Mastering the Update in CRUD with FastAPI and React

🧠 New Blog: **React Hooks for Library Authors**  Most developers know `useState` and `useEffect`, but React also provides hooks specifically for library creators: - `useImperativeHandle` → expose controlled APIs - `useDebugValue` → improve DevTools readability - `useSyncExternalStore` → safely integrate with external state If you’re building reusable React libraries, these are your secret weapons.  Full guide ➜ https://lnkd.in/d5naXswb   #React #SoftwareEngineering #FrontendDevelopment #OpenSource

HNG Tech The Video Version of my post 📯 🚀 Just Built My First HNG task RESTful API with External API Integration! I recently completed a backend challenge that pushed me to level up my Node.js skills. Here's what I built: ✨ The Project: A clean REST API endpoint that serves my profile information combined with real-time cat facts from an external API. Simple concept, but packed with learning! 🛠️ What I Built: - GET /me endpoint returning JSON data - Live integration with Cat Facts API - Dynamic timestamps (ISO 8601 format) - Graceful error handling with fallback strategies - Full CORS support and request logging 💡 Key Challenges & Solutions: 1️⃣ External API Reliability Problem: What if the cat facts API goes down? Solution: Implemented timeout handling (5s) and fallback messages. The app never breaks - it just returns a default fact. 2️⃣ Data Freshness Challenge: Ensure both timestamp and cat fact update on EVERY request Solution: No caching anywhere. Each request triggers a fresh API call and timestamp generation. 3️⃣ Code Organization Why it matters: Messy code = maintenance nightmare My approach: MVC architecture with separate layers for routes, controllers, and services. Each file has one job. 🏗️ Tech Stack: - Node.js & Express.js - Axios for HTTP requests - Deployed on [Your Platform - Railway/Azure/etc.] - GitHub for version control 📊 What This Taught Me: ✅ External API integration isn't just about making requests - it's about handling failures gracefully ✅ Error handling is as important as the happy path ✅ Modular code = easier testing & scaling ✅ Environment variables are your friend in production ✅ Deployment is a skill in itself (learned about Azure/Railway/etc.) 🔗 Try it yourself: [https://lnkd.in/dVtjREi4 💻 Source code: [https://lnkd.in/dqU9xaEg] This project forced me to think like a backend engineer - not just "does it work?" but "what happens when things go wrong?"

You know, when you need to 𝐟𝐞𝐭𝐜𝐡 𝐝𝐚𝐭𝐚 from 𝐭𝐡𝐫𝐞𝐞 𝐝𝐢𝐟𝐟𝐞𝐫𝐞𝐧𝐭 𝐀𝐏𝐈𝐬, but they all need to finish 𝐛𝐞𝐟𝐨𝐫𝐞 you can 𝐫𝐞𝐧𝐝𝐞𝐫 the 𝐩𝐚𝐠𝐞? Enter 𝐏𝐫𝐨𝐦𝐢𝐬𝐞𝐬 and their incredible 𝐜𝐨𝐦𝐛𝐢𝐧𝐚𝐭𝐨𝐫 𝐦𝐞𝐭𝐡𝐨𝐝𝐬—the superheroes of modern JavaScript! 𝐏𝐫𝐨𝐦𝐢𝐬𝐞𝐬 handle the "𝐰𝐡𝐞𝐧 𝐭𝐡𝐢𝐬 𝐞𝐯𝐞𝐧𝐭𝐮𝐚𝐥𝐥𝐲 𝐡𝐚𝐩𝐩𝐞𝐧𝐬, 𝐝𝐨 𝐭𝐡𝐚𝐭" logic, keeping your code clean. But the real magic lies in their combinators, which let you orchestrate multiple async operations like a pro conductor: 𝐏𝐫𝐨𝐦𝐢𝐬𝐞.𝐚𝐥𝐥(): This is your "𝐀𝐥𝐥 𝐨𝐫 𝐍𝐨𝐭𝐡𝐢𝐧𝐠" strategy. Perfect for fetching data that must all succeed (e.g., getting a user's profile, settings, and friend list simultaneously). If one fails, they all fail fast. 𝐏𝐫𝐨𝐦𝐢𝐬𝐞.𝐫𝐚𝐜𝐞(): Need the 𝐟𝐚𝐬𝐭𝐞𝐬𝐭 𝐫𝐞𝐬𝐩𝐨𝐧𝐬𝐞? This method "races" multiple promises and returns the result of the first one to resolve or reject. Great for redundant server calls or a timeout mechanism. 𝐏𝐫𝐨𝐦𝐢𝐬𝐞.𝐚𝐥𝐥𝐒𝐞𝐭𝐭𝐥𝐞𝐝(): Want to 𝐤𝐧𝐨𝐰 𝐭𝐡𝐞 𝐨𝐮𝐭𝐜𝐨𝐦𝐞 𝐨𝐟 𝐞𝐯𝐞𝐫𝐲 𝐩𝐫𝐨𝐦𝐢𝐬𝐞, regardless of success or failure? Use this! Ideal for non-critical background tasks like logging or status updates where you need a full report. These methods literally turn callback code into elegant, readable async flows. They've saved me countless hours of debugging! 𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 when to use 𝐚𝐥𝐥(), 𝐫𝐚𝐜𝐞(), 𝐨𝐫 𝐚𝐥𝐥𝐒𝐞𝐭𝐭𝐥𝐞𝐝() is a true mark of an experienced developer. ➡️ 𝐅𝐨𝐥𝐥𝐨𝐰 𝐦𝐞 for more content on clean code, JavaScript, and developer insights! 👍 𝐒𝐡𝐚𝐫𝐞 this post if you found this breakdown helpful! 🔄 𝐑𝐞𝐩𝐨𝐬𝐭 to help a fellow developer tame their async tasks! #JavaScript #Promises #AsyncAwait #WebDevelopment #ProgrammingTips #CleanCode #TechSkills

