Some commands in DEVELOPING.md don’t exist; Visual Editor dev server opens unexpected page

[aniruddhha]

Hi team 👋 — I’m setting up a local dev environment to contribute and ran into two problems:

1) DEVELOPING.md commands not found

The doc mentions these shortcuts:

npm run w     # bring up Breadboard Web UI
npm run d     # start doc site server
npm run s     # start board server + Web UI

But these scripts aren’t present in the root package.json on main in my checkout. Running them yields:

npm ERR! Missing script: "w"
npm ERR! Missing script: "d"
npm ERR! Missing script: "s"

Question: Have these scripts been renamed/moved/removed? If so, could the docs be updated with the current equivalents (or the workspace targets I should use)?

2) Visual Editor starts but browser opens an unexpected page (/landing/)

I can start the Visual Editor like this:

# from repo root
npm run dev -w packages/visual-editor
# or (UI-only via vite)
npm exec -w @breadboard-ai/visual-editor vite -- --host 127.0.0.1 --port 3001 --strictPort --open

The dev server starts successfully (Vite prints a local URL), but the browser opens an unexpected page that looks unrelated to Breadboard and redirects to /landing/. Two screenshots:

• Full page:
  

• Redirect snippet / location bar:
  

Notes / what I tried

• Verified the dev server is running and serving on the reported port.
• Opening the root path (/) still redirects to /landing/.
• Tried alternate ports (e.g., 3001, 5174) and hosts (localhost vs 127.0.0.1).
• (Suspicion) This might be a service-worker from a different app that previously used the same origin (host+port) and is intercepting navigation.

Questions:

1. What is the canonical way to launch the Visual Editor today (equivalent to npm run w)?
   • Should I use npm run dev -w @breadboard-ai/visual-editor or the @breadboard-ai/unified-server script?
2. Does the Visual Editor expect a specific route (root /), or is there a landing route that should load first?
3. Are there any service-worker registrations in dev that could cause redirect behavior? (If not, I’ll purge SW/site data locally as a workaround.)

Environment

• OS: macOS (Apple Silicon/Intel)
• Node: via nvm (from repo’s .nvmrc)
• npm: (from npm -v)
• Branch: main (fresh clone / up to date with upstream)
• Install: npm ci

Expected vs Actual

• Expected: A working dev command that opens the Breadboard Visual Editor at the root path.
• Actual:
  • Docs reference npm run w / d / s scripts that don’t exist.
  • Visual Editor dev server runs, but browser opens/redirects to an unrelated /landing/ page.

Anything I can do to help

• I can submit a PR to update DEVELOPING.md once I know the correct current commands.
• If the /landing/ redirect is a known dev quirk, I can document the workaround (e.g., use a clean port/host, clear service worker & site data).

Thanks in advance for the guidance! 🙏
