Provide HTML/CSS using arguments, files, or JSON on stdin

Error message

Provide HTML/CSS using arguments, files, or JSON on stdin

What it means

If after all resolution html and css are both still undefined, there is nothing to share and the script refuses to proceed. This happens when no flags, no files, no positionals, and no usable stdin content were provided.

Solutions

1. Provide HTML or CSS via --html/--css, --html-file/--css-file, positional args, or JSON on stdin.
2. If scripting non-interactively, pipe the JSON payload explicitly.
3. Run with --help to see the accepted input forms.

Example fix

# before
bun .../index.mjs
# after
echo '{"html":"<div>hi</div>","css":"@import \"tailwindcss\";"}' | bun .../index.mjs

if (html === undefined && css === undefined) {
  throw new Error('Provide HTML/CSS using arguments, files, or JSON on stdin')
}

const hasInput = (o) => o.html !== undefined || o.css !== undefined || o.htmlFile !== undefined || o.cssFile !== undefined

When it happens

Trigger: Running the script in an interactive terminal with no arguments and no piped stdin; piping only whitespace to stdin; providing only one source via a path the script does not read.

Common situations: User runs the binary expecting a prompt; a wrapper that forgets to forward input; stdin is closed/empty in CI.
