I fixed #899. The major problem is due to lack of
FileReader
in Node.I also cleaned the logic of converting a blob into an array buffer. Note the fact:
FileReader.prototype.readAsArrayBuffer
andBlob.prototype.arrayBuffer
essentially does the same thing, but the former uses callback while the latter uses promise. Also, becauseFile
inheritsBlob
, we do not need to specially take care ofFile
.npm run test
seems fine. Tests all pass.
