How to add an array of objects to parse.com db? - node.js

Question

I'm developing an application and need to add many items at a time.
How can I do that with node.js?
This is the npm module for parse.com but there is no method like
insertAll("Foo", [objs...], ...)
I don't want to insert single object every time.

Write a convenience function that interfaces between your application and parse.com. You will have to write the iteration code once (or debug mine)
var async = require('async');
var parseApp = require('node-parse-api').Parse;
var APP_ID = "";
var MASTER_KEY = "";
var parseApp = new Parse(APP_ID, MASTER_KEY);
function insertAll(class, objs, callback){
// create an iterator function(obj,done) that will insert the object
// with an appropriate group and call done() upon completion.
var insertOne =
( function(class){
return function(obj, done){
parseApp.insert(class, obj, function (err, response) {
if(err){ return done(err); }
// maybe do other stuff here before calling done?
var res = JSON.parse(response);
if(!res.objectId){ return done('No object id') };
done(null, res.objectId);
});
};
} )(class);
// async.map calls insertOne with each obj in objs. the callback is executed
// once every iterator function has called back `done(null,data)` or any one
// has called back `done(err)`. use async.mapLimit if throttling is needed
async.map(objs, insertOne, function(err, mapOutput){
// complete
if(err){ return callback(err) };
// no errors
var objectIds = mapOutput;
callback(null, objectIds);
});
};
// Once you've written this and made the function accessible to your other code,
// you only need this outer interface.
insertAll('Foo', [{a:'b'}, {a:'d'}], function(err, ids){
if(err){
console.log('Error inserting all the Foos');
console.log(err);
} else {
console.log('Success!);
};
});
