什么是create-react-app中的public/manifest.json文件? [英] What is public/manifest.json file in create-react-app?

问题描述

我知道chrome扩展使用'manifest.json`，但是在这里，它也被用作其他东西.

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

内容-

{
  "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"
}

当我更改某些值时，页面会更新，但没有任何变化.

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

推荐答案

这是描述您的应用程序的Web App Manifest ，例如，移动电话(如果在主屏幕上添加了快捷方式).

It's a Web App Manifest that describes your application and it's used by e.g. mobile phones if a shortcut is added to the homescreen.

从MDN(上面链接):

From MDN (linked above):

Web应用程序清单在JSON文本文件中提供有关应用程序的信息(例如名称，作者，图标和描述).清单的目的是将Web应用程序安装到设备的主屏幕上，从而为用户提供更快的访问权限和更丰富的体验.

The web app manifest provides information about an application (such as name, author, icon, and description) in a JSON text file. The purpose of the manifest is to install web applications to the homescreen of a device, providing users with quicker access and a richer experience.
