Every .md under docs/{architecture,guides,reference,frameworks,routing,
security,compression,ops,diagrams} plus docs/README.md now opens with:
---
title: "<inferred from first H1>"
version: 3.8.0
lastUpdated: 2026-05-13
---
46 files updated (no docs were skipped — none had pre-existing
frontmatter). [slug]/page.tsx already reads frontmatter.version and
frontmatter.lastUpdated via gray-matter and renders a "v3.8.0" pill
plus a "Last updated" caption, so the UI picks these up automatically.
Helper: scripts/docs/add-frontmatter.mjs — idempotent (skips files that
already start with `---`), falls back to a humanized basename when no
leading H1 exists. Excludes docs/i18n/, docs/screenshots/,
docs/superpowers/, docs/diagrams/exported/. Re-runnable safely.
Also regenerated src/app/docs/lib/docs-auto-generated.ts: 44 docs across
8 sections (Architecture / Guides / Reference / Frameworks / Routing /
Security / Compression / Ops), which now includes the 14 docs that were
missing from the v3.7 sidebar (Cloud Agents, Guardrails, Memory, Skills,
Webhooks, Evals, Authz, Agent Protocols, Repository Map, Provider
Reference, Reasoning Replay, Stealth Guide, Tunnels Guide, Electron
Guide).

# Electron Desktop Guide
|
||
|
||
> **Source of truth:** `electron/` workspace
|
||
> **Last updated:** 2026-05-13 — v3.8.0
|
||
|
||
OmniRoute ships a cross-platform desktop app (Windows / macOS / Linux) built on
|
||
**Electron 41** + **electron-builder 26.10**. The desktop app spawns the Next.js
|
||
standalone server as a child process, points a `BrowserWindow` at it, and adds a
|
||
system tray, auto-updater, IPC bridge, and zero-config secret bootstrap.
|
||
|
||
## Architecture
|
||
|
||
```
|
||
┌──────────────────────────────────────────────┐
|
||
│ Electron main process (electron/main.js) │
|
||
│ ├─ Single-instance lock │
|
||
│ ├─ Child process: Next.js standalone server │
|
||
│ │ (spawned with Electron's Node runtime) │
|
||
│ ├─ BrowserWindow → http://localhost:PORT │
|
||
│ ├─ System tray + context menu │
|
||
│ ├─ Auto-update via electron-updater │
|
||
│ ├─ Content Security Policy (session headers) │
|
||
│ └─ Secret bootstrap (JWT / API_KEY_SECRET) │
|
||
└──────────────────────────────────────────────┘
|

|
||
┌──────────────────────────────────────────────┐

|
||
## Versions
|
||
|
||
Confirmed from `electron/package.json`:
|
||
|
||
| Package | Version |
|
||
| ------------------ | -------------------------- |
|
||
| `electron` | `^41.5.1` |
|
||
| `electron-builder` | `^26.10.0` |
|
||
| `electron-updater` | `^6.8.5` |
|
||
| `better-sqlite3` | `^12.9.0` |
|
||
| App version | `3.8.0` |
|
||
| App id | `online.omniroute.desktop` |
|
||
| Product name | `OmniRoute` |
|
||
|
||
## Scripts (root `package.json`)
|
||
|
||
| Script | Purpose |
|
||
| --------------------------------- | -------------------------------------------------------------------------- |
|
||
| `npm run electron:dev` | Starts `npm run dev` + waits for `localhost:20128` + launches Electron |
|
||
| `npm run electron:build` | Builds Next.js then runs `electron-builder` for the current OS |
|
||
| `npm run electron:build:win` | Builds Windows NSIS installer + portable (x64) |
|
||
| `npm run electron:build:mac` | Builds macOS DMG (Intel + Apple Silicon) |
|
||
| `npm run electron:build:linux` | Builds Linux AppImage + DEB (x64 + arm64) |
|
||
| `npm run electron:smoke:packaged` | Launches packaged binary and probes `/login` for HTTP 200, then shuts down |
|
||
|
||
The `electron/` workspace also exposes:
|
||
|
||
- `npm run prepare:bundle` — runs `scripts/build/prepare-electron-standalone.mjs`
|
||
- `npm run build:mac-x64` / `build:mac-arm64` — single-arch macOS builds
|
||
- `npm run pack` — directory-only build for local testing (no installer)
|
||
|
||

|
||
```
|
||
|
||
Both `main.js` and `preload.js` are **CommonJS `.js` files**, not TypeScript. The
|
||
renderer-side typings live in `electron/types.d.ts`.
|
||
|
||
## IPC Bridge (`preload.js`)
|
||
|
||
The preload exposes a whitelisted API on `window.electronAPI` using `contextBridge`
|
||
with `contextIsolation: true` and `nodeIntegration: false`.
