A promisified FileReader for browsers
A promisified FileReader implementation very similar to the browser's FileReader API, with a few differences:
- the File or Blob instance is given at construction time;
- all
readAs...methods don't take a Blob or File instance as first argument anymore; - all
readAs...methods return a Promise that can be awaited; - reading in chunks is easy as:
- you just need to await the next chunk (no event / callback API anymore);
- the current reading position is automatically tracked.
Usage
1import { FileReader } from '@tanker/file-reader'; 2 3// Retrieve a file or blob somehow 4const file = new File( 5 ['The quick brown fox jumps over the lazy dog'], 6 'fox.txt', 7 { type: 'plain/text' } 8); 9 10// Create your file reader 11const reader = new FileReader(file); 12 13// Read the whole file 14const text = await reader.readAsText('UTF-8'); 15const dataUrl = await reader.readAsDataURL(); 16const arrayBuffer = await reader.readAsArrayBuffer(); 17 18// Or read binary chunks (ArrayBuffer) 19const chunkSize = 8; // bytes 20let chunk; 21do { 22 chunk = await reader.readAsArrayBuffer(chunkSize); 23 // do something with the chunk 24} while (chunk.byteLength > 0);
