Initially, create a blank service-worker.js file inside the public folder. Add the following code to it:

Step 3- Tell the browser it’s a web application-

Then, you need to add some code to inform the browser that this, not an ordinary web application; this is the web application. So add the following code inside <head> tag in the index.html file.

  • <link rel=”stylesheet” href=”” integrity=”sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm” crossorigin=”anonymous”>

Next, create a new project based in the firebase-console with the name React web application app. Run the following commands in a project directory:

  • npm install –g firebase –tools
  • firebase login
  • firebase init

After the initialization of the firebase, your firebase.json file should look like this.
