Lokalise Reference Architecture
Overview
A production-ready architecture for integrating Lokalise into web applications. Covers the end-to-end translation flow from source code through CI/CD and Lokalise to deployed translations, recommended project structure for i18n, file organization conventions, multi-app translation sharing, and the tradeoffs between OTA (over-the-air) and build-time translation loading.
Follow these conventions for translation file organization:
Flat keys (recommended for most projects — simpler grep, no nesting ambiguity):
{"homepage.hero.title":"Welcome to MyApp","homepage.hero.subtitle":"The best app ever","settings.profile.name_label":"Full Name","errors.not_found":"Page not found"}
Nested keys work better for large projects with clear module boundaries, where each top-level key maps to a feature area. Both formats are supported by Lokalise and i18next.
Key naming conventions:
Use dot notation: module.section.element
Use snake_case for key segments: user_profile, not userProfile
Prefix by feature area: checkout.payment.card_label
Use consistent suffixes: _title, _label, _button, _error, _placeholder
Keep keys under 100 characters (Lokalise hard limit is 1024 chars per key name)
File naming:
One file per locale: en.json, de.json, fr.json
For large apps, split by namespace: common.json, auth.json, dashboard.json
Namespace files go in subdirectories: locales/en/common.json, locales/en/auth.json
Step 6: Multi-App Translation Sharing
When multiple applications share translations (e.g., web app + mobile app + marketing site):
Alternative: Separate projects with key linking. Lokalise does not natively share keys across projects, so tag-based filtering within a single project is the recommended approach for shared translations.
Step 7: OTA vs Build-Time Translation Loading
Choose the right delivery strategy based on your requirements:
Factor
Build-Time
OTA
Latency
Zero (bundled)
Network request on first load
Update speed
Requires deployment
Instant (CDN cache)
Offline support
Full
Needs initial fetch + local cache
Bundle size
Increases with locales
Minimal (loaded on demand)
Reliability
No external dependency
Depends on Lokalise CDN
Best for
Server-rendered apps, SPAs with CI/CD
Mobile apps, rapid copy changes
Build-time implementation (recommended for most web apps):
// src/i18n/loader-buildtime.ts// Translations are imported statically — bundled at build timeimport en from'../locales/en.json';
import de from'../locales/de.json';
import fr from'../locales/fr.json';
consttranslations: Record<string, Record<string, unknown>> = { en, de, fr };
exportfunctionloadTranslation(locale: string): Record<string, unknown> {
return translations[locale] ?? translations['en'];
}
OTA implementation (for instant translation updates without redeployment):
// src/i18n/loader-ota.tsimport i18next from'i18next';
importLocizeBackendfrom'i18next-locize-backend'; // or i18next-http-backend// Lokalise OTA requires the @lokalise/i18next-ota-plugin or a custom backend// pointing at the Lokalise OTA endpoint.
i18next
.use(LocizeBackend)
.init({
backend: {
// Lokalise OTA SDK endpoint// See:loadPath: `https://ota.lokalise.com/v3/public/${process.env.LOKALISE_OTA_TOKEN}/{{lng}}/{{ns}}`,
},
fallbackLng: 'en',
ns: ['translation'],
defaultNS: 'translation',
});
Hybrid approach (recommended for production):
// src/i18n/loader-hybrid.tsimport bundledEn from'../locales/en.json';
/**
* Load bundled translations immediately, then attempt OTA update.
* User sees bundled content instantly; OTA updates appear on next render.
*/exportasyncfunctionloadWithOtaFallback(locale: string): Promise<Record<string, unknown>> {
// 1. Start with bundled translations (instant)const bundled = awaitimport(`../locales/${locale}.json`)
.then(m => m.default)
.catch(() => bundledEn);
// 2. Attempt OTA fetch in background (non-blocking)fetchOtaTranslations(locale)
.then(ota => {
if (ota) {
// Merge OTA translations over bundled (OTA wins on conflicts)Object.assign(i18next.store.data[locale].translation, ota);
i18next.emit('loaded');
}
})
.catch(() => { /* OTA failed, bundled translations are sufficient */ });
return bundled;
}
asyncfunctionfetchOtaTranslations(locale: string): Promise<Record<string, unknown> | null> {
const otaToken = process.env.LOKALISE_OTA_TOKEN;
if (!otaToken) returnnull;
const response = awaitfetch(`https://ota.lokalise.com/v3/public/${otaToken}/${locale}/translation`, {
signal: AbortSignal.timeout(5000),
});
if (!response.ok) returnnull;
return response.json();
}
Step 8: TypeScript Type Safety
Generate types from your source locale to get compile-time checks on translation keys:
Enterprise adds: client.ts (Step 4), loader-hybrid.ts (Step 7), fallback.ts, middleware.ts, types.ts (Step 8), locales-fallback/ directory, validate-translations.ts, generate-types.ts, and CI workflows. See the full tree in Step 2.
