This is a simple serverless application build over Jets framework of the ruby. The application illustrates how we can create a simple serverless email service using jets framework.
- RVM
- Ruby(2.5.1)
- AWS CLI
- Follow the steps given here: https://rvm.io/rvm/install, to install RVM in your machines
To install ruby(2.5.1) in your machine, run following command
$ rvm install ruby-2.5.1
$ sudo apt install awscli
$ aws configure
$ git clone https://github.com/SystangoTechnologies/serverless-ruby-simple-email.git
$ cd serverless-ruby-simple-email
$ bundle install
To start your the jets server locally, you need to run
$ jets s
It will start your service on http://localhost:8888.
To send email, you can hit the following endpoint as a POST request.
$ curl -X POST \
http://localhost:8888/send_email \
-H 'Authorization: {YOUR AUTHORIZATION KEY}' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-H 'cache-control: no-cache'
-d '{"sender": "[email protected]", "recipients": ["[email protected]", "[email protected]"],"subject": "Test email", "body": "<h1>Hi User!</h1>"}'
The required parameters in the request are:
- sender [string]: Email address of sender
- recipients [array]: Array of recipients emails.
- subject [string]: Subject of Email
- body [string]: Body of subject(HTML or normal text)
To deploy your application to AWS, you need to just run single command
$ jets deploy
Once the application is deployed you will get the API endpoint using which you can access Live API.
Once API gateway is created, you must setup Usage plan along with their API Keys form API gateway console. For this, you can follow the official doc for the same given by AWS.
If you want a custom authorization instead of this, just comment out the before_filter:authorize line in application.rb to make custom authorization work.
