How to Update Version Numbers Between Server and Client
In order to effectively communicate version numbers between the server and client, it is recommended to utilize the existing data transfer method, such as an API or sockets.
Upon each response, it is advisable to include the current application version in the header of the message, as suggested by Kevin B in the comments section.
Handling Version Changes on the Client Side
Once the client receives the version number from the server, it should be able to adapt to any changes accordingly. Different actions can be taken based on the type of version update - whether it's a patch, feature, or major change.
For instance, a patch update may prompt the user to reload the page for updated functionality, while a major version change could temporarily disable the site until the user refreshes to regain access.
It is important to note that automatic reloading without warning can lead to user experience issues, particularly in cases of data loss. It is advised to avoid this approach, especially for minor version updates.
Additional Considerations:
If direct communication methods like APIs are not available, polling an endpoint for version updates can also be implemented on the client side. While polling may not be the most elegant solution, it is preferable to setting up automatic reloads at intervals, which might disrupt user experience unnecessarily.
