Reasonable way to avoid locale resetting on preload?

[henrikvilhelmberglund]

I have a few buttons for selecting the user language which change the $locale store to the locale string. I had an issue where $locale would get reset to whatever initLocale was in the +layout.js when hovering over links (preload) and when changing the route.

I fixed(?) it by using the following code:

const initLocale = get(locale) ? get(locale) : "en"; // get from cookie, user session, ...

await loadTranslations(initLocale, pathname); 

which seems to work as it uses the $locale store value if it exists, otherwise "en" as a default. (Should probably use cookies/localstorage for this later)

My main question is, is there a better way to do this? I'm very new to i18n.

Hi @henrikvilhelmberglund!
Your solution is quite tricky as the locale store is shared between users on server. Recommended is to use cookies to keep user’s preferred language.. see example here.

Sorry for creating an issue instead of posting it as a discussion. 😊

I'm using the static adapter so I only really care about client behavior and it seems to work fine the way I set up. I used local storage instead of cookies for storing the preferred language though.

Saving the language as a cookie seems smart if you've got a real server so you can send the correct language pages with SSR instead of the language switching client side. I can see it flashing now in dev but it might be fast enough when built.

Could I solve it by still using the store but wrapping it in context? Like this https://kit.svelte.dev/docs/state-management#using-stores-with-context

I think I will look at the example and give it a go later! Does it still work with preloading on hover though? It seems like you removed the attribute in app.html.

I don't understand the idea of locale, then. Why have it shared between users? What does it represent? Whose locale?

I am encountering exactly the same issue. I am using the Single Load example as reference. In the project I am currently working on, during link hover (preload) the locale resets to the initial locale. What is the preferred way to handle this for a client only App?

• Is local storage acceptable? any other solutions?

@henrikvilhelmberglund just curious as to what solution you ended up using.

[henrikvilhelmberglund]

I haven't solved it for SSR because I only have a static site, but for client side I use a persisted store (localstorage) and use it with context in a layout load function like the link above. It works fine.

+layout.js
const initLocale = get(userPreferredLocale) ? get(userPreferredLocale) : "en";

stores.js
export const userPreferredLocale = persisted("preferredLocale", "en");

Thanks. I was thinking of going with a similar approach. Nice to know it works fine.
