Quick Start

Translate a Supabase Auth error code:

import { translateErrorCode } from 'supabase-error-translator-js';

const message = translateErrorCode('invalid_credentials', 'auth', 'de');

console.log(message);

Set a process-wide or browser-session default language:

import { setLanguage, translateErrorCode } from 'supabase-error-translator-js';

setLanguage('es');

const message = translateErrorCode('email_not_confirmed', 'auth');

Use browser language detection:

import { setLanguage } from 'supabase-error-translator-js';

setLanguage('auto');

For server-side rendering or request handlers, prefer passing the language to translateErrorCode() for each call:

import { translateErrorCode, type SupportedLanguage } from 'supabase-error-translator-js';

export function translateSupabaseError(code: string | undefined, userLanguage: SupportedLanguage) {
  return translateErrorCode(code, 'auth', userLanguage);
}
