Enable Likes in modern page comments

[Maggan Wåhlin]

I´m working on an SPFx web part to show aggregated comments made within a site. I am able to get all info about a comment through REST:

https://xxx.sharepoint.com/sites/vmf-lab/_api/web/lists('${this.properties.pagelibraryid}')/GetItemById(${page.Id})/comments?$select=createdDate,text,replycount,likeCount,author/name&$expand=author

I want to display the likeCount for a comment, but it does not seem to be possible to like a comment on a modern page, only reply to it... Or am I missing something..?

HI @Maggan Wåhlin,

I think that liking comments might be something that is on its way. If you open the site with SharePoint Designer then you will see that there is a hidden list with a name like: Comments<GUID>

Within this list there is a set of fields related to likes. 

To answer you question, I don't think that you can like any comments at the moment.

Thank you @Pieter Veenstra.

I just pasted the REST-call above in Postman to get all comment properties. Works fine. Just surprising that there is a property named likeCount, when it isn´t possible to like a comment :)

Well, I guess good things happen to those who wait :)

indeed, I found the same when I tried the REST call. The likeCount is always set to 0 and the interface doesn't have an option to change it.

I wonder if it is possible to update the likeCount through the API.
