A fork of parse5, supporting for case-sensitive parsing.

parse5 automatically converts all tag names, attribute names and attribute values to lowercase. It's intended and they have no plans to support that (inikulin#210, inikulin#116).

This fork removed such auto-conversion (and it will be not compatible HTML spec, use it when you are sure what you are doing) and preserved the cases in the output AST.

npm i parse5-case-sensitive

If you want to override the original parse5 package, you can do it by adding the following to your package.json:

{
    "resolutions": {
        "parse5": "npm:parse5-case-sensitive@7.1.2-0"
    }
}

This fork is planned to be kept in sync with the original parse5 package, the versioning will be in sync with parse5 with an extra -0 suffix indicating the patch versions of parse5-case-sensitive.
