I'm trying to read a binary file then parse it with DataView, but when passing the buffer from fs.readFile to DataView, it throws an Error

TypeError: First argument to DataView constructor must be an ArrayBuffer

here is my code:

const fs = require('fs');
const buf = fs.readFileSync('./path/to/file');
const dv = new DataView(buf);

the reason why I want to DataView instead of methods from Buffer(buf.readInt8([offset])) to read data is that I can share logic between node and browser

const fs = require('fs');
const buf = fs.readFileSync('./path/to/file');
const dv = new DataView(buf.buffer);
