.htmlnanorc

{
  "removeAttributeQuotes": false,
  "removeComments": false
}

command: parcel build src/index.html --dist-dir _dist

🤔 Expected Behavior

HTML comments and attribute quotes are kept in the resulting HTML.

😯 Current Behavior

Comments are kept, but attribute quotes are still removed.

💁 Possible Solution

Maybe parcel doesn't support all htmlnano config settings? Adding support for "removeAttributeQuotes" would make sense.

🔦 Context

Before upgrading parcel, my resulting html had quotes. Upgrading parcel led to things breaking for me due to no quotation marks. It made the migration bumpier.

According to parcel docs, parcel's internal html minimizer is compatible with htmlnano configs: "Parcel uses its builtin HTML minifier, which is compatible htmlnano." https://parceljs.org/languages/html/#minification

"removeAttributeQuotes" is a htmlnano setting: https://htmlnano.netlify.app/modules#removeattributequotes

💻 Code Sample

🌍 Your Environment

Operating System	win 10

Why are the quotes important? What is this breaking? Quotes are not required by the html spec.

[bitbof]

Some after the fact parsing reliant on quotes broke. It would have been nice to have the option to disable for an easier migration. It would be good for the docs to say which options are supported to avoid confusion.

I could have enabled htmlnano.
