Why Restrict Access?
Understand the importance of access restriction in real-time applications built with Phoenix and Elixir. Explore how to use Phoenix.Token for authentication to prevent unauthorized socket connections and apply authorization to channels to ensure users access only their own data, enhancing overall application security.
We'll cover the following...
Overview
The last section explored the basics of real-time applications powered by Channels, which let us build simple real-time applications. However, there’s still more we need to know to build full-featured applications. This section will cover adding access restrictions to Sockets and Channels.
We’ll start this section by examining how to restrict access to Channels and Sockets to ensure that data is provided only to the right users. We’ll use a Phoenix.Token to pass authentication information from the server to the view ...
