Its been a minute working Nestjs... Flexibility is key in modern API development. That's why I've embraced a hybrid approach in my backend using NestJS, and it's a game-changer. My single NestJS application serves both a traditional REST API and a powerful GraphQL API, giving us the best of both worlds. For standard CRUD operations? REST endpoints are fast, simple, and reliable. For complex data fetching on the client-side? GraphQL lets our frontend ask for exactly what it needs, reducing over-fetching and improving performance. And how do we secure it all? With a unified token-based authentication system. JWTs (JSON Web Tokens) protect every request, whether it's to a REST controller or a GraphQL resolver, ensuring consistent security across the board. Kudos to the NestJS framework for making sophisticated architectures like this not only possible but also maintainable and scalable. Familarity with Java notations is a banger when developing APIs with Nestjs. It gives a whole different understanding of class and object relations in Javascript. #APIdevelopment #Backend #NestJS #TypeScript #GraphQL #RESTfulAPI #JWT #Authentication #WebDev

Day 34 🚀 | Mastering HTTP Requests with JavaScript Real progress in frontend starts when your apps stop being static and begin talking to real servers. That’s exactly what I focused on today. Spent time getting hands-on with the fetch() API......understanding not just how it works, but how to use it cleanly and effectively in real-world scenarios. Here’s what I worked through 👇 • Built requests using fetch() with proper configurations • Deep-dived into request options (method, headers, body) • Practiced core HTTP methods: GET → Fetching data from APIs POST → Sending structured data PUT → Updating existing resources DELETE → Removing data cleanly • Learned how to handle responses properly using: response.status for debugging response.json() for structured data response.text() when needed What stood out today: ✔ Writing cleaner, more predictable API calls ✔ Understanding how frontend actually communicates with backend ✔ Feeling more confident integrating real APIs into projects This is the layer where applications start to feel alive. And honestly, getting comfortable here makes everything else easier. Consistency is starting to compound now. On to the next one. 💪 #WebDevelopment #JavaScript #Frontend #APIs #100DaysOfCode #Consistency #BuildInPublic #Developers

IT TOOK ME 2 MONTHS I built a tool that eliminates one of the most repetitive parts of backend development. Introducing: Visual API Orchestrator It lets you: • Design your database visually • Generate Prisma schema instantly • Create full CRUD APIs automatically • Export a complete backend project (ready to run) No more writing boilerplate for every project. What used to take hours now takes minutes. Tech stack: React + TypeScript Node.js + Express Prisma + SQLite This is a production-grade MVP focused on developer productivity. I’d love your feedback. #buildinpublic #webdevelopment #javascript #react #nodejs #prisma

🚀 Ever wondered what actually happens when you run a Node.js application? Most developers use Node.js daily for APIs and backend services, but the real magic happens behind the scenes. Let’s break it down using the architecture shown in this diagram 👇 🔹 1️⃣ Application Layer This is where we write our JavaScript code — building APIs, handling routes, and defining business logic. 🔹 2️⃣ V8 JavaScript Engine Node.js uses Google’s V8 Engine to convert JavaScript code into machine code so the system can execute it quickly. 🔹 3️⃣ Node.js Bindings (Node APIs) These bindings act like a bridge between JavaScript and the operating system, allowing Node.js to perform tasks like file handling, networking, and process management. 🔹 4️⃣ Libuv – The Asynchronous Engine Libuv is the core library that powers Node.js asynchronous behavior. It manages the event loop and enables non-blocking I/O operations. 🔹 5️⃣ Event Queue & Event Loop When tasks like file reading, API calls, or database queries are triggered, they are placed in the event queue. The event loop continuously checks the queue and executes callbacks when the main thread becomes free. 🔹 6️⃣ Worker Threads If a blocking operation occurs (like file system operations or heavy tasks), libuv sends it to worker threads in the thread pool. Once the work is done, the callback returns to the event loop and the response is sent back to the application. 💡 Why is Node.js so powerful? Because it follows an event-driven, non-blocking architecture, allowing it to handle thousands of concurrent requests with a single thread. That’s why Node.js is widely used for: • REST APIs • Real-time applications (chat apps) • Streaming services • Microservices architectures 📌 Learning Node.js becomes much easier when you understand how the Event Loop + Libuv + V8 Engine work together. #NodeJS #BackendDevelopment #JavaScript #WebDevelopment #SoftwareEngineering #LearningInPublic

Did migrating to Bun break our backend? Nope. But it sure made me rethink every assumption I'd had about Node.js. Last month, I switched our API server from Node to Bun. Same code, same endpoints - just a different runtime. Here’s what actually changed: Cold starts went from 1.2s to 400ms. That one actually matters - it's what made serverless worth revisiting for us. Nothing else changed, just that. npm install went from 45s to 8s. Our CI pipeline got 5 minutes faster. Developers aren’t context-switching during installs anymore. Memory usage? Stayed the same. The whole "Bun uses less RAM" hype didn’t hit us. We’re still at ~180MB under load. The real win? Native TypeScript execution. No build step for local dev. No ts-node overhead. Just run the file - easy peasy. Would I migrate a production monolith tomorrow? Not yet. The ecosystem's still young. But for new services? Absolutely. The future of JavaScript runtimes isn’t just about replacing Node. It’s about having options. What’s stopping you from trying Bun on your next side project? ♻️ Repost if you're curious about modern JavaScript runtimes! #Bun #NodeJS #WebDevelopment #JavaScript #PerformanceOptimization

It’s a carefully designed system where several components work together to handle massive concurrency.

Full-stack TypeScript with tRPC is one of those stacks that just clicks. You define your backend procedures once, infer types on the client automatically, and remove a huge class of API bugs without generating clients or maintaining duplicate schemas. Why it’s powerful: - End-to-end type safety from server to frontend - Autocomplete everywhere - Safer refactors - Faster development with less glue code - Great fit for modern TypeScript apps What I like most about tRPC is that it keeps the developer experience simple: - No handwritten API contracts - No codegen step - No guessing what the backend returns - Just TypeScript, shared across the stack It’s especially compelling for teams building quickly with: - React / Next.js - Node.js backends - Zod for validation - Prisma or other typed data layers Type safety won’t replace good architecture, but it does remove friction and boosts confidence when shipping. If you’re already all-in on TypeScript, tRPC is worth a serious look. #TypeScript #tRPC #FullStack #WebDevelopment #DX #Nextjs #React #Nodejs #SoftwareEngineering #WebDevelopment #TypeScript #Frontend #JavaScript
