is_archive

A tiny Deno module to check whether if a file is an archive or not.

Usage

import { isArchive } from 'https://deno.land/x/[email protected]/mod.ts'

console.log(await isArchive('path/to/archive.tar'))

Important: you must run your program with --allow-read as this module needs to read the file.

Global install

You can install this module globally with:

deno install --allow-read -n is-archive mod.ts

Then use it from your CLI:

$ is-archive path/to/archive.tar
$ ✅ - path/to/archive.tar is an archive!

How it works

This module compares the first bytes of the input file to known archive formats magic bytes.
