Attribute/Class Sorting Utility

A small utility that reorders attributes and class tokens in HTML markup to improve compression benefits while leaving all other content untouched.

Capabilities

Attribute ordering by frequency

• Given markup with repeated attributes across elements, return HTML whose attributes are ordered from most common attribute name to least common within each element; ties fall back to alphabetical order and no attributes are dropped. @test

Class token ordering by frequency

• Given markup with class lists sharing tokens across elements, return HTML whose class attribute values reorder tokens by descending token frequency across the document; ties are alphabetical and spacing is normalized to single spaces. @test

Isolated sorting (no extra minification)

• When only attribute/class sorting is requested, preserve all other markup (text nodes, comments, inter-tag whitespace) aside from the reordered attributes/classes. @test

Toggleable behaviors

• Options allow enabling or disabling attribute sorting and class-token sorting independently; disabling one leaves its original order untouched while the other still reorders. @test

 * @returns {string} Markup with requested sorting applied.
