![]() Our app should start on localhost:3000 of our default browser with spinning react icon and a link to learn react. ![]() See more about creating react-app Now let's start our created app, to do that we run npm start in the terminal. with the dot to create the app inside our firebase-todos folder. Now let's run our command npx create-react-app. Now from your code editor open the folder firebase-todos then click on terminal in the vs-code navigations and click on new terminal, before we start running the Npm CLI-commands we first have to check whether Node.js is properly installed by running node -version which will show us the version of node successfully installed. Next thing is creating an empty folder in any directory on your computer preferably Desktop, with a folder name of your choice, in my case firebase-todos You should be fairly familiar with React.js and JavaScript.You should have a code editor installed on your computer, I suggest VS-Code.You should have Node.js installed on your computer.In this tutorial we will be learning how to store and retrieve data in firebase by building a todo-list app. We will use React (also known as React.js or ReactJS) a free and open-source front-end JavaScript library for building user interfaces or UI components. In October 2017, Firebase has launched Cloud Firestore, a real-time document database as the successor product to the original Firebase Realtime Database The product assists software developers in building real-time, collaborative applications. Its first product was the Firebase Realtime Database, an API that synchronizes application data across iOS, Android, and Web devices, and stores it on Firebase's cloud. It was originally an independent company founded in 2011. We will use Firebase a platform developed by Google for creating mobile and web applications. Developers who don’t use cloud will have less secure software and computer networks that can result in loss of key data. Cloud systems enable you to maintain data integrity and data recovery. The use of cloud will also help companies and developers make systems more secure. These remote servers are used to store, manage and process data. Finally, add in any CSS styles, spin up the development server to save the changes, and head over to your browser to view the final results.Cloud computing is the use of a network of remote servers that are hosted on the internet. It checks if a user is authenticated, and renders the Chat component otherwise the SignIn component is rendered. ![]() The authentication status is destructured from the Firebase authentication component with the help of the useAuthState hook from the react-firebase-hooks package. This code renders the SignIn and Chat components conditionally by checking the authentication status of a user. Copy the environment variables from your firebase project dashboard and paste them into this file. In your src directory, create a new file and name it, firebase-config.js. npm install firebase react-firebase-hooks Configure Firebase in Your React Application Additionally, import the react-firebase-hooks package that simplifies working with Firebase In React. Next, create a React application and install the Firebase SDK in your application. ![]() Take note of the instructions for integrating Firebase's SDK to your project under Add Firebase SDK.
