Compressible Content-Type
/ mime
checking.
$ npm install compressible
var compressible = require('compressible')
Checks if the given Content-Type
is compressible. The type
argument is expected
to be a value MIME type or Content-Type
string, though no validation is performed.
The MIME is looked up in the mime-db
and
if there is compressible information in the database entry, that is returned. Otherwise,
this module will fallback to true
for the following types:
text/*
*/*+json
*/*+text
*/*+xml
If this module is not sure if a type is specifically compressible or specifically
uncompressible, undefined
is returned.
compressible('text/html') // => true
compressible('image/png') // => false
