npm package for generating its file-type on basis of magic numbers!!
npm install get-typeandmime> Detect the File type of a Buffer/Uint8Array/ArrayBuffer
The file type is detected by checking the magic number#Magic_numbers_in_files) of the buffer.
This package is for detecting binary-based file formats, not text-based formats like .txt, .csv, .svg, etc.

const {getStreamFileType} = require("get-typeandmime")
const remoteFile = "https://static.remove.bg/sample-gallery/graphics/bird-thumbnail.jpg";
(async()=>{
console.log("Remote File Type:",await getStreamFileType(remoteFile));
})()
`
