ensure-string
If required, convert the input value to a string.
The input value may be a Buffer, ArrayBuffer, Int8Array.
By default the conversion will consider that the text encoding is utf-8.
If the file contains an UTF-16 byte-order mark (BOM), this will be detected and default to utf-16le or utf-16be accordingly.
If the input value is a text, no change is done. The method returns the value without further processing.
Installation
$ npm i ensure-string
Usage
We have a text.txt file containing the string ABC.
import { ensureString } from '..';
import { readFileSync } from 'fs';
import { join } from 'path';
const blob = readFileSync(join(__dirname, 'test.txt')); // read the file as an ArrayBuffer
const text = ensureString(blob);
console.log(text); // the text is a string containing ÀBC`
