In This Code -- i create a backend and Frontend web page for SignUp and Login.....
When you go to terminal in this file and run the code "npm run dev" ---> Actually i have used nodemon and in package.json ( Script{ "dev":"nodemon src/app.js" ) -- now when you simply run "npm run dev" this command in terminal then you will see a page in which you can login and if you don't have account in this you can signup...
