"Engineering Interactive AI with WebMCP and MCP Apps" 🤖 The era of "text in, text out" AI is ending. We no longer want LLMs that just talk. We need them to act, render and integrate seamlessly into the web. At iJS Munich, Gil Fink closed the final conference day by showing how WebMCP and MCP Apps bridge that gap, turning AI from a chat window into a real part of your web application. ⚡ The perfect finale for an Agentic Web Week. Thank you, @Gil Fink! 👉 Full Day 4 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #WebMCP #MCP #AgenticAI #JavaScript

"Performance Tuning for EVERY Frontend Stack" 🏎️ Products get more complex, tech stacks keep growing and the framework landscape is more fragmented than ever. Giving performance advice that works everywhere seems impossible. At iJS Munich, Peter Kröner proved it isn't: practical frontend performance techniques that apply no matter which framework you build with. ⚡ Thank you, @Peter Kröner! 👉 Full Day 3 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #WebPerformance #Frontend #JavaScript #WebDevelopment

"Modularizing and Modernizing Legacy Software" 🧱 Starting from a clean slate is one thing. Inheriting a "monolith" or a "big ball of mud" is another, and that's the reality for most teams. At iJS Munich, Henning Schwentner showed how to bring order to chaotic legacy architectures: step by step, without a risky big-bang rewrite. 🛠️ Two sessions, one packed day. Thank you, @Henning Schwentner! 👉 Full Day 3 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #LegacyModernization #SoftwareArchitecture #DDD #JavaScript

"Chatless AI: Developing Real-Time Language Interfaces for Web and Mobile" 🎙️ No prompting. No waiting. Hands-free. Real-time models like GPT Realtime and Gemini Live are giving rise to a new generation of interfaces, where speech becomes an instant, low-latency way to interact with software. At iJS Munich, Sascha Lehmann showed how to build these real-time language interfaces for web and mobile, and what changes when the chat window disappears. ⚡ Thank you, @Sascha Lehmann! 👉 Full Day 3 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #VoiceAI #RealtimeAI #UX #JavaScript

"AI-Friendly Architecture Is Human-Friendly Architecture" 🏛️ AI coding assistants can generate features, refactor code and explain complex logic in seconds. Yet how well they work varies dramatically from one codebase to another. The difference is rarely the model. It's the architecture. In the Day 3 keynote at iJS Munich, Henning Schwentner showed why the same principles that make code easy for humans to understand also make it easy for AI to work with, and why good architecture matters more than ever in the age of coding agents. 💡 Thank you, @Henning Schwentner! Henning is back at 14:30 with "Modularizing and Modernizing Legacy Software." 👉 Full Day 3 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #SoftwareArchitecture #AICoding #DDD #Keynote

"Mastering Task Management in JavaScript" ⏱️ Long-running JavaScript tasks block the main thread, and users feel it immediately: janky scrolling, frozen buttons, unresponsive interfaces. At iJS Munich, Gil Fink showed how to break up and schedule that work properly, so your UI stays smooth no matter how much is happening behind the scenes. 🧵 Thank you, @Gil Fink! And there's more: Gil closes the day at 17:00 with "Engineering Interactive AI with WebMCP and MCP Apps." 👉 Full Day 3 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #JavaScript #WebPerformance #Frontend #WebDevelopment

"Context Engineering: Stop Vibing, Start Shipping" 🎯 Many teams still use Claude Code, Codex and friends on a "let's try this AI stuff" basis. No shared workflow, no shared standards, and the quality of coding agents' output swings wildly from one developer to the next. At iJS Munich, Tobias Schlitt showed how context engineering changes that: giving agents the right context, consistently, so teams stop vibing and start shipping. 🚀 Thank you, @Tobias Schlitt! 👉 Full Day 3 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #ContextEngineering #AICoding #AgenticAI #JavaScript

"Production Incidents Without Data Loss: Lessons from Real Systems" 🚨 How do you build a system that processes millions of records every day and still doesn't lose data when production goes wrong? At iJS Munich, Nairi Harutyunyan shared hard-won lessons from real systems built with Node.js, Redis, Kafka and SQL databases: what fails, why it fails and how to design so your data survives when it does. 💪 Thank you, @Nairi Harutyunyan! 👉 Full Day 3 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #NodeJS #Kafka #Reliability #Backend #JavaScript

"Making React Apps Faster with WebGPU and WebAssembly" ⚡ When a React app gets slow, we reach for the usual tools: memoization, virtualization, lazy loading. But what if React isn't the bottleneck at all? At iJS Munich, Sylwia Laskowska opened Conference Day 3 by looking past the framework to the real culprit: heavy computation like processing large datasets and running complex calculations. Her answer? Move that work to WebGPU and WebAssembly and let the UI breathe again. 🚀 A great start to the final conference day. Thank you, @Sylwia Laskowska! 👉 Full Day 3 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #React #WebGPU #WebAssembly #Performance #JavaScript

