This commit modifies the audio download process in `whatsapp-router/src/webhook.ts` to align with the updated nucleo-whatsapp API. Previously, audio files were downloaded using a direct GET request to the file URL. This has been changed to a POST request to the `/downloadFileWithCredentials` endpoint provided by nucleo-whatsapp. Key changes: - Audio files are now downloaded by POSTing to `[OPEN_WA_URL]/downloadFileWithCredentials` with the audio file's URL in the request body. - The `/downloadFileWithCredentials` endpoint returns a base64 encoded string directly, so the explicit base64 conversion step after downloading has been removed. This change ensures compatibility with the correct API for fetching message media.
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 four containers:
- openwa – provides access to WhatsApp through the open-wa project.
- whatsapp-router – receives webhook events from openwa and forwards messages to a conversation handler. Handlers can be configured per chat ID in
whatsapp-router/src/chatHandlers.ts. - chat-ui – simple web chat interface that also communicates with the LLM agent.
- conversation-layer-agent – lightweight agent that uses the Gemini SDK to answer questions about this repository.
All services can be launched together with docker-compose.
Usage
- Configure the URL of your LLM agent in
docker-compose.yml(LLM_AGENT_URL). - Set your Gemini API key in
.env(GEMINI_API_KEY) so the conversation-layer-agent can use the Gemini SDK. - Optionally edit
whatsapp-router/src/chatHandlers.tsto map specific chat IDs to different handler URLs or local handlers. By default the chat ID50498554225@c.usis mapped to a built‑in HelloWorld agent for testing andrepo-helper@c.ustalks to the conversation-layer-agent. - Run:
docker-compose up --build
The chat UI will be available on http://localhost:3000. Open-wa exposes its API on port 8080 and the WhatsApp router listens on port 3001.
Alternatively you can run the chat UI and router locally using Make:
make chat # start chat-ui
make router # start whatsapp-router
make agent # start conversation-layer-agent
Both targets read configuration from a .env file if it exists (see .env.example).
