ionic framework sync data and work offline

由 流过昼夜 提交于 2019-12-02 21:18:14
I'm developing an app using ionic framework, and it will fetch some data from an API which was built using laravel, save it in a database so when the user is offline he can continue use the app, I did a little research on the internet and found a plugin called pouchDB, is it recommended for what I need? what is the best way to do it?

How to manage pouchdb and couchdb synchronization?

Best approach to store multiple user data is per user per database. I am using this same approach. I have couchdb on server and pouchdb for mobile application. I am maintaining each user data by creating separate database for the user in pouchdb and couchdb. That.That means i have multiple database in couchdb and one database in pouchdb. usually in sqlbase database user data is store in different different table. so in nosql pouchdb i am creating document for each table. Actual problem i am facing is: I have one document in each database that stores the transactions of user. Client transaction

In a Phonegap offline/online project: What is the difference between using PouchDB and using CouchBase Lite with the new LiteGap plugin? Are they two different solutions to the same problem? Can the PouchDB API be used to interact with a local CouchBase Lite database? After some research and being a relatively new topic, i thought it would be interesting to share my experiences replying my own question: What is the difference between using PouchDB and using CouchBase Lite with the new LiteGap plugin? PouchDB can create a local database ( websql or IndexedDB ) on the device and replicate it

How can I clear this cache and get back to my original testing enviornment? 回答1: It took me days to figure this out so I figured I'd post it here, just rm -rf ~/Library/Application\ Support/Ofi\ Labs/PhantomJS/* I hope this saves someone else the hassle! 来源： https://stackoverflow.com/questions/25578054/how-do-i-clear-the-phantomjs-cache-on-a-mac

Is there a way to get all revisions of a document in PouchDB when using the change feed?

由 廉价感情. 提交于 2019-12-01 12:55:02
I'm fiddling around with PouchDB at the moment. I use it as a way to store data locally without it being linked to CouchDB. What I've been trying to do is to create a revert/undo method for a single doc. For this I would like to use the previous revisions of the "doc". I came across the changes feed while reading the PouchDB documentation, which at first seems to be a way to get all the revisions of the all the "docs". However, after trying to get all the revisions of the "docs" I've only got the latest revision. I've tried the following to get the changes: db.changes({ since: 0, style: 'all

问题 I have a really simple question about hard topic: How does conflict resolution work in PouchDB? I looked at the documentation, as well as quickly googling, but it didn't help. So, how to do I handle conflict management in my application which is using PouchDB? 回答1: Here's how you do it in CouchDB, which you can directly translate into PouchDB terms since the APIs are exactly the same. You fetch a document, using conflicts=true to ask for conflicts ( get() with {conflicts:true} in PouchDB):
