# Conversation Layer

This module contains the services that handle messaging for WhatsApp and the web chat interface. All source code is now written in **TypeScript**. It is composed of three containers:

- **openwa** – provides access to WhatsApp through the [open-wa](https://github.com/open-wa/wa-automate-nodejs) project.
- **whatsapp-router** – receives webhook events from openwa and forwards messages to an external LLM agent.
- **chat-ui** – simple web chat interface that also communicates with the LLM agent.

All services can be launched together with `docker-compose`.

## Usage

1. Configure the URL of your LLM agent in `docker-compose.yml` (`LLM_AGENT_URL`).
2. Run:

```bash
docker-compose up --build
```

The chat UI will be available on [http://localhost:3000](http://localhost:3000). Open-wa exposes its API on port `8080` and the WhatsApp router listens on port `3001`.
