Question

与PouchDB类似的东西会很棒。

当前键值存储（AsyncStorage）绝对不足以存储和查询数据。

Answer 1

我遇到了一些问题，让PouchDB处理react-native，但不想安装SQLLite。所以我构建了一个异步存储适配器。

它补充了React的缺失包+在＆＃34; asyncstorage-down＆＃34;上添加了一个异步存储适配器。适当的帮助。

Answer 2

我尝试过使用Stockulus＆＃39;异步存储适配器（https://github.com/stockulus/pouchdb-react-native）但在复制到远程CouchDB服务器时遇到问题。

现在我正在使用React原生SQLite存储（https://github.com/andpor/react-native-sqlite-storage）和PouchDB自定义构建模式（https://pouchdb.com/2016/06/06/introducing-pouchdb-custom-builds.html），如下所示：

'use strict';

import PouchDB from 'pouchdb-core'

// POLYFILLS - adapted from https://github.com/pouchdb/pouchdb/issues/3787#issuecomment-234618747
global.Buffer = global.Buffer || require('buffer').Buffer;
global.atob = global.atob || require('atob');
global.btoa = global.btoa || require('btoa');
require('blob-polyfill');

import SQLite from 'react-native-sqlite-storage';
global.openDatabase = SQLite.openDatabase; // Expose for websql adapter
GLOBAL.openDatabase = SQLite.openDatabase;

PouchDB
    .plugin(require('pouchdb-adapter-websql'))
    .plugin(require('pouchdb-adapter-http'))
    .plugin(require('pouchdb-replication'))

export default PouchDB

我知道全球是丑陋的。我们刚开始使用它，复制工作得更好。我们还必须填充一堆节点内容。这由pouchdb-core使用，但未在pouchdb-core中指定为依赖项。会喜欢反馈。

目前正在使用这些套餐：

"events": "^1.1.1",
"pouchdb-adapter-http": "6.0.6",
"pouchdb-adapter-websql": "6.0.6",
"pouchdb-core": "6.0.6",
"pouchdb-replication": "6.0.6",
"atob": "^2.0.3",
"blob-polyfill": "^1.0.20150320",
"btoa": "^1.1.2",
"buffer": "^5.0.0",

You can easily implement PouchDB on top on SQLLite - it has several configuration choices. You may need a SQLite Plugin to make it work. I have done this for Cordova in fact and it worked quite well. I believe PouchDB (which is pure JavaScript and therefore can be used out-of-the-box for ReactNative) has an adapter that works with the full featured SQLite3 Plugin.

React Native version of this plugin is available here:

https://github.com/andpor/react-native-sqlite-storage

The original Cordova plugin link can be found on the project github as well.

本机上是否存在任何文件存储？
