Phoenix

Phoenix is a web development framework written in Elixir, designed for implementing APIs and web applications. With components comparable to other popular frameworks like Django and Ruby on Rails, Phoenix offers high developer productivity alongside impressive application performance. Unique features such as channels for real-time functionality and pre-compiled templates for increased speed further distinguish Phoenix from its counterparts.

cd fly_project
Fly launch

You will receive a prompt on the URL to visit your app or you can check your dashboard to see the deployed app with all the details.

In conclusion, deploying Phoenix applications on Fly.io is a seamless and efficient process that combines the productivity and performance benefits of the Phoenix framework with the ease of use and scalability of Fly.io. By following the steps outlined in this article, developers can quickly bring their Phoenix applications to life and harness the full potential of both technologies.
