Parse XML Blobs

Control whether or not LogRocket parses blobs in response bodies

Enable parsing of Blobs from XMLHTTPRequest response bodies

shouldParseXHRBlob - Boolean

optional (default - false)

LogRocket will save XMLHTTPRequest bodies of responseType Blob as [object Blob] by default in the network request details. To have Blobs that encode JSON text decoded, enable this option.

If you want to enable this feature, add this option to your configuration:

LogRocket.init(YOUR_APP_ID, {
  shouldParseXHRBlob: true,


The popular package cross-fetch provides an implementation of fetch() using XMLHTTPRequests. In order to avoid having all fetch response bodies recorded as Blobs, enable this option.
