Phoenix Views and Templates

Phoenix uses HEEx (HTML+EEx) templates for rendering dynamic HTML content. HEEx provides compile-time validation, security through automatic escaping, and a component-based architecture. Views in Phoenix are modules that organize template rendering logic and house reusable function components.

View Module Structure

Phoenix view modules use the embed_templates macro to load HEEx templates from a directory:

defmodule HelloWeb.HelloHTML do
  use HelloWeb, :html

  embed_templates "hello_html/*"
end

This automatically creates functions for each .html.heex file in the hello_html/ directory.
