How RB to Markdown works

  1. RB
  2. plain-text handling
  3. paragraphs · Markdown · code fences
  4. GitHub-Flavored Markdown

Built for JavaScript runtimes

Node.js

Read local files, uploads, S3/R2 objects, and other byte sources.

Cloudflare Workers

Normalize text files directly inside Workers without a second parser.

Browser

Convert RB locally without uploading it to a server.

Edge

Run the same TypeScript converter in compatible Edge runtimes.

What @mdgate/text extracts

  • .txt / .text: paragraphs
  • .md / .markdown / .mdx: passed through as Markdown
  • Source extensions: wrapped in a fenced code block

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

RB files can stay inside your application or browser.

Content detection

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

Deterministic parsing

The same RB file produces repeatable Markdown without model inference.

Small runtime surface

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

RB for AI agents

Turn RB files into content your agent can actually work with.

FAQ

Can I convert RB to Markdown without uploading it?

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

Does RB 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.

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.
