I attended FEConf 2022 not as a participant, but as staff. After failing to secure a ticket through Naver's registration system, I volunteered as event staff and was selected.
Morning of the Event
The conference was held at Lotte World Tower. I arrived 30 minutes early to help with registration and distributed name tags to all attendees. I met Jaeyeop Han from Toss, and it was exciting to meet someone in person whose content I had been following.
Sponsor Booths
Companies like Ohouse, Banksalad, Ably, Yanolja, Toss, FastCampus, Superb AI, and Yogiyo operated booths. "Thoughtful companies provided eco bags and shopping bags," making it convenient to collect merchandise and participate in booth activities.
Valuable Sessions
Design System Beyond Form - Soyoung Lee (FLEX)
She emphasized that "design systems become bottlenecks when expectations and responsibilities are unclear." FLEX's design system evolved through three principles: functionality independent of appearance, guaranteed basic behavior, and minimal constraints.
Monorepo Management - Changyoung Oh (Toss)
A monorepo means "well-defined relationships between multiple independent projects within a single repository." Toss open-sourced their @toss/slash library.
ReScript - Miryang Jung (Greenlabs)
Advantages included eliminating style debates and readable code through pipe operators, while disadvantages included binding complexity and limited community.
PSD Parser Library - Donghyun Lee & Yehyoung Kang (Naver Webtoon)
They created an efficient library achieving "approximately 10x size reduction and 7x speed improvement." They applied WebAssembly optimization and demonstrated how CS fundamentals enhance frontend problem-solving abilities.
Import Statements - Seojin Park (Toss)
He distinguished between CommonJS and ECMAScript Modules, explaining that ESM enables static analysis while CommonJS requires file-level understanding. Node.js ESM adoption requires explicit file extensions.
Wrapping Up FEConf 2022
I was grateful for the opportunity to contribute as staff, meet outstanding developers, and participate in the tech community. I aim to eventually present at conferences like this while building my professional network.
