PWA Manifest FAQs

Answers regarding client-side Progressive Web Application descriptors.

What is a manifest.json file?

It is a standard JSON metadata file that informs mobile and desktop devices how to install your web app as a standalone application on the home screen.

Where should I save the manifest.json file?

Download the file and save it in the root directory of your website, then add the metadata tag `<link rel="manifest" href="/manifest.json">` to your HTML `<head>` tags.

Is client-side manifest generation secure?

Yes. All parameter mappings and configuration builds are computed locally in your web browser. No server storage or logs are recorded.
