Examples
// Always use the same language (no per-guild configuration):
container.i18n.fetchLanguage = () => 'en-US';
// Retrieving the language from an SQL database:
container.i18n.fetchLanguage = async (context) => {
const guild = await driver.getOne('SELECT language FROM public.guild WHERE id = $1', [context.guild.id]);
return guild?.language ?? 'en-US';
};
// Retrieving the language from an ORM:
container.i18n.fetchLanguage = async (context) => {
const guild = await driver.getRepository(GuildEntity).findOne({ id: context.guild.id });
return guild?.language ?? 'en-US';
};
// Retrieving the language on a per channel basis, e.g. per user or guild channel (ORM example but same principles apply):
container.i18n.fetchLanguage = async (context) => {
const channel = await driver.getRepository(ChannelEntity).findOne({ id: context.channel.id });
return channel?.language ?? 'en-US';
