719-746: Complete internationalization for the open source section.This section contains hardcoded English text including "We build open source games and tools together" and related content that should be internationalized.
Add translation keys for this section to ensure consistent multilingual support across the entire page.
857-882: Complete internationalization for the IRL community section.The "Find your IRL community" section and its subtitle contain hardcoded English text that should use translation keys for consistency with the rest of the internationalized content.

🧹 Nitpick comments (9)
translations.json (1)
1-10: Prefer per-locale resource files over a singletranslations.jsoni18next (and
next-i18next) look for translation namespaces insidepublic/locales/<lng>/<ns>.json.
Keeping an additional root-leveltranslations.jsonwith duplicate keys:
- introduces another source of truth that can easily diverge from the canonical
public/locales/*files,- is not loaded automatically by the library, so the data is effectively unused unless extra plumbing is added.
Consider deleting this file and consolidating the strings under the existing
public/locales/{en,tr}/common.json(or another namespace) to avoid drift.public/locales/en/common.json (1)
1-4: Minor: drop punctuation to keep keys identical across localesKey
"welcome"carries"Welcome!"here but"Welcome"in other files.
Uniform values (and punctuation) simplify copy-editing and avoid accidental fallback mismatches.No functional impact; treat as style guidance.
public/locales/tr/common.json (1)
1-4: Align punctuation with English counterpartSame note as above – consider removing the exclamation mark or adding it to both locales for consistency.
public/locales/en/index.json (1)
1-9: Consider consolidating translation files for better maintainability.The JSON structure and content are well-organized. However, having separate files like
index.json,translation.json, andcommon.jsonmight lead to confusion about where to place new translations. Consider consolidating into a single main translation file or establish clear guidelines for file organization.components/languageSwitcher/LanguageSwitcher.js (2)
20-41: Enhance accessibility and add responsive considerations.Consider adding accessibility attributes and responsive behavior for mobile devices.
<Button key={lang.code} onClick={() => changeLanguage(lang.code)} variant={i18n.language === lang.code ? 'primary' : 'outline'} + aria-label={`Switch to ${lang.name}`} + aria-pressed={i18n.language === lang.code} sx={{ fontSize: 1, py: 1, px: 2, display: 'flex', alignItems: 'center', gap: 1, cursor: 'pointer', opacity: i18n.language === lang.code ? 1 : 0.7, + '@media (max-width: 48em)': { + fontSize: 0, + px: 1 + }, '&:hover': { opacity: 1 } }} >
11-14: Consider making language configuration external.Hardcoding the language list limits flexibility. Consider moving this to a configuration file or making it configurable via props.
- const languages = [ - { code: 'en', name: 'English', flag: '🇺🇸' }, - { code: 'tr', name: 'Türkçe', flag: '🇹🇷' } - ] + const languages = [ + { code: 'en', name: t('english'), flag: '🇺🇸' }, + { code: 'tr', name: t('turkish'), flag: '🇹🇷' } + ]public/locales/tr/translation.json (1)
89-93: Consider consistency in terminology translation.Ensure consistent translation of technical terms throughout the application. For example, "Hack Kulüpleri" for "Hack Clubs" should be used consistently across all translation files.
pages/index.js (1)
47-48: Verify if the i18n import is necessary.The
i18nimport on line 47 doesn't appear to be used directly in the component. Only theuseTranslationhook is utilized. Consider removing the unused import unless it's required for initialization.-import i18n from '../lib/i18n' import { useTranslation } from 'react-i18next'lib/i18n.js (1)
1-56: Well-configured i18n setup with a potential optimization opportunity.The i18n configuration is comprehensive and follows best practices:
- Proper plugin integration for language detection and React
- Appropriate fallback language and debug settings
- Comprehensive language detection strategy
- Correct React integration options
However, consider lazy-loading translation files for better performance:
For better bundle optimization, consider using dynamic imports for translation files:
-// Import translation files -import enTranslations from '../public/locales/en/translation.json' -import trTranslations from '../public/locales/tr/translation.json' i18n .use(LanguageDetector) .use(initReactI18next) .init({ debug: process.env.NODE_ENV === 'development', fallbackLng: 'en', interpolation: { escapeValue: false, }, - resources: { - en: { - translation: enTranslations - }, - tr: { - translation: trTranslations - } - }, + // Load resources dynamically + resources: {}, + + // Backend configuration for loading translations + backend: { + loadPath: '/locales/{{lng}}/{{ns}}.json', + },This approach would require adding
i18next-http-backendplugin but would improve initial bundle size.

🛠️ Refactor suggestion
Make the "Language:" label translatable.
The label is hardcoded in English, which defeats the purpose of internationalization. It should use a translation key.
- <Text sx={{ fontSize: 1, fontWeight: 'bold' }}>Language:</Text>
+ <Text sx={{ fontSize: 1, fontWeight: 'bold' }}>{t('language')}:</Text>And add the translation key to your locale files:
{
"language": "Language"
}🤖 Prompt for AI Agents
In components/languageSwitcher/LanguageSwitcher.js at line 18, the "Language:"
label is hardcoded in English, which breaks internationalization. Replace the
hardcoded text with a translation function call using a key like "language".
Then, add the "language" key with the value "Language" to your locale JSON files
to support translations.

🧩 Analysis chain
Verify responsive behavior of the language switcher.
The LanguageSwitcher is well-positioned in the navigation. However, ensure it behaves appropriately on mobile devices where navigation collapses.
🏁 Script executed:
#!/bin/bash
# Description: Check if LanguageSwitcher has responsive considerations
# Expected: Component should handle mobile layouts appropriately
# Look for responsive styles in the LanguageSwitcher component
rg -A 10 -B 5 "@media|sx.*display|mobile" components/languageSwitcher/LanguageSwitcher.jsLength of output: 91
We didn’t locate any responsive rules with the previous grep. Let’s first find the exact LanguageSwitcher file and then inspect it for breakpoints or media queries:
🏁 Script executed:
#!/bin/bash
# 1. Locate the LanguageSwitcher component file
rg -l "export.*LanguageSwitcher" -g "*.js" -g "*.jsx" -g "*.ts" -g "*.tsx"
# 2. If found, inspect for responsive patterns
FILE=$(rg -l "export.*LanguageSwitcher" -g "*.js" -g "*.jsx" -g "*.ts" -g "*.tsx" | head -n1)
if [ -n "$FILE" ]; then
echo "🔍 Inspecting $FILE for responsive styling…"
echo "--- @media queries ---"
rg -n -C 3 "@media" "$FILE"
echo "--- sx props ---"

echo "--- useMediaQuery hook ---"
rg -n -C 3 "useMediaQuery" "$FILE"
else
echo "❌ LanguageSwitcher component file not found"
fiLength of output: 1335
Ensure LanguageSwitcher adapts to mobile layouts
The LanguageSwitcher currently uses a static <Flex> layout without any breakpoints, media queries, or conditional rendering. On narrow viewports it may overflow or clash with the collapsed nav. Please add responsive handling so it either hides or reflows appropriately.

- sx={{ gap: 2, alignItems: 'center' }}
- sx={{

🤖 Prompt for AI Agents
In components/nav.js at line 231, the LanguageSwitcher component lacks
responsive design and may overflow on narrow viewports. To fix this, update the
LanguageSwitcher usage by wrapping it in a conditional display component like
<Hide below="md"> or <Show above="sm"> to hide it on small screens, or modify
its sx props in components/languageSwitcher/LanguageSwitcher.js (lines ~16–27)
to use responsive arrays for layout values. Alternatively, implement
useMediaQuery inside LanguageSwitcher to render different layouts based on
screen size.
