如何将TypeScript导入语句转换为JS Require语句

Question

How would I convert the follow TS statement

import {TNSFontIcon, fonticon} from 'nativescript-fonticon';

Into a Javascript require statement? My thought is:

TNSFontIcon = require('nativescript-fonticon’).TNSFontIcon()

But the TS statement is importing multiple things from the file...

Ideally you can write:

var package = require('nativescript-fonticon');

var TNSFontIcon = package.TNSFontIcon;
var fonticon = package.fonticon;

// and later use it as follows
var obj = new TNSFontIcon();

This assumes that nativescript-fonticon is a commonjs package. If you're compiling the nativescript-fonticon from TypeScript you can choose from various output formats, see: https://www.typescriptlang.org/docs/handbook/compiler-options.html

Note that require isn't a standard JavaScript function and you need to polyfill with eg. requirejs .