𝐓𝐲𝐩𝐞𝐒𝐜𝐫𝐢𝐩𝐭 𝐠𝐢𝐯𝐞𝐬 𝐲𝐨𝐮 𝐭𝐲𝐩𝐞 𝐬𝐚𝐟𝐞𝐭𝐲... 𝐮𝐧𝐭𝐢𝐥 𝐫𝐮𝐧𝐭𝐢𝐦𝐞. You define perfect TypeScript interfaces for your API responses. Your IDE shows no errors. Your build passes. Everything looks perfect. Then production happens: the API returns null instead of an object. A number comes back as a string. An optional field is suddenly required. Your app crashes. TypeScript only checks types at compile time. It can't protect you from external data. 𝐓𝐡𝐚𝐭'𝐬 𝐰𝐡𝐞𝐫𝐞 𝐙𝐨𝐝 𝐜𝐨𝐦𝐞𝐬 𝐢𝐧. Zod lets you define schemas that validate data at runtime: → API responses actually match your types → Form inputs are validated before processing → Environment variables are checked on startup → Database queries return expected shapes You write one schema, and Zod automatically: ✓ Validates the data structure ✓ Infers TypeScript types ✓ Generates helpful error messages ✓ Transforms data if needed No more runtime surprises. No more try-catch blocks everywhere. No more "undefined is not an object" errors in production. Your TypeScript types finally work with real-world data, not just in your IDE.

🚀 Mastering res.on() Events in Node.js – The Hidden Power Behind Streams! Ever wondered how you can listen to the lifecycle of an HTTP response in Node.js? That’s where res.on() comes in — it lets you react to key response events such as when data is being sent, finished, or when something goes wrong. Let’s break it down 👇 🧠 What is res.on()? In Node.js, every HTTP response object (res) is an EventEmitter, which means we can subscribe to events like: 'data' → when data chunks are being written 'end' → when all data is sent 'error' → when something goes wrong during transmission 'close' → when the connection closes (even abruptly) This gives developers fine-grained control over network responses — a must for performance monitoring, debugging, and logging. 💡 Why Use res.on()? ✅ Monitor outgoing responses — useful for logging and analytics. ✅ Handle premature disconnects — detect if clients drop off. ✅ Improve debugging — get detailed insights into request/response flow. ✅ Enhance performance tracking — measure when responses actually complete. 🎯 Key Takeaway res.on() turns your Node.js responses into observable events — empowering you to build robust, reliable, and production-grade servers with deeper control over network behavior. #NodeJS #BackendDevelopment #WebPerformance #FullStackDevelopment #JavaScript #LearningInPublic

