costco docs

costco is a small UI for bulk editing and adding CouchDB documents. It takes a map function and uses it to edit all the docs in the database, alternately it takes an array of JSON objects and adds them to the db.

For convenience it's a couchapp, so you can push it to any db like so:

git clone http://github.com/harthur/costco.git
cd costco
couchapp push . http://hostname:5984/mydatabase

and visit it at http://hostname:5984/mydatabase/_design/costco/index.html

Examples

change the error field of all docs

function(doc) {
  doc.error *= 100;
  return doc;
}

rename message field in all docs

function(doc) {
  doc.text = doc.message;
  delete doc.message;
  return doc;
}

delete all docs that have year less than 2010

function(doc) {
  if(doc.year < 2010)
    return null;
}

cut docs in db down to the first thousand

function(doc) {
  i = i + 1 || 1;

  if(i > 1000)
    return null;
}

add a doc to the db

{
  "name": "newdoc",
  "message": "addin"
}

add three docs to the db

{"name": "doc1","message": "addin"},
{"name": "doc2", "count": 20},
{"name": "doc3", "count": 14}
