Event description
JavaScript turned thirty this year and it shows no signs of slowing down. TypeScript has become the default. Runtimes beyond Node are gaining serious traction. Bundlers have gone from necessary evils to legitimate competitive advantages. The TypeScript & JavaScript Conference is a one-day, single-track event to make sense of where the ecosystem is headed and what that means for the software you ship.
What to expect
Seven talks from engineers and open-source maintainers who are actively shaping the ecosystem. The event is deliberately small (200 seats) so that every speaker is accessible and every conversation has a chance to go somewhere interesting. The after-party is included in the ticket and typically runs three hours longer than planned.
Programme highlights
- "TypeScript 5.5 and the path to 6.0" -
noUncheckedIndexedAccess, inferred type predicates, and what the team is actually working on - "Bun in production: an honest retrospective" - one year after migrating a medium-size Node.js service; what worked and what did not
- "Vite 6 internals" - the new module runner, environment API, and what it enables for framework authors
- "Type-safe SQL without the ORM overhead" -
kysely,drizzle, and the case for query builders in TypeScript - "React 19's concurrency model explained" -
useTransition,Suspense, anduse()in a unified mental model - "Full-stack TypeScript with tRPC and Next.js" - end-to-end type safety without a GraphQL schema

--profflag in 60 minutes
Who should attend
Frontend and backend engineers who work with JavaScript or TypeScript professionally. Framework authors and OSS contributors are especially welcome.
