If you are starting with a new React project, the easiest way to get started is with the React Starter Kit. You can create a React project using the following command and then install firebase and firebase-tools. If it is an existing React and Firebase project, you can skip the installation steps:

npm install -g create-react-app

You can install Firebase using the following command:

npm install firebase --save

You will also need to install the Firebase CLI to run your project on a server. It can be installed using the following command:

npm install -g firebase-tools

Now, we will extend the Helpdesk application with FCM implementation.
