2026 Edition

Four cities. Two continents. One global JavaScript community.

In 2026, CityJS continues its journey across the world with events in London, New Delhi, Singapore and Athens — bringing together developers, international speakers, technology leaders and partners from across the JavaScript ecosystem.

CityJS around the world

London, United Kingdom

Each CityJS event is built around what matters most to our community: high-quality technical content, real-world knowledge, new ideas and meaningful connections.

For attendees, it’s an opportunity to learn from experienced practitioners, discover what’s next in JavaScript and web technologies, and meet developers from diverse communities.

For sponsors and partners, CityJS offers something equally valuable: the opportunity to meet technical audiences face-to-face, demonstrate your technology, build developer relationships and become part of an established international community.
