pouchdb

问题 I am currently using PouchDB and I am making use of Cloudant to make my db in PouchDB to be on cloud. I did callback method and it gave a success callback, however, I check my database on Cloudant, there's 0 doc created but there's 8 update seq. May I know why? This is my set of code I used. function pouchdb() { var db = new PouchDB("todos"); var remoteDB = new PouchDB("http://example.cloudant.com/example"); var todo = { _id: "mittens1233", title: "hello", occupation: "kitten123" }; db.put

问题 The PouchDB Manual suggests using Date().toJSON() to generate a new id for each document. Do all javascript runtimes guarantee that Date().toJSON() will always be unique? 回答1: The dates only have microsecond precision, so there's no guarantee they will be unique. The snippet below will give you a number of duplicates in all but the slowest runtime environments: for (let i = 0; i < 10; i++) { console.log(new Date().toJSON()) } 回答2: In case of distributed system, We can also use this eventid

问题 What is the recommended way of dealing with multiple PouchDB instances in the browser that synchronize simultaneously with the same remote/local database? 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. In such a case, only one PouchDB instance will report remote changes - other instances produce a conflict during

问题 Can anyone provide me a simple example how to implement the "Database per user pattern" in CouchDB (Cloudant <-> PouchDB)? The users get authenticated with Auth0 (jwt). I'm not able to find something regarding this topic. Any help would be appreciated! 回答1: here is a sample register/sign-up application using the "one database per user" pattern. you can review it's approach to help you get started. however, you may want to consider cloudant-envoy which allows your client side code can adopt a

问题 I would like to search trough an array of objects (that are encapsulated in one big object), and emit only the one of the internal objects. So let's suppose I have a JSON inserted into PouchDB that is looks like this: { "_id": "5eaa6d20-2019-44e9-8aba-88cfaf8e02542", "data": [ { "id": 1452, "language": "java" }, { "id": 18787453, "language": "javascript" }, { "id": 145389721, "language": "perl" } ] } How to get PouchDB to return the following result when searching for a language with an id =

问题 Very similar to these two CouchDB questions: 3311225 and 8924793, except that these approaches don't allow partial matching . Having e.g. these entries: [{_id: 1, status: 'NEW', name: 'a'}, {_id: 2, status: 'NEW', name: 'aab'}, {_id: 3, status: 'NEW', name: 'ab'}, {_id: 4, status: 'NEW', name: 'aaa'}, {_id: 5, status: 'NEW', name: 'aa'}] and key [status, name, _id] There seems to be no way to filter these entries by status (full string match) and name (partial string match ~ startsWith )

问题 I wish to use PouchDB - CouchDB for saving user data for my web application, but cannot find a way to control the access per user basis. My DB would simply consists of documents using user id as the key. I know there are some solutions: One database per user - however it requires to monitor whenever a new user wants to save data in order to create a new DB, and may create a lot of DBs; Proxy between client and CouchDB - however I don't want PouchDB to sync changes for the whole DB including

问题 I have the following use case / application: a TODO app where users can: CRUD their on TODOs (I am using pouchdb/couchdb syncing). Pretty much based on Josh Morony's tutorial Now I want to add ability of users to "share" (post only, there is no "edit"/put) their TODO items with other users, who would be able to just view (read) those (no write access etc). I was thinking about adding a separate DB (let's call it "shared TODOs DB") where my server can write and all users can only read. So any

问题 I need to sync server data from CouchDB and PouchDB on client side. Every user has his own data. When he is online this data is being updated. How can I filter data during replication and give user only his own documents? This is security issue for me. 回答1: Currently the best practice for doing private user data in PouchDB/CouchDB is to give each user their own database on the server side. I have some instructions here for how to do this. 回答2: Having a separate DB for each user is fine until

问题 I'm new to PouchDB, currently try to use Pouchdb on my Phonegap android app. I'm using Todos Sample App from http://pouchdb.com/getting-started.html. It worked fine on browser, but not on Android (Jelly Bean 4.2), I'm using HTC One Mini to test the app. Here is my code : <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <title>VanillaJS TodoMVC</title> <link rel="stylesheet" href="style/base.css"> <!--[if IE]> <script
