Express Server Default Route

❌ secure: true looks correct 🚨 But breaks cookies on localhost in Next.js The fix is simple 👇 Let Node.js decide based on environment: secure: process.env.NODE_ENV === "production" ✔ Works on localhost ✔ Secure in production Save this it’ll save your debugging time 👨💻🔥 #NextJS #NodeJS #WebDevelopment #JavaScript #FullStackDeveloper #Authentication #Cookies #CodingTips #BugFix #SoftwareEngineering #DevTips

Server Actions or API Routes — which one should you actually use? 🤔 Let’s clear the confusion once and for all. #NextJS #ReactJS #WebDevelopment #FrontendTips #JavaScript

This diagram shows how a client sends a request, how the Node.js server processes it, and how the response is sent back. Node.js allows JavaScript to run on the server and handle multiple requests efficiently using a non-blocking approach.

If you are a Node.js developer and want to understand the inner workings of async operations in Node, this playlist by Vishwas Gopinath can help. I found it really helpful and definitely worth checking out. #nodejs #javascript

Server Actions feel powerful — almost magical ✨ But many developers are using them unsafely. Let’s break down the common mistakes and the right way to use them. #NextJS #ReactJS #WebDevelopment #FrontendTips #JavaScript

👉 Event Loop in Node.js JavaScript is single threaded, but Node.js can handle many tasks at the same time. This is possible because of the Event Loop. 👉 What Event Loop does -Continuously checks if the call stack is empty -Picks the next task from queues -Executes it without blocking the main thread 👉 How it works -Synchronous code runs in the call stack -Async tasks like timers, file system, and APIs go to background Once the stack is empty, Event Loop pushes tasks back to execution 👉 Execution order -Microtask queue → Promises, process.nextTick -Timers queue → setTimeout, setInterval -I O queue → file system, network calls -Check queue → setImmediate 👉 Why it matters -Handles thousands of requests efficiently -Keeps the application fast and non blocking 👉 Key point Node.js is single threaded, but highly concurrent because of the Event Loop. #nodejs #javascript #eventloop #backenddevelopment #webDevelopment

Simple JavaScript challenge 🧑💻 What will be the output of this code? for ( var i = 0; i < 3; i++ ) {   setTimeout( () => {     console.log( i );   }, 0 ); } What's your answer? And why? #JavaScript #WebDevelopment #Frontend

Node.js – Day 9/30 The path Module When working with files in Node.js, hardcoding file paths can easily break across different operating systems. The path module helps handle file paths in a safe and consistent way. What the path module solves: o) Different path separators (/ vs \) o) Absolute vs relative paths o) Cleaner and more readable file handling Common usage: o) path.join() – safely joins paths o) path.resolve() – gets absolute paths o) __dirname with path for reliable file access Using the path module avoids environment-specific bugs and makes backend code more portable. #NodeJS #BackendDevelopment #JavaScript #FileHandling #LearningInPublic
