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:

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

Use ESM yourself. (preferred)
Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
Stay on the existing version of the package until you can move to ESM.

set http or socks proxy environment variables

# set http proxy
export http_proxy=http://PROXYHOST:PROXYPORT

# set http proxy with user and password
export http_proxy=http://USERNAME:PASSWORD@PROXYHOST:PROXYPORT

# set http proxy with user and password (with special characters)

How to mount a VirtualBox shared folder when the Guest OS boots

Problem

While using VirtualBox's Guest Additions to mount shared folders provides a seamless way to mount shared folders, there are also disadvantages.

Shared folders will always mount in /media/sf_(share name) unless specified using through vbox drivers in the guest OS
Mounting does not happen at boot-time. Applications that require paths at boot will not be able to access the shared folder even after it is mounted - such as Docker.

Solution

Instead of relying on Guest Additions, if you have sudo permissions, shared folders can be mounted at boot-time using fstab. Using this approach allows

Installing Arch Linux with Full Disk Encryption

If you're aiming for a seamless Arch Linux installation in UEFI mode, follow along as this guide will walk you through the process step by step. We'll be using LUKS (Linux Unified Key Setup) and LVM (Logical Volume Manager) partitions on LUKS to achieve full disk encryption.

Note: I have updated this doc for UEFI mode. For those with BIOS/MBR systems, you can refer to the previous version, but keep in mind that it might be outdated and no longer accurate.

If you're only interested in installing Linux and not setting up dual boot with Windows, feel free to skip the Windows-related sections.
