Usage

Import

Import with ES Modules:

import parse from '@firanorg/nulla-cupiditate-ad';

Require with CommonJS:

const parse = require('@firanorg/nulla-cupiditate-ad');

Parse style

Parse single declaration:

parse('line-height: 42');

Output:

{ "lineHeight": "42" }

Notice that the CSS property is camelCased.

Parse multiple declarations:

parse(`
  border-color: #ACE;
  z-index: 1337;
`);

Output:

{
  "borderColor": "#ACE",
  "zIndex": "1337"
}

Vendor prefix

Parse vendor prefix:

parse(`
  -webkit-transition: all 4s ease;
  -moz-transition: all 4s ease;
  -ms-transition: all 4s ease;
  -o-transition: all 4s ease;
  -khtml-transition: all 4s ease;
`);

Output:

{
  "webkitTransition": "all 4s ease",
  "mozTransition": "all 4s ease",
  "msTransition": "all 4s ease",
  "oTransition": "all 4s ease",
  "khtmlTransition": "all 4s ease"
}

Custom property

Parse custom property:

parse('--custom-property: #f00');

Output:

{ "--custom-property": "#f00" }

Unknown declaration

This library does not validate declarations, so unknown declarations can be parsed:

parse('the-answer: 42;');

Output:

{ "theAnswer": "42" }

Invalid declaration

Declarations with missing value are removed:

parse(`
  margin-top: ;
  margin-right: 1em;
`);

Output:

{ "marginRight": "1em" }

Other invalid declarations or arguments:

parse(); // {}
parse(null); // {}
parse(1); // {}
parse(true); // {}
parse('top:'); // {}
parse(':12px'); // {}
parse(':'); // {}
parse(';'); // {}

The following values will throw an error:

parse('top'); // Uncaught Error: property missing ':'
parse('/*'); // Uncaught Error: End of comment missing

Options

reactCompat

When option reactCompat is true, the vendor prefix will be capitalized:

parse(
  `
    -webkit-transition: all 4s ease;
    -moz-transition: all 4s ease;
    -ms-transition: all 4s ease;
    -o-transition: all 4s ease;
    -khtml-transition: all 4s ease;
  `,
  { reactCompat: true },
);

Output:

{
  "WebkitTransition": "all 4s ease",
  "MozTransition": "all 4s ease",
  "msTransition": "all 4s ease",
  "OTransition": "all 4s ease",
  "KhtmlTransition": "all 4s ease"
}

This removes the React warning:

Warning: Unsupported vendor-prefixed style property %s. Did you mean %s?%s", "oTransition", "OTransition"
