Authentication with Phoenix

Phoenix is an Elixir-based web development framework that follows the server-side Model View Controller (MVC) design pattern, comparable to frameworks like Ruby on Rails, Node’s Express.js, and Python’s Django. This tutorial details the process of adding authentication to a Phoenix application using the phx.gen.auth generator, which is favored for its flexibility, security, and adherence to Elixir’s best practices. It walks through steps like creating a Phoenix application, setting up PostgreSQL for data persistence, generating MVC components for HTML resources, and implementing authentication routes. The tutorial emphasizes using Mix, Elixir’s build tool, for managing dependencies and database configurations, and demonstrates how the phx.gen.auth generator simplifies the creation of authentication features by generating necessary files and routes. The tutorial also highlights how to protect routes with authentication by using specific Phoenix plugs, ultimately enabling a secure and functional web application setup.
