+
+Early on in Cordova's existence, the [file-transfer
plugin](https://github.com/apache/cordova-plugin-file-transfer)
+was created to solve the [problem of downloading binary
files](https://issues.apache.org/jira/browse/CB-22).
+At the time, there weren't great options for solving this using
standards-compliant
+web APIs. The web took a twisty path to get to a solution (see
+[Firefox's
`sendAsBinary`](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/sendAsBinary)
+and the now-defunct [FileSystem
API](https://dev.w3.org/2009/dap/file-system/file-dir-sys.html)'s
+[BlobBuilder](https://developer.mozilla.org/en-US/docs/Web/API/BlobBuilder),
+among others), but today you can use our good friend
[XMLHttpRequest](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest)'s
+newest features, combined with some newer JavaScript types and objects, to
solve
+this problem. As a result,
+[Cordova is sunsetting the file-transfer
plugin](https://issues.apache.org/jira/browse/CB-13052).
+All of us at Apache Cordova don't want to leave y'all hanging, though, so
we
+thought it'd be a good idea to show you how to use these newer XHR
features to do
+what file-transfer lets you do, but in a way that will work in any modern
web
+browser to boot!
+
+## TL;DR
+
+Don't care about "standards" and all that mumbo jumbo? Just looking to
copy-paste
+your way to future-proofness? Fine, you'll need this:
+
+* MDN has a great overview on [Sending and Receiving Binary
Data](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Sending_and_Receiving_Binary_Data).
+* Check out my [little proof-of-concept
app](https://github.com/filmaj/xhr2test).
+ Some details:
+ * It
[uses](https://github.com/filmaj/xhr2test/blob/master/www/js/index.js#L31)
+ [localforage](https://github.com/localForage/localForage) as a storage
abstraction.
+ * The [`helpers.js`
file](https://github.com/filmaj/xhr2test/blob/master/www/js/helpers.js)
+ has two methods you'll need:
+ *
[`download_blob_via_xhr`](https://github.com/filmaj/xhr2test/blob/master/www/js/helpers.js#L59)
+ *
[`upload_blob_via_xhr`](https://github.com/filmaj/xhr2test/blob/master/www/js/helpers.js#L42)
+
+## The Long Version
