rmux-web-share

Standalone static frontend for share.rmux.io.

The browser receives an rmux web-share URL, strips the secret fragment from the address bar, and connects directly to the daemon WebSocket endpoint from the browser. Terminal data does not transit through share.rmux.io.

Development

npm ci
npm run dev

Open:

http://127.0.0.1:4321/#t=<token>

Build

npm run build

The static output is written to dist/. The build also writes:

• dist/.well-known/rmux-web-share.json: deployed commit, build run, Cloudflare project, and asset hashes.
• dist/checksums.txt: SHA-256 checksums for the public assets.

Verification

Each deployment exposes public provenance:

curl https://share.rmux.io/.well-known/rmux-web-share.json
curl https://share.rmux.io/checksums.txt

To compare the deployed frontend with the source:

git clone https://github.com/Helvesec/rmux-web-share.git
cd rmux-web-share
git checkout <commit-from-rmux-web-share-json>
npm ci
npm run build
sha256sum dist/index.html

The GitHub Actions run summary also records the GitHub SHA-1 and Cloudflare Pages deployment URL.
