How to avoid circular dependencies in Redux with Dependency Injection

Async Redux confused me more than the code itself. Every diagram showed a simple loop. None explained where the API actually happens. This one finally made it click. 📌 The real async Redux flow in 7 steps: 1️⃣ View: User triggers an action (FETCH_USER_REQUEST) 2️⃣ Middleware: Thunk/Saga intercepts it 3️⃣ API Call: Side effect happens here 4️⃣ Action #2: Middleware dispatches FETCH_USER_SUCCESS with payload 5️⃣ Reducer: Pure function. Updates state only on success action 6️⃣ State: Central store gets fresh data 7️⃣ View Update: React re-renders UI 🔁 That’s the loop: View → Action → Middleware → API → Action → Reducer → State → View This diagram is one of the clearest visual explanations of async data flow in Redux that I’ve seen. If you’re learning Redux, save this. 👇 I’m curious: Which async approach do you use in React today? Saga? Thunk? RTK Query? Something else? #Reactjs #Redux #JavaScript #WebDevelopment #Frontend #StateManagement #ReduxToolkit #AsyncProgramming #ReactDevelopers #SoftwareEngineering #LearningInPublic #WebDevCommunity

Remember when every API started with a controller folder? Those days might be numbered. Hono's documentation has a bit of a silent killer in its best practices which make it clear: they don't belong in modern JavaScript apps. It's an interesting stance. Controllers used to feel like the gold standard for structuring HTTP logic. They brought order, separation, and a sense of architecture. But maybe that era's ending? In Conversation Piece's debut alongside the Hustle Hammer series, I dig into whether the controller pattern still earns its keep in 2025 - or if frameworks like Hono are showing us a better way to think about routing and request handling. Give it a read and tell me where you stand: are controllers still part of your toolkit, or are you moving on? https://lnkd.in/e8tNRsYw

Day 10, and I’ve moved on from simple lists (arrays) to managing complex data with JavaScript Objects! If arrays are just numbered lists, objects are like personalized file folders that let you organize information using descriptive names (keys) instead of numbers. This is how you structure anything with multiple properties like a user profile or a product all inside one clean variable. I learned the two main ways to grab information from them: Dot Notation (e.g., user.name) and Bracket Notation (e.g., user['email']). It feels like the final piece of the data organization puzzle! When you’re dealing with objects in JavaScript, when is it necessary or better to use Bracket Notation over Dot Notation?" #objects #javascript #31dayschallenge #growth #frontend #webdevelopment

Context API vs. Redux: Stop the Confusion.  Here’s the 2-minute rule that can help. Choosing between React's built-in Context API and the popular Redux library is a common dilemma. The key is to think about scale and frequency. ⤷Use Context API for: -Simple, infrequent updates, like a dark mode toggle or a logged-in user's name. -Avoiding "prop drilling" on a small-to-medium scale. -When you prefer a lightweight, built-in React solution with less setup. ⤷Use Redux for: -Large, complex applications with state that changes frequently. -Centralizing a single "source of truth," like a shopping cart or dashboard data. -Debugging complex state issues with powerful DevTools, which Context lacks. -Predictable state updates with a structured flow of actions and reducers. ⤷Username & Notification Example: →You have two states:    -Username: Rarely changes    -Notifications: Changes frequently →With Context: If you put both in one context, every time notifications update, all components showing the username re-render too.  This is inefficient. To fix it, you must split your contexts, adding complexity. →With Redux: Redux lets components subscribe only to the state they need. The component showing notifications subscribes to notifications.  Lot of components showing the username do not re-render when a notification arrives. ⤷The takeaway:  -Context is perfect for static or low-frequency global data.  -Redux shines when your state is dynamic, shared, and heavily updated. ⤷Your take:  -Have you ever migrated from Context to Redux?  -What was your sign that it was "time for a cannon"?

