I tried finding type of file using file-type module but when i try to run it gives me error that "error:.... fileType.fromBuffer is not a function.

`

const fileType = require('file-type');
const readChunk = require('read-chunk');
exports.ext = async function(file) {
const buffer = readChunk.sync(file, 0, 512)
let type = await fileType.fromBuffer(buffer);
console.log("type of file",type)
return value

`

this is in utils.js file and i am calling it in other type.js file

`

var extension =  await utils.ext('ABC.png')
 console.log(extension)

`

Can anybody tell me what should i do?

seems like there is a miss in npm documentation for the module file-type. The error which you are getting means the module doesn't expose such a method(fromBuffer).

Note that the function fromBuffer is now fileTypeFromBuffer in the latest version of the package.

the fileType accepts buffer as an input i.e.

await fileType.fileTypeFromBuffer(buffer)

kindly follow this file from the module source
