@livebuzzevents/mime-matcher v1.0.6

MimeMatcher is very simple library for checking if mime type string is in allowed range. You can also match mime types agains wildcards, like */* or 'application/*'

Instalation

You can install it from npm:

npm install mime-matcher --save

Or you can download mime-matcher.min.js from the dist folder and then include it in html file:

<script src="mime-matcher.min.js"></script>

Usage

import MimeMatcher from 'mime-matcher'

const matcher = new MimeMatcher('image/gif')

matcher.match('image/gif') //true
matcher.match('image/jpeg') //false

You can also use wildcards:

import MimeMatcher from 'mime-matcher'

new MimeMatcher('image/*').match('image/gif') //true
new MimeMatcher('*/*').match('text/xml') //true

You can also use multiple mime types to match agains:

import MimeMatcher from 'mime-matcher'

const matcher = new MimeMatcher('image/*', 'text/*')

matcher.match('text/xml') //true
matcher.match('image/gif') //true
matcher.match('audio/mpeg') //false

Optional mime type parameter is ignored:

import MimeMatcher from 'mime-matcher'

const matcher = new MimeMatcher('text/xml')

matcher.match('text/xml; encoding=utf-8') //true

There is also function parse returning object containing data

import { parse as parseMimeType } from 'mime-matcher'

parseMimeType('application/json') 
/*
{
    valid: true
    type: "application",
    subType: "json"
}
*/

parseMimeType('text/xml; encoding=utf-8') 
/*
{
    valid: true
    type: "text",
    subType: "xml",
    parameter: "encoding=utf-8"
}
*/


parseMimeType('invalid') 
/*
{
    valid: false
}
*/

You can also import function isValid as shorthand for checking validity:

import { isValid as isValidMimeType } from 'mime-matcher'

isValidMimeType('text/xml') //true
