Migration Guide

From v2 To v3

Version 3 uses ISO 639-1 language codes for Japanese, Korean, and Chinese.

Update calls like this:

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

setLanguage('ja');
setLanguage('ko');
setLanguage('zh');

translateErrorCode() without a lang argument now uses the language set by setLanguage() instead of always trying browser detection.

From v1 To v2

Version 2 added service-specific translation maps. translateErrorCode() now requires a service argument.

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

// v1
translateErrorCode('invalid_credentials');

// v2 and newer
translateErrorCode('invalid_credentials', 'auth');

Choose the service from the Supabase API that produced the error.