|
||
|
||
```javascript
|
||
const VALID_CHANNELS = {
|
||
invoke: [
|
||
"get-app-info",
|
||
"open-external",
|
||
"get-data-dir",
|
||
"restart-server",
|
||
"check-for-updates",
|
||
"download-update",
|
||
"install-update",
|
||
"get-app-version",
|
||
],
|
||
send: ["window-minimize", "window-maximize", "window-close"],
|
||
receive: ["server-status", "port-changed", "update-status"],
|
||
};
|
||
```
|
||
|
||
Exposed methods:
|
||
|
||
| Renderer call | Type |
|
||
| ----------------------------------------------------------------- | -------------------------- |
|
||
| `getAppInfo()` → `{ name, version, platform, isDev, port }` | invoke |
|
||
| `openExternal(url)` | invoke |
|
||
| `getDataDir()` | invoke |
|
||
| `restartServer()` | invoke |
|
||
| `getAppVersion()` | invoke |
|
||
| `checkForUpdates()` / `downloadUpdate()` / `installUpdate()` | invoke |
|
||
| `minimizeWindow()` / `maximizeWindow()` / `closeWindow()` | send |
|
||
| `onServerStatus(cb)` / `onPortChanged(cb)` / `onUpdateStatus(cb)` | receive (returns disposer) |
|
||
|
||
The receive helpers return a **disposer function** rather than relying on
|
||
`removeAllListeners` — this prevents listener accumulation when React components
|
||
remount.
|
||
|
||
## Server Lifecycle
|
||
|
||
`main.js` spawns the Next.js standalone bundle directly with the Electron Node
|
||
runtime to avoid native-module ABI mismatch with system Node:
|
||
|
||
```js
|
||
spawn(process.execPath, [serverScript], {
|
||
cwd: NEXT_SERVER_PATH,
|
||
env: { ...serverEnv, PORT, NODE_ENV: "production", ELECTRON_RUN_AS_NODE: "1", NODE_PATH },
|
||
stdio: "pipe",
|
||
});
|
||
```
|
||
|
||
Highlights:
|
||
|
||
- `waitForServer()` polls the URL up to 30 s before showing the window (no blank screen on cold start).
|
||
- `stdio: "pipe"` captures stdout/stderr; ready phrases (`Ready` / `listening`) emit `server-status: running` over IPC.
|
||
- `before-quit` waits up to 5 s for graceful SIGTERM (WAL checkpoint) then sends SIGKILL.
|
||
- Port switcher in the tray (`20128`, `3000`, `8080`) stops and restarts the server, then reloads the BrowserWindow.
|
||
|
||
## Zero-config Secret Bootstrap
|
||
|
||
On first launch, the main process auto-generates and persists missing secrets:
|
||
|
||
| Secret | Source |
|
||
| ------------------------ | ----------------------------------------------------------------------------------- |
|
||
| `JWT_SECRET` | `crypto.randomBytes(64).toString("hex")` |
|
||
| `STORAGE_ENCRYPTION_KEY` | `crypto.randomBytes(32).toString("hex")` (refuses if encrypted creds already exist) |
|
||
| `API_KEY_SECRET` | `crypto.randomBytes(32).toString("hex")` |
|
||
|
||
Persisted to `<DATA_DIR>/server.env`. `DATA_DIR` resolves to:
|
||
|
||
- Windows: `%APPDATA%\omniroute`
|
||
- Linux: `$XDG_CONFIG_HOME/omniroute` or `~/.omniroute`
|
||
- macOS: `~/.omniroute`
|
||
|
||
## Window & Tray
|
||
|
||
- `BrowserWindow`: 1400×900 (min 1024×700), `backgroundColor: "#0a0a0a"`.
|
||
- macOS: `titleBarStyle: "hiddenInset"`, traffic-light at `{ x: 16, y: 16 }`.
|
||
- Windows/Linux: native title bar.
|
||
- Close button minimizes to tray; the tray menu has **Open OmniRoute**, **Open Dashboard** (external browser), **Server Port** submenu, **Check for Updates**, **Quit**.
|
||
|
||
## Content Security Policy
|
||
|
||
Set via `session.defaultSession.webRequest.onHeadersReceived`. Notable directives:
|
||
|
||
- `frame-ancestors 'none'`, `object-src 'none'`, `child-src 'none'`
|
||
- `connect-src 'self' http://localhost:* http://127.0.0.1:* ws://localhost:* ws://127.0.0.1:* https://*.omniroute.online https://*.omniroute.dev`
|
||
- Dev mode adds `'unsafe-eval'` to `script-src` only
|
||
|
||
## Auto-update
|
||
|
||
Uses `electron-updater` with the GitHub provider (`diegosouzapw/OmniRoute`).
|
||
|
||
- `autoDownload = false`, `autoInstallOnAppQuit = true`
|
||
- Events forwarded to renderer via `update-status` IPC:
|
||
`checking`, `available`, `not-available`, `downloading` (with `percent`), `downloaded`, `error`
|
||
- `installUpdate()` kills the server then calls `autoUpdater.quitAndInstall()`
|
||
- Skipped in dev mode (`!app.isPackaged`)
|
||
|
||
## Build Pipeline
|
||
|
||
1. `npm run build` → Next.js standalone in `.next/standalone`.
