SPFX sharepoint online webpart subscibe to list webhooks

Question

Hi all,
I would like to know if is possible to develop spfx Sharepoint online webpart with similar behaviour which is in standard SharePoint list (document library) view webpart for example - when data in underline list is updated web part is automatically updated without any page reload.
I know about this possible solutions:

1. query list in intervals and check for update
2. Use webhooks on list with combination with custom Azure Functions -> SignalR or something similar.

Is there any simple solution how for example sign for webhook directly in webpart.
Thank you.
Tomas

Answer 1

In my opinion, webhook is a better choice than scheduled request, but scheduled request is much simpler.
Here is a tutorial combining webhook with SPFX, you can refer to it：

I know about this option and I have read this article before.. I was looking if there is 3th option for described scenario.
If there is no then i will have to live with it :).

Answer 3

If somebody is also looking for solution without webhooks or calling list in interval as I have specified in question. There is nice option for Libraries->
https://learn.microsoft.com/en-us/sharepoint/dev/spfx/subscribe-to-list-notifications
But this is only for libraries -> some workaround needs to be implemented anyway
Would be nice if subscribe would be available for List as well :(
