SchoolOS Backend: Node.js MIS API with MongoDB

🎥 MERN Stack Learning Journey – Backend Demo Here’s a demo of my Student Result Management API built using Node.js & Express. In this video: 🔹 Adding student data using POST API 🔹 Sending JSON data via Postman 🔹 Fetching student result using ID (GET API) 🔹 Automatic result calculation (Total, Average, Grade) 💻 Currently learning MERN Stack and exploring backend development step by step. This project helped me understand how APIs work in real-world applications 🚀 Next step 👉 Connecting MongoDB for database storage #MERNStack #NodeJS #ExpressJS #BackendDevelopment #RESTAPI #LearningJourney #WebDevelopment

🚀 Today I revised how the backend actually works (end-to-end flow) Instead of just coding blindly, I focused on understanding the complete request lifecycle: 👉 Client → Routes → Middleware → Controller → Model → Database → Response 💡 Key Learnings: - Middleware handles authentication, validation & errors before logic - Controllers should be clean and focused on business logic - Models interact with the database, not directly from routes - Proper flow = clean, scalable backend architecture This revision helped me connect all the pieces of MERN backend in a structured way. Now things feel much more clear and practical 🔥 Consistency > Motivation. Small revisions like this build strong fundamentals.

I’m pleased to share my latest project — Script XP, a Gamified DSA Learning Platform. Script XP is designed to make learning Data Structures and Algorithms more engaging by combining structured problem-solving with a gamified user experience. The platform focuses on improving consistency, motivation, and overall learning efficiency for students and developers. Key Highlights: • Gamified approach to DSA practice • Intuitive and responsive user interface • Structured learning flow for better retention • Seamless frontend-backend integration Tech Stack: MongoDB | Express.js | React.js | Node.js | Axios Live Application: https://lnkd.in/g9hhaeiZ Through this project, I strengthened my full-stack development skills and gained hands-on experience in building scalable and interactive web applications using the MERN stack. I welcome any feedback or suggestions. #FullStackDevelopment #MERNStack #ReactJS #NodeJS #MongoDB #DSA #WebDevelopment #SoftwareDevelopment

I’ve been spending some time lately diving into NestJS to get a better grasp on backend architecture. To practice, I wanted to build something a bit more hands-on than a standard to-do list app. I ended up putting together a simple API Health Monitor. It's a background service that takes a list of URLs and automatically pings them at set intervals to log their latency and status codes. A few key things I learned while building this: ⏱️ Background Scheduling: Got to explore @nestjs/schedule to run automated CRON tasks without blocking the main app. 🗄️ TypeORM Relations: Handled the database side by linking monitoring targets to their ongoing history logs. 🛡️ Data Validation: Set up DTOs with class-validator to make sure the API catches bad data (like broken URLs) right at the door. 🚦 Exception Filters: Wrote a global interceptor so the API always returns a consistent error format. It was a really helpful way to see how background processing and defensive programming work together in a framework like Nest. Still have a lot to learn, but it’s pretty satisfying to watch a server do its own thing in the background! If any backend devs have favorite resources or best practices for NestJS, I’m all ears. 👇 GitHub Repo : https://lnkd.in/gjajerCQ #NestJS #TypeScript #BackendDevelopment #LearningToCode #TypeORM

1. What we built • Full-stack blogging platform (MEDIUM-style but mine) • Monorepo setup → backend + frontend + shared • Backend foundation using: • Node.js + Express + TypeScript • MongoDB Atlas + Mongoose • Clean architecture • First successful run: • MongoDB connected • Server live on localhost 2. What problems I faced • Folder structure confusion (what goes where?) • TypeScript setup felt overwhelming initially • Understanding proper project architecture before coding • That “blank folder anxiety” hits hard 3. How I fixed it • Took a step back → designed structure before coding • Broke things into small chunks (DB → server → validation) • Focused on fundamentals instead of rushing features • Debugged patiently instead of copy-pasting from tutorials • Trusted the process (even when nothing worked initially) All thanks to the Sheryians Coding School Harsh Vandana Sharma Ankur Prajapati #FullStack #DSA #BuildInPublic #LearningInPublic

🚀 Excited to share my latest full-stack project — Open Feedback Honest feedback is often easier to give when it can be shared anonymously. With that idea in mind, I built Open Feedback — a platform where users can create an account, generate a unique public URL, and share it anywhere. Anyone with the link can submit anonymous feedback without logging in, and all responses are displayed in the user’s dashboard, where feedback can be enabled or disabled at any time. ---Technical Highlights: * Optimized dashboard message retrieval using MongoDB Aggregation Pipeline * Implemented schema validation with Zod for robust API and data handling * Added secure authentication using Auth.js * Built OTP/email verification workflows with Resend * Designed scalable database schemas with MongoDB and Mongoose * Developed real-time username validation with debouncing and server-side uniqueness checks * Built the application with TypeScript for improved type safety and maintainability 🔗 Live App: https://lnkd.in/gypPZaq8 💻 Source Code: https://lnkd.in/gs5Bj8X5 📩 Send Me Anonymous Feedback Here: https://lnkd.in/gieS3jay Would love to hear your thoughts—and feel free to try it out by sending anonymous feedback through the link above! #NextJS #FullStackDevelopment #BackendDevelopment #TypeScript #MongoDB #WebDevelopment #SoftwareEngineering #Programming #ReactJS #JavaScript #BuildInPublic
