# CoreTraffic

CoreTraffic is the serve.zone ingress component that receives routing updates from Coreflow and applies them to `@push.rocks/smartproxy`. It runs as a small TypeScript service inside the cluster and keeps HTTP redirects, HTTPS termination, backend routing, default response headers, and optional basic authentication in sync with the control plane.

## Issue Reporting and Security

For reporting bugs, issues, or security vulnerabilities, please visit [community.foss.global/](https://community.foss.global/). This is the central community hub for all issue reporting. Developers who sign and comply with our contribution agreement and go through identification can also get a [code.foss.global/](https://code.foss.global/) account to submit Pull Requests directly.

## What It Does

CoreTraffic is intentionally focused:

- Starts a `SmartProxy` instance for cluster ingress.
- Connects to Coreflow over `@api.global/typedsocket`.
- Registers the `updateRouting` typed request handler.
- Converts `IReverseProxyConfig[]` updates into SmartProxy route configs.
- Adds an HTTP-to-HTTPS redirect route on port `7999`.
- Adds HTTPS reverse-proxy routes on port `8000` with per-domain certificates.
- Adds the `servezone_coretraffic_version` response header to managed routes.

## Runtime Flow

```text
Coreflow
  -> TypedSocket updateRouting
  -> CoreflowConnector
  -> CoretrafficTaskManager buffered setupRouting task
  -> SmartProxy.updateRoutes(...)
```

Routing updates are buffered so fast repeated changes collapse into the most recent route state instead of overwhelming the proxy engine.

## Usage

```typescript
import { CoreTraffic } from 'coretraffic';

const coreTraffic = new CoreTraffic();
await coreTraffic.start();

// later
await coreTraffic.stop();
```

In production, CoreTraffic is normally started through `runCli()` and expects Coreflow to be reachable at `http://coreflow:3000`.

## Routing Input

CoreTraffic consumes `@tsclass/tsclass` reverse proxy configs:

```typescript
const reverseConfig = {
  hostName: 'app.example.com',
  destinationIps: ['10.0.0.10'],
  destinationPorts: [3000],
  privateKey: '-----BEGIN PRIVATE KEY-----...',
  publicKey: '-----BEGIN CERTIFICATE-----...',
  authentication: {
    type: 'Basic',
    user: 'admin',
    pass: 'secret',
  },
};
```

Each config becomes one HTTPS SmartProxy route with TLS termination and one or more backend targets generated from the destination IP/port combinations.

## Development

Install dependencies with pnpm:

```bash
pnpm install
```

Build TypeScript:

```bash
pnpm run build
```

Run tests:

```bash
pnpm test
```

Check outdated dependencies:

```bash
pnpm outdated
```

## Important Dependencies

- `@push.rocks/smartproxy`: route-based proxy engine used for redirects, TLS termination, and forwarding.
- `@api.global/typedsocket`: Coreflow connection transport.
- `@api.global/typedrequest`: typed RPC handler registration.
- `@serve.zone/interfaces`: typed Coreflow/CoreTraffic routing request contract.
- `@push.rocks/taskbuffer`: buffered routing update execution.
