CascadiaJS 🇺🇸 🇨🇦

CascadiaJS 2026 is a wrap! Thank you to our speakers, sponsors, staff, attendees and everyone who supported us along the way to make this event happen. Photos and talk videos will be published shortly ❤️ We put 💯 Blind Bird tickets for CascadiaJS 2027 on sale, grab one before they sell out and lock-in your spot for the best web + AI conference in the PacNW! 🌲 luma.com/cascadiajs-2027

If AI only learns from yesterday's ideas, who creates tomorrow's? @martypdx makes the case for building software that breaks new ground, and shares how to help AI work with innovation instead of reinforcing the status quo. youtu.be/_pUpE2WM2zw

A live-coded morning rave is a pretty memorable way to start a conference talk. 🪩 Watch as @amhinson shows how to build fast, private, task-specific AI tools with small local models, and why the right architecture matters more than simply calling the biggest LLM you can find. youtu.be/V_h_tMGgf6w

Will AI make programming languages irrelevant? 😲 Watch as @filipsodic argues the opposite: as AI writes more code, strong type systems become even more valuable. Learn why TypeScript isn't just surviving the AI era, it's becoming one of the best ways to capture intent, reduce bugs, and build better software. youtu.be/WxhlRSfyxjY

Everyone wants to build AI tools. The hard part is proving they actually help. Watch as Jeff Otaño shares how @Onebriefapp stopped chasing flashy demos, started measuring real outcomes, and used feedback loops to improve AI agents that fix production bugs. 🪲 youtu.be/LCKraOtFV-Q

AI may be changing software development, but it isn't replacing the need for junior developers. 🧑‍💻 Listen to Dylan Goings and learn why mentorship, diversity, and long-term knowledge transfer are more valuable than ever. youtu.be/S5XLYOsJ1u8

Just use JavaScript

🧩 Design systems can't solve every UI problem. Watch as @decompiled shares practical lessons for building shared components that scale across teams, with layered extensibility, sensible defaults, and escape hatches that keep both developers and products moving forward. youtu.be/haOndDHMGJQ

What happens when your "simple" API grows into an unmaintainable mess? 😅 This talk by @darius_cepulis explores the tradeoffs between configuration and composition, and why the right abstractions matter more than ever in the age of AI. youtu.be/dExasNlhVKM

What happens when AI agents use specs, not just prompts, to build software? Watch as @JI, co-founder of @Expo, introduces linked literate programming, a simple approach that keeps code, specifications, and intent in sync so AI can build more accurate, maintainable software. youtu.be/a8xYFd1ZLNQ

The best use of AI isn't writing code, it's helping you learn. 💡 Watch Daniel Mendoza's practical guide to mastering new frameworks by turning your AI assistant into a tutor instead of a code generator. youtu.be/foOOku3P9uQ

Ever click a button and wonder why your app freezes? 🤔 Check out this talk by @c_yatteau where she shows how web workers keep JavaScript apps responsive by moving CPU-intensive work off the main thread, with practical patterns for progress updates, cancellation, and debouncing. youtu.be/rh4RzLLPSis

Binge-watching this year's talk videos and getting serious FOMO? Don't miss out, join us in 2027! luma.com/cascadiajs-2027

@brandontroberts There will always be a home for Angular talks & workshops at CascadiaJS, if the community would like to join us in the PNW 🌲

End of an era 🫡 We're officially out of Angular conferences in the US 😭

CSS colors got a lot more powerful while most of us weren't looking. 🎨 In this talk @jdsteinbach demonstrates how features like light-dark(), relative colors, and contrast-color() can simplify theming, reduce design tokens, and make accessibility easier using capabilities built directly into modern browsers. youtu.be/gDq07OJBgiw

What if the future of software development isn't one AI agent, but hundreds? 🤖 🤖 🤖 In this talk @joelhooks explores agent swarms, harness engineering, AI-powered workflows, and why the real challenge isn't building smarter agents, it's designing systems that make the best use of human attention. youtu.be/SdgD1fI5lEw

🚨 Live to react to my last keynote in Seattle, @CascadiaJS to talk about JavaScript, Rust, and Web Development Link below

AI coding agents are a lot like eager interns: they'll build exactly what you ask for... even when it's not what you meant 😅 In his CascadiaJS 2026 keynote, @ErikCH of @awscloud explains how spec-driven development helps teams create better requirements, build more maintainable software, and get better results from AI coding tools. youtu.be/CGCLMky4OO8

JavaScript won the web. But more and more, when you peel back the covers, you see Rust 🦀 @FrancescoCiull4 opened Day Two of CascadiaJS 2026 by exploring why companies like Cloudflare, Discord, and Shopify are using Rust for performance-critical infrastructure, and where it fits in a modern web stack alongside JavaScript. youtu.be/1lgxqv1qWz4

Joe Duffy, Founder and CEO of @PulumiCorp, closed out Day 1 of CascadiaJS 2026 with a look at what happens when AI agents move beyond writing code and start handling the messy world of infrastructure, deployment, and operations. @funcOfJoe demoed AI agents using APIs to dynamically provision infra and explored a future where the line between code and infra just completely goes away. youtu.be/SOMEfFNPsew

Cathedral of Cascadia.
