How to build nested comments and threads in Ruby on Rails
Implementing polymorphic, reusable comments across models and limiting the nesting allowed for nested comment threads
Using AJAX, we can submit our comments and have them render onto the page without a page refresh.
Nested comment threads pose a lot of unique challenges. One of these is deleting comments because you can easily lose the child comments or context. We'll take a look at a couple great ways of handling this.
Adding pagination to our nested comment threads is easier than you might think, plus we'll take a look at a couple different approaches we can use
Deciding whether or not to have separate first and last name fields gets a bit confusing. Basecamp's recently released name_of_person gem shows you exactly how to handle this reliably and also stands as a fantastic example of how to build a concern

Cross-origin Resource Sharing (CORS) allows your website to talk to other websites.
We don't want anyone to be able to embed your Javascript widget on any domain, so we'll setup our app to check the domain and only allow the widget on specific sites
We can use webpacker to create scoped styles for our Javascript widget and build an embed code that links to the latest version of our webpacker JS and CSS for our embeddable widget.
