"BMI Buddy is a Node.js web app enabling users to calculate their BMI swiftly. With intuitive design, it offers real-time updates and classification of BMI categories. Utilizing AJAX, it ensures seamless interaction, enhancing user experience and promoting health awareness."
Technologies Used:
Node.js: Backend JavaScript runtime environment. Express.js: Web application framework for Node.js. HTML/CSS: Frontend markup and styling. JavaScript: Client-side scripting for dynamic behavior. AJAX (Asynchronous JavaScript and XML): Used for asynchronous data exchange between the client and server. BMI Classification Algorithm: Logic to categorize BMI into different weight categories. Project Implementation:
Backend Development: Set up the Node.js environment and create routes to handle HTTP requests for BMI calculation. Frontend Development: Design a user-friendly interface using HTML/CSS and implement dynamic behavior using JavaScript. BMI Calculation: Implement the BMI calculation logic based on the provided height and weight inputs. Classification: Classify the calculated BMI into appropriate weight categories (underweight, normal weight, overweight, obese). AJAX Integration: Utilize AJAX for seamless communication between the client-side interface and the server for real-time updates. By developing this BMI Calculator web application, users can conveniently assess their body mass index and gain insights into their overall health status. This project serves as an educational tool and demonstrates the practical application of Node.js in web development.
