Implementing the OpenAI Assistant in HTML

Adding an OpenAI Assistant chatbot to your HTML website is remarkably straightforward. The entire implementation requires just a few lines of code, which we'll break down step by step.

The Complete HTML Implementation

Here's the full code snippet that adds a Predictable Dialogs chat widget to a basic HTML page:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Standard Example</title>
  </head>
  <body>
    <h1>Welcome to the Standard Agent Example!</h1>
    <p>
      This is a basic HTML page with a standard chat agent embedded dynamically using JavaScript.
    </p>
    <script type="module">
      import Agent from 'https://cdn.jsdelivr.net/npm/@agent-embed/js/dist/web.js'
      Agent.initStandard({
        agentName: 'Assistant OpenAI-18452', // Generated on the predictable dialogs app
        apiHost: 'https://app.predictabledialogs.com/web/incoming',
      })
    </script>
    <agent-standard style="width: 100%; height: 600px; "></agent-standard>
  </body>
</html>

Code Breakdown

Let's examine the key components of this implementation:

  1. Script Import and Initialization:

    import Agent from 'https://cdn.jsdelivr.net/npm/@agent-embed/js/dist/web.js'
Agent.initStandard({
  agentName: 'Assistant OpenAI-18452',
  apiHost: 'https://app.predictabledialogs.com/web/incoming',
})

    This code imports the Predictable Dialogs JavaScript library directly from a CDN, eliminating the need for package managers or build tools. The Agent.initStandard() function initializes a standard chat widget with basic configuration.

  2. Widget Placement:

    <agent-standard style="width: 100%; height: 600px; "></agent-standard>

    This custom HTML element defines where the chat widget will appear on your page and sets its dimensions. The element is automatically enhanced by the Predictable Dialogs library to display a fully functional chat interface.

Configuration Parameters Explained

The Agent.initStandard() function accepts several configuration parameters:

  • agentName: The identifier for your OpenAI Assistant as configured in the Predictable Dialogs dashboard
  • apiHost: The endpoint that processes messages and communicates with the OpenAI API

Understanding the Integration Architecture

The implementation creates a seamless communication flow:

  1. The user interacts with the chat widget on your HTML page
  2. User messages are sent to the Predictable Dialogs backend
  3. The backend communicates with the appropriate OpenAI Assistant
  4. The AI generates a response, which is returned to your webpage
  5. The conversation continues within your website's interface

This architecture handles all the complexities of session management, API communication, and response processing behind the scenes.

Customization Options

One of the standout features of Predictable Dialogs is the extensive customization available. You can easily enhance the basic implementation with additional options:
