congrats man!
The hard work really shows, you look real svelte now (Pun intended)
will you be hiking up to the Everest base camp next year?

Next up, we have @wattanx.dev with a delightful talk on designing "pleasant animations".
A very practical guide with tons of tips and tricks I can't wait to apply at work starting tomorrow!

having never built a design system myself, this talk on creating & maintaining design system documentation by @takanorip.com was really eye opening!
I wonder if a storybook plugin to generate versioned documentation for non-ui parts of design systems could be useful..

Sadly I don't know of any cross language communities.. although I'm sure there are plenty!
The svelte japan discord is open for anyone though, even if you're just svelte-curious!

@danabra.mov I'll ask at work tomorrow if we have any open roles (I'm at LINEヤフー, but most of our roles seem to require business Japanese)
are you exclusively looking for frontend gigs or would you also be open for BE / native positions? I believe we have a few English-only teams there

lovely pic, that jacket is SO you!!!
November 10, 2025 at 2:53 PM
and newly connect with so many cool folks!
Non-exhaustive list of folks I'm lucky to have met at VueFes:
@danielroe.dev sorry 'bout your umbrella, @rebaar.com your powerbank saved me! @danabra.mov enjoy kyoto! @hiogawa.bsky.social thanks for vitest!

and yes, that's me posing as a vue-themed drink 😅

@kazupon.dev & @vuefes.bsky.social staff team, y'all did it again!
What a beautiful event - filled to the brim with talks from the leading edge of web development and lovely people ❤️
Grateful for getting to re-connect (@pilcrowonpaper.com, @hirok.io, @sxzz.dev, @dominikg.dev & the Svelte Japan crew)

Last but not least, we had @antfu.me test the capacities of the venue by drawing a huge crowd for his first ever conference talk in Japanese!
His presentation envisioned a future where Vite DevTools make it trivial to introspect your applications - powered by an ecosystem built on DevTools Kit

Tucked away in a small room on the lower floor I listened to a hidden gem of this conference: my friend Yogo's talk on the web audio API
being formally trained as a composer at Tokyo Geidai, he showcased the ins-and-outs of using filter nodes to manipulate sound on the web - fantastic talk!

multi-track conferences sadly come with some overlap between talks, so I had to sneak out from the panel to catch the next talk on how rust-based tooling runs in JS environments by my friend @ssssota.bsky.social!
A very timely talk lifting the mystery behind all those rust tools showcased at vuefes!