"Security HTTP Headers: The Good, the Bad and the Ugly" 🛡️ Not long ago, web browsers were considered the #1 security risk on the web. Today, they are the last line of defense. At iJS Munich, Christian Wenz showed how modern, secure web applications use HTTP headers to strengthen their security posture, and which headers really help, which ones don't and which can even hurt. 🔐 A few lines of configuration, a big difference in protection. Thank you, @Christian Wenz! And there's more: Christian is back at 15:45 with "Web Application Security, Up-To-Date: The 2025 OWASP Top Ten." 👉 Full Day 3 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #WebSecurity #HTTPHeaders #AppSec #JavaScript

"Professional Agent Development in Practice: A Deep Dive into LangChain" 🤖 Most AI tutorials stop at the "Hello World" of chatbots. Our LangChain bootcamp starts where they end. At iJS Munich, Nir Kaufman kicked off a full day of hands-on training on building, optimizing and scaling production-ready AI agents with LangChain. Laptops open, code running, real agents taking shape. 💻 Thank you, @Nir Kaufman, for leading the way into agent development! 👉 Full Day 3 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #LangChain #AIAgents #AgenticAI #JavaScript

"The UX of Smart AI Glasses: Live Demo on Stage" 👓 What if a speaker didn't just talk about AI wearables, but wore them on stage? That's exactly what Christian Kuhn did to close Conference Day 2 at iJS Munich. He threw away the slide deck and let the technology speak for itself, running his entire presentation through open-source AI smart glasses, live and unscripted. A brilliant way to show what designing for AI-first, screenless interfaces really means: new interaction patterns, new UX challenges and a whole new way of thinking about how people use technology. 🤯 The perfect finale to a packed second conference day. Thank you, @Christian Kuhn! 💛 👉 Full program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #SmartGlasses #AI #UX #Wearables #JavaScript

"Understanding Modern Identity: From Login Basics to OIDC and Passkeys" 🔑 OAuth, OIDC, JWTs, refresh tokens, passkeys… Authentication has changed dramatically, yet for many developers it still feels like a confusing mix of protocols, tokens and buzzwords. At iJS Munich, Roberto Gallea cut through that confusion with a clear, step-by-step journey through the major phases of identity on the web: from classic logins to OpenID Connect to a passwordless future with passkeys. The kind of session that makes a complex topic finally click. 💡 Thank you, @Roberto Gallea! 👉 Full Day 2 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #Security #OIDC #Passkeys #Authentication #WebDevelopment

"Are We Still Engineering Software, or Just Generating Code?" 🤔 Writing code has never been the hard part of software engineering. Understanding the problem, making the right trade-offs, managing complexity and building systems that last: that's where the real work happens. So what happens to all of that when AI writes the code? The Day 2 keynote at iJS Munich turned into an open discussion on AI, software craftsmanship and the future of development, with @Pauline Vos, @Stefan Priebsch, @Marcus Bointon and @Volker on stage and plenty of voices from the room joining in. 🎙️ No slides, no easy answers, just honest perspectives on what engineering judgment means when code is cheap and good decisions are not. Thank you to everyone on stage and in the audience for such a thoughtful conversation! 💛 👉 Full Day 2 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #SoftwareCraftsmanship #AI #SoftwareEngineering #JavaScript

"Post-Quantum Encryption: Why and How" 🔐 Quantum computing still sounds like the future. So why should developers care about it today? At iJS Munich, Marcus Bointon answered exactly that. Quantum computers threaten the encryption algorithms we rely on every day, and the data being collected now could be decrypted later. That's why post-quantum cryptography isn't a someday problem, it's a right-now one. Marcus walked the room through what's wrong with current encryption, what post-quantum cryptography changes, and what teams can start doing today to be ready. 🛡️ Thank you, @Marcus Bointon! And there's more: Marcus is back on stage at 14:45 with "PrAIvacy: Privacy and Security in AI Tools." 🤖 👉 Full Day 2 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #PostQuantum #Cryptography #Security #WebDevelopment

"Predictable UI, Decoupled Data: Rethinking React State with Fate" ⚛️ Network waterfalls, tangled data dependencies, components that know way too much about where their data comes from. Every React developer has been there. At iJS Munich, Nir Kaufman showed a different way in a code-first session on Fate: bringing patterns like view composition and strict data masking straight into your React stack, eliminating network waterfalls and pairing naturally with Async React features. Less theory, more code, and a lot of "I want to try this on Monday" energy in the room. 💻 Thank you, @Nir Kaufman! And if you missed it, Nir is back on stage at 16:00 with "Real-World Prompt Engineering: From Vibes to Metrics." 🎯 👉 Full Day 2 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #React #ReactJS #Frontend #JavaScript #WebDevelopment

"The Psychology of Overengineering" 🧠 Software rarely becomes complex because engineers are inexperienced. More often, it's the result of well-intentioned decisions made by smart teams trying to solve hard problems. At iJS Munich, Fabian Gosebrink explored the human side of complexity: why we add "just one more abstraction," why we build for problems we might have someday, and how good intentions slowly turn simple systems into hard-to-change ones. A talk that felt less like a lecture and more like a mirror for every developer in the room. 😅 Thank you, @Fabian Gosebrink! 💛 👉 Full Day 2 program: javascript-conference.com/mu… #IJSMunich #AgenticWebWeek #SoftwareArchitecture #Overengineering #CleanCode #JavaScript
