Chatway Integration Guide

A complete guide for integrating Chatway chat widgets into Next.js applications.

Overview

This guide documents the proper way to integrate Chatway chat widgets into Next.js sites, including common pitfalls and the correct implementation pattern.

✅ Working Implementation

Step 1: Create `pages/_document.tsx`

Create or modify your pages/_document.tsx file with this exact code:

import { Html, Head, Main, NextScript } from 'next/document'
 
export default function Document() {
  return (
    <Html lang="en">
      <Head>
        <script
          id="chatway"
          async
          src="https://cdn.chatway.app/widget.js?id=6qxBzuIMeu2h"
        />
      </Head>
      <body>
        <Main />
        <NextScript />
      </body>
    </Html>
  )
}

Step 2: Clear Cache (If Needed)

If you experience refresh loops or build issues:

rm -rf .next
npm run dev

Key Learning Points

✅ Correct Approaches

Use regular <script> tags in _document.tsx - NOT the Next.js Script component
Place in <Head> section of the document, not in components or theme configs
Clear .next cache if you get stuck in refresh loops
Widget loads site-wide with this approach

❌ Common Mistakes

Don't use Script component in _document.tsx (causes issues)
Don't put scripts in theme configs or other components for global widgets
Don't use next/head for external widget scripts

Chatway Integration Prompt

I need to integrate a Chatway chat widget into my Next.js site. The widget should appear on all pages with a preview bubble and welcome message.

Requirements:

Use Chatway widget ID: 6qxBzuIMeu2h (or replace with your own)
Follow Next.js best practices (no console warnings)
Load on all pages
Should not cause refresh loops

Implementation:

Create a pages/_document.tsx file with this exact code:

import { Html, Head, Main, NextScript } from 'next/document'
 
export default function Document() {
  return (
    <Html lang="en">
      <Head>
        <script
          id="chatway"
          async
          src="https://cdn.chatway.app/widget.js?id=6qxBzuIMeu2h"
        />
      </Head>
      <body>
        <Main />
        <NextScript />
      </body>
    </Html>
  )
}

Important Notes:

Use regular <script> tag in _document.tsx Head section (NOT Next.js Script component)
If you get refresh loops, run: rm -rf .next then restart dev server
The widget will appear site-wide with the configured preview message
Perfect for support contexts - consider customizing the preview message

Troubleshooting:

If you see Next.js script warnings, make sure you're using regular <script> not Script component
Clear .next cache if the page keeps refreshing
Widget should load asynchronously without blocking page rendering

Troubleshooting

Common Issues and Solutions

Issue: "Do not add script tags using next/head" warning

Solution: Make sure you're using regular <script> in _document.tsx, not Script component

Issue: Page keeps refreshing in development

Solution: Clear build cache with rm -rf .next and restart dev server

Issue: Widget not appearing

Solution: Check that widget ID is correct and Chatway account is properly configured

Issue: Widget appears but preview bubble doesn't show
