detect-content-type
Javascript module to determine the Content-Type of the given data, using the algorithm specified in the MIME Sniffing Standard.
This module is useful in cases where it is not possible to determine the Content-Type of the data using filename extension, either because file does not have an extension or the filename is not available.
Installation
npm install detect-content-type
or
yarn add detect-content-type
Import
ES6 and above:
import detectContentType from 'detect-content-type'
Using CommonJS:
var detectContentType = require('detect-content-type')
Usage
detectContentType takes a Buffer, and determines its Content-Type. It considers at most
512 bytes of data. detectContentType always returns a valid MIME type. If it cannot determine a
more specific one, it returns application/octet-stream.
let ct = detectContentType(Buffer.from("<html><body></body></html>")) // returns 'text/html; charset=utf-8'
Credits
The code in this module is ported nearly line-by-line from the http.DetectContentType method in the Go standard library.
