A simple vows based wrapper for jquery.couch.js.
Works both in the browser and on nodejs.
In the browser copy the following files from the lib directory to your script directory, and add the appropriate script tags to your html file:
jquery.js
vow.js
jquery.couch.js
couchapi.js
You will have a global named couchapi (and VOW as well);
On nodejs
npm install couchapi
or npm install git://github.com/michieljoris/couchapi.git
will fetch the nodejs versions of jquery and vow. The module can be required with:
var couchapi = require('couchapi);
The promises implementation is the one from Douglas Crockford. Simple and sufficient.
It is mirroring almost all functionality of the jquery javascript adapter that comes with futon, but the functions are returning vows instead of expecting success and error callbacks passed in.
I added a few more utility functions mainly to easily configure and modify security objects and design documents.
One addition is an implementation of
1. GET docid?conflicts=true
2. For each member in the _conflicts array:
GET docid?rev=xxx
If any errors occur at this stage, restart from step 1.
(There could be a race where someone else has already resolved this
conflict and deleted that rev)
3. Perform application-specific merging
4. Write _bulk_docs with an update to the first rev and deletes of
the other revs.
as described in http://wiki.apache.org/couchdb/Replication_and_conflicts
The application-specific merging can be done by passing in a resolver or before calling a returned continuing function.
The bulkSave operation is not atomic, unlike the ruby example implementation. Not quite sure yet whether that is a good thing or not. http://localhost:5984/_utils/docs/api/database.html?highlight=bulk#post-db-bulk-docs
A good doc for the original jquery.couch.js version is http://bradley-holt.com/2011/07/couchdb-jquery-plugin-reference/ and http://daleharvey.github.io/jquery.couch.js-docs/symbols/index.html
I've modified it slightly so it can be run in the browser as will as on nodejs
An idea is to adapt it so it can be used with pouchdb as well, just by setting a parameter.
If you have an app that mainly talks to CouchDB it is nice to have a light weight adapter in the combination of couchapi and jquery.couch.js.
But if you want to add functionality for using the browser's internal indexedb you just add pouchdb.js to your site and set the parameter on couchapi, withouth changing any code of your app.
