google-labs-jules[bot] e0ff27aa31 feat: Initial Docker Compose setup for conversation layer
Adds a docker-compose.yml to manage the OpenWA, Chat UI, and WhatsApp Router services.

Includes:
- Dockerfile and basic Node.js skeleton for Chat UI.
- Dockerfile and basic Node.js skeleton for WhatsApp Router.
- docker-compose.yml defining the three services, including:
    - Placeholder for OpenWA image (you must configure this).
    - Build contexts for UI and router.
    - Port mappings.
    - Environment variable examples.
    - Volume for OpenWA session persistence.
- Updated README.md with detailed setup, configuration, and usage instructions.

# conversation-layer
## Conversation Layer System
This repository contains the services for the conversation layer, managed by Docker Compose. It includes:
* **OpenWA:** Handles WhatsApp communication.
* **Chat UI:** Provides a user interface for conversations.
* **WhatsApp Router:** Connects OpenWA to the Chat UI and an LLM agent.
## Prerequisites
* Docker (https://www.docker.com/get-started)
* Docker Compose (usually included with Docker Desktop)
## Setup and Running
1. **Clone the repository:**
```bash
git clone <your-repo-url>
cd <your-repo-directory>
```
2. **Configure OpenWA:**
* Open the `docker-compose.yml` file.
* **Crucial:** Locate the `openwa` service definition. You may need to replace the placeholder image `image: devlikeapro/open-wa-api:latest` with the specific OpenWA Docker image you intend to use.
* Consult the documentation for your chosen OpenWA image to set necessary environment variables under `services.openwa.environment`. For example, you'll likely need to configure the `WEBHOOK_URL` that OpenWA should call. The `whatsapp-router` service expects this webhook at `http://whatsapp-router:3001/webhook`. So, an example for OpenWA's configuration might be `WEBHOOK_URL=http://whatsapp-router:3001/webhook`.
* Adjust port mappings for `openwa` if your image uses different ports than the defaults provided (API `8080`, Webhook `3000`).
3. **Configure Service Endpoints (if necessary):**
* **Chat UI (`chat-ui` service):** If the Chat UI needs to know the endpoint of your LLM agent, set the `LLM_AGENT_URL` (or similar) environment variable in `docker-compose.yml` under `services.chat-ui.environment`.
* **WhatsApp Router (`whatsapp-router` service):** This service is pre-configured to look for OpenWA at `http://openwa:8080`. If your LLM agent is called by the router, set its URL via an environment variable like `LLM_AGENT_URL` under `services.whatsapp-router.environment`.
4. **Build and run the services:**
```bash
docker-compose up --build
```
* The `--build` flag ensures images are built if they don't exist or if Dockerfiles/contexts have changed.
* To run in detached mode (in the background), use `docker-compose up -d --build`.
5. **Accessing Services:**
* **OpenWA API:** Typically `http://localhost:8080` (or the host port you mapped).
* **WhatsApp Router:** `http://localhost:3001` (its webhook is at `http://localhost:3001/webhook`, but this is for OpenWA to call internally).
* **Chat UI:** `http://localhost:3002`.
6. **Initial OpenWA Setup:**
* After starting, OpenWA will likely require you to scan a QR code with your WhatsApp mobile app to link it. Check the logs of the `openwa` service for the QR code or instructions:
```bash
docker-compose logs openwa
```
* Session data for OpenWA is stored in a Docker volume named `openwa_data` to persist the session across restarts.
7. **Stopping the services:**
```bash
docker-compose down
```
* To remove volumes (like `openwa_data`, which will clear the session), use `docker-compose down -v`.
