🗣️ Talks
➡️ Improving the Code Coverage and the Unit Test Cases with JEST in React Apps by Ajinkya Chanshetty
In this session, we will break down the concept of code coverage, explore effective ways to improve it, and discuss common pitfalls to avoid. We will share practical tips for optimizing unit tests, leveraging the JEST framework, and integrating coverage checks into your CI/CD pipeline. Strong code coverage is not just about statistics; it’s about catching bugs early, reducing regressions, and building confidence with every code change.

➡️ How We Built an Agentic Crew in TypeScript by Khadija Al-Selini and Nkechi Anyanwu
Multi-agent AI frameworks are everywhere right now — OpenAI Swarm, CrewAI, Langflow — but most of them are built Python-first. Meanwhile, a huge chunk of AI startups (60–70% in YC, by some counts) are building in TypeScript. And honestly, spinning up a whole Python backend just to leverage some of these frameworks didn’t feel worth it.
In this talk, we’ll walk through how we approached building a multi-agent AI system in TypeScript — by focusing on the core principles behind these frameworks and building something similar that fits the JS stack.

➡️ Server Components Wars: PHP Strikes Back by Edoardo Dusi
Server Components is a new pattern for the JavaScript world, but in this lightning talk, you'll see how easy it is to understand if we compare it to another old web language, one that shaped web development as we know it: PHP!
