<p>On the <a href="/concepts-publish">Publish pane</a>, the <strong>Embed into site</strong> tab displays code that can be inserted in the <code><body></code> of your HTML to interact with your flow.</p>
|
||
<p>The chat widget is implemented as a web component called <code>langflow-chat</code> and is loaded from a CDN. For more information, see the <a href="https://github.com/langflow-ai/langflow-embedded-chat" target="_blank" rel="noopener noreferrer">langflow-embedded-chat repository</a>.</p>
|
||
<p>For a sandbox example, see the <a href="https://codesandbox.io/p/sandbox/langflow-embedded-chat-example-dv9zpx" target="_blank" rel="noopener noreferrer">Langflow embedded chat CodeSandbox</a>.</p>
|
||
<p>The following example includes the minimum required inputs, called <a href="https://react.dev/learn/passing-props-to-a-component" target="_blank" rel="noopener noreferrer">props</a> in React, for using the chat widget in your HTML code, which are <code>host_url</code> and <code>flow_id</code>.
|
||
The <code>host_url</code> value must be <code>HTTPS</code>, and may not include a <code>/</code> after the URL.
|
||
The <code>flow_id</code> value is found in your Langflow URL.
|
||
For a Langflow server running the <a href="/basic-prompting">Basic prompting flow</a> at <code>https://c822-73-64-93-151.ngrok-free.app/flow/dcbed533-859f-4b99-b1f5-16fce884f28f</code>, your chat widget code is similar to the following:</p>

<p>The chat widget requires your flow to contain <strong>Chat Input</strong> and <strong>Chat Output</strong> components for the widget to communicate with it.
|
||
Sending a message to Langflow without a <strong>Chat Input</strong> still triggers the flow, but the LLM warns you the message is empty.
|
||
<strong>Text Input</strong> and <strong>Text Output</strong> components can send and receive messages with Langflow, but without the ongoing LLM "chat" context.</p>
