PouchDB fails to sync on iOS 9 - iPhone 5S

由 ε祈祈猫儿з 提交于 2020-01-04 07:11:33
问题 I am developing an app with IONIC and PouchDB. The app perfectly synchronizes with remote CouchDB and works perfectly well on Android. But the PouchDB fails to sync on iOS. I am testing on iOS 9 and iPhone 5S. What could be going wrong with the code in iOS ?? 回答1: Are you using WKWebView? PouchDB does not support WKWebView, unless you use the FruitDOWN adapter: http://pouchdb.com/adapters.html#pouchdb_in_the_browser 来源： https://stackoverflow.com/questions/35293323/pouchdb-fails-to-sync-on-ios

The _replicator database is not scalable or my design needs tweaking

问题 I think it is important that I elaborate on where I am coming from so that you can understand my use case, please bear with me. Background: I’m looking to migrate my app from CouchDB 1 to 2 and this migration is going to take a decent amount of work. I just want to double check that I’m not reinventing the wheel and make sure that there isn’t a better design to what I will elaborate on below, especially since CouchDB 2 appears to have some awesome new features. Consider the following

PouchDb Replicate of single document causes huge memory usage, then crash

由 烂漫一生 提交于 2020-01-03 05:07:24
问题 I have a situation where live sync is refusing to get some documents on it's own, making PouchDb.get return saying the document is not found (despite it being there in CouchDb that it is replicating from). Reading through the documentation, it suggests doing a manual replicate first, then a sync. So I changed my code to first replicate docId='testdoc'; return new Promise(function (resolve, reject) { var toReplicate=[docId]; console.log("replicate new ", toReplicate); var quickReplicate = self

Offline data with Cordova and PouchDB

由 孤者浪人 提交于 2020-01-03 04:42:50
问题 I am writing a dictionary app with Cordova. The data size is about 20MB. I want the app to work completely offline, and query data locally. And I find PouchDB really suitable for that. However, I also want to have all the data pre-installed with the app (in JSON format). That is, to put all the data in the app package (in www/data folder of the Cordova project). From what I've known so far, PouchDB can create data or sync data from a server, but I want to know how it can utilize data files

Can I create multiple collections per database?

由 老子叫甜甜 提交于 2019-12-30 02:09:10
问题 Switching from mongo to pouchdb (with Cloudant), i like the "one database per user" concept, but is there a way to create multiple collections/tables per database ? Example - Peter - History - Settings - Friends - John - History - Settings - Friends etc... 回答1: Couchdb does not have the concept of collections. However, you can achieve similar results using type identifiers on your documents in conjunction with Couchdb views. Type Identifiers When you save a document in Couchdb add a field

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 一、cookie 1.使用限制 根据统计表明，每个域名50个、大小总计4KB的Cookie是安全的，更多的cookie使用需要进行评估。 2.通常的用法如： 1)写入cookie document.cookie = "name=value"; 指定过期时间和可以访问的域名 document.cookie = "name=Raymond; expires=Fri, 31 Dec 9999 23:59:59 GMT;domain=app.foo.com"; document.cookie = "age=43"; 2)读取cookie document.cookie "name=value;age=43" 得到以分号分隔的字符串 二、web存储API 1.使用限制 1)Web存储有两个版本：本地存储（Local Storage）和会话存储（Session Storage）。两者使 用完全相同的API，但本地存储会持久存在（或者直到用户清除），而会话存储只要浏览器 关闭就会消失。Web存储API官方规范的网址为 http://www.w3.org/TR/webstorage。 2)Web存储是与域名一一对应的。和Cookie不同的是，无法让app.foo.com使用www.foo.com存储的数据。

Promise with Pouch not returning from call to inside code

由 爷，独闯天下 提交于 2019-12-25 16:17:26
问题 I have a promise that seemed to work before but not now. I think I have everything in place but after the .get is called, it never gets to the for loop. It jumps to the end and out of the promise, then back to the return (inside the .get) then to the resolve and then out. If there were an error, it should have jumped to the catch but didn't, so how does it miss the for loop? Here is the code: function readAllImagesFromPouch(id, imageDisplay) { return new Promise(function (resolve, reject) {

Is it possible to get the latest seq number of PouchDB?

由 血红的双手。 提交于 2019-12-25 00:43:15
问题 I am trying to cover for an issue where CouchDB is rolled back, causing PouchDB to be in the future. I want to find a way to detect this situation and force PouchDB to destroy and reload when this happens. Is there a way to ask PouchDB for it's current pull seq number? I am not able to find any documentation at all on this. My google-foo is not strong enough. So far my only thought is to watch the sync.on(change) feed, and record the seq number on every pull. Then on app reload, run this as
