React-Manifest is a simple library that allows you to easily update your manifest.json file in your React application. It allows you to specify the details of your application such as the name, icons, and related applications.
Installation
with npm
npm install react-manifest
with yarn
yarn add react-manifest
Step 2
Import the package in your React component
import reactManifest from "react-manifest"or
const reactManifest = require("react-manifest")Step 3
Add a <link> tag in your index.html file with the id attribute set to "manifest-placeholder" and href attribute set to "./manifest.json"
<link rel="manifest" id="manifest-placeholder" href="./manifest.json" />Step 4
In your React component, create an object with the details you want to update in your manifest.json file. For example:
const manifestDetails = {
"name": "My Web App",
"short_name": "My App",
"start_url": "index.html",
"display": "standalone",
"orientation": "portrait",
"theme_color": "#000000",
"background_color": "#ffffff",
"icons": [
{
"src": "icon-192x192.png",
"sizes": "192x192"
},
{
"src": "icon-512x512.png",
"sizes": "512x512"
}
],
// And More...
}
Step 5
Use the update method to update your manifest.json file by passing in the manifest details and the id of the <link> tag in your index.html file.
