Phoenix Framework & LiveView Thinking FAQs

Question 1

Is it compatible with the latest Phoenix versions?

Accepted Answer

Yes, it is designed for modern Phoenix development, including 1.8+ Scopes and advanced concurrency primitives like assign_async and start_async.

Question 2

Why does this skill prohibit database queries in mount/3?

Accepted Answer

In LiveView, mount/3 is called twice—once for the initial HTTP request and again for the WebSocket connection. Querying in mount leads to duplicate database load; moving queries to handle_params ensures they only run once per navigation.

Question 3

Can it help with real-time features and PubSub?

Accepted Answer

Yes, it provides best practices for scoping PubSub topics to prevent data leaks between tenants and suggests using GenServers for external polling to avoid overloading external APIs.

Question 4

How does this help with multi-tenant security?

Accepted Answer

It enforces a security-first pattern using Scopes to ensure every database query and PubSub subscription is automatically restricted to the authorized user or organization, preventing broken access control.

Question 5

Does it address common LiveView architectural pitfalls?

Accepted Answer

Absolutely. It identifies issues like stale socket state in Channel intercepts, the requirement of trap_exit for terminate/2, and CSS class precedence rules that often confuse developers.
