Blob: text() method
Note: This feature is available in Web Workers.
The text() method of the
Blob interface returns a Promise that resolves with a
string containing the contents of the blob, interpreted as UTF-8.
Syntax
js
text()
Parameters
None.
Return value
A promise that resolves with a string which contains the blob's data as a text string. The data is always presumed to be in UTF-8 format.
Usage notes
The FileReader method readAsText() is an older method that performs a similar function.
It works on both Blob and File objects. There are two key differences:
Blob.text()returns a promise, whereasFileReader.readAsText()is an event based API.Blob.text()always uses UTF-8 as encoding, whileFileReader.readAsText()can use a different encoding depending on the blob's type and a specified encoding name.
