## Summary Follow-up to #639. On mobile, validating the reconnect refresh from #639 surfaced a bandwidth regression: the active session's initial message-load effect re-fires on **every** mutation of the reactive sessions map, and one of those re-fires issues a redundant `force:false` fetch that races the authoritative `force:true` reload for the same — often very large — session. ## What happens (validated live on a real mobile device, 2 workspaces open) The active-session effect in `session-view.tsx` reads the whole session object: ```ts const session = () => props.activeSessions.get(props.sessionId) ``` Reading `session()` inside the `createEffect` subscribes it to the entire sessions map. During a foreground/reconnect refresh, each of the ~10 concurrent `loadMessages()` completions calls `setSessions`, re-firing the effect **20-40× per reconnect** (21 firings logged within a single millisecond). Most re-runs no-op via the `isLoading && !force` guard, but the firing that lands in the open window (`isLoading:false` + freshly invalidated flag) issues a real network fetch. On a ~6,578-message active session that produced a duplicate full download racing the authoritative reload: ``` loadMessages HTTP fetch (6578 msgs) force:false (5565ms) ← from this effect loadMessages HTTP fetch (6578 msgs) force:true (7802ms) ← authoritative reload ``` both in flight ~300ms apart, saturating the mobile link (sidebar fetches degraded from 1-4s to 10-11s; bounded retries could exhaust against `FOREGROUND_REFRESH_TIMEOUT_MS`). ## Fix Derive the active session id through a value-diffed `createMemo` and drive the effect from that memo instead of the full session object. The memo only notifies downstream when the id string actually changes, collapsing the storm to a single run per real session change while preserving existing behavior (load on activation and on session switch). This intentionally does **not** touch the authoritative `force:true` reload contract guarded by `session-request-authority.test.ts` — a generic in-flight dedupe was tried and correctly rejected by that test (force:true must always re-fetch), so narrowing the effect's reactive dependency is the right lever. ## Validation - `tsc --noEmit` clean - UI tests: 34/34 (group 1), 18/18 (authoritative group 2, `--conditions=browser --test-force-exit`, incl. `session-request-authority`) - Production UI build succeeds Root cause was captured live via a portable debug overlay (branch `debug/mobile-overlay`).

Getting Started
🖥️ Desktop App
Available as both Electron and Tauri builds — choose based on your preference.
Download the latest installer for your platform from Releases.
| Platform | Formats |
|---|---|
| macOS | DMG, ZIP (Universal: Intel + Apple Silicon) |
| Windows | NSIS Installer, ZIP (x64, ARM64) |
| Linux | Tauri deb, Electron portable tar.gz (x64) |
The Tauri deb is currently built and installation-tested on Ubuntu 24.04. Compatibility with older Debian-based distributions is not yet guaranteed.
💻 CodeNomad Server
Run as a local server and access via browser. Perfect for remote development.
npx @neuralnomads/codenomad --password <your-password> --launch
Authentication required: The server requires a password on first run. You can pass it via
--password, theCODENOMAD_SERVER_PASSWORDenvironment variable, or create anauth.jsonfile (see Server Documentation).
Self-signed certificate: On first launch with HTTPS enabled (the default), your browser will show a "Your connection is not private" warning. This is expected — the server generates a local self-signed certificate automatically. Click Advanced → Proceed to localhost to continue. For local-only use without the warning, run with
--https=false --http=true.
See Server Documentation for flags, TLS, auth, and remote access.
🧪 Dev Releases
Bleeding-edge builds from the dev branch:
npx @neuralnomads/codenomad-dev --password <your-password> --launch
SideCars
SideCars let you open local web tools inside CodeNomad as tabs.
Configuration
- Name: Display name used in CodeNomad
- Port: Local HTTP or HTTPS service running on
127.0.0.1:<port> - Base path: Mounted under
/sidecars/:id - Prefix mode:
- Preserve prefix forwards the full
/sidecars/:id/...path upstream - Strip prefix removes
/sidecars/:idbefore forwarding the request upstream
- Preserve prefix forwards the full
VSCode (OpenVSCode Server)
Run with Docker:
docker run -it --init -p 8000:3000 -v "${HOME}:${HOME}:cached" -e HOME=${HOME} gitpod/openvscode-server --server-base-path /sidecars/vscode
Add SideCar as:
- Name:
VSCode - Port:
http://127.0.0.1:8000 - Base path:
/sidecars/vscode - Prefix mode:
Preserve prefix
Terminal (ttyd)
Run with:
ttyd --writable zsh
Add SideCar as:

Requirements
- OpenCode CLI — must be installed and in your
PATH - Node.js 18+ — for server mode or building from source
Development
CodeNomad is a monorepo built with:
| Package | Description |
|---|---|
| packages/server | Core logic & CLI — workspaces, OpenCode proxy, API, auth, speech |
| packages/ui | SolidJS frontend — reactive, fast, beautiful |
| packages/electron-app | Desktop shell — process management, IPC, native dialogs |
| packages/tauri-app | Tauri desktop shell (experimental) |
Quick Start
git clone https://github.com/NeuralNomadsAI/CodeNomad.git
cd CodeNomad
npm install
npm run dev
Troubleshooting
macOS: "CodeNomad.app is damaged and can't be opened"
Gatekeeper flag due to missing notarization. Clear the quarantine attribute:
xattr -dr com.apple.quarantine /Applications/CodeNomad.app
On Intel Macs, also check System Settings → Privacy & Security on first launch.
Linux (Wayland + NVIDIA): Tauri App closes immediately
WebKitGTK DMA-BUF/GBM issue. Run with:
WEBKIT_DISABLE_DMABUF_RENDERER=1 codenomad-tauri
See full workaround in the original README.