⚡ 𝗡𝗼𝗱𝗲.𝗷𝘀 𝗦𝘁𝗿𝗲𝗮𝗺𝘀 𝗤𝘂𝗶𝗰𝗸 𝗖𝗵𝗲𝗮𝘁 𝗦𝗵𝗲𝗲𝘁 𝗳𝗼𝗿 𝗗𝗲𝘃𝘀 ⚡ If you’ve ever worked with large files or data pipelines in Node.js, you’ve probably heard about Streams but maybe not fully used their power. 🧠 𝙒𝙝𝙖𝙩 𝙖𝙧𝙚 𝙎𝙩𝙧𝙚𝙖𝙢𝙨? Streams let you read/write data in chunks instead of loading it all at once. This makes your app faster and memory efficient, especially for big files or APIs. 🔹 𝟰 𝙏𝙮𝙥𝙚𝙨 𝙤𝙛 𝙎𝙩𝙧𝙚𝙖𝙢𝙨  • Readable → for reading data (e.g., fs.createReadStream)  • Writable → for writing data (e.g., fs.createWriteStream)  • Duplex → both read and write (e.g., sockets)  • Transform → modify data while streaming (e.g., compression, encryption) 𝘤𝘰𝘯𝘴𝘵 𝘧𝘴 = 𝘳𝘦𝘲𝘶𝘪𝘳𝘦("𝘧𝘴"); 𝘤𝘰𝘯𝘴𝘵 𝘳𝘦𝘢𝘥𝘢𝘣𝘭𝘦 = 𝘧𝘴.𝘤𝘳𝘦𝘢𝘵𝘦𝘙𝘦𝘢𝘥𝘚𝘵𝘳𝘦𝘢𝘮("𝘪𝘯𝘱𝘶𝘵.𝘵𝘹𝘵"); 𝘤𝘰𝘯𝘴𝘵 𝘸𝘳𝘪𝘵𝘢𝘣𝘭𝘦 = 𝘧𝘴.𝘤𝘳𝘦𝘢𝘵𝘦𝘞𝘳𝘪𝘵𝘦𝘚𝘵𝘳𝘦𝘢𝘮("𝘰𝘶𝘵𝘱𝘶𝘵.𝘵𝘹𝘵"); 𝘳𝘦𝘢𝘥𝘢𝘣𝘭𝘦.𝘱𝘪𝘱𝘦(𝘸𝘳𝘪𝘵𝘢𝘣𝘭𝘦); ✅ Reads input.txt in chunks ✅ Writes to output.txt ✅ No memory overload 🚀 𝙋𝙧𝙤 𝙏𝙞𝙥𝙨 Always handle error events → .on('error', console.error) Use pipeline() from stream module for cleaner error handling Perfect for large JSON, CSV, or log processing 💬 𝐒𝐭𝐫𝐞𝐚𝐦𝐬 𝐚𝐫𝐞 𝐥𝐢𝐤𝐞 𝐰𝐚𝐭𝐞𝐫 keep data flowing smoothly, not flooding memory.

After 10 years bouncing between Rails, Express, Phoenix, and just about every web framework out there, I'm building something different. Tracks: a Rails-inspired Go framework designed for rapid development with AI assistance. What makes it different: • Terminal UI for development - real-time logs, code generation, and database inspection in one place • AI integration via Model Context Protocol - your assistant can generate features, analyze code, and debug alongside you • Zero runtime dependencies - you own all the generated code, no framework lock-in • Built with HTMX, templ, SQLC, and modern Go tooling The code generation is inspired by music production (I'm a bassist who codes). You compose your app from separate "tracks" that work in harmony - migrations, services, handlers, templates. We're in Phase 0, building in public. If you've been frustrated by endless boilerplate and want to see how AI can enhance developer workflows, I'd love your feedback. Read more: https://lnkd.in/gvCJdf2S #golang #webdev #opensource #htmx
