See you in 2023!

We had a blast in 2022 and we were super happy to see you all in person again after 3 years. So based on this experience, we’re coming back in 2023 with a two-day event, a format that used to be our way to go in a pre-pandemic world.

Tickets are available on our ti.to page. If PayPal is not your preferred payment method, you can also pay by invoice. For more information drop us a line at welcome@jsheroes.io.

Looking forward to seeing you all back in Cluj, on the 18th and 19th of May 2023!

    35 years of experience have not dulled the fascination Gil Tayar has with software development. His passion is distributed systems and figuring out how to scale development to big teams. Extreme modularity and testing are the main tools in his toolbelt, using them to combat the code spaghetti monster at companies like Wix, Applitools, and at his current job as software engineer at Microsoft.

    In his private life, he is a dad to two lovely kids, an avid reader of Science Fiction (he counts Samuel Delany, Robert Silverberg, and Robert Heinlein as favorites) and a passionate film buff. (Stanley Kubrick, Lars Von Trier, David Cronenberg, anybody?)

    Unfortunately for him, he hasn’t answered the big question of his life—what’s better, static or dynamic languages? But he’s working on it.

10 years of pushing the boundaries

This year we want to shift our attention to the decade of progress in the world of web development. Back in 2013, we went through a period of rethinking practices as frontend development took off and became one of the most crucial disciplines in tech. Frameworks like: React, Angular or Vue, and their ecosystems now enter into their second decade of existence, while web capabilities and standards are increasingly more potent and versatile.

So in 2023, let’s celebrate the past 10 years, reflecting on the evolution of our tools and patterns, with the good and the bad that comes with this rapid evolution.

At JSHeroes, we always ventured outside the pure language ecosystem, so expect to see a variety of talks covering the entire landscape of web development and JavaScript as a universal programming language.

But of course, we will not neglect the human side of things, in our effort to paint a full picture for the development community in 2023.

An open-source community event

JSHeroes is a non-profit community-organized conference, held every year in Cluj, Romania. Our goal is to bring together JS and Web/Frontend development enthusiasts from all over the world for a two day event with: great talks, amazing networking and tons of fun. You bring your ideas and desire to learn, we provide the relaxed atmosphere and the good vibes.

We believe that the community and the open-source models are well suited for our core values: learning, teaching and knowledge sharing. Our mission is to inspire other communities with the concept of open-source events.

We’re publishing all data about this conference, in full transparency. We are also available at any time for inquires and we’re really looking forward to sharing our knowledge about organizing international events. This way, whenever a community wants to start something similar, they can build on our knowledge.
