upload.html - HTML upload sanitization

upload.html.is_html_file(file: UploadedFile) → bool

Check if a file is an HTML file or not.

upload.html.sanitize_html_file(file: UploadedFile) → UploadedFile

Sanitize uploaded HTML files using nh3.

HTML file content is sanitized so unsafe content, including script tags, is removed before the file is saved.

Non-HTML files are returned as-is.
