Question 1

How to use PhoenixGon with Phoenix LiveView?

Accepted Answer

PhoenixGon can be used for initial page load data in LiveView apps, but it's often redundant as LiveView manages state via WebSockets. Ensure gon variables are set before LiveView mounts to avoid conflicts.

Question 2

PhoenixGon vs manually encoding JSON in templates – which is better?

Accepted Answer

PhoenixGon automates the process, reducing boilerplate and security risks from manual encoding. However, for simple, one-off data passes, manual encoding might offer more control and less overhead.

Question 3

How to secure sensitive data when using PhoenixGon?

Accepted Answer

Avoid putting secrets like API keys directly in gon variables. Use PhoenixGon's configuration to limit exposed data and rely on Phoenix's controller logic to sanitize inputs before passing to gon.

Question 4

Can PhoenixGon handle nested data structures?

Accepted Answer

Yes, PhoenixGon uses JSON libraries like Jason, so it can serialize any Elixir data structure that is JSON-encodable, including nested maps and lists, as shown in the assets method examples.

Question 5

How to integrate PhoenixGon with JavaScript frameworks like React?

Accepted Answer

Access window.Gon in React components during initialization or useEffect hooks. However, for better state management, consider passing gon data as props or using context instead of relying on globals.

Question 6

Is PhoenixGon still maintained and updated?

Accepted Answer

Check the GitHub repository for recent activity; as of the README, it has a build status and version 0.4.0, but for long-term projects, verify current support and compatibility with newer Phoenix versions.
