The experience of using Node.JS with TypeScript, ts-node, and ESM is horrible.

There are countless guides of how to integrate them, but none of them seem to work.

Here's what worked for me.

Just add the following files and run npm run dev. You'll be good to go!

`package.json`

learn blockchain concepts
learn ethereum
learn how to use metamask
learn how to use hardhat (https://hardhat.org/)
learn how to deploy and interact with a smart contract
learn common smart contract standards like ERC20 (token), ERC721 (nft), ERC1155 (opensea)
learn ipfs
learn how to read blockchain explorers like https://etherscan.io/
learn how to use web3 and etherjs
learn solidity

How to use async/await without try/catch block

We can use something like this:

async function resolveToNumber () {
  const promise = Promise.resolve(1)
  const [error, result] = await to(promise)
  console.log(error, result) // [null, 1] -> Here we have the result, and error will be null
}

Create Reducer

Less boilerplate when create a new reducer on Redux

Method:

'use strict'

const createReducer = (initialState, actionHandlers) =&gt; {

	{
	"name": "rescript-vanilla",
	"sources": [
	{
	"dir": "src",
	"subdirs": true
	}
	],
	"package-specs": [
	{

	import { useEffect } from 'react'
	import hotkeys from 'hotkeys-js'

	export const useHotkeys = (key: string, cb: () => any, inputs?: any[]) => {
	useEffect(() => {
	hotkeys(key, cb)
	return () => hotkeys.unbind(key)
	}, inputs)
	}

	#!/bin/bash


	# This is in progress I tested it only on macOS 10.13.6
	# outuput e.g:
	# PID (319) Spotify -> :57621
	function ports {
	PORTS=$(lsof -iTCP -sTCP:LISTEN -nP)
	echo "$PORTS" \| awk 'match($9, /[\]\|\]+:(.)$/) { print " PID ("$2") "$1" -> "substr($9, RSTART+1, RLENGTH-1) }'
	}
