SvelteKit i18n starter
This is a starter like we use here at Reepolee for all our SvelteKit projects. We're using the svelte-i18n library and i18n-ally VSCode extension. Tailwind is set up as a CSS helper.
Setup
After cloning, copy .env.example to .env and run the following from the project folder as you would for any SvelteKit project:
pnpm install
pnpm run dev
Point your browser to http://localhost:5173 and enjoy your multi language app.
How it works
Optional parameter [[lang=lang]] is set as the top route. If it's present in the URL, hooks will set a cookie for it as selected language and forward it as locals.lang. If lang param is not present, locals.lang will be set from either cookie, request header or default value.
That way the app is always aware of what locale should be set and rendered.
Translations
Translations reside in /src/translations folder. A subfolder is created for every supported language, for example en, de and sl. Subfolder contains JSON files with translations. Nesting is possible and you access a translated text by its key. For example in a file called home.json with the following content:
{
"url": "/sl",
"caption": "Domov",
"menu_label": "Domov",
"title": "Reepolee Starter"
}
you can display Reepolee Starter by accessing the translated string with {$_('home.title')}.
Languages can be sorted by prefixing the code with a number or characters. For example, folder names could be 1-sl,2-en,3-de. Hyphen is a simple separator to allow for alphabetical sort and anything before it is discarded.
Theming
Tailwind classes light and dark are used on <HTML> tag to switch between themes. Class is set from cookie, defaults to prefers-color-scheme. Helper component <ThemeSwitch> is available within navigation. Theme colors are defined in src/theme.postcss.
