The journey to a mature ecosystem

After we reflected in 2023 on the past 10 years of frontend developement, in 2024 we want to spotlight some of the established patterns and architectures that reached maturity and are becoming industry standards.

Leaving behind us the tumultuous growth of the JS ecosystem we will focus on the positive outcomes of all the years of challenging “best practices”. We want to bring on stage talks about design patterns and system architecture, but also web standards and language advancements. Along with these, we want to tackle software complexity and dealing with legacy code and legacy systems.

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 2024.

Speak at JSHeroes

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.
