self.couchServer.allDatabases

(which will work in CouchCocoa/TouchDB as well. There’s no need to manually load _all_dbs.)

And Since there is no server involved in CBL, How do you suggest me to upgrade from CouchServer, which is used as a connection manager? 

CBLManager is the equivalent of CouchServer.

Thank you Jens!

Hello,

     Continuing on same topic of transition to CBL, I've one more question.

  Actually, I'm trying to upgrade an app which uses TouchDB version 0.9 and in this app, It collects deviceID and creates a new configuration database(if needed) on server (something like this "config_deviceID"). Later this configuration database link is returned (URL/config_deviceID). So basically, a database is created on the server for very iPad device.  Here are the codes:

   RESTResource* resource = [[RESTResource alloc] initWithURL:[NSURL URLWithString:URL]];

    

    // prepare data to be posted to the server

    NSMutableDictionary *postData = [[NSMutableDictionary alloc] init];

    [postData setValue:"deviceID" forKey:@"deviceid"];

    [postData setValue:"email" forKey:@"email"];

    

    RESTOperation* op = [resource POSTJSON:postData parameters:nil];

  

    if ([[op start] wait]) {

        NSDictionary* response = op.responseBody.fromJSON;

          }

How can I talk to server with Couchbase-lite ? Please suggest me a solution.

To talk to a remote CouchDB-compatible server, you’ll need to use CouchCocoa. (Yes, it’s fine to include both Couchbase Lite and CouchCocoa in your app. You’ll just need to use different APIs to talk to your local database vs. remote databases.)

Well, I'll use CouchCocoa. But then how do you suggest me to handle replication? I need to establish a persistent replication between Couchbase Lite and Remote CouchDB.

Secondly, Remote CouchDB's view has "design document name and view name"(Eg: designDocName001/viewName, designDocName002/viewName) and Couchbase-Lite has "no design document name". So, after replicating remote database to local, how can I access/write design documents/CBLViews ?

Couchbase Lite does replication. That’s its most important feature, after all. See the docs.

In both Couchbase Lite and TouchDB you define views as Objective-C blocks, not as JavaScript functions. This is because iOS doesn’t have a publicly available JavaScript interpreter, and Apple’s guidelines forbid you from executing downloaded code. (It’s also faster.) See the docs.

That sounds pretty close to what I'm doing as well. Look forward to sharing lessons learned.

Ah! I'm very clear. Please excuse me for silly questions and thanks a lot for your great support, Jens.
