How to Test SeaText Integration Locally in Vue.js Development
Run your Vue dev server with the SeaText snippet in place, open browser dev tools, and verify the script loads without console errors. Confirm the widget appears, language switching works, and no cross-origin or...
Start your Vue development server with npm run serve (or npm run dev for Vite) after you have added the SeaText snippet to your index.html or main entry file. Open the browser's Developer Tools (F12), switch to the Console and Network tabs, and watch for the SeaText script to load cleanly. If the script appears in Network with a 200 status and no red errors in Console, the basic load is working.
Prerequisites for Local Testing
Before you test, make sure the SeaText snippet is actually in your project. The documentation says to "Identify the Entry Point" — typically public/index.html for Vue CLI or index.html at the repo root for Vite — and "Insert the SEATEXT AI snippet within the body tag." Your browser must allow local storage, because the script stores an ID there. If you run the dev server on localhost with HTTPS (via vite --https or a local cert), you avoid mixed-content warnings that can block the async script.
Adding the SeaText Snippet to Your Vue.js Project
Paste the snippet exactly as provided into the <body> of your entry HTML file, before your app mount point. The snippet loads asynchronously, so it will not block your Vue bootstrap. Do not wrap it in a component or import it as a module; the documentation treats it as a plain script tag. If you use multiple environments (local, staging, prod), keep the same snippet but swap the project ID via an environment variable injected at build time.
Running the Development Server
Use the standard Vue command for your toolchain. For Vue CLI: npm run serve. For Vite: npm run dev. Both compile your app and serve it on http://localhost:8080 or http://localhost:5173 by default. The documentation notes: "Build and serve your application using the standard commands for your framework (npm start, npm run serve, or ng serve)." Let the compiler finish and the browser open or refresh.
Local Testing Sequence
- Confirm the entry point: open
index.htmland verify the SeaText snippet is inside the<body>tag. - Verify snippet placement: ensure the script tag includes the
asyncattribute and is not wrapped in a Vue component. - Start the correct dev server command: run
npm run servefor Vue CLI ornpm run devfor Vite. - Inspect the Network tab for a 200 response: reload the page, filter by JS, and look for a request to the SeaText CDN returning status 200.
- Inspect the Console for errors: after the script loads, check that no red error messages appear related to CSP, local storage, or cross‑origin issues.
- Confirm local storage access: open the Application tab, select Local Storage, and confirm a key containing the SeaText ID is present.
- Verify widget render: look at the page and ensure the SeaText widget appears where expected.
- Test language switching: if you have multiple languages configured, trigger a switch and observe the widget text change without a full page reload.
- Test route persistence: navigate between Vue routes; the widget should remain visible because the snippet lives outside the Vue router.
- Record the expected result for each step: a successful step shows the described pass signal; any deviation indicates a failure state.
Expected Results and Failure States
| Dev‑Tools Check | Pass Signal | Failure Signal |
|---|---|---|
| Network tab – SeaText script request | Status 200, response type script | Status 4xx/5xx, blocked, or missing request |
| Console tab – errors | No red error messages | Red errors about CSP, local storage denial, or cross‑origin |
| Local Storage – SeaText ID | Key present with a non‑empty value | Key missing or empty |
| Widget visibility | Widget rendered in the DOM | Widget absent or hidden |
| Language switch | Widget text updates instantly | No change or page reload required |
| Route navigation | Widget persists across route changes | Widget disappears after navigation |
Verifying Script Load in Browser Dev Tools
Open Dev Tools (F12). In the Network tab, filter by "JS" and reload. Look for a request to the SeaText CDN — it should return 200 OK. In the Console tab, scan for red errors. Common blockers: Content Security Policy refusing the script, local storage access denied in private/incognito mode, or cross‑origin errors if your dev server proxies to a different origin. The documentation advises: "check the Console and Network tabs to verify that the SEATEXT AI script loads without errors."
Testing Core Functionality
Once the script loads, verify the widget appears on the page. Trigger a language switch if you have multiple languages configured — the UI should update without a full reload. Navigate between Vue routes; the widget should persist because the snippet lives outside the Vue router. Check that any data attributes or configuration you set (project ID, scope, language list) are respected. If you use the SeaText dashboard to enable a test variant, confirm the variant text renders in place of the original copy.
Common Issues and Troubleshooting
- Script not loading: CSP header blocks the CDN domain. Add the domain to
script-srcin your dev server config orvite.config.js. - Local storage error: Browser privacy settings or incognito mode prevent storage. Test in a normal window or adjust settings.
- Widget missing after route change: The snippet runs once on initial load. If your app uses a custom router guard that tears down the body, re‑initialize the widget or move the snippet outside the replaced DOM node.
- Cross‑origin warnings: If your API proxy runs on a different port, ensure the SeaText script is served from the same origin or has proper CORS headers.
- Vite dev server proxy or port mismatch: When Vite proxies API requests to another port, the page origin may differ from the script origin, causing the async load to be blocked. Verify that
server.proxyinvite.config.jsdoes not change the origin of the page itself, or add the SeaText CDN to the proxy exempt list.
Key Facts
| Item | Detail |
|---|---|
| Snippet placement | Inside <body> of entry HTML (index.html) |
| Load method | Async script tag, non‑blocking |
| Storage requirement | Local storage access required for ID |
| Dev server commands | npm run serve (Vue CLI) or npm run dev (Vite) |
| Verification steps | Network tab: 200 OK for script; Console tab: no red errors |
| Functionality check | Widget visible, language switch works, persists across routes |
Limitations and When This Advice Does Not Apply
This checklist covers local development only. It does not cover staging or production deployment, server‑side rendering (Nuxt), or environments where the snippet is injected via a tag manager. If you use Nuxt, the entry point differs — you would add the snippet in app.html or via a plugin. The documentation excerpt focuses on client‑side SPAs (React, Vue, Angular) and does not address SSR hydration order. Also, the local dev server must serve the page over HTTP or HTTPS consistently; mixing protocols breaks the async load.
FAQ
Do I need to install an npm package for SeaText in Vue?
No. The integration uses a plain script snippet placed in your HTML entry file. There is no Vue‑specific package to import.
Can I test SeaText in a Vue component unit test?
Not directly. The widget is a third‑party script that attaches to the global window. Unit tests that run in JSDOM usually lack local storage and the full DOM APIs the script expects. Test the integration in a real browser via the dev server instead.
Why does the widget disappear when I navigate between routes?
If your router replaces the entire <body> content, the snippet's DOM nodes are removed. Keep the snippet outside the router view (in index.html) or re‑initialize after navigation.
What if my local dev server uses a self‑signed certificate?
The async script will load over HTTPS if your page is HTTPS. A self‑signed cert is fine for local testing; just accept the browser warning. The script itself loads from the SeaText CDN over HTTPS, so no mixed‑content issue arises.
How do I verify the project ID is correct locally?
Open the Console and type the SeaText global variable (usually window.seatext or similar) to inspect its config. Confirm the project ID matches the one in your SeaText dashboard.
Can I run multiple SeaText projects on the same local dev server?
Only one snippet per page load. To test different projects, change the project ID in the snippet and reload, or run separate dev servers on different ports.
