Screw-FileReader

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
