Alternative Caching with i18next
With i18next you can configure a cache layer to be used in the browser. It will load and cache resources from localStorage and can be used in combination with the chained backend.
import i18next from "i18next";
import ChainedBackend from "i18next-chained-backend";
import LocizeBackend from "i18next-locize-backend";
import LocalStorageBackend from "i18next-localstorage-backend";
i18next
.use(ChainedBackend)
.init({
fallbackLng: "en",
// ... your i18next config
backend: {
backends: [
LocalStorageBackend,
LocizeBackend
],
backendOptions: [{
expirationTime: 7 * 24 * 60 * 60 * 1000 // 7 days
}, {
projectId: "[PROJECTID]",
apiKey: "[APIKEY]",
version: "[VERSION]",
referenceLng: "en"
}]
}
});

With i18next you can configure a cache layer to be used on server side. It will load and cache resources from the filesystem and can be used in combination with the chained backend.
import i18next from "i18next";
import ChainedBackend from "i18next-chained-backend";
import LocizeBackend from "i18next-locize-backend";
import FsBackend from "i18next-fs-backend";
i18next
.use(ChainedBackend)
.init({
fallbackLng: "en",
// ... your i18next config
backend: {
backends: [
FsBackend,
LocizeBackend
],
backendOptions: [{
expirationTime: 7 * 24 * 60 * 60 * 1000, // 7 days
loadPath: './locales_cache/{{lng}}/{{ns}}.json',
addPath: './locales_cache/{{lng}}/{{ns}}.json' // make sure the folders "locales_cache/{{lng}}" exists
}, {
projectId: "[PROJECTID]",
apiKey: "[APIKEY]",
version: "[VERSION]",
referenceLng: "en"
}]
}
});

With i18next you can configure a cache layer to be used on react-native. It will load and cache resources from the AsyncStorage and can be used in combination with the chained backend.
import i18next from "i18next";
import ChainedBackend from "i18next-chained-backend";
import LocizeBackend from "i18next-locize-backend";
import AsyncStorageBackend from "i18next-async-storage-backend";
i18next
.use(ChainedBackend)
.init({
fallbackLng: "en",
// ... your i18next config
backend: {
backends: [
AsyncStorageBackend,
LocizeBackend
],
backendOptions: [{
expirationTime: 7 * 24 * 60 * 60 * 1000 // 7 days
}, {
projectId: "[PROJECTID]",
apiKey: "[APIKEY]",
version: "[VERSION]",
referenceLng: "en"
}]
}
});

Similar to the normal server side caching with filesystem, you can use the same approach in a Next.js app in combination with next-i18next. It will load and cache resources from the filesystem and can be used in combination with the chained backend.
The config file, will probably look similar to this, but for a more complete example have a look at this example.
// next-i18next.config.js
const ChainedBackend = require('i18next-chained-backend')
const FSBackend = require('i18next-fs-backend/cjs')
const LocizeBackend = require('i18next-locize-backend/cjs')
module.exports = {
i18n: {
defaultLocale: 'en',
locales: ['en', 'de'],
},
backend: {
backends: [
FSBackend,
LocizeBackend
],
backendOptions: [{ // make sure public/locales_cache/en and public/locales_cache/de exists
loadPath: './public/locales_cache/{{lng}}/{{ns}}.json',
addPath: './public/locales_cache/{{lng}}/{{ns}}.json',
expirationTime: 7 * 24 * 60 * 60 * 1000 // 7 days
}, {
projectId: 'd3b405cf-2532-46ae-adb8-99e88d876733',
referenceLng: 'en'
}]
},
use: [ChainedBackend],
ns: ['common', 'footer', 'second-page'], // the namespaces needs to be listed here, to make sure they got preloaded
serializeConfig: false, // because of the custom use i18next plugin
// debug: true,
}

We suggest not to use multiple backends with the i18next-chained-backend in combination with saveMissing or updateMissing, because it may happen, that the trigger for this is based on stale data.
