JSHeroes 2027 is a non-profit, community-organised JavaScript conference held in Cluj-Napoca, Romania, for developers who work across the modern web platform. The event is built around a single-track programme, which means every attendee sees the same talks and shares the same conversations, and its focus sits squarely on JavaScript, front-end engineering and the wider ecosystem of tools and frameworks that power today's browsers and servers. The 2027 edition is scheduled for 27–28 May in Cluj-Napoca, one of Romania's most active technology hubs and a university city with a strong software industry. As a two-day in-person JavaScript conference in Eastern Europe, JSHeroes draws practitioners from across the region and beyond, and its volunteer-driven organisation keeps the emphasis on content quality rather than commercial exhibition. Attendees can expect technical talks on web development practice, time between sessions for networking with speakers and peers, and the informal hallway conversations that a single-track format encourages. For front-end and full-stack engineers in Central and Eastern Europe, JSHeroes remains a focused, community-first gathering that strengthens the regional JavaScript scene.
