How do you send emails from Angular controllers on

问题:

I'm using the Mean.js stack and I'm having issues figuring out how to send emails using the nodemailer package from inside an AngularJS controller. I have the following code:

var mailOptions = {
    from: 'Hello <[e-mail]>',
    to: '[e-mail]',
    subject: 'email subject',
    text: 'email body',
    html: 'html body'
};

var smtpTransport = nodemailer.createTransport(config.mailer.options);
smtpTransport.sendMail(mailOptions, function(err) {
    if (!err) {
        res.send({
            message: 'Email has been sent'
        });
    }

    done(err);
});

But I receive the error ReferenceError: nodemailer is not defined. I've tried injecting the dependency into the controller using:

angular.module('offers').controller('OffersController', ['$scope', '$stateParams', '$location', 'Authentication', 'Offers', 'nodemailer',
    function($scope, $stateParams, $location, Authentication, Offers, nodemailer) {
    ...

but I only get the error Unknown provider: nodemailerProvider. I've also added the dependency to app/config/express.js as so nodemailer = require('nodemailer'), but still no luck.

I see in the npm package nodemailer/src/nodemailer.js the following lines:

function Nodemailer(transporter) {
...

and

module.exports.createTransport = function(transporter)
...

so I would assume that I could access the package through a global Nodemailer object, as so: Nodemailer.createTransport(...), but that is undefined as well.

Thanks for your help!

I think Nodemailer have to run on server side.

Just trigger the sending with a $http request from angular.

You can find an example here

If you're getting a reference error please check that you've installed nodemailer correctly with npm install nodemailer --save.

In your code, you cannot inject nodemailer in an angular controller because it is not a service or a provider.

You have 2 options:-

1. Assuming it is just available as a node package and you have already installed it, you can include the script in your html file from node_modules folder, and that way nodemailer will be available in your app as a global object. Personally, I won't use this approach, and take the 2nd approach.

2. This is the preferred option - Create an http endpoint on your node server which does the mailing bit using nodemailer. Then send an http request to the end point to do what you want.
