Javascript library to display flowise chatbot on your website
Install:
yarn install
Dev:
yarn dev
A development server will be running on http://localhost:5678 automatically. Update public/index.html to connect directly to Flowise:
<!-- public/index.html -->
<script type="module">
import Chatbot from 'https://localhost:5678/web.js'; // Change to from './web.js' to 'https://localhost:5678/web.js'
Chatbot.init({
chatflowid: '91e9c803-5169-4db9-8207-3c0915d71c5f', // Add your Flowise chatflowid
apiHost: 'https://your-flowise-instance.com', // Add your Flowise apiHost
});
</script>
Build:
yarn build
<script type="module">
import Chatbot from 'https://cdn.jsdelivr.net/npm/flowise-embed/dist/web.js';
Chatbot.init({
chatflowid: '<chatflowid>',
apiHost: 'http://localhost:3000',
});
</script>
<script type="module">
import Chatbot from 'https://cdn.jsdelivr.net/npm/flowise-embed/dist/web.js';
Chatbot.initFull({
chatflowid: '<chatflowid>',
apiHost: 'http://localhost:3000',
});
</script>
<flowise-fullchatbot></flowise-fullchatbot>
To enable full screen, add margin: 0 to body style, and confirm you don't set height and width
<body style="margin: 0">
<script type="module">
import Chatbot from 'https://cdn.jsdelivr.net/npm/flowise-embed/dist/web.js';
Chatbot.initFull({
chatflowid: '<chatflowid>',
apiHost: 'http://localhost:3000',
theme: {
chatWindow: {
// height: 700, don't set height
// width: 400, don't set width
},
},
});
</script>
</body>
You can also customize chatbot with different configuration
<script type="module">
import Chatbot from 'https://cdn.jsdelivr.net/npm/flowise-embed/dist/web.js';
Chatbot.init({
chatflowid: '91e9c803-5169-4db9-8207-3c0915d71c5f',

The Flowise Embed Proxy Server enhances the security of your chatbot implementation by acting as a protective intermediary layer. This server eliminates the need to expose sensitive Flowise instance details in your frontend code and provides several key security benefits:
This proxy server can be deployed to any Node.js hosting platform.
# Copy .env.example to .env and configure required settings:
API_HOST=https://your-flowise-instance.com
FLOWISE_API_KEY=your-api-key
# Configure your chatflows:
# Format: [identifier]=[chatflowId],[allowedDomain1],[allowedDomain2],...
#
# identifier: Any name you choose (e.g., agent1, support, salesbot)
# chatflowId: The UUID of your Flowise chatflow
# allowedDomains: Comma-separated list of domains where this chat can be embedded
#
# Examples:
support=abc123-def456,https://example.com
agent1=xyz789-uvw456,https://sales.example.com
helpdesk=ghi123-jkl456,https://help.example.com,https://support.example.com
yarn install yet)yarn install
yarn start
# Server will be available at:
# - Local: http://localhost:3001
# - Cloud: [Your Platform URL] (e.g., https://your-app.herokuapp.com)
<script type="module">
import Chatbot from 'your-proxy-server-url/web.js'; // Must be 'your-proxy-server-url/web.js'
Chatbot.init({
chatflowid: 'your-identifier-here', // Must match an identifier from your .env
apiHost: 'your-proxy-server-url', // Must match the URL of your proxy server
chatflowConfig: {
// ...
},
});
</script>
<!-- public/index.html -->
chatflowid: 'your-identifier-here' // Must match an identifier from your .env
Important Notes:
When deploying to cloud platforms, you must configure the environment variables directly in your platform. The proxy server will not start without these variables being properly set. Compatible with Nixpacks for automatic deployment configuration.
Configure your environment variables (see above)
Start the proxy server:
yarn start
# Server will be available at:
# - Local: http://localhost:3001
public/index.html in your code editorchatflowid and apiHost to match your .env settings:<!-- public/index.html -->
<script type="module">
import Chatbot from './web.js';
Chatbot.init({
chatflowid: 'agent1', // Must match an identifier from your .env
apiHost: 'http://localhost:3001', // Change this from window.location.origin to 'http://localhost:3001'
});
</script>
For full page testing, use this configuration instead:
<!-- public/index.html -->
<flowise-fullchatbot></flowise-fullchatbot>
<script type="module">
import Chatbot from './web.js';
Chatbot.initFull({
chatflowid: 'agent1', // Must match an identifier from your .env
apiHost: 'http://localhost:3001', // Change this from window.location.origin to 'http://localhost:3001'
});
</script>
yarn dev
# This will serve the test page on http://localhost:5678 automatically
Note: The development URL (http://localhost:5678) is automatically added to allowed domains in development mode. You don't need to add it manually.
