How to Render RSS Feeds in Elixir Phoenix

This is an example of how to capture and display an RSS feed in Phoenix.

You must first install the Feedex RSS package.

Below is a LiveView example that uses the above package to render contents of an RSS feed to the browser.

The raw() method comes with Elixir Phoenix and is used to sanitize HTML.

Example

defmodule AppWeb.PageLive do
  use AppWeb, :live_view

  def mount(_params, _sesion, socket) do
    {:ok, socket}
  end

  def render(assigns) do
    {:ok, feed} = Feedex.fetch_and_parse("https://podcastfeeds.nbcnews.com/RPWEjhKq")

    [head | tail] = feed.entries
    IO.inspect(head.content)

    ~H"""
    <%= raw(head.content) %>
    """
  end
end
