问题 I'm using CouchDB 2.1.0 on my localhost to sync the data from a web app. Everything was working until I add a new regular user through the PouchDB API and sync the remote database (localhost) with the local one (browser storage). After that, I couldn't access the remote _users database and one of the databases couldn't load even in the list of all databases. I try to refresh Fauxton and, then, it was unreachable. I tried restarting CouchDB in the terminal and I got no feedback for that. When

问题 I'm using a design document to ensure that only owners can modify docs. How can I prevent couchdb from replicating this design document? 回答1: You can use the filter option in changes() and replicate() , e.g. var opts = { live: true, filter: function(doc) { return doc._id.indexOf('_design') !== 0; } }; var db = new PouchDB('todos'); db.replicate.to('http://localhost:5984/todos', opts); 来源： https://stackoverflow.com/questions/26394999/filter-design-documents-with-pouchdb

问题 This leaflet example (Leaflet.TileLayer.PouchDBCached) is using an "idb" adapter and for electron/node it looks like I want to use a "leveldb" adapter.

By default, if you create a PouchDB like this one: var pouch = new PouchDB('./path/to/db'); then a LevelDB-based database will be created in the directory ./path/to/db. The LevelDB implementation uses LevelDOWN. In my

问题 I am developing an Ionic App using PouchDb (No replication). I am able to store data with attachments successfully.

问题 I have a news base that needs to work online and offline. I'm using CouchDB (IBM Cloudant ) and PouchDB to make this sync with the APP. The problem is that the news is relatively "heavy" for having photos and am having sync problems because the size of the "docs", and does not see any need to synchronize all the news base, will only fill the user's mobile phone with unnecessary records. I need to sync only some news, approx. five registers. I wonder how can I do this in CouchDB or PouchDB. I

问题 I come from a Mysql background and I'm using Pouchdb now. I'm used to the SQL pattern of having 1 database and many tables per app. In pouchDB it's different, because data is not stored in tables but in documents. So, in my app, I have a database for tasks, created with: var db = new PouchDB('tasks', {revs_limit: 1, auto_compaction: true}); This is the main database for my application, but now I need to also store settings, such as "last_visit_date", "language_preference" and others. So, I
