Resend Ruby and Rails SDK
—
Installation
To install Resend Ruby and Rails SDK, simply execute the following command in a terminal:
Via RubyGems:
gem install resend
Via Gemfile:
gem 'resend', '~>0.3.0'
Setup
First, you need to get an API key, which is available in the Resend Dashboard.
ruby
require "resend"
Resend.api_key = ENV["RESEND_API_KEY"]
or
ruby
require "resend"
Resend.configure do |config|
config.api_key = ENV["RESEND_API_KEY"]
end
Example
```rb require “resend”
Resend.api_key = ENV[“RESEND_API_KEY”]
params = { “from”: “[email protected]”, “to”: [“[email protected]”, “[email protected]”], “html”: “<h1>Hello World</h1>”, “subject”: “Hey” } r = Resend::Emails.send(params) puts r ```
You can view all the examples in the examples folder
Rails and ActiveMailer support
This gem can be used as an ActionMailer delivery method, add this to your config/environments/environment.rb file and replace with your api key.
ruby
config.action_mailer.delivery_method = :resend
config.action_mailer.resend_settings = {
api_key: 'resend_api_key',
}
After that you can deliver_now!, example below:
```ruby #/app/mailers/user_mailer class UserMailer < ApplicationMailer default from: ‘[email protected]’ def welcome_email @user = params[:user] @url = ‘http://example.com/login’ mail(to: [“[email protected]”, “[email protected]”], subject: ‘Hello from Resend’) end end
anywhere in the app
u = User.new name: “derich” mailer = UserMailer.with(user: u).welcome_email mailer.deliver_now! # => from: ‘[email protected]’, to: [“[email protected]”, “[email protected]”] ```
This gem can also be initialized with a Rails initializer file, example below:
ruby
# /app/initializers/mailer.rb
Resend.configure do |config|
config.api_key = 'resend_api_key'
end
