## Development Setup

### Prerequisites

- **macOS** (development machine): Node.js 20+, npm
- **Linux server** (`192.168.1.228`): Rust toolchain, Podman, Nginx, Debian 12
- SSH key: `~/.ssh/archipelago-deploy`

### Local Frontend Development

```bash
cd neode-ui
npm install
npm start         # Vite dev server on :8100, mock backend on :5959
```

The dev server at `http://localhost:8100` uses a mock backend. Login with `password123`.

### Deploying Changes

**Never build Rust on macOS.** The deploy script rsyncs source to the Linux server and builds there.

```bash
# Deploy to live server (builds backend + frontend, restarts services)
./scripts/deploy-to-target.sh --live

# Deploy to both servers
./scripts/deploy-to-target.sh --both
```

The deploy script:
1. Rsyncs source to the server
2. Builds Rust backend on the server (`cargo build --release`)
3. Builds Vue frontend (`npm run build`)
4. Copies artifacts to production paths
5. Restarts the `archipelago` systemd service
6. Runs a health check

### Running Tests

```bash
# Frontend tests
cd neode-ui && npm test

# Backend tests (on dev server via SSH)
ssh -i ~/.ssh/archipelago-deploy archipelago@192.168.1.228 \
  "cd ~/archy/core && cargo test --all-features"

# Both
./scripts/run-tests.sh
```

## Adding a New RPC Endpoint

### 1. Create the Handler

Add a handler method in the appropriate file under `core/archipelago/src/api/rpc/`. If no existing file fits, create a new one.

```rust
// core/archipelago/src/api/rpc/mymodule.rs
use super::RpcHandler;
use anyhow::Result;

impl RpcHandler {
    /// mymodule.action — description of what it does.
    pub(super) async fn handle_mymodule_action(
        &self,
        params: Option<serde_json::Value>,
    ) -> Result<serde_json::Value> {
        let params = params.ok_or_else(|| anyhow::anyhow!("Missing params"))?;
        let name = params
            .get("name")
            .and_then(|v| v.as_str())
            .ok_or_else(|| anyhow::anyhow!("Missing required parameter: name"))?;

        // Your logic here
        let result = do_something(name).await?;

        Ok(serde_json::json!({ "ok": true, "result": result }))
    }
}
```

**Key patterns:**
- Handlers are `pub(super)` — visible only to the RPC router
- Accept `Option<serde_json::Value>` for params (omit for parameterless endpoints)
- Return `Result<serde_json::Value>`
- Use `self.config.data_dir` for data persistence
- Use `anyhow::bail!()` for error responses

### 2. Register the Route

Add the module declaration and route in `core/archipelago/src/api/rpc/mod.rs`:

```rust
// At the top:
mod mymodule;

// In the match statement (handle_rpc_call):
"mymodule.action" => self.handle_mymodule_action(params).await,
```

### 3. Add Module (if new)

If your logic warrants a separate module:

```rust
// core/archipelago/src/main.rs
mod mymodule;  // Add to module declarations
```

### 4. Frontend Client

Add a convenience method to `neode-ui/src/api/rpc-client.ts`:

```typescript
async myAction(params: { name: string }): Promise<{ ok: boolean; result: string }> {
  return this.call({
    method: 'mymodule.action',
    params,
  })
}
```

### 5. Deploy and Test

```bash
./scripts/deploy-to-target.sh --live
curl -X POST http://192.168.1.228/rpc/v1 \
  -H "Content-Type: application/json" \
  -b "archipelago_session=YOUR_SESSION" \
  -d '{"method":"mymodule.action","params":{"name":"test"}}'
```

## Adding a New Vue Page

### 1. Create the Component

```vue
<!-- neode-ui/src/views/MyPage.vue -->
<template>
  <div>
    <h1 class="text-4xl font-bold text-white mb-2">My Page</h1>
    <div class="glass-card p-6">
      <!-- Content here -->
    </div>
  </div>
</template>

<script setup lang="ts">
import { ref, onMounted } from 'vue'
import { rpcClient } from '@/api/rpc-client'

// State and logic
</script>
```

### 2. Add the Route

In `neode-ui/src/router/index.ts`, add inside the dashboard children:

```typescript
{
  path: 'my-page',
  name: 'my-page',
  component: () => import('@/views/MyPage.vue'),
},
```

### 3. Standards

- Always use `<script setup lang="ts">` — never Options API
- Use `glass-card` for containers, `bg-white/5 rounded-lg` for sub-rows
- Create global CSS classes in `src/style.css` instead of inline Tailwind
- Use `rpcClient` from `@/api/rpc-client.ts` for all backend calls
- Handle loading states and errors for all async operations

## Writing Tests

### Frontend (Vitest)

```typescript
// neode-ui/src/api/__tests__/my-test.test.ts
import { describe, it, expect, vi, beforeEach } from 'vitest'

describe('MyFeature', () => {
  beforeEach(() => {
    vi.restoreAllMocks()
  })

  it('should do something', async () => {
    vi.stubGlobal('fetch', vi.fn().mockResolvedValue({
      ok: true,
      json: () => Promise.resolve({ result: 'ok' }),
    }))

    // Test your logic
    expect(true).toBe(true)
  })
})
```

### Backend (Rust)

```rust
#[cfg(test)]
mod tests {
    use super::*;
    use tempfile::tempdir;

    #[tokio::test]
    async fn test_my_function() {
        let dir = tempdir().unwrap();
        let result = my_function(dir.path()).await.unwrap();
        assert_eq!(result, expected);
    }
}
```

## Code Quality Checklist

- [ ] TypeScript strict mode: no `any`, use `unknown` or proper types
- [ ] No `unwrap()` or `expect()` in production Rust code — use `?`
- [ ] No `console.log` — wrap in `if (import.meta.env.DEV)`
- [ ] No empty catch blocks — log or handle errors
- [ ] Functions under 50 lines
- [ ] `cargo clippy` and `cargo fmt` pass
- [ ] `npx vue-tsc --noEmit` passes
- [ ] Security: validate all inputs, no command injection
- [ ] Container security: readonly_root, no_new_privileges, non-root user
