The official website for GopherCon Japan.

• built with Astro
• internationalized with Intlayer (English default at /, Japanese at /ja)
• deployed to Cloudflare Workers as static assets.

Stack

bun (pinned by mise) · Astro + TypeScript · Intlayer · Storybook

Getting started

mise install              # install pinned runtimes
eval "$(mise activate)"   # enable mise shims (add to your shell rc to persist)
bun install
bun run dev               # http://localhost:4321 (en at /, ja at /ja)

The commands below assume the mise shims are active. Without shims, prefix them with mise exec -- (e.g. mise exec -- bun run dev).

Commands

Command	Description

i18n (Intlayer)

• Routing: intlayer.config.ts → routing.mode: "prefix-no-default" (en at /, ja at /ja).
• Dictionaries are embedded in components as locale-keyed objects, resolved with getDictionary. requiredLocales: [en, ja] makes TypeScript complain about missing translations.
• LocaleRedirector detects the browser locale (unsupported → defaultLocale) and redirects; LocaleSwitcher renders the language links and persists the choice.

Deployment

Cloudflare Workers (Static Assets) with a pull-based build — wrangler.jsonc points assets.directory at ./dist. To preview on the Workers runtime:

bun run preview:cf
