Ever had a user's shopping cart or preferences disappear when they move from your app to your marketing site? That's the friction caused by the browser's Same-Origin Policy. For years, developers have fought it with brittle iframe hacks and complex postMessage logic. There's a better way. This guide provides a modern, robust solution for cross-domain state sharing in React. We walk through a step-by-step tutorial to build a real-time, synced shopping cart that just works across shop.com and blog.com. This isn't a workaround; it's a superior architecture for modern multi-site applications. Read the full guide here: https://lnkd.in/eKGJaKxi

21-Day Coding Challenge: Day 13/21 - Building the Final Step of the Conversion Funnel: The Checkout Page. 💳🥳💻 Today, I completed the core e-commerce user journey by building the /order page. This is arguably the most critical page in the application, as a smooth and intuitive checkout process is key to conversion. 🚀✅👍 My #LearnInPublic focus for this final piece of the funnel: 🔹 Seamless Routing: Used react-router-dom to create the final navigation step from the cart to the order page. 🔹 Structured Data Collection: Built a clean, multi-field form to gather all necessary delivery information. 🔹 Mobile-First Checkout: The entire page was designed to be fully responsive from the start. A frictionless mobile checkout experience is non-negotiable and helps reduce cart abandonment. 🔹 Final Confirmation: The page includes a final summary of the cart totals, giving the user one last chance to review their order before payment. With this, the entire front-end flow from browsing ➡️ adding to cart ➡️ checking out is now complete and works great on both desktop and mobile. 🎉🌟📱. #21DayCodingChallenge #ReactJS #ReactRouter #FrontendDevelopment #eCommerce #UIUX Burle Sharma Prabin Kumar Nayak Shashank Shekhar Barik

🚀 Why Be Apart When We Can Merge? Recently, I built a cart merge feature in my e-commerce web app, Shooply. The idea was simple yet challenging: allow anonymous users to add items to their cart and seamlessly merge it with their active cart once they log in. At first, a lot of questions raced through my mind: 1️⃣ Where should I store the anonymous cart? 2️⃣ How long should it live? 3️⃣ What happens if a product promo is removed after the item is added? 4️⃣ How do I handle the cart merge itself? 5️⃣ How do I notify the user of this merge? After digging in, here’s how I solved each challenge: ✅ Where to store the anonymous cart I chose cookies instead of local storage or the database. This reduces unnecessary database congestion while keeping the cart session-dependent and lightweight. ✅ How long to store it As long as the browser session. Since cookies are tied to sessions, they expire naturally when the session ends. ✅ Handling product changes (like promo removal) Because the cart is cookie-based, it’s always available for recalculation whenever product data changes. ✅ Merging carts on login Once a user logs in, the anonymous cart (from cookies) is merged with their authenticated cart using a backend algorithm. A real-time notification is then triggered to inform the user. ✅ User notification After merging, I publish a message to an event bus (Kafka). A real-time service consumes this event and pushes a notification to the user via WebSocket. This feature was a fun challenge because it tested both system design thinking and user experience flow. For me, the real win wasn’t just writing the code ,it was designing the architecture to make the experience seamless. 💡 I’d love to hear from others: How would you approach anonymous-to-authenticated cart merging in your own projects? #Ecommerce #SystemDesign #WebDevelopment #Shooply #TechJourney

The hidden reason your Bubble app feels slow: If your app takes a few extra seconds to load or process things… it’s probably not your design. It’s your workflows. Most early Bubble builds run everything “on-page.” That means every time a user clicks something, Bubble does all the work right there — sending emails, updating records, calculating data. The fix? Move the heavy lifting to the backend. Backend workflows let your app do the hard work quietly, behind the scenes — so users see instant results while the system keeps processing in the background. If your Bubble app feels sluggish, it might just need smarter workflow architecture — not a rebuild. I can help you with that, just send me a DM!

