Installing

npm install blue-cot

Differences with Cot

• Returns Bluebird promises
• Class-less, thus a different initialization, but the rest of the API stays the same
• Consequently, blue-cot is this-free: no need to bind functions contexts!
• 4xx and 5xx responses will return rejected promises (should be handled with .catch)
• Adds some view functions goodies

Initialization

const bluecot = require('blue-cot')
const config = {
  // MUST
  hostname: 'localhost'
  port: 5984,

  // MAY
  ssl: true
  // use one of the two:
  // together
  auth: 'username:password'
  // or separated
  user: 'username'
  pass: 'password'
  // logs the generated URLs and body
  debug: true
}

const getDbApi = bluecot(config)

const db = getDbApi('some-db-name')

Those are the same than for cot-node. Just remember this difference in error handling: here, 4xx and 5xx responses from CouchDB will return rejected promises (should be handled with .catch)

Specific API

Additional database functions

fetch

takes doc ids, returns docs

db.fetch([ 'doc-1', 'doc-2', 'doc-3' ])
.then(function (docs) {
  docs[0]._id === 'doc-1' // true
  docs[1]._id === 'doc-2' // true
  docs[2]._id === 'doc-3' // true
})

View functions

To access those, pass a design doc name as second argument

const db = getDbApi('some-db-name', 'some-design-doc-name')

viewCustom

viewByKeysCustom

viewByKey

viewFindOneByKey

viewByKeys
