Server translations

Server-side translations are managed by the same library as the client, i18next.
The translation files reside in the /translations directory, following the same convention as the client (translations/{{lng}}/{{ns}}.json), where the namespace is server.json. So for the Spanish translations we have translations/es/server.json.
Loading of translations is managed by i18next-fs-backend which loads the translations directly from the file system (unlike HTTP requests like the client), at the path mentioned previously (relative to package.json).

How to translate a string

Unlike the client which uses a dedicated client service, the i18next library on the server is used directly, as such:

import { t } from "i18next";

const translatedString = t("message.id");

Avoid translating server-side logs, as those are supposed to be for debugging and as such there is no benefit in translating them.
Translate any user-facing message that comes from the server, such as error messages shown in the Electron application, or information such as keyboard shortcuts, note titles, etc.
