Quick Answer: SeaText SPA Integration Options
The SeaText SPA documentation does not include configuration flags named autoDetectLanguage, translateOnRouteChange, or fallbackLocale. For context, autoDetectLanguage would pick a language on first load, translateOnRouteChange would retranslate after a route change, and fallbackLocale would be the fallback language, but none of these names appear in the supplied source pack. Check with the vendor before relying on them.
The documented choices that affect SPA integration are: where you place the snippet, async loading, localStorage permission, cross-origin behavior, and framework verification.
| Decision area | What to check | Recommended setup |
|---|---|---|
| Snippet placement | Where does the app mount? | Add the snippet to the body tag or the framework bootstrap file. |
| Loading mode | Does the script block first paint? | Keep the async attribute from the SeaText snippet. |
| Storage permission | Can the page use localStorage? | Allow localStorage so SeaText can store a visitor ID. |
| Cross-origin calls | Does the SPA use multiple domains? | Test the snippet on every domain and fix CORS issues. |
| Framework workflow | React, Vue, or Angular? | Run the framework's dev server and inspect via DevTools. |
Recommendation: If your SPA uses client-side routing and multiple domains, place the snippet in the bootstrap file, keep async loading, allow localStorage, and test after a route change. If you need a different behavior, contact SeaText for the current configuration guide.
Why the Integration Setup Matters
A single-page application changes content without a full browser reload. The SeaText snippet rewrites visible text based on the active page and route. If the snippet is not set up correctly, translations may not start, or they may appear late.
The official SeaText docs explain that SPA integration has a few core requirements. You need to identify the entry point, add the snippet in the right place, and verify that the app has the permissions the script needs.
This is not a set of optional extras. These decisions control whether the snippet runs at all.
How the Async Snippet Preserves Page Load
The SeaText snippet includes the async attribute for the script tag. According to the docs, this ensures that the SeaText AI script loads asynchronously. That helps maintain page load performance.
An async script downloads in the background. It does not force the browser to stop parsing the page. This matters in an SPA because the app code, routes, and API calls already use a lot of bandwidth.
If the snippet loaded synchronously, it could delay first paint. The async attribute avoids that problem.
Keep the async attribute as it is in the supplied snippet. Do not remove it during copy-paste or build steps.
Entry-Point Placement: The First Decision
The SeaText docs say you must identify where your SPA initializes. This is typically an index.html file or a main JavaScript/TypeScript file where your framework mounts the application.
In React, the entry point is usually an index.html file with a root div. In Vue and Angular, the app often starts from a main.js or main.ts file. The snippet should be added within the body tag of index.html, or in the equivalent initialization section of your SPA framework.
Placement matters because an SPA does not reload the full HTML page on navigation. If the snippet is not in the initial entry point, it may not run when the app starts. It should be added once, not on every route.
Framework Installation: React, Vue, and Angular
The SeaText implementation guide covers React, Vue, and Angular. The steps are the same for all three.
First, build and serve your application using the standard commands for your framework. The docs list npm start, npm run serve, and ng serve.
Second, open your browser's Developer Tools with F12. Check the Console and Network tabs. Verify that the SeaText AI script loads without errors.
Third, confirm that SeaText features work inside your SPA. If a route changes and new text appears, the snippet is active.
For React, the docs call out a specific flow. After adding the snippet, use npm start to serve the app. Then inspect the page with Developer Tools. For Vue and Angular, use the same verification flow with their serve commands.
Local Storage Permissions and Cross-Origin Behavior
The SeaText script stores an ID in local storage. The docs say you must ensure your application has the necessary permissions to access and use local storage.
If localStorage is blocked, the snippet cannot store a stable ID. This can happen in strict privacy modes or in certain embedded browser contexts. The script may still load, but features that depend on the stored ID will not work correctly.
Cross-origin behavior is another documented requirement. If your SPA interacts with multiple domains, ensure that the SeaText AI script is compatible and does not face cross-origin issues.
For example, an SPA may load from a marketing site but call an API from another domain. In that case, check that the script is allowed to run in both contexts. The Network tab in DevTools will show failed requests if CORS blocks the snippet.
Verifying the Integration with DevTools
Verification is a required step in the SeaText SPA guide. Do not skip it after adding the snippet.
- Start your SPA with the framework's serve command.
- Open the site in a browser.
- Press F12 to open Developer Tools.
- Open the Console tab and look for errors.
- Open the Network tab and filter for script requests.
- Confirm that the SeaText script returns a successful response.
- Navigate between routes and check that the UI still behaves correctly.
This process is documented for React, Vue, and Angular. It gives you a clear pass or fail signal before you deploy.
Limitations and Troubleshooting
The official docs list a few limitations. Use these as your first troubleshooting checklist.
If the script does not load, check the entry point. It may be missing from the body tag or the framework initialization file.
If localStorage is blocked, SeaText cannot store its ID. Change the browser or app permissions and test again.
If your SPA uses multiple domains, cross-origin errors may stop the script. Review the Network tab and fix CORS-related failures.
If the snippet was added but the built version does not include it, inspect the production bundle. Some build tools purge unused code or move assets.
The SeaText docs cover React, Vue, and Angular. Other frameworks are not described in the source pack. Check with the vendor if you use a different framework.
Frequently Asked Questions
- Are autoDetectLanguage, translateOnRouteChange, and fallbackLocale official SeaText options?
- They do not appear in the supplied SeaText documentation. Check with the vendor for the current configuration guide.
- Does SeaText hurt page speed in a SPA?
- The docs say the snippet includes the async attribute. This helps maintain page load performance.
- Why does SeaText need localStorage?
- It stores an ID in local storage. Your application must allow localStorage access.
- Where should I add the SeaText snippet?
- Add it within the body tag of index.html, or in the equivalent initialization section of your SPA framework.
- Can I use SeaText with Vue or Angular?
- Yes. The docs list React, Vue, and Angular. Use the same serve command and DevTools verification steps.
- How do I verify SeaText in my SPA?
- Run the framework's serve command, open DevTools, and check the Console and Network tabs for errors.
