Is there a reliable way to detect file changes with PnP (nodejs) on Sharepoint?

Question

Im am using PnP nodejs to do certain tasks triggered by SP workflows. To detect whether an uploaded file has changed it's content - I have to retrieve file size or a content hash form the new upload. Unfortunately the item object delivered with ".getItem()" does not provide any hash or file size (with file.Modified it is not possible not reliably detect a file change):

sp.web
  .getFileByServerRelativePath(relativeUrl) //Eg. /Documents/a/file.txt
  .getItem()
  .then((file) => {...})

Any suggestions to retrieve this with PnP?

Or, is there a better and reliable way to detect whether a s specific file has changed on Sharepoint with PnP?

Answer 1

You could retrieve the file size use file.Length property, like the below:

  sp.web
    .getFileByServerRelativePath("/sites/test/Shared Documents/a.txt")
    .get()
    .then(file=>{
              console.log(file.Length)
          });
