Couch

• new Couch(options) - return value from require('couch')(url)
• Couch.get(id, cb) - get a document of the specified id
• Couch.post(doc, cb) - write a document. MUST have _id and _rev if already exists
• Couch.update(id, mutate, cb) - updated an existing document atomically (regardless of revision)

c.update('myid', function (doc) {doc.status = 'complete'}, function (e, info) {
 if (e) throw e
 console.log(info) // {seq:<seq>, id:<id>, rev:<rev>} 
}) 

Views

• Couch.all(opts, cb) - Hits the /db/_all_docs API which accepts similar arguments and has a simpilar return value to views but is an index of all documents in CouchDB.

c.all({keys:['onlykey1', 'onlykey2']}, function (e, results) {
  if (e) throw e
  console.log(results.rows) // [{id:onlykey1, rev:<rev>}, {id:onlykey2, rev:<rev>}]
})

• Couch.design(name).view(name).query(opts)

c.design('app').view('byProperty').query({key:'type', include_docs:true}, function (e, results) {
  console.log(results.rows)
})
