compressible
Advanced tools
The compressible npm package is used to determine if a given MIME type is compressible. This is useful when working with HTTP servers and clients to decide whether to apply compression to a particular resource based on its Content-Type.
Check if MIME type is compressible
This feature allows you to check if a specific MIME type is generally considered compressible. Text-based formats like HTML are typically compressible, while binary formats like PNG are not.
const compressible = require('compressible');
console.log(compressible('text/html')); // true
console.log(compressible('image/png')); // falseThe mime-types package provides a library for resolving a file's MIME type based on its extension. It can also look up the extension based on a MIME type. While it does not directly tell you if a MIME type is compressible, it can be used in conjunction with other libraries to make that determination.
The compression package is an Express middleware for Node.js that provides response compression. It automatically determines if the response should be compressed or not, using a similar logic to what compressible provides, but it is more focused on the actual compression process rather than just the determination.
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*/*+xmlIf 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
