LisboaJS

We're a Lisbon #Javascript community born to cultivate knowledge and foster deep connection. If you're ever in town, feel free to say 👋 hi and we're happy to invite you for co-working and a bitoque or 🍺 beer after work.

I am taking the opposite bet and building a code review tool I use to look at every AI change before committing the code. argus-review.com

Join us at Casa do Impacto and work alongside other designers from our community every second Friday. Besides providing you with office space, we'll also host in-person mentoring sessions with senior designers and past speakers throughout the day. luma.com/uxqykfbj

You helped organise 16 of our events despite not even being part of the team. — Our community would probably not exist without your contribution. Do you have something nice to say about Gonçalo? Let us know your story below 👇

Thank you Gonçalo for leading by example and for doing so much for others without ever finding any need to advertise it. Last year, you used your skills to launch a platform to increase transparency in Portuguese politics.

Our Person of the Year is Gonçalo Costa. His deep and often silent contribution to our community, to the Portuguese Tech Community and to society has been unparalleled.

How might AI transform the way teams conduct user research? Watch Tiago Pombeiro talk about how the Maze AI Moderator can autonomously run and analyse interviews while keeping researchers in control of quality and insight. 👉 Watch the video on YouTube: youtu.be/AW10uQ23F8Y

We just released 𝚛𝚎𝚊𝚌𝚝-𝚋𝚎𝚜𝚝-𝚙𝚛𝚊𝚌𝚝𝚒𝚌𝚎𝚜, a repo for coding agents. React performance rules and evals to catch regressions, like accidental waterfalls and growing client bundles. How we collected them and how to install the skill ↓ vercel.com/blog/introduci…

How can we leverage AI as user researchers and product designers? Our talks from @lisbonaiweek are now all uploaded to YouTube. If you were not able to make it, now you can watch the videos and go through the slides online 👀 👉 Check our AI Playlist: youtube.com/playlist?list=…

Today we had the honour of receiving two speakers from @zurichjs. It was a cosy evening and we look forward to working together and alongside other developer communities from all corners of 🇪🇺 Europe next year. See you soon 🌞

@Ciberon @LisboaJS_ @Ciberon in @LisboaJS_

Designers work in Figma. Devs work in code. The gap between them? Gone. With @figma to @storyblok, you can turn Figma frames directly into fully structured Storyblok components, no guesswork, no re-engineering, no endless back-and-forth. Try it now: okt.to/1ob62T

In this talk, @Ciberon will offer an introduction to Effect, so it feels less like magic and more like a powerful new tool in your toolbox. 👉 Sign up here: luma.com/y8qe9gcc

While async/await made asynchronous code easier to write, it didn’t solve deeper problems like explicit error modelling, resource safety, retries, timeouts, dependency management, or composability. ​Effect is a TypeScript library designed to tackle these challenges head-on.

Modern TypeScript applications often become fragile the moment async work, failures, or side effects enter the picture. Runtime errors appear unexpectedly, race conditions creep in, and code that once felt simple becomes difficult to reason about and even harder to test.

Our first speaker, @farisaziz12, works as staff software engineer at @smallpdf, and he will talk about Caching, Payloads, and Other Dark Arts.

We still have a couple of surprises left for you in 2025. Our friends from @ZurichJS are visiting and we're hosting one last event this year. There will be azevias, fatias douradas and 2 talks about JS Under Pressure 🎅🛷❄️😱 Sign up here: luma.com/y8qe9gcc

AI can amplify what we do. Turning us into force multipliers, capable of achieving what once required entire teams. @Ugo_alves from @syntheticusers talks about AI agents and shares his experience as a product manager that has to wear many hats. youtu.be/CjUCPtCmNXE

Learn about @GitLab's playbook to craft AI experiences with real examples. From how AI fits with user needs, through key design methods, to measuring success. @PedroMScom shares what has worked well for them so far. Watch the talk on our YouTube channel: youtu.be/uIRR5N_hZnQ

If you’re new to Lisbon, there’s a place for you here. We’re a community of people who create software, and we know what it’s like to pack our bags and move somewhere new without friends. There are 7 countries represented in this picture. There’s room for more. You’re never alone
