Async/Await Simplifies React API Calling with Cleaner Code

🚨 𝐄𝐒𝟔 𝐌𝐨𝐝𝐮𝐥𝐞𝐬 𝐯𝐬 𝐂𝐨𝐦𝐦𝐨𝐧𝐉𝐒 𝐜𝐨𝐧𝐟𝐮𝐬𝐢𝐨𝐧 𝐏𝐫𝐨𝐛𝐥𝐞𝐦𝐬 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫𝐬 𝐅𝐚𝐜𝐞 👀 If you're working with Node.js, you've probably run into this confusion: Why does this work sometimes… import express from "express" …but other times only this works? 😑 const express = require("express") here is what dealing with ES Modules vs CommonJS looks like👇 1. "Cannot use import statement outside a module" Why it happens Node.js defaults to CommonJS, so "import" won't work unless you tell Node to use ES Modules. So how do you fix this? You simply add this to your "package.json": 👇 "type": "module" 2. "require is not defined" This happens when you're using: "type": "module" Now Node expects ES Modules, so "require()" won't work. How do we solve this? You use: import express from "express" 3. Mixing CommonJS and ES Modules This is one of the biggest headaches: const something = require("./file.js") But the file exports using: export default something Boom 💥🤯 errors everywhere. 4. File Extension Problems (.js vs .mjs) ES Modules often require: import file from "./file.js" Even when you're already inside ".js" Many developers forget this and get errors. 5. Default vs Named Export Confusion export default function (default export) Is different from: export const function (named exports) And importing them incorrectly causes: ❌ undefined errors ❌ runtime crashes ❌ silent bugs So when do you use Each? Use CommonJS When: - Working with older Node.js projects - Using older libraries - Working with legacy codebases Use ES Modules When: - Building modern apps - Using React / Vite / Next.js - Writing new backend projects This helps you to: ✅ Debug faster ✅ Work with legacy code ✅ Build modern backend apps ✅ Avoid production bugs Some developers don't struggle with backend logic… They struggle with module confusion. Once you master this, Node.js becomes much easier.

It allows you to run JavaScript outside the browser. Think of it as the powerhouse that handles your server-side logic. 🧰 𝗘𝘅𝗽𝗿𝗲𝘀𝘀.𝗷𝘀 𝗶𝘀 𝘁𝗵𝗲 𝗧𝗼𝗼𝗹𝗸𝗶𝘁 It’s a minimal and flexible framework built on top of Node.js. It simplifies things like routing, middleware, and handling HTTP requests. 𝗪𝗵𝘆 𝘄𝗲 𝘂𝘀𝗲 𝘁𝗵𝗲𝗺 𝘁𝗼𝗴𝗲𝘁𝗵𝗲𝗿: While you can build a server using just Node.js (with the http module), it requires a lot of manual code. Express turns 50 lines of "pure" Node code into 5 lines of readable, maintainable logic. 𝗠𝘆 𝗧𝗮𝗸𝗲: In 2026, efficiency is everything. Unless you are building something extremely low-level, Express (or similar frameworks like Fastify) is the standard for getting high-performance APIs into production quickly.

Today I went deeper into something that most beginners ignore but every backend developer eventually has to master structured error handling in JavaScript. In small scripts, errors crashing the program might not matter much. But when you start building APIs with Node.js and Express, unhandled errors can break the entire server. One pattern I found very interesting is the (async error wrapper), which removes repetitive try{}catch{} blocks from every route. Instead of writing this everywhere: try { const user = await User.findById(id) } catch (err) { next(err) } We can create a reusable helper: const asyncHandler = (fn) => (req, res, next) => Promise.resolve(fn(req, res, next)).catch(next) Now routes become much cleaner: app.get("/user/:id", asyncHandler(async (req, res) => { const user = await User.findById(req.params.id) res.json(user) })) Small patterns like this make a huge difference in large backend systems. This is the roadmap I followed to learn error handling in JavaScript. I hope it will be useful for you. 1.Types of errors 2.try catch 3.throw 4.error object 5.async error handling 6.promise catch 7.Express middleware error handling 8.custom error classes 9.logging errors 10.global error handling Still exploring deeper patterns used in production Node.js applications. #NodeJS #JavaScript #BackendDevelopment #SoftwareEngineering #CodingJourney

