Git Rebase Explained A rebase takes your commits and moves them on top of another branch, creating a cleaner history. Imagine:

main:
A---B---C

feature:
     D---E

After rebasing:

main:
A---B---C---D---E

Your feature looks like it was created from the latest version of main. Teams use it: - To maintain cleaner commit history. - For easier code reviews. - Fewer unnecessary merge commits. 📌 The rule: Rebase your local work. You have to be careful rebasing commits that other people already use.

React Context (How to stop your React components from rendering unnecessarily)

Your useEffect Might be Doing Too Much

An effect is code that runs after React updates the screen, usually for interacting with things outside React.

Examples: Fetching data, Subscribing to events, Updating the document title. The problem starts when developers use it for normal calculations. Example:

useEffect(() => {
  setTotal(price * quantity)
}, [price, quantity])

This creates unnecessary work. total can already be calculated during rendering. The effect adds another state update, another render, and another thing to debug. A useful question:

Does this code synchronize with something outside React?

If not, it probably doesn't belong inside useEffect.

📌 React Isn't the Problem A React app doesn't become slow overnight. It becomes slow when unnecessary render accumulates overtime.

A render is React running a component again to determine what should appear on the screen.

Most developers reach for useMemo, useCallback, or another optimization as soon as performance drops. That's often treating the symptom. The better question is: Why did this component render in the first place? Open React DevTools and enable Highlight updates. Click around your app. If your navigation bar flashes every time you type into a search box, you've already found a performance issue.

What is Next.js Middleware❔

Why React Hydration Exists When a server sends HTML to your browser, the page already looks complete before any JavaScript finishes loading. But looks can be misleading. Buttons don't respond. Forms don't submit. Dropdowns don't open.

Hydration is the process where React attaches JavaScript to that existing HTML, making it interactive instead of rebuilding the page from scratch.

This is also why JavaScript bundle size matters so much. The browser can't hydrate components until it has downloaded, parsed, and executed their JavaScript. That's why modern frameworks push more work to the server. Not because JavaScript is bad, but because sending less of it usually means users can interact with the page sooner.

❌ Stop Returning 200 One habit that makes debugging APIs much harder is returning HTTP 200 OK for every request. An HTTP status code tells the client what happened before it even reads the response body. Examples: 200 → Success 201 → Resource created 400 → Client sent invalid data 401 → Authentication required 403 → Authenticated, but not allowed 404 → Resource doesn't exist 500 → Server failed unexpectedly If every response is 200, frontend developers have to inspect every response body just to know whether something failed. Let HTTP do its job. That's what it was designed for.

📖 Read The Source When you're stuck with a library, stop searching YouTube after 20 minutes. Open its documentation. If that doesn't explain it, read the source code. You don't need to understand every file. Find the function you're calling and follow the execution. You'll often discover hidden options, edge cases, or implementation details that never made it into the docs. Reading source code is one of the fastest ways to become a stronger developer.

The Truth About CORS

CORS (Cross-Origin Resource Sharing) is a browser security mechanism that decides whether one website is allowed to request resources from another.

Suppose your frontend runs on:

http://localhost:5173

Your API runs on:

http://localhost:3000

Same computer. Different ports. That makes them different origins. Your browser blocks the request because the API never explicitly allowed requests from that origin. "But it works in Postman..." Of course it does. Postman isn't a browser. It doesn't enforce browser security rules.

If Postman works but your browser doesn't, the problem usually isn't your API logic. It's your server's CORS configuration.

🚨Someone open-sourced the Kage landing page and the Three.js skills behind it. Every section scrolls through a 3D world and the whole thing is under 1MB of Three.js and code, 3MB with high quality images. For a fully 3D scroll experience that's surprisingly lean. Three skills included: build-threejs-scroll-worlds, falling-leaves and pointer-trail-emitter. All open source on GitHub. 🔗Check it out: https://github.com/MengTo/kage
