Most of Case

• en_US.json

{
    "name": "Victor"
}

• ko_KR.json

{
    "name": "빅터"
}

• index.js

const path = require('path');
const I18n = require('op-i18n');

// Note that '_' is used instead of '-' for key in options below.
// eg. ko-KR:{} (X), ko_KR:{} (O)
const options =
{
  locales:
  {
      ko_KR:
      {
        name: '한국어',
        iso: 'ko-KR',
        file: 'ko_KR.json'
      },
      en_US:
      {
        name: 'English',
        iso: 'en-US',
        file: 'en_US.json'
      }
  },
  directory: path.resolve(__dirname, 'locales/'),
  defaultLocale: 'en_US',
}

const i18n = new I18n(options);

// Change locale to Korean
i18n.updateDefaultLocale("ko_KR");
console.log(i18n.$t());
// output: { name: '빅터' }
console.log(i18n.$t("name"));
// output: 빅터
console.log(i18n.$t("name", "en_US"));
// output: Victor

Options

Requires locales, directory, defaultLocale in options. Note that _ is used instead of - for key in options.

const path = require('path');
const I18n = require('op-i18n');

// Note that '_' is used instead of '-' for key in options below.
// eg. ko-KR:{} (X), ko_KR:{} (O)
const options =
{
  locales:
  {
      ko_KR:
      {
        name: '한국어',
        iso: 'ko-KR',
        file: 'ko_KR.json'
      },
      en_US:
      {
        name: 'English',
        iso: 'en-US',
        file: 'en_US.json'
      }
  },
  directory: path.resolve(__dirname, 'locales/'),
  defaultLocale: 'en_US',
}

const i18n = new I18n(options);

Advanced $t()

Regular

You can use . notation just like how you get value out of js object:

• ko_KR.json

{
    "name":
    {
        "first": "빅터"
        "last": "박"
    }
}

• en_US.json

{
    "name":
    {
        "first": "Victor"
        "last": "Park"
    }
}

• index.js

const path = require('path');
const I18n = require('op-i18n');

// Note that '_' is used instead of '-' for key in options below.
// eg. ko-KR:{} (X), ko_KR:{} (O)
const options =
{
  locales:
  {
      ko_KR:
      {
        name: '한국어',
        iso: 'ko-KR',
        file: 'ko_KR.json'
      },
      en_US:
      {
        name: 'English',
        iso: 'en-US',
        file: 'en_US.json'
      }
  },
  directory: path.resolve(__dirname, 'locales/'),
  defaultLocale: 'en_US',
}

const i18n = new I18n(options);

console.log(i18n.$t("name.first"));
//output: Victor

For getting value from specified locale:

console.log(i18n.$t("name.first", "ko_KR"));
//output: 빅터

You can get whole js object with empty key "".

console.log(i18n.$t(""));
//output: { name: { first: "Victor", last: "Park" } }
console.log(i18n.$t("", "ko_KR"));
//output: { name: { first: "빅터", last: "박" } }

Using Object

You can use object to get translation as well. { locale: "", key: "" }.

console.log(i18n.$t( { key:"name.first" } ));
//output: Victor
console.log(i18n.$t( { locale: "ko_KR", key:"name.first" } ));
//output: 빅터
