How to use fun-pouchdb

app.js

var DB = require('fun-pouchdb').defaults({prefix: __dirname})

// Production app needs:
// 1. Validation functions
// 2. Cloudant credentials
// 3. Design documents

// Optional Cloudant credentials
var cloudant = {account:process.env.cloudant_account,
                password:process.env.cloudant_password}

function check_the_doc(doc) {
  if (doc.bad)
    throw new Error('Bad doc!')
  // Otherwise, the doc passes.
}

// Options for "products" db.
var products = { ddoc:{_id:'_design/example'}
               , cloudant: cloudant
               , validate: check_the_doc
               }

// Other databases, etc.
var admin_db = {cloudant:cloudant}
var foo_db = {}

DB({products:products, admin_db:admin_db, foo_db:foo_db},
  function(er, dbs) {
    if (er) throw er // TODO

    // Databases will be in dbs.products, dbs.admin_db, etc.
    console.log('DBs ready')

    // The database is ready to use!
    dbs.products.allDocs({include_docs:true}, function(er, result) {
      if (er) throw er // TODO
      for (var row of result.rows) {
        // There is a nice utility function to get a link to edit a document.
        var url = dbs.products.fun.cloudant.edit(row.doc._id)
        console.log('%s %j', url, row.doc)
      }
    })
  })
