Can use different files for the same language?

[Degeoksz]

Right now i'm using express and i have two files in my "locales" folder.

• es.json
• en.json

is there a possibility to use different files for the same language (to have a more organized files). Example:

• es-some-type-of-content.json
• es-other-type-of-content.json

This is the configuration used in the app.js file

i18n.configure({
  locales: ["es", "en],
  directory: __dirname + "/locales",
  defaultLocale: "es",
  cookie: "locale",
  updateFiles: false
});

Any update on this?

loading from multiple sources is not (yet) supported

I had the same requirement.
Luckily i18n provides us with the getCatalog function.
So this is possible:

   function addLocaleFile(locale, file) {
        // get i18n catalog instance
        let catalog = i18n.getCatalog();
        if (!catalog) {
            return;
        }

        // load file
        let localeFile = fs.readFileSync(file);
        let newLocale = JSON.parse(localeFile);

        // merge existing with new locales
        catalog[locale] = catalog[locale] ? {...catalog[locale], ...newLocale } : newLocale;
    };

Make sure you call i18n.configure with your base locales first.
After that you can call the upper function as often as you need.

addLocaleFile('es', './locales/es-some-type-of-content.json');
addLocaleFile('es', './locales/es-other-type-of-content.json');

So I used this to merge a hierarchy of locales
/locales/de.json
/locales/manage/de.json
/locales/manage/users/de.json

besides the solution mentioned by @Khaos66 earlier you might take a look at https://github.com/mashpie/i18n-node#some-words-on-staticcatalog-option

or

to implement your own custom storage with

well it depends on your needs, but given your namespaces I'd consider the following as starting point:

files setup like so:

├── index.js
└── locales
    ├── common-en.json
    └── invoice-en.json

// common-en.json

{
  "greeting": "Hello"
}

// invoice-en.json

{
  "balance": "Balance"
}

// index.js

const fs = require('fs')
const i18n = require('i18n')

/**
 * very simple file loader treating each file as namespace
 */
const fileLoader = (locale, files) => {
  const translations = {}
  files.forEach((file) => {
    try {
      translations[file] = JSON.parse(fs.readFileSync(`./locales/${file}-${locale}.json`))
    } catch (err) {
      console.error(err);
    }
    
  })
  return translations
}

/**
 * Load translations from files
 * with each file representing a namespace
 */
i18n.configure({
  defaultLocale: 'en',
  objectNotation: true,
  updateFiles: false,
  staticCatalog: {
    en: fileLoader('en', ['common', 'invoice'])
  }
})

/**
 * debug loaded catalog
 */
console.log(i18n.getCatalog('en')) // --> { common: { greeting: 'Hello' }, invoice: { balance: 'Balance' } }

console.log(i18n.__('common.greeting')) // --> Hello
console.log(i18n.__('invoice.balance')) // --> Balance
