What is public/manifest.json file in create-react-app?

Viewed 94071

I know that chrome extensions use 'manifest.json`, but here, it is used as something else as well.

contents -

{
  "short_name": "React App",
  "name": "Create React App Sample",
  "icons": [
    {
      "src": "favicon.ico",
      "sizes": "192x192",
      "type": "image/png"
    }
  ],
  "start_url": "./index.html",
  "display": "standalone",
  "theme_color": "#000000",
  "background_color": "#ffffff"
}

When I change some value, page update, but nothing changes.

manifest.json is the json file that is mostly used to describe our app On mobile phones

The manifest.json provides information about a web application in a JSON text file, necessary for the web app to be downloaded and be presented to the user similarly to a native app (e.g., be installed on the homescreen of a device, providing users with quicker access and a richer experience). PWA manifests include its name, author, icon(s), version, description, and list of all the necessary resources (among other things).
