kandi X-RAY | couchbase-promises Summary
Just like the Couchbase Node.js SDK, but with the addition of *Async() methods that return A+ Promises for all methods that contain a Node.js callback parameter. This module functions as a drop-in replacement for the couchbase module. Additionally, this library provides enhanced support for bulk operations. The the native couchbase module only provides batch operation support for key lookups (via Bucket.prototype.getMulti()). The couchbase-promises module provides a extra methods on the Bucket class for performing batch operations. See the API documentation for more information. The current version supports Couchbase Node.js SDK version 2.3.0.

QUESTION
I'm using the Couchbase nodeJS SDK. To make a query I must call bucket.query("SELECT ...", function(err, rows){console.log("query's result received")})
I would like to run queries sequentially like :
- Run query A
- Work on result A
- Run query B
- Work on result B
- ...
- Continue after all results has been reveived and handle
Or even better it could be
- Run all queries
- Work on results one by one as they are being reveived
- Continue after all results has been reveived and handle
The point is I dont know how to wait for all the queries to be finished before continuing. I tought of promises but I'm new to nodeJS and I'm not sure I used them correctly, maybe someone could point me to the right direction ?
I saw that the async/await feature is available in node but I didn't manage to make it working either.
Any help would be apprecietate !

I tried to use couchbase-promises but I still don't get the behavior I expect. Here is what I've done:
