For those who don't like the FileReader
npm install screw-filereader
A promisified Blob reader and streamer was proposed. But not as a external API like FileReader... Nooo - this is prototyped to Blob/File directly!
This makes it easier to read stuff from Blob's and File's
Here is an example
// require('screw-filereader')
// import screw-filereader
arrayBuffer = await blob.arrayBuffer() // awaits a promise
text = await blob.text() // awaits a promise
stream = blob.stream() // returns a web ReadableStream
// Just bonuses
// ------------
dataUrl = await blob.dataUrl() // awaits a promise
json = await blob.json() // awaits a promise (rejects if fail to parse)
img = await blob.image([preventRevoke=false]) // awaits a new Image object (rejects if fail to load)
// .binaryString() has been avoided
// - Binaries just don't work well with strings face it.
// Send the blob with ajax instead or use ArrayBuffer if you want to work with the data
//
// Until someone gives me a good reason why I should add them
// returns a blob url (same as [webkit]URL.createObjectURL(blob))
// can also return null if it's not possible like on chrome for iOS...
url = blob.url() || await blob.dataUrl() // this is what blob.image() dose behind the scene...blob.image() will read the Exif rotation in jpeg images and rotate it accordingly
If streams are not implmented i can suggest web-streams-polyfill then you get all
the benefits of pipes as well ✌️
