Free LLMs in the Browser: Building with Chrome’s Built-In AI
Learn how to build private, offline, and free web apps using the new built-in Chrome and Edge On-Device AI APIs. The browser just became an local inference runtime, and nobody sent you a memo! Imagine running a ~4 GB instruction-tuned language model directly on your user's device with zero per-request token costs, zero network latency, zero data egress, and full offline support. In this video, we pull back the curtain on the web’s new built-in AI platform. We’ll run through the entire JavaScript API surface layer—including LanguageModel (Gemini Nano), Summarizer, Translator, Multimodal vision, and the upcoming WebMCP standard—proving everything live with the DevTools network tab completely empty. If you are a web developer or software architect looking to build ambient, real-time AI features that were economically impossible 18 months ago, this deep dive is for you.

🔥 Generative UI: The Future of Frontend (And Why You Should Care) / Daniel Ostrovsky
From https://summit.reversim.com/
November 14, 2025
🔥 Generative UI: The Future of Frontend (And Why You Should Care) - DevConf.CZ 2025
Speaker(s): Daniel Ostrovsky This talk is all about Generative UI. AI-driven user interfaces that actually adapt to users in real time. No more static, one-size-fits-all UIs. We’re talking about apps that think, respond, and evolve based on what users need. But here’s the catch: if you’re still building UIs like it’s 2020, you might be in trouble. We’ll dig into why modular designs (like Micro-Frontends) are the key to making AI-ready web apps, what skills frontend devs need to pick up right now, and how to work with AI instead of getting left behind. --- Full schedule, including slides and other resources: https://pretalx.devconf.info/devconf-cz-2025/schedule/

Micro-Frontend Architecture and Module Federation | Daniel Ostrovsky | Angular Tiny Conf 2023
The micro-frontend architecture is attracting more and more developers, and module federation is a great addition to this architectural pattern. And as with any new technology, new questions are raised. Let's take real-life examples and live coding to answer the following but not limited to: how we should divide apps and whether there are specific criteria to separate them. Is my project suitable for the Micro-Frontend at all? When should I use Micro-Frontend and when Module Federation? And some other questions. ---------------------------------------------------------------------------------------------------------------------- About Angular Tiny Conf Angular is the beloved framework to thousands of developers around the world and has lately been moving at a very fast pace.

Daniel Ostrovsky - Full Stack is dead, long live the Full Cycle! "VinnytsiaJS - Online Thursday #5"
Join to Discord Chat: https://discord.gg/euzddDk Full Stack is dead, long live the Full Cycle! - Daniel Ostrovsky When “time to market” is critical. When bug fixing on production can’t take longer than a couple of hours. And it doesn’t matter if we are talking about a large company or a small startup, a new reality more often requires developers/teams to be a “Full Cycle”, - design, development, test, deploy, operate, and support. Let’s talk about the past, present and why ‘Full Cycle’ is a future of Web Development. I think it’s highly important to stay tuned not only with the latest development technologies and trends but also with latest development models.

How to adopt UX/UI in Angular application according to user’s permissions.
In many projects, there are authentication processes (more or less). Many “best practices” were written in all known technologies, and so on and so forth. But what happens after the user makes the login? After all, he, by far, cannot do everything. How to define what he can see and what he cannot. What buttons he has the right to click on, and what to change, create and delete. In this talk, I want to consider the approach to solving these problems in a web application.

Special Angular-IL Meetup with Michael Hladky | 19.8.20
Save the date for a special meetup with Nir Kaufman, Daniel Ostrovsky aaaand..... Michael Hladky!! Daniel Ostrovsky Full-Stuck RunTime type validation --------- How to ensure type validation of data coming from external sources? “Runtime boundaries type validation” or “full stuck type-safe”, - all this talking about the ability to validate types of data coming from external sources. It can be any API or WebHook Call, third-part form validation, DB queries results or file content (such as JSON or CSV). Let’s see how can we define runtime types for the expected data, that can be validated while the application is running, to create a smooth developer experience with strong assurances of correctness at build-time. Michael Hladky Fully Zone-Less - High-Performance Angular applications in post IVY --------- The async pipe is boring! Understand the guts of Angulars change detection and why zone.js is your biggest enemy. Learn the trick on template bindings, component rendering, and where you pay the biggest price. As the tip of the iceberg, you will learn how to identify and avoid blocking UIs by analyzing flame charts and leverage task scheduling. In the end, you will be able to build applications with zone-less performance even in a zone-full environment. Nir Kaufman 15 minutes of Angular - Patterns & Techniques --------- Let's learn something new! Each session I will dive into an Angular feature, technique, or API. I'll focus on understanding the problem, and how to come up with a practical solution - the Angular way :) Tips and best-practices included. At the end of the meetup we will raffle 2 Jetbrains Licenses and a free ticket to AngularUP!

Web Development meets DevOps. Session #1 (HEB)
The number of manuals/tutorials on how to start programming in Angular / React / VueJs rolls over. After we have developed our great, highly innovative and extremely useful application, what's next? How to show it to the world without spending too much money? Instances, serverless or static websites? What tools are available for Continuous Integration/Delivery? And what about SEO? How does Google crawl a single page app? Does new evergreen-googlebot make our life easier? Server-Side rendering VS Pre-Rendering? Or is there another option? We will take some prebuilt app and deliver it to the world, by answering all the questions above. ********************* Session #1 will cover the following topics: ********************* - What is DevOps (some history) - Why we (FrontEnd developers) should care - Intro into the World of Containers - Hello World - Docker - Serve our static build from Docker |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| *** Prerequisite: 1) Machine with Docker installed: - macOS https://docs.docker.com/docker-for-mac/install/ - Linux-based: https://runnable.com/docker/install-docker-on-linux - Windows: https://docs.docker.com/docker-for-windows/install/ 2) Docker Hub account: https://hub.docker.com/signup 3) A good mood and willing to learn. https://github.com/danduh/web-devops-workshop

TS-Conf - Fall in love with TypeScript decorators
Here is a video of my talk from TS-Conf (Oct-2019). Google Slides: https://docs.google.com/presentation/d/1b5rPEaumNUEmh361he_mYnbLrpZniAtRl0JapGtigjc/edit?usp=sharing Decorators is one of the most underrated features in TS. At the same time is one of the most life-changing features. Once you get it your life will never be the same. We will start from basics definitions and go all the way to advanced real-life examples and use cases. Decorators are incredibly cool. They allow you to describe meta data directly in the class declaration, grouping everything in one place and avoiding duplication. Terribly addictive. Once having tried, you will use it forever However the decorators in TypeScript are not as simple as we would like. Working with them requires some skills. In this talk we will try to cover: Prologue Decorators in TC39 stage 2. meaning and when to expect. Babel Frameworks uses decorators (Angular, NestJS, MobiX…) Intro Descriptor and why it’s matter Simple logger decorator (live-coding) Method decorator Run time Validators (live-coding) memoize (livecoding) Method’s param decorator Why it’s so cool Real life examples (livecoding) Class Decorators (livecoding) Class Composition Class mixing Advances (optionally) Reflection, metadata Use cases and examples (livecoding) A coding is worth a thousand words….

Metaprogramming Part 2 - Class Decorators (Hebrew)
On 29/5/19, Daniel Ostrovsky gave a lecture about Class Decorators during a JavaScript Israel Meetup. Abstract: Decorators are part of proposal TC39 (stage 2), this means that sooner or later decorators will become a part of the JS. However, there is no need to wait! We can use decorators in TypeScript or with babel. Let's see how decorators can be used in metaprogramming and class composition, which gives you more flexibility by composing functionality to create new classes.
