# Toes - Claude Code Guide

## What It Is

Personal web appliance that auto-discovers and runs multiple web apps on your home network.

"Plug it in, turn it on, and forget about the cloud."

## How It Works

1. Host server scans `/apps` directory for valid apps
2. Valid app = has `package.json` with `scripts.toes` entry
3. Each app spawned as child process with unique port (3001+)
4. Dashboard UI shows all apps with current status, logs, and links

## Key Files

### Server (`src/server/`)
- `apps.ts` - **The heart**: app discovery, process management, health checks, auto-restart
- `api/apps.ts` - REST API for app lifecycle (start/stop/restart, logs, icons, rename)
- `api/sync.ts` - File sync protocol (manifest, push/pull, watch)
- `index.tsx` - Entry point (minimal, initializes Hype)
- `shell.tsx` - HTML shell for web UI

### Client (`src/client/`)
- `components/` - Dashboard, Sidebar, AppDetail, Nav
- `modals/` - NewApp, RenameApp, DeleteApp dialogs
- `styles/` - Forge CSS-in-JS (themes, buttons, forms, layout)
- `state.ts` - Client state management
- `api.ts` - API client

### CLI (`src/cli/`)
- `commands/manage.ts` - list, start, stop, restart, info, new, rename, delete, open
- `commands/sync.ts` - push, pull, sync
- `commands/logs.ts` - log viewing with tail support

### Shared (`src/shared/`)
- Code shared between frontend (browser) and backend (server)
- `types.ts` - App, AppState, Manifest interfaces
- IMPORTANT: Cannot use filesystem or Node APIs (runs in browser)

### Lib (`src/lib/`)
- Code shared between CLI and server (server-side only)
- `templates.ts` - Template generation for new apps
- Can use filesystem and Node APIs (never runs in browser)

### Other
- `apps/*/package.json` - Must have `"toes": "bun run --watch index.tsx"` script
- `TODO.txt` - Task list

## Tech Stack

- **Bun** runtime (not Node)
- **Hype** (custom HTTP framework wrapping Hono) from git+https://git.nose.space/defunkt/hype
- **Forge** (typed CSS-in-JS) from git+https://git.nose.space/defunkt/forge
- **Commander** + **kleur** for CLI
- TypeScript + Hono JSX

## Running

```bash
bun run --hot src/server/index.tsx  # Dev mode with hot reload
```

## App Structure

```tsx
// apps/example/index.tsx
import { Hype } from "@because/hype"
const app = new Hype()
app.get("/", (c) => c.html(<h1>Content</h1>))
export default app.defaults
```

## Conventions

- Apps get `PORT` env var from host
- Each app is isolated process with own dependencies
- No path-based routing - apps run on separate ports
- `DATA_DIR` env controls where apps are discovered
- Path aliases: `$` → server, `@` → shared, `%` → lib

## Current State

### Infrastructure (Complete)
- App discovery, spawn, watch, auto-restart with exponential backoff
- Health checks every 30s (3 failures trigger restart)
- Port pool (3001-3100), sticky allocation per app
- SSE streams for real-time app state and log updates
- File sync protocol with hash-based manifests

### CLI
- Full management: `toes list|start|stop|restart|info|new|rename|delete|open`
- File sync: `toes push|pull|sync`
- Logs: `toes logs [-f] <app>`

Check `TODO.txt` for planned features

## Coding Guidelines

TS files should be organized in the following way:

- imports
- re-exports
- const/lets
- enums
- interfaces
- types
- classes
- functions
- module init (top level function calls)

In each section, put the `export`s first, in alphabetical order.

Then, after the `export`s (if there were any), put everything else,
also in alphabetical order.

For single-line functions, use `const fn = () => {}` and put them in the
"functions" section of the file.

All other functions use the `function blah(){}` format.

Example:

```ts
import { code } from "coders"
import { something } from "somewhere"

export type { SomeType }

const RETRY_TIMES = 5
const WIDTH = 480

enum State {
  Stopped,
  Starting,
  Running,
}

interface Config {
  name: string
  port: number
}

type Handler = (req: Request) => Response

class App {
  config: Config

  constructor(config: Config) {
    this.config = config
  }
}

const isApp = (name: string) =>
  apps.has(name)

function createApp(name: string): App {
  const app = new App({ name, port: 3000 })
  apps.set(name, app)
  return app
}

function start(app: App): void {
  console.log(`Starting ${app.config.name}`)
}
```