🚀 React Developers: Revisiting Data Fetching & Async Patterns Data fetching is one of the most common tasks in React. Yet, the way we handle asynchronous operations—whether through Promises or Async/Await—can completely change the readability and maintainability of our code. 👉 Key Insights Promises often lead to chaining, which can feel less readable. Async/Await makes code look synchronous, improving clarity. Error handling becomes cleaner with try...catch. In React, async functions inside hooks like useEffect need careful handling to avoid pitfalls. 💡 My takeaway: mastering Promises first helps you truly understand JavaScript’s asynchronous nature. Once that foundation is strong, Async/Await becomes the natural next step for writing cleaner, production-ready code. Question for you: Which approach do you prefer in your React projects—Promises or Async/Await? #ReactJS #JavaScript #AsyncAwait #Promises #WebDevelopment #Frontend

HOW REACT FETCHES DATA — Step-by-Step When learning React, API calls can feel confusing at first. But the process is actually a simple flow. This post explains the complete flow: • Component renders • useEffect runs • API call is made • Loading state is shown • Data is received • State updates • UI re-renders with new data In React, the UI doesn’t update because we change the DOM. It updates because the state changes. Understanding this flow makes data fetching much easier to reason about. 📌 Save this for revision. #React #FrontendDeveloper #WebDevelopment #JavaScript #InterviewPrep #LearningInPublic #ReactJS #Consistency

async/await is not free. Most Node.js developers don't know what it costs. Most developers treat async/await like magic. It isn't. Every await pauses that function. The event loop moves on. But if you chain awaits without thinking, you're writing sequential code in an async system. Here's what I mean: // Looks clean. Runs slow. const user = await getUser(id) const orders = await getOrders(id) const payments = await getPayments(id) Three database calls. Running one after the other. Total time: 120ms + 95ms + 80ms = 295ms These three calls have zero dependency on each other. There is no reason to wait for getUser before calling getOrders. // Fix: run them in parallel const [user, orders, payments] = await Promise.all([ getUser(id), getOrders(id), getPayments(id) ]) Total time: ~120ms (slowest call wins, rest run simultaneously) Same result. 2.5x faster. One line different. 3 rules I use on every Node.js project: → If calls don't depend on each other, run them with Promise.all → If one failure should cancel all, use Promise.all (it rejects on first error) → If you want all results even when some fail, use Promise.allSettled I see the sequential pattern in almost every codebase I audit. It's the most common Node.js performance mistake that never gets caught in code review because it doesn't look wrong.

Express.js was released in 2010. Yet in 2026, many new Node.js projects still start with it. The problem? • No native TypeScript support • No built-in validation • No schema system • Benchmarks 3–4× slower than modern frameworks Meanwhile frameworks like Fastify, Hono, and Elysia were built for the modern Node ecosystem. That doesn't mean Express is dead. But for new projects, it probably shouldn't be the default anymore. I wrote a quick 5-minute breakdown explaining: • What's wrong with Express in 2026 • Modern alternatives • A simple migration example (Express → Hono) Read the full article here: https://lnkd.in/ditYtufV What are you using for new Node.js projects in 2026? #NodeJS #JavaScript #BackendDevelopment #WebDevelopment #SoftwareEngineering

I just published an npm CLI tool called starter-structure-cli It scaffolds 30+ production ready starter projects from simple stack tokens. Instead of spending hours setting up boilerplate, you can just run: npx starter-structure-cli my-app react vite ts tailwind express prisma mysql and get a fully structured fullstack project ready to start coding. It supports React, Next.js, Vue, Vite, Tailwind CSS, shadcn/ui, Express, NestJS, Prisma, Mongoose, Sequelize, MongoDB, MySQL, PostgreSQL, JWT, and NextAuth. These technologies are available in the framework, but you only pick the stack you actually need for your project. It also supports 6 project types: Single App, Frontend, Backend, Fullstack, Monorepo, and Turbo Monorepo. Some highlights: Composable template system with layered bases, overlays, and presets Natural language matching with alias normalization Interactive terminal UI and non interactive mode for CI/CD Dynamic placeholder replacement across files, folders, and content Prepublish validation for template integrity Built with pure Node.js, ES Modules, and @clack/prompts with zero build tools. Who is this for? Beginners who want a proper project structure from day one and want to learn by working with real code. Experienced developers who want to skip repetitive setup and start building faster. Team leads and freelancers who want a consistent starting point across projects. Published on npm, Inc. and open for feedback, contributions, and improvements GitHub: https://lnkd.in/gn6VveUw npm: https://lnkd.in/gZfmaHxG dev : https://lnkd.in/gm_Tb4KA If you are tired of setting up the same boilerplate again and again, give it a try.
