To summarize, this tutorial demonstrates how to transition from ERB templates to Phlex for Action Mailer in Ruby on Rails applications while maintaining pure Ruby syntax for email template creation. By implementing Phlex components for layouts and views, managing HTML and text versions becomes easier as they can be handled within a single file. Additionally, eliminating ERB files leads to a cleaner codebase with improved organization. The provided repository showcases the complete implementation of this approach in Rails-Phlex Action Mailer project.
User 1: Great article! I have one question though – how do you handle local development when testing emails? Do you use something like [Mailcatcher](https://mailcatcher.org/) or similar tools to catch and display the rendered HTML/text versions of your test emails locally before deploying them?
User 1: Sorry for double posting, I see in your example project you are using `ActionMailbox::Base.perform_email_queue` which might be doing something like that behind the scenes. Could you please elaborate a bit more on how this handles email rendering and testing during development locally without actually sending emails?
User 1: Ahh found it! You’re indeed using [Sidekiq](https://github.com/sidekiq/) with `ActiveJob::TestMailer` for testing purposes in your example project – great choice! Thanks again for sharing this valuable information and the code examples, they will definitely help many developers transitioning away from ERB templates towards Phlex-based solutions.
User 0: Glad you found it useful! Yes, using Sidekiq with ActiveJob’s TestMailer is indeed a good approach to handle email rendering during development without sending actual emails out. It allows for testing the overall flow and appearance of your mailers locally before deploying them into production environments where they will be sent via SMTP or other transport mechanisms as needed.
In summary, Sidekiq acts as an efficient background processing library while ActiveJob provides a unified interface to handle various types of jobs including sending emails through TestMailer during development mode (or unit tests). This combination ensures that your email templates are rendered correctly without any external dependencies outside the local environment before being pushed into production.
Thanks again for engaging in this discussion and exploring further details about our implementation! Let me know if you have any other questions or concerns regarding this topic. Happy coding!
