Using TypeScript Node.js with native ESM

This reference guide shows how to configure a TypeScript Node.js project to work and compile to to native ESM.

Rationale

CommonJS module system was introduced by the Node.js developers due to the lack of the notion of "modules" in the original JavaScript (ECMAScript) language specification at that time. However, nowadays, ECMAScript has a standard module system called ESM — ECMAScript Modules, which is a part of the accepted standard. This way CommonJS could be considered vendor-specific and obsolete/legacy. Hopefully, TypeScript ecosystem now supports the "new" standard.

So the key benefits are:

const provider = new HttpProvider('https://toncenter.com/api/v2/jsonRPC', {
    apiKey: '…',
});

const wallet = new WalletV3ContractR2(provider, {
    publicKey,
});

(async () => {

import TonWeb from 'tonweb';


(async () => {

    const tonweb = new TonWeb(
        new TonWeb.HttpProvider()
    );

import TonWeb from 'tonweb';

import {
  BatchLoadedHandler,
  getAddressTransactions,
  HttpErrorHandler,
  TransactionDiscoveredHandler,

} from './address-transactions';

/**
 * This smart directive accepts boolean value as an input and focuses the
 * element based on the evaluated boolean expression.
 *
 * Also, the directive could be applied to the input/button/select/a elements
 * directly or to any parent element as well. It will search the DOM for the first
 * suitable element to focus automatically.
