Salesforce Note content is stored in ContentVersion.VersionData as Base64. The LWC lightning-formatted-rich-text just displays BLOB(n bytes).
The SOQL in Apex looks like this:
notesList = [select Id,Title,TextPreview,VersionNumber,CreatedBy.Name,CreatedDate,VersionData
from ContentVersion
where isLatest = true
and ContentDocumentId = : noteIds
and FileType = 'SNOTE'];
The template HTML looks like this:
<template for:each={notes.data} for:item="note">
<p key={note.Id}>{note.Title}-{note.TextPreview}</p>
<lightning-formatted-rich-text key={note.Id} value={note.VersionData}></lightning-formatted-rich-text>
</template>
I'm developing a custom Notes control (LWC) to provide better functionality/features. I'm currently using a wired Apex method, which is returning the correct List of records.
Because Salesforce uses Base64 for rich text storge and they have a rich text formatting component, it seems natural that there should be a built-in solution, but I'm finding no information in the developer documentation.
