Visual quick deploy

1. Fork the NodeWarden repository to your GitHub account
2. Open Cloudflare Workers & Pages
3. Choose Continue with GitHub and select your fork
4. Set build command to npm run build and deploy command to npm run deploy
   • For KV mode, change the deploy command to npm run deploy:kv
5. After deployment finishes, open the generated Workers URL

• The default Workers hostname may be unreachable on some networks. To use a custom domain, add it in Workers settings.

• If the site reports a missing JWT_SECRET, add it as a Secret in Workers settings. In production use a random string of at least 32 characters; do not use temporary or example values.

• To hide the Web Vault, add a text variable named HIDE_WEB_VAULT with the value 1 under Workers settings → Variables and Secrets. While enabled, server-hosted frontend pages and static assets return 404 Not Found, while the login, sync, attachment, icon, notification, and other server endpoints used by Bitwarden clients remain available; an already installed or cached PWA can continue using its local frontend. Delete the variable (or change it to anything other than 1) to restore the server-hosted Web Vault.

• In this flow you hand code to Cloudflare to build and deploy. wrangler.toml or wrangler.kv.toml in the repo defines binding names; the Worker initializes the D1 schema on first request—no manual SQL upload.

[!TIP] Default R2 vs optional KV:

Storage	Card required	Max single attachment / Send file	Free tier
R2	Yes	100 MB (soft limit, adjustable)	10 GB
KV	No	25 MiB (Cloudflare limit)	1 GB

• Manual: open your fork on GitHub; when the sync banner appears, click Sync fork → Update branch
