This is an example of how to capture and display an RSS feed in Phoenix.
This document assumes that you understand the basics of Liveview. This includes:
- Phoenix and Elixir installation
- Create an empty starter application
- How to create a basic Liveview application
- How to perform basic form submission
- How to create database seed data in Elixir Phoenix
- How to render database data to a Liveview page
To use this example 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 bundled 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
