html-reduce
The html-reduce Node.js package provides a single function that boils down HTML to the simplest, obviously opinionated, form. The initial use case of html-reduce is normalizing RSS item-level descriptions and atom:summary elements to a simple form that can be easily rendered by a naïve client, with very limited HTML parsing capabilities, producing homgenous output.
html-reduce is a sanitize-html configuration.
Specification
Reduce all HTML to <h1>, <p>, <a>, and <br />, while retaining newline formatting of HTML and plain text input. Keep
text of ignored tags.