Modularizing Apps for Faster Builds As projects grow, monolithic modules slow everything down. Modularization helps. Benefits I’ve seen: ✅ Faster incremental builds. ✅ Teams can work on isolated modules. ✅ Easier testing + reusability. Approach: ● Core module (networking, DB). ● Feature modules (login, payments, profile). ● Shared UI module. 💡 Splitting large codebases into modules was the single biggest boost to productivity in one of my apps. #Modularization #GradleTips #AndroidArchitecture

What You Need to Launch a Modern Web App: 1️⃣ Frontend (UI/UX) – The face of your app; where users interact 2️⃣ Backend (API & Logic) – The core engine powering your features 3️⃣ Authentication – Signup, login, logout, and user sessions 4️⃣ Database – Where all your data lives 5️⃣ Payments – Seamless and secure transactions 6️⃣ Security – Protect users and infrastructure 7️⃣ Notifications – Push, SMS, and email updates 8️⃣ Analytics – Track user behavior and performance 9️⃣ Hosting/Deployment – Bring your app to life online 💡 Every great web app is a mix of design, engineering, and problem-solving built layer by layer to serve users better.

Ever seen a beautiful house built without a plan for plumbing or electricity? It might look great, but it's not functional and will cost a fortune to fix later. The same principle applies to software development. The traditional way: Design the "face" (the website or app) first, then try to fit the "brain" (the backend logic) into it. This often leads to a rigid system that's difficult and expensive to change. Our approach is different. We build with an API-first strategy. 🧠 First, We Build the Brain (The API) The API (Application Programming Interface) is the central nervous system of your project. It handles all the data, business logic, and rules. It doesn't care what the user interface looks like; it just manages the core functions: creating users, processing payments, fetching product info, etc. 🎨 Then, We Build the Face (The UI) Once the brain is designed, we can build any number of "faces" that connect to it. This could be: A responsive website An iOS and Android mobile app A partner integration An internal admin panel Each "face" simply asks the central "brain" for the information it needs. Why does this save you money on scaling? ✅ Future-Proof Flexibility: Need a mobile app a year after your website launch? You don't need to rebuild your backend. Just create a new "face" that talks to the existing, powerful "brain." This cuts development time and cost dramatically. ✅ Faster Development: Your backend and frontend teams can work in parallel. While one team builds the API, another can build the user interface based on the agreed-upon API "contract." This gets your product to market faster. ✅ Omnichannel Ready: Your business logic is centralized and consistent, ensuring a seamless experience whether your customers are on your website, a mobile app, or even a kiosk. Building API-first isn't just a technical choice; it's a strategic business decision. It's about creating a robust, scalable foundation that grows with your business, not against it. #artificialintelligence #machinelearning #altezzacreativesolutions #altezzainfo #altezzasoftware

In today’s world of multi-platform applications(web, mobile, smart TVs) , a one-size-fits-all API doesn’t cut it anymore. That’s where BFF (Backend for Frontend) architecture steps in. 🔍 What is a BFF? A Backend for Frontend is a dedicated backend layer tailored to the needs of a specific frontend application or interface. Instead of one monolithic API serving all frontends, you create a lightweight, customized backend per frontend (e.g., one for mobile, one for web, etc.). Each BFF acts as a mediator between frontend and backend services. It aggregates and reshapes data and handles logic specific to the UI it serves 💡Problems BFF Solves? A mobile app needs smaller payloads and optimized responses due to limited bandwidth. A desktop web app may need richer data, more interactions per view. A single API often can't serve both efficiently. Frontend teams can deploy and iterate independently from backend teams. Each BFF can evolve at the pace of its frontend without impacting others. In a microservices architecture, frontends might need data from multiple services. BFFs can handle aggregation and orchestration, keeping the client light. 🧠 To summarize BFF is an enabler for clean architecture, faster delivery, and better user experience. It doesn't replace your core backend; it extends and adapts it to serve specific frontend needs—cleanly and efficiently. 🔁 Have you used BFFs in your architecture?
