couchdb-jsonselect

JSONSelect For CouchDB

CSS-like selectors for JSON, which can be used over couch views.

• It makes it easy to access data in complex JSON documents.
• It feels like CSS.

See jsonselect docs for more details on the query

Install

npm i couchdb-jsonselect -g

Add jsonselect to a couchdb database

couchdb-jsonselect http://localhost:5984/databasename

jsonselect from a view

Assume you have a view named ddoc/myview. To select only the .languagesSpoken from each doc, use the following url

http://localhost:5984/databasename/_design/jsonselect/_list/select/ddoc/myview?include_docs=true&select=.languagesSpoken

You can use all the query parameters for the view, eg

http://localhost:5984/databasename/_design/jsonselect/_list/select/ddoc/myview?include_docs=true&select=.languagesSpoken&start_key="a"&end_key="b"

Retrieve Only Part Of A Doc

Lets say you have a doc with id abc3092390. To retrieve part of a doc, such as the .languagesSpoken property, use the following url

http://localhost:5984/databasename/_design/jsonselect/_show/select/abc3092390?select=.languagesSpoken

ldjson

We can also return ldjson from a view by adding the query parameter ?ldjson=true eg

http://localhost:5984/databasename/_design/jsonselect/_list/select/ddoc/myview?include_docs=true&select=.languagesSpoken&ldjson=true
