node.js sending by request module - node.js

Question

I need to send a lot of messages. I use external api and request module:
email.js
var request = require('request');
module.exports = function(subject, email){
var message = ... ;
var options = {
method: 'POST',
url: 'https://api.emails.net.com/api/sendmail',
form: {
smtp_account: smtp,
to: {},
subject: subject,
html: message,
from: 'myapp#email.com',
from_name: 'Myapp'
},
headers: {
'Authorization': ' ... '
}
};
request(options, function (error, response) {
if (!error && response.statusCode === 200) return true;
return false;
});
};
And in another place:
var sendEmail = require('../email');
...
for( ... ){
if(sendEmail(subject, email)){
//do something
}
}
After success i want to do something but request return nothing. Is any way to check if post was success and do something in place where I require email module? I'm sending emails in loop and i must check one by one.

You can do something like this
var request = require('request');
var Promise = require('bluebird');
var email = function () {
return {
send: function (subject, email) {
var message = "test";
var options = {
method: 'POST',
url: 'https://api.emails.net.com/api/sendmail',
form: {
smtp_account: "smtp",
to: {},
subject: subject,
html: message,
from: 'myapp#email.com',
from_name: 'Myapp'
},
headers: {
'Authorization': ""
}
};
return new Promise(function (resolve, reject) {
request(options, function (error, response) {
if (!error && response.statusCode === 200) {
resolve(true);
} else {
reject(err);
}
});
})
}
}
};
module.exports = email();
And then you can consume this as below
for (var i = 0; i < 10; i++) {
console.log(i);
email
.send("test", "test#gmail.com")
.then(function (status) {
///Do what ever u want to do
})
.catch(function (err) {
console.log(err);
});
}
