🚀 Announcing Watt 3: The Future of Node.js Application Development is Here After months of intense development and 15 breaking changes, I'm thrilled to announce that Watt 3 is now available. This isn't just an incremental update – it's a complete reimagining of how Node.js applications should be built, deployed, and scaled. Why This Release Matters We've been listening to the Node.js community for years. You told us about the pain points: slow sequential startups, complex TypeScript compilation, scattered tooling, and the operational overhead of modern application development. Watt 3 addresses every single one of these challenges. Game-Changing Features: 🔥 Parallel Everything: Applications that took 45 seconds to start now boot in 15. We've completely rewritten our startup logic to leverage parallel execution, dramatically reducing deployment windows and improving developer feedback loops. ⚡ Native TypeScript via Type Stripping: This is revolutionary. No more compilation. No more build steps. Node.js now strips types at parse time, giving you instant execution with zero overhead. Write .ts files, run them immediately. This is how TypeScript was meant to be used. 📊 Built-in Performance Monitoring: Yesterday, we shipped flamegraph generation directly into Watt. No external tools are needed; visualize your bottlenecks and optimize with confidence. Performance isn't optional in 2025. 🏗️ Architectural Clarity: We've renamed our core concepts for better understanding: - Stackables → Capabilities (the building blocks) - Services → Applications (what you deploy) - Composer → Gateway (because that's what it actually is) 🛠️ Unified Tooling: One CLI (wattpm) replaces the scattered tools, resulting in less cognitive load, better workflows, and happier developers. We've made bold decisions: - Node.js 22.18.0+ required (we're embracing the future) - Full ESM modules (but CommonJS is still supported) - Extracted client generation as Massimo (now powering companies like Spendesk) - Removed built-in log rotation (use the right tool for the job) Watt 3 represents our vision for Node.js development: zero-configuration deployments, production-ready by default, and complexity stripped away without sacrificing power. This is what happens when you listen to your community, remove what doesn't work, and double down on what does. The result? The most performant, maintainable, and future-ready Node.js application server we've ever built. Ready to experience the difference? Get started with: npx create-wattpm@latest I want to thank our incredible community for the feedback, bug reports, and contributions that made this release possible. Your input shaped every decision we made. What excites you most about Watt 3? I'd love to hear your thoughts and experiences as you start using it.

This is the story of how we improved the search experience at OLX Brasil in early 2024 by introducing semantic search. All major players in search are investing in hybrid approaches, because they’re not only proven to deliver better results, but also offers better scalability for product development by avoiding manual tuning of lemmatization, synonyms, and other linguistic rules. Incredible work with Daniel Correa Araujo, Raphael Pinheiro, Paulo Henrique da Silva, Claudia Bozza (ela/she), José Hisse Cabral e Denilson Limoeiro Júnior https://lnkd.in/dNgirbps

🆕 Let's rewrite everything in GostLang!! Finally something that is better than Scala, Kotlin, Go, Rust, all combined, 5x more performance, the bestest of the code APIs; AI powered. ☕️ GostLang isn't real. What we're missing, is that 99% of existing applications are not suffering from extreme performance issues, that justifies adopting a new tech with a whole new set of problems. Most applications still struggle with shaping its architecture in a scalable way; generally a well-designed DB, Queue/Async flow and any back-end language will take things, very far. Add a cache and object store, OLAP and suddenly you can scale this much further. 🐘 In a way, I think we all get excited about the possibilities of new tech, but we're forgetting that solving business needs is the key goal, and it explains why stacks on Python/PHP are so popular, still many people hate that. It doesn't mean things shouldn't be built in a way they can't evolve, but it's important to understand the moment each technology investment comes to the table. Let's say no to language wars, as long as we're on this battle, the industry is losing. 🪩 I felt like Friday was a good day to break from all the Data Streaming talk, enjoy your weekends!

🔐 Beyond HTTPS — How I Secured .NET APIs for 40,000+ Users with Azion Let me tell you — securing APIs is more than just adding HTTPS. It’s about protecting your users, your data, and your business. In one of my cloud projects, I built an API that serves over 40,000 users, and I made sure it was fast, secure, and resilient. How? With a collaborative approach, working alongside the Azion team and the client’s infrastructure team. ⸻ ✅ 1. Authentication & Authorization (API-Level Security) • 🔑 JWT (JSON Web Token): Secure, stateless authentication for APIs. • 🔒 OAuth 2.0 + Microsoft Identity: For secure enterprise login. • 📝 Role-Based (RBAC) + Policy-Based Authorization: Fine-grained access control. • 🔎 Claims-Based Access: Dynamic permissions based on user data. ⸻ ✅ 2. Edge Security with Azion (Protecting 40,000+ Users) But we didn’t stop there — together with the Azion team and the client’s infrastructure team, we added: • 🛡️ Edge Firewall: Blocking malicious traffic (DDoS protection, IP restrictions). • 🔎 WAF (Web Application Firewall): Protecting against OWASP Top 10 threats (SQL Injection, XSS). • 🔁 Reverse Proxy: Securely routing traffic to the APIs, hiding their real IPs. • 🔒 SSL Offload: Azion managed SSL/TLS, so I didn’t have to worry about certificates. • 🚀 Edge Caching: Speeding up static content delivery (CDN). • 📊 Real-Time Monitoring: Detecting and tracking traffic anomalies. ⸻ ✅ 3. Monitoring & Visibility Because security without visibility is just hope: • 📊 Application Insights (Azure): Complete visibility on API performance and errors. • 📝 Structured Logging (Serilog): JSON logs with full context (user, request, response). • 🔎 Real-Time Alerts: Detecting unusual behavior and notifying instantly. ⸻ 💡 Real-World Impact: • Secured over 40,000 users with JWT and Microsoft Identity. • All traffic passed through Azion, providing: • 🔒 SSL offload (Azion managed HTTPS). • 🛡️ WAF (blocking malicious requests at the edge). • 🔁 Reverse Proxy (hiding API endpoints). • Static content was cached at the edge, improving performance. • Monitoring with Application Insights for complete visibility. ⸻ 🚀 Why this worked: • ✅ Secure: Only authorized users access the API. • ✅ Fast: SSL offload + CDN with Azion. • ✅ Resilient: Attacks are blocked at the edge. • ✅ Scalable: 40,000+ users with zero downtime. • ✅ Visible: Full monitoring with Application Insights. ⸻ ✨ This wasn’t just my work — it was a collaborative success, with expertise from the Azion team and the client’s infrastructure team. 👥 Follow me for more real-world .NET and cloud solutions. #dotnet #api #security #cloudcomputing #jwt #azure #applicationinsights #azion #reallifecode #devlife #linkedinbr
