Email Sending using Aspose.Email Cloud in Heroku Ruby on Rails

Ruby on Rails, is a server-side web app framework. This article helps you set up Heroku app for Ruby on Rails, and how to use Aspose.Email Cloud for email sending.

Ruby on Rails, is a server-side web application framework written in Ruby. Rails is a model view controller framework, providing default structures for a database, a web service, and web pages. Heroku is a platform as a service (PaaS) that enables developers to build, run, and operate applications entirely in the cloud. It supports several programming languages including Ruby on Rails. This blog guides you on how to deploy a Ruby on Rails application to Heroku. The article helps you understand Aspose.Email Cloud, and how to use it for email sending using Heroku Ruby on Rails. The article assumes that you already have a free Heroku Account setup and Ruby and Bundler installed locally. Bundler provides a consistent environment for Ruby projects by tracking and installing the exact gems and versions that are needed. Let’s get started!

Setup Heroku

To get started you first need to install the Heroku Command Line Interface (CLI). Heroku CLI is used to manage and perform various scalability tasks. You can use this to provision add-ons, view your application logs, and run your application locally. If you are using macOS, you can use Homebrew to install it or can visit the official Heroku.

brew install heroku/brew/heroku

Once the installation is done you can run the following command to authenticate Heroku to be used locally.

heroku login
heroku: Press any key to open up the browser to login or q to exit
 ›   Warning: If browser does not open, visit
 ›   https://cli-auth.heroku.com/auth/browser/\*\*\*
heroku: Waiting for login...
Logging in... done
Logged in as me@example.com

This command opens your browser to the Heroku login page for authentication. This is required for both Heroku and git commands to work properly

Setup Aspose.Email Cloud

Aspose.Email Cloud is a Cloud SDK to send, receive, append, flag, and convert cloud emails & support to create a folder structure for email archiving in the cloud. This is easy to use and fast API, that doesn’t need to install the additional software. The API supports many programming languages, such as C#, Java, PHP, Python, Ruby & Typescript. To set up Aspose.Email Cloud follows the instructions as below.

Login to Aspose.Cloud Dashboard and click the Applications tab in the left sidebar. Now scroll down, click Create New Application button as shown in the image below.

Email Sending using Aspose.Email Cloud

Assuming you’ve already installed Ruby 2.7 and Bundler. You now have a functioning git repository that contains a simple application as well as Gemfile file which is used by Ruby’s dependency manager, bundler.

$ mkdir my-email-sending-app
$ cd my-email-sending-app
$ gem install aspose_email_cloud

add the following code in your ruby project

require 'aspose-email-cloud'
include AsposeEmailCloud

// Setup App Credentials 
@api = EmailCloud.new('client_secret', 'client_id')

credentials = EmailClientAccountPasswordCredentials.new(
  login: 'example@gmail.com', password: 'password')

// Setup an email account for email sending
send_account_dto = EmailClientAccount.new(
  host: 'smtp.gmail.com',
  port: 465,
  security_options: 'SSLAuto',
  protocol_type: 'SMTP',
  credentials: credentials)
smtp_account = 'smtp.account'
smtp_location = StorageFileLocation.new(
  storage: storage_name,
  folder_path: account_folder,
  file_name: smtp_account)
# Save account
api.client.account.save(ClientAccountSaveRequest.new(
  storage_file: smtp_location, value: send_account_dto))

email = EmailDto.new(
  from: MailAddress.new(address: 'example@gmail.com'),
  to: [MailAddress.new(address: 'to@aspose.com')],
  subject: 'Some subject',
  body: 'Some body'
)

api.client.message.send(
  ClientMessageSendRequest.new(
    account_location: smtp_location,
    message: MailMessageDto.new(value: email)))

Deploy to Heroku (Ruby on Rails)

Once you are done with all your changes and ready to deploy to Heroku (Ruby on Rails), you can use the following commands to push your changes to Heroku.

$ heroku create
Creating sharp-rain-221... done, stack is heroku-20
https://sharp-rain-221.herokuapp.com/ | https://git.heroku.com/sharp-rain-221.git
Git remote heroku added

this will create a git repository on Heroku and anything you push to this repo will deploy to Heroku(Ruby on Rails).

$ git push heroku main

Now you can open your application using the heroku open command.

Conclusion

In this article, we learned about the Heroku platform as a service (PaaS) and how it enables developers to build, run, and operate applications entirely in the cloud. We also learned how to set up a Heroku Ruby on Rails. We also explored the Aspose.Email Cloud, and used to set up an SMTP email client for email sending. Aspose.Email Cloud isn’t just for sending emails. Instead, it’s a Cloud SDK to send, receive, append, flag, and convert cloud emails & support to create a folder structure for email archiving in the cloud. This is easy to use and fast API, that doesn’t need to install the additional software. The API supports many programming languages, such as C#, Java, PHP, Python, Ruby & Typescript. I hope this article helped you.
