NPM version NPM downloads Build Status js-standard-style Security Responsible Disclosure

Installation

$ npm install fast-content-type-parse

Usage

const fastContentTypeParse = require('fast-content-type-parse')

fastContentTypeParse.parse(string)

const contentType = fastContentTypeParse.parse('application/json; charset=utf-8')

Parse a Content-Type header. Throws a TypeError if the string is invalid.

It will return an object with the following properties (examples are shown for the string 'application/json; charset=utf-8'):

  • type: The media type (the type and subtype, always lower case). Example: 'application/json'

  • parameters: An object of the parameters in the media type (name of parameter always lower case). Example: {charset: 'utf-8'}

fastContentTypeParse.safeParse(string)

const contentType = fastContentTypeParse.safeParse('application/json; charset=utf-8')

Parse a Content-Type header. It will not throw an Error if the header is invalid.

This will return an object with the following properties (examples are shown for the string 'application/json; charset=utf-8'):

  • type: The media type (the type and subtype, always lower case). Example: 'application/json'

  • parameters: An object of the parameters in the media type (name of parameter always lower case). Example: {charset: 'utf-8'}

In case the header is invalid, it will return an object with an empty string '' as type and an empty Object for parameters.
