something like

var promise = require("bluebird")  var data =  [                 {                     firstname: 'xxxxx',                     lastname: 'v',                     phone: '9999999999',                     dateofbirth: '2010-08-02',                     department: 'it',                     startdate: '2015-08-02',                     created: now,                     updated:                 },                 {                     firstname: 'yyyyy',                     lastname: 'k',                     phone: '8888888888',                     dateofbirth: '2011-08-02',                     department: 'it',                     startdate: '2015-08-02',                     created: now,                     updated:                 },             ];   promise.map(data, function(item) {     return req.db.employee.create(item)         .then(function(id){ return id })         .catch(myerror, function(e) {             e.item = item;             throw e;         }) }).then(function(idlist) {     res.send("success!"); }).catch(myerror, function(e) {     console.log("operation failed on " + e.item + ": " + e.message);     res.send("error!"); }); 

you need define myerror make work (https://github.com/petkaantonov/bluebird/blob/master/api.md#catchfunction-errorclassfunction-predicate-function-handler---promise)

p.s. sure, req.db.employee.create(item) should support promises, need promisify it: https://github.com/petkaantonov/bluebird/blob/master/api.md#promisepromisifyallobject-target--object-options---object
