# ChatTrigger Local Development
This guide explains how to set up local development for the ChatTrigger node when working with the chat bundle.
## Prerequisites
Since the chat bundle is loaded via `<script type="module">`, it needs to be served over HTTPS for local development.
## Setup Instructions
### 1. Install HTTP Server
Install the http-server globally:
```bash
npm install -g http-server
```
### 2. Generate SSL Certificate
Generate a self-signed certificate for HTTPS:
```bash
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes
```
### 3. Build the Chat Bundle
Navigate to the chat package and build it:
```bash
cd packages/frontend/@n8n/chat && pnpm run build
```
### 4. Start HTTPS Server
Run the HTTPS server to serve the chat bundle:
```bash
http-server packages/frontend/@n8n/chat/dist -g -S -C cert.pem -K key.pem --port 8443 --cors
```
### 5. Update Import Paths
Modify the import paths in `templates.ts` to point to your local server:
```html
<script type="module">
import { createChat } from 'https://127.0.0.1:8443/chat.bundle.es.js';
```
```html
<link href="https://127.0.0.1:8443/chat.css" rel="stylesheet" />
```
