fileidentifier

This repo is a library for both Rust and Javascript (Node.js). It does not identify files using file extension but using magic number. So It helps you to check files better.

Installation

• For Rust, you can install it from crates.io
• For Node.js, It is available in npm

How to use

in Rust: ```rust use std::fs; use fileidentifier::check::{FileFormat, getfileformat, is_png};

fn main() -> Result<(), Box> { let file = fs::read("/usr/bin/whatever")?;

assert_eq!(FileFormat::Script, get_file_format(&file));

// or you can check the file format
let png = fs::read("/file/path/x.png")?;

assert_eq!(true, is_png(&png));

Ok(())

} ```

in Node.js:

```javascript const fi = require('fileidentifier')

let file = fs::readFileSync('/file/path/x.png')

console.log(fi.getFileFormat(file)) // It will print 'png'

// check the file format

console.log(fi.isPng(file)) // It will print true

```