|
||
2. `prepare-electron-standalone.mjs` → re-stages into `.next/electron-standalone` and rewrites absolute paths inside `server.js` + `required-server-files.json` so the bundle is relocatable.
|
||
3. `electron-builder` packages `main.js`, `preload.js`, `node_modules`, and `extraResources: { ../.next/electron-standalone → app }`.
|
||
|
||
### Build targets
|
||
|
||
| OS | Targets |
|
||
| ------- | ----------------------------------------- |
|
||
| Windows | NSIS installer + portable (x64) |
|
||
| macOS | DMG (Intel + arm64, drag-to-Applications) |
|
||
| Linux | AppImage + DEB (x64 + arm64) |
|
||
|
||
NSIS settings: `oneClick: false`, lets the user choose the install directory, creates Desktop and Start-Menu shortcuts.
|
||
|
||
## Smoke Testing Packaged Build
|
||
|
||
```bash
|
||
npm run electron:smoke:packaged
|
||
```
|
||
|
||
`scripts/dev/smoke-electron-packaged.mjs`:
|
||
|
||
- Auto-discovers the packaged binary in `electron/dist-electron/` for the current platform.
|
||
- Launches with isolated `HOME`/`APPDATA`/`XDG_*` directories so it doesn't touch developer data.
|
||
- Polls `http://127.0.0.1:20128/login` for HTTP 200 within 45 s.
|
||
- Watches stderr/stdout for fatal patterns (`Cannot find module`, `MODULE_NOT_FOUND`, `ERR_DLOPEN_FAILED`, `Failed to start server`, etc.).
|
||
- Waits 2 s of stable runtime after readiness, then issues SIGTERM and waits for the port to free.
|
||
- In CI, automatically passes `--no-sandbox --disable-gpu` (and `--disable-dev-shm-usage` on Linux).
|
||
|
||
Env overrides: `ELECTRON_SMOKE_APP_EXECUTABLE`, `ELECTRON_SMOKE_URL`, `ELECTRON_SMOKE_TIMEOUT_MS`, `ELECTRON_SMOKE_SETTLE_MS`, `ELECTRON_SMOKE_DATA_DIR`, `ELECTRON_SMOKE_KEEP_DATA`, `ELECTRON_SMOKE_STREAM_LOGS`.
|
||
|
||
## Code Signing
|
||
|
||
`electron/package.json` does **not** wire signing credentials directly. Pass them via env vars to `electron-builder`:
|
||
|
||
### macOS
|
||
|
||
```bash
|
||
export APPLE_ID=<email>
|
||
export APPLE_APP_SPECIFIC_PASSWORD=<password>
|
||
export APPLE_TEAM_ID=<id>
|
||
export CSC_LINK=path/to/cert.p12
|
||
export CSC_KEY_PASSWORD=<cert-password>
|
||
npm run electron:build:mac
|
||
```
|
||
|
||
### Windows
|
||
|
||
```bash
|
||
export CSC_LINK=path/to/cert.pfx
|
||
export CSC_KEY_PASSWORD=<cert-password>
|
||
npm run electron:build:win
|
||
```
|
||
|
||
### Linux
|
||
|
||
AppImage signing is optional — set `LINUX_GPG_KEY` if signing.
|
||
|
||
## Distribution
|
||
|
||
Artifacts land in `electron/dist-electron/`:
|
||
|
||
- `OmniRoute Setup X.Y.Z.exe`, `OmniRoute-X.Y.Z-portable.exe` (Windows)
|
||
- `OmniRoute-X.Y.Z-mac.dmg`, `OmniRoute-X.Y.Z-arm64-mac.dmg` (macOS)
|
||
- `OmniRoute-X.Y.Z.AppImage`, `omniroute-desktop_X.Y.Z_amd64.deb` (Linux)
|
||
|
||
Releases are published to GitHub Releases (`diegosouzapw/OmniRoute`), which is also where `electron-updater` checks for new versions.
|
||
|
||
## Troubleshooting
|
||
|
||
| Symptom | Fix |
|
||
| --------------------------------------------------------------- | --------------------------------------------------------------------------- |
|
||
| `Cannot find module 'better-sqlite3'` after Electron major bump | `cd electron && npm rebuild` |
|
||
| `ERR_DLOPEN_FAILED` for native module | Re-run `prepare:bundle` and verify ABI matches Electron's Node |
|
||
| Window appears blank on Linux | Confirm Next.js server actually bound to PORT (check `[Server]` logs) |
|
||
| macOS notarization stalls | Ensure `APPLE_*` vars are exported, not just in `.env` |
|
||
| Windows SmartScreen warning | Sign with EV cert, or users right-click → "Run anyway" |
|
||
| Smoke test fails with port-in-use | Stop any local dev server on 20128 before running `electron:smoke:packaged` |
