Timezone Handling in Phoenix LiveView

In the tutorial, the author discusses an enhanced method for allowing client browsers to communicate timezone information to the Phoenix LiveView server. This is an update to a previous strategy that involved setting up client hooks. The author suggests that the hook-based approach is not necessary and can be substituted by directly sending the client's timezone information in fewer steps. Initially, three round trips were needed: one for the HTTP connection, the second for the mount connection when the LiveView socket is created, and the third when the DOM component with the hook is mounted. However, by amending the code, this process can be reduced to two round trips, occurring immediately on the LiveView mount callback. The approach showcased includes 'smuggling' the timezone data into the 'params' field, extending from solely having a CSRF token to including the 'time_zone' parameter, which will be accessed in the LiveView via the 'connect_params' in the socket. This optimization eliminates the need for the hooks code and contributes to more efficient live view techniques.
