Why I Built a Browser-Based Scientific Calculator Instead of Using an App
There are countless scientific calculator apps available today, but I kept running into the same problem. Most of them required installation, displayed too many ads, or felt unnecessarily complicated for everyday use.I wanted something differentβa calculator that opens instantly in a browser, works on any device, and provides all the essential scientific functions without getting in the way.That idea led me to build the Monkza Scientific Calculator.It includes the features that students, develop
The Everyday Backend Engineer: Step 6 β The Facade Pattern
Welcome back to The Everyday Backend Engineer: Practical Design Patterns. In our last installment, we learned how to dynamically stack features onto an object using the Decorator Pattern. Today, we remain in Category 2: Structural Patterns to explore an absolute lifesaver for controller cleanup: The Facade Pattern.Let's dive into how you can hide chaotic, multi-step backend orchestration behind a single, beautifully elegant function. π΄ The Problem: Controller Orchestration BloatImagine you
The Next.js Black Box: What Actually Happens Between Your React Code and the Browser
Most developers think Next.js simply converts React components into HTML strings and sends them to the browser.Then you open the "View Source" of your production App Router application, expecting clean HTML. Instead, you are greeted by thousands of lines of cryptic, unreadable JavaScript looking like this: self.__next_f.push([1, "M1:{\"id\":\"...\"}"]).If you have ever wondered what this payload is, why it exists, and how Next.js actually compiles your codebase, you are in the right place.Letβs

I created a platform with a list to help you share your projects π₯
Hello everyone! Today I'd like to share my new commercial open source project.One day, I had the idea to create a platform for projects. But I noticed that in most similar services, you just add your project, and the platforms don't care at all. I'd like to do it differently. It's called List a project and promote it!.But first, I'd like to say that the name was invented in ten minutes. It may be long, but I think it's perfectly fitting.Well, let me tell you in more detail. π What is this p
Editing React components that never rendered
~7 min read Β· EngineeringThere are only two ways a tool can learn the shape of your React code. Which one you pick decides the single most important thing about the tool: whether it's available in the exact moment you need it most. Two ways to know a codebaseRuntime introspection watches a running app. React DevTools, profilers, error overlays β they read the live fiber tree after the app mounts. This is the richer of the two: they know real prop values, real state, what actually rendered.
Type Safety Stops at Runtime Boundaries in React Native
TypeScript can make a React Native codebase safer.It can catch missing properties, incorrect function arguments, invalid component props and many other mistakes before the application runs.But TypeScript has one important limitation:It cannot verify whether external data actually matches the type you assigned to it.This becomes especially important in React Native because application data often crosses multiple runtime boundaries.A value may come from:a native Android modulean iOS native modulea
CORS + Auth Worked Perfectly Locally, Then Broke the Moment I Deployed (Here's Why)
I ran into this bug recently and it took me longer to fix than I'd like to admit: my React + Express app worked flawlessly on localhost, but the moment I deployed it, authenticated requests started silently failing. No errors in my own code β just requests that looked like they went out, but the backend never seemed to receive the session/token.The setupReact frontend and Express backend deployed to separate origins (different domains/subdomains)Auth relying on a cookie (or JWT sent with credent
