• $ npm install

Usage

There are three functions available in JavaScript: configure the minifiers, minify a string, and minify a file. Below an example of their usage:

import { config, string, file } from '@tdewolff/minify';

# default config option values
config({
    'css-precision': 0,
    'html-keep-comments': false,
    'html-keep-conditional-comments': false,
    'html-keep-default-attr-vals': false,
    'html-keep-document-tags': false,
    'html-keep-end-tags': false,
    'html-keep-whitespace': false,
    'html-keep-quotes': false,
    'js-precision': 0,
    'js-keep-var-names': false,
    'js-version': 0,
    'json-precision': 0,
    'json-keep-numbers': false,
    'svg-keep-comments': false,
    'svg-precision': 0,
    'xml-keep-whitespace': false,
})

const s = string('text/html', '<span style="color:#ff0000;" class="text">Some  text</span>')
console.log(s)  // <span style=color:red class=text>Some text</span>

file('text/html', 'example.html', 'example.min.html')  // creates example.min.html

Mediatypes

The first argument is the mediatype of the content. The following mediatypes correspond to the configured minifiers:

• text/css: CSS
• text/html: HTML
• image/svg+xml: SVG
• (application|text)/(x-)?(java|ecma)script: JS
• */json */*-json: JSON
• */xml */*-xml: XML
