JavaScript not working after publishing a static page
JavaScript often fails after publishing because script paths are wrong, module files are missing, browser security rules changed, or the page expects a local development server.
Quick answer
Check script src paths, include every JS file in the ZIP, avoid local-only APIs, and verify whether the page needs a build step before upload.
Real use cases
A page generated by an AI tool references a missing script file.
A Vite or React project was uploaded before being built into static files.
Steps
1
Open the browser console
Look for 404 errors, module errors, CORS messages, or syntax errors.
2
Verify script paths
Confirm every script src in the HTML exists in the uploaded file or ZIP.
3
Upload static output
For framework projects, build first and upload the static output, not the raw source project.
Examples
Missing main.js
The HTML references js/main.js, but the ZIP only contains index.html. Add the js folder and republish.
Unbuilt app
A Vite source folder needs npm run build first. Uploading src files alone will not create a working static preview.
Practical tips
- Use relative script paths.
- Keep JS files in the ZIP.
- Check module type and build output.
- Test in a clean browser session.
Common mistakes
- Uploading source files instead of built static files.
- Referencing localhost APIs.
- Forgetting a bundled JS file.
- Ignoring console errors.
Best practices
- Use a production build for framework output.
- Keep static dependencies together.
- Use browser dev tools before asking reviewers to test.
- Document unsupported server-side behavior.
FAQ
Can HTMLShare run server-side JavaScript?
No. HTMLShare is for static HTML, CSS, JavaScript, images, and ZIP projects. Server code needs a different hosting platform.
Why does JavaScript work locally but fail online?
Local files may rely on paths, dev servers, or files that were not included in the uploaded static output.
Should I upload my Vite source folder?
Usually no. Build the project first, then upload the static output folder or ZIP.
Turn the HTML into a link
HTMLShare can publish static JavaScript projects, but the uploaded files must be complete static output with valid relative paths.
