Type-teller

The file type is detected by checking the magic number of the buffer.

This package is for detecting binary-based file formats

Installation

``bash
npm install type-teller
`

Usage

`javascript
// javascript
const { detectFileType } = require("type-teller");
// typescript
import { detectFileType } from "type-teller";
//
const pathToFile = "./myImage.png";
const buffer = fs.readFileSync(pathToFile);
const type = detectFileType(buffer);
console.log(type); // Outputs: { ext: 'png' mime: 'image/png' }
`

Determine file type from extension:

This is NOT recommended for critical applications. This method assumes that the file extension matches the actual file type.
This only checks the file extension.

`javascript
// javascript
const { fileTypeFromFile } = require("type-teller");
// typescript
import { fileTypeFromFile } from "type-teller";

const pathToFile = "./myVideo.mp4";
const type = fileTypeFromFile();
console.log(type); // Outputs: { ext: 'mp4', mime: 'video/mp4' }
``
