Why @mdgate/text

Runs where your JavaScript runs

No separate processing service. The converter is TypeScript you can call from Node.js, Cloudflare Workers, Edge runtimes, and browsers.

Local conversion

CSS files can stay inside your application or browser.

Content detection

Recognizes CSS files from their contents, not only the filename.

Deterministic parsing

The same CSS file produces repeatable Markdown without model inference.

Small runtime surface

No Python. No native addons. No WASM. No third-party runtime dependencies.

FAQ

Can I convert CSS to Markdown without uploading it?

Yes. CSS files can be converted locally in the browser.

Does CSS to Markdown work in Cloudflare Workers?

Yes. @mdgate/text runs directly in Cloudflare Workers.

Does it require Python?

No.

Does it require native addons or WASM?

No.

What does it output?

GitHub-Flavored Markdown.

Can I install only the CSS converter?

Yes. Install @mdgate/text instead of the complete converter set.

Why pass a path?

The path selects treatment (paragraphs, pass-through Markdown, or a code fence). It is never used to read a file from disk.
