Integrating the Code

After installing the library, it's time to integrate the chat widget into your Next.js project. Here's how to do it step-by-step:

Step 1: Import the Required Modules

Start by importing the necessary modules from Next.js and the Predictable Dialogs library. This includes the Standard component, which is a versatile chat widget type. Instead of Standard component, you could also select Bubble or Popup. You can read here to learn more about the widget types and their customization options.

'use client'
import { Standard } from '@agent-embed/nextjs'
  • "use client": Ensures the component is rendered on the client side, necessary for interactive widgets.

  apiHost={'https://app.predictabledialogs.com/web/incoming'}
  agentName={'Assistant OpenAI-18452'}
  initialPrompt={'Hi'}

  filterResponse={function (response) {
    const annotationRegex = /【\d+:\d+†[^\s】]+】/g
    return response.replace(annotationRegex, '')
  }}
/>

Code Breakdown:

  • id="Demo": Sets the unique identifier for this instance of the chatbot.
