如何处理浏览器中与同一个数据库同步的多个PouchDB实例？ [英] How to handle multiple PouchDB instances in the browser that sync with the same db?

问题描述

在浏览器中处理与同一个远程/本地数据库同时同步的多个PouchDB实例的推荐方法是什么？

What is the recommended way of dealing with multiple PouchDB instances in the browser that synchronize simultaneously with the same remote/local database?

我的设置是一个Web应用程序与远程CouchDB连续同步的浏览器。
可以多次打开该Web应用程序（多个选项卡/窗口），从而创建多个尝试同步的PouchDB实例。

My setup is a web application in the browser that synchronizes continuously with a remote CouchDB. That web app could be opened more than once (multiple tabs/windows) and thus create multiple PouchDB instances that try to sync.

在这种情况下，只有一个PouchDB实例将报告远程更改-其他实例在实时同步期间产生冲突：

In such a case, only one PouchDB instance will report remote changes - other instances produce a conflict during live sync:

{
  error: true,
  message: "Document update conflict",
  name: "conflict",
  result: {
    doc_write_failures: 0,
    docs_read: 1,
    docs_written: 1,
    end_time: ...,
    errors: [
      CustomPouchError
    ],
    last_seq: 963,
    ok: false,
    start_time: ...,
    status: "aborting"
  },
  status: 409
}

我是否需要确保一次仅同步一个PouchDB实例并手动传递更改？

Do I need to ensure that only one PouchDB instance syncs at a time and pass changes around manually?

推荐答案

PouchDB复制当前无法在多个选项卡中使用。这是一个未解决的问题，任何想加入的人都将非常欢迎。 ：）

PouchDB replication currently does not work in multiple tabs. It is an open issue, and anybody who wants to hop in would be more than welcome to. :)
