packages/@n8n/nodes-langchain/nodes/trigger/ChatTrigger/README.md
This guide explains how to set up local development for the ChatTrigger node when working with the chat bundle.
Since the chat bundle is loaded via <script type="module">, it needs to be served over HTTPS for local development.
Install the http-server globally:
npm install -g http-server
Generate a self-signed certificate for HTTPS:
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
Navigate to the chat package and build it:
cd packages/frontend/@n8n/chat && pnpm run build
Run the HTTPS server to serve the chat bundle:
http-server packages/frontend/@n8n/chat/dist -g -S -C cert.pem -K key.pem --port 8443 --cors
Modify the import paths in templates.ts to point to your local server:
<script type="module">
import { createChat } from 'https://127.0.0.1:8443/chat.bundle.es.js';
