I'm new in Angular, Node and Javascript. But I need to work on some project in this technologies. My question is like this. I would like to use library i18n-iso-countries in my project. So I executed npm install i18n-iso-countries --save. So far so good.
In my component file home.component.ts I imported it like this:
import * as countries from 'i18n-iso-countries';
and use like this to make sure library is loaded and is working:
console.log(countries.alpha2ToNumeric("PL"));
console.log(countries.numericToAlpha2(840));
console.log(countries.getName(840, "en"));
console.log(countries.getName("US", "en"));
Two first lines works as expected but last two not. I noticed that I need to register locale according to the docs. So the question is how to import locale? I need to execute
countries.registerLocale(require("i18n-iso-countries/langs/en.json"));
But the error is:
Cannot find name 'require'.
I tried also different import forms like:
import locale = require('i18n-iso-countries/lang/en.json');
import * as locale from 'i18n-iso-countries/langs/en';
But without success. Maybe I'm missing something trivial but I'm not aware of it. I read Modules chapter in typescript Handbook but it doesn't answer to my questions. Maybe You guys will help.
