I built a website using the MERN stack (MongoDB, Express.js, React.js, and Node.js) and integrated a chatbot and a Facebook-like community feature. To connect the frontend and backend of the website, I used Axios, a library that allows me to make HTTP requests from the frontend, and Express.js, a framework for building web applications on top of Node.js. I also implemented login security and used MongoDB as the database for the website. MongoDB is a NoSQL database that allows for the storage of unstructured data and is often used in modern web development. By using the MERN stack, I was able to build a full-stack web application with a responsive and dynamic frontend, an efficient and scalable backend, and a flexible and powerful database. The chatbot and Facebook-like community feature I integrated add an interactive and social aspect to my website, providing users with an enhanced experience.
