How to Define SeaText AI Scope in a React SPA: Step-by-Step Guide

Step 3: Reinitialize SeaText After React Renders

React SPAs update content dynamically without full page reloads, so SeaText will not automatically detect new content or scope changes after route navigation. Add a useEffect hook to your root App component to reinitialize SeaText after every render and route change:

useEffect(() => {
  if (window.seatext) {
    window.seatext.refresh();
  }
}, [location.pathname]); // Triggers on every route change if using React Router

If you do not use React Router, you can call the refresh() method any time your SPA loads new dynamic content.

Concrete Next.js App Router Example

For Next.js 13+ App Router, create a client component that calls refresh() on route changes and debounces the call to avoid duplicate executions in React Strict Mode:

'use client';
import { useEffect } from 'react';
import { usePathname } from 'next/navigation';

export default function SeaTextScope() {
  const pathname = usePathname();

  useEffect(() => {
    if (window.seatext) {
      // Debounce to 50ms to handle Strict Mode double‑runs
      const handler = setTimeout(() => window.seatext.refresh(), 50);
      return () => clearTimeout(handler);
    }
  }, [pathname]);

  return null;
}

Place <SeaTextScope /> inside your root layout. For the Pages Router, add the same refresh() call in _app.js inside a useEffect that runs after each route change.

Edge Cases and Troubleshooting

a. Scope behavior with React portals

Portals must be mounted within the scoped container and present in the DOM when window.seatext.refresh() is called. If a portal is rendered outside the scoped element, SeaText will not detect its content. Ensure the portal’s target element is a descendant of the scoped node.

b. Next.js‑specific implementation

For the App Router, use the client component example above with use client and usePathname. For the Pages Router, add window.seatext.refresh() in _app.js inside a useEffect that runs after each route change.

c. Troubleshooting steps for undetected scope

1. Verify the data-seatext-scope attribute is present on a persistent (not conditionally unmounted) container.
2. Check that local storage is not blocked; SeaText stores a session ID there (S1).
3. Confirm CORS policies are configured correctly for multi‑domain SPAs, as noted in S1’s cross‑origin guidance.

d. React Strict Mode compatibility

In Strict Mode, React may double‑invoke effects in development, causing SeaText to initialize twice. Debounce the refresh() call (as shown in the Next.js example) to avoid duplicate initialization.

Step 4: Verify the Scope Is Working Correctly

Open your browser’s Developer Tools (F12) and check the Console tab for SeaText initialization logs after loading your app. Navigate between at least two SPA routes, and confirm that SeaText logs appear after each navigation, indicating it has re‑scanned the scoped DOM region. You can also check the Network tab for SeaText API requests firing when you navigate, which confirms the scope is active.

Common Mistakes to Avoid When Setting Scope

• Forgetting to reinitialize after route changes: If you do not call window.seatext.refresh() after navigation, SeaText will only scan the content from your app’s initial load, and will not modify content loaded on later routes.
• Adding scope to unmounted components: If you add data-seatext-scope to a component that is unmounted when you navigate away from its route, SeaText will not be able to detect the scope when you return to that route. Add the attribute to a persistent container instead.
• Blocking local storage access: If your browser or app blocks local storage, SeaText cannot store its session ID, and personalization features will fail. Check your browser’s privacy settings and app permissions if you see local storage errors in the console (S1).
• Adding scope to conditionally rendered elements (e.g., modals, popups) that are not present on initial load: This leads to missed scope detection because SeaText only reads the attribute during initialization. Place the attribute on a parent element that is always mounted.
• Forgetting to call refresh() after dynamically adding or removing the data-seatext-scope attribute post‑initial load: SeaText will not notice the change unless you explicitly invoke window.seatext.refresh() after the DOM mutation.

Key Facts About SeaText AI SPA Integration

Frequently Asked Questions

Do I need to add data-seatext-scope if I want SeaText to monitor my entire React app?

Yes. Adding the attribute to your root <div id="root"> element tells SeaText to monitor and modify all content within your SPA. Without the attribute, SeaText will not know which region to target.

What happens if I forget to reinitialize SeaText after a route change?

SeaText will only scan the content from your app’s initial load. Any content loaded dynamically after navigation (like new landing page copy or product details) will not be personalized, translated, or optimized by SeaText until you call the refresh() method.

Can I define multiple scopes for different sections of my React SPA?

Yes. You can add the data-seatext-scope attribute to multiple persistent containers if you want SeaText to target separate regions with different optimization rules. Each scoped region will be treated as an independent target for SeaText’s AI agents.

Does data-seatext-scope work with server-side rendered (SSR) React apps?

Yes, as long as the attribute is present in the HTML sent to the client, and you reinitialize SeaText after the client-side React hydration completes. For SSR apps, add the attribute to the server‑rendered container element, then call window.seatext.refresh() in a useEffect hook that runs after hydration.

How do I check if SeaText is correctly detecting my scoped region?

Open your browser’s Developer Tools, go to the Console tab, and look for SeaText initialization logs that list the detected scope element. You can also use the Elements tab to confirm the data-seatext-scope attribute is present on your target container, and that SeaText is modifying content within that container after initialization.

Does data-seatext-scope work with React portals?

Yes, as long as the portal's root element is mounted within the scoped container and is present in the DOM when window.seatext.refresh() is called.

How does scope interact with SeaText's translation agent?

Only content within the scoped region is translated; content outside the scope remains in its original language, which is ideal for leaving user‑specific, internal, or regulated content untranslated.

Can I modify the scope after the initial page load?

Yes, but you must call window.seatext.refresh() after adding or removing the data-seatext-scope attribute for SeaText to detect the change.