Day 12 of JS series - by Rohit Negi What I learned: ✅ forEach() – Iterates over every element in an array. ✅ filter() – Filters elements from an array based on a specific condition and returns a new array. ✅ map() – Transforms each element of an array and returns a new array. ✅ reduce() – Reduces an array to a single value (of any data type). ✅ Set – A data structure that stores unique values. ✅ Map – A data structure that stores key-value pairs, where both keys and values can be of any data type. #LearnInPublic #JavaScript #WebDevelopment

In simple terms, polling means automatically fetching data from the server at regular intervals, keeping your UI fresh and real-time. What this does: ➤ Automatically refetches data every 5 seconds ➤ Keeps your app synced with real-time updates ➤ No manual reloads needed! 💡 Bonus Tip: You can even stop polling when the browser tab is inactive by setting refetchIntervalInBackground: false - great for optimizing performance. So the next time you see live dashboards or dynamic analytics updating instantly, remember — it’s Polling making it happen! 🔥 #ReactJS #ReactQuery #FrontendDevelopment #WebDevelopment #JavaScript #ReactHooks #Coding #TechLearning

We’ve all been there debugging a perfectly fine API response... only to realize your data is failing validation because of a few invisible spaces. These trailing spaces can silently break string comparisons, UI bindings, and even backend validations. So, I wrote a simple recursive utility in JavaScript to clean them deeply. 🧹 𝗪𝗼𝗿𝗸𝘀 𝗳𝗼𝗿: Nested objects Arrays Deeply nested strings 𝗜𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄𝗲𝗿𝘀 𝗹𝗼𝘃𝗲 𝗮𝘀𝗸𝗶𝗻𝗴 𝗮𝗯𝗼𝘂𝘁: Recursion Object traversal Data normalization or deep cloning This question can easily appear as: “Write a function to remove spaces from all string values in a nested object.” #JavaScript #WebDevelopment #CodingTips #Frontend

👨💻 Tired of scattered console.log() everywhere? Let’s talk about why you should create your own logger.js in React — and how it can instantly make your debugging cleaner, safer, and more professional. 🔍 Why use a Logger instead of console.log()? In real-world projects, you don’t just log messages — you manage them. A proper logger helps you: ✅ Organize logs by level (info, warn, error, debug) ✅ Hide logs automatically in production ✅ Send logs to your backend or monitoring tools (Sentry, LogRocket, etc.) ✅ Maintain a consistent format across the team // src/utils/logger.js const isProd = process.env.NODE_ENV === "production"; const logger = { info: (...args) => !isProd && console.info("[INFO]", ...args), warn: (...args) => !isProd && console.warn("[WARN]", ...args), error: (...args) => console.error("[ERROR]", ...args), // keep visible debug: (...args) => !isProd && console.debug("[DEBUG]", ...args), }; export default logger; Use it anywhere: import logger from "../utils/logger"; logger.info("App started"); logger.debug("User data fetched"); logger.error("Failed to load dashboard", error); 🎯 Benefits: No random logs in production Easier debugging in dev mode Professional code structure Easy to integrate with monitoring tools #ReactJS #JavaScript #WebDevelopment #CleanCode #FrontendTips #loggerjs #Developers #CodingBestPractices

Most developers use localStorage and sessionStorage without really knowing the difference. I was the same — until one bug forced me to actually read the docs. Here’s the difference 👇 🧠 localStorage - Data persists even after the browser is closed. - Great for saving user preferences, themes, or tokens that don’t expire. ⚙️ sessionStorage - Data clears once the tab or window is closed. - Perfect for temporary data like form states or one-session inputs. Both store data as key-value pairs in the browser — but persistence changes everything. I learned one rule from that bug: → “Use sessionStorage when you want memory. → Use localStorage when you want permanence.” Small detail. Big difference. #javascript #webdevelopment #frontend #softwareengineering #learnbybuilding #reactjs

💡 structuredClone() vs JSON.parse(JSON.stringify()) Both are used for deep copying objects in JavaScript, but they’re not the same. 🧠 structuredClone() Creates a true deep copy (recursively copies nested data). Supports complex types: Date, Map, Set, Blob, etc. Handles circular references safely. Faster and more reliable. const clone = structuredClone(obj); ⚠️ JSON.parse(JSON.stringify()) Works only for simple JSON-safe data. Loses functions, Dates, Maps, Sets, and Symbols. Crashes on circular references. ✅ Use structuredClone() whenever available (modern browsers & Node 17+). Use the JSON trick only for plain, simple data. #JavaScript #WebDevelopment #Frontend #DeepCopy #CodingTips
