autorev

Blindly update couchdb documents by pulling down the latest _rev and bolting it to the document. This is useful for synchronizing design documents where source control holds the definitive copy.

examples

command-line

record.js

{
    _id : '_design/record',
    views : {
        all : function (doc) {
            if (doc.type === 'record') emit(null, doc)
        },
        by_experiment : function (doc) {
            if (doc.type === 'record') emit(doc.experiment, doc)
        },
        by_session : function (doc) {
            if (doc.type === 'record') emit(doc.session, doc)
        }
    }
}

output

$ autorev http://localhost:5984/experiments record.js
{"ok":true,"id":"_design/record","rev":"1-36194dcb0ade1549f4aed8c261b2c5f6"}
$ autorev http://localhost:5984/experiments record.js 
# not updated

programatically

var autorev = require('autorev');
autorev('http://localhost:5984/experiments', {
    _id : '_design/record',
    views : {
        all : function (doc) {
            if (doc.type === 'record') emit(null, doc)
        },
        by_experiment : function (doc) {
            if (doc.type === 'record') emit(doc.experiment, doc)
        },
        by_session : function (doc) {
            if (doc.type === 'record') emit(doc.session, doc)
        }
    }
}).pipe(process.stdout);

methods

var autorev = require('autorev')

autorev(uri, doc)

Update the document in the database at uri with doc. doc should have an _id field at the very least. The _rev field will be fetched from the latest revision and used to blindly update the document.

Return a stream with the server response or "# not updated\n" if the document didn't change.
