I created a cloud database using MongoDB Atlas. So, if you want to run our code then please read the instructions below :

• Clone our repository https://github.com/srinivasGokarla/Evallo
• Open the code in your VS code, and open the Backend folder in the terminal by running cd Backend -Now run npm install or npm i which will install all the required packages of node
• After installation, now run npm run server and you will see the server is listening on 5000
• Simultaneously, open a new terminal and run cd frontend by which you get into the frontend folder
• Now here, run npm install or npm i which will install all the required packages of react as well
• After installation, now run npm start and you will see a new window opening in the default browser which is running on port http://localhost:3000
• Open MongoDb compass and URL mongodb://localhost:27017/users which will create a database collection named users
• Now you see the app running, you can click on Register to sign in and after that, you will be redirected to the Home page.
