JSPM – @tdewolff/minify@2.11.11

Package Exports

@tdewolff/minify
@tdewolff/minify/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@tdewolff/minify) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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
