Detect Archive Type
This feature allows you to detect the type of an archive file by reading its buffer. The code sample reads a file into a buffer and then uses the archiveType function to determine the file type.
const archiveType = require('archive-type');
const fs = require('fs');
const buffer = fs.readFileSync('example.zip');
const type = archiveType(buffer);
console.log(type); // { ext: 'zip', mime: 'application/zip' }The file-type package is used to detect the file type of a Buffer/Uint8Array/ArrayBuffer. It supports a wide range of file types, including archives, images, videos, and more. Compared to archive-type, file-type offers broader file type detection capabilities.
The detect-file-type package is another library for detecting file types from a buffer. It supports various file formats, including archives. While similar to archive-type, it also provides additional functionalities for detecting other file types.
