I needed something like premailer for rails, and after searching, I decided to make an easy-to-use library to handle inline styles and convert to text for emails. It’s straightforward, and it handles external stylesheets too!
Here’s an example with Bamboo using a Phoenix template:
def welcome_email do
new_email
|> subject("Email subject")
|> to("test@example.com")
|> from("test@example.com")
|> put_text_layout(false)
|> render("email.html")
|> premail()
end
defp premail(email) do
html = Premailex.to_inline_css(email.html_body)
text = Premailex.to_text(email.html_body)
email
|> html_body(html)
|> text_body(text)
end
I hope some of you’ll find this library useful!
