-native-sqlite - PouchDB adapter for SQLite with those two modules

6. Install CocoaPods:

   npx pod-install

1. Make a shim.js:

   import {shim} from 'react-native-quick-base64'
   
   shim()
   
   // Avoid using node dependent modules
   process.browser = true

   then, require it at the beginning of your index.js.

2. Edit your babel.config.js like so:

   module.exports = {
     presets: ['module:metro-react-native-babel-preset'],
     plugins: [
       [
         'module-resolver',
         {
           alias: {
             'pouchdb-collate': '@craftzdog/pouchdb-collate-react-native',
           },
         },
       ],
     ],
   }
   

Create pouchdb.ts like so:

import 'react-native-get-random-values'
import PouchDB from 'pouchdb-core'
import HttpPouch from 'pouchdb-adapter-http'
import replication from 'pouchdb-replication'
import mapreduce from 'pouchdb-mapreduce'
import SQLiteAdapterFactory from 'pouchdb-adapter-react-native-sqlite'
import WebSQLite from 'react-native-quick-websql'

const SQLiteAdapter = SQLiteAdapterFactory(WebSQLite)

export default PouchDB.plugin(HttpPouch)
  .plugin(replication)
  .plugin(mapreduce)
  .plugin(SQLiteAdapter)

Then, import and use it as usual:

import PouchDB from './pouchdb'

const db = new PouchDB('mydb.db', {
  adapter: 'react-native-sqlite'
})

We're always looking for new contributors! If you'd like to try your hand at writing code, writing documentation, designing the website, writing a blog post, or answering questions on StackOverflow, then we'd love to have your input.

If you have a pull request that you'd like to submit, please read the contributing guide for info on style, commit message format, and other (slightly!) nitpicky things like that. PouchDB is heavily tested, so you'll also want to check out the testing guide.
