Why I use node, deno, bun, qjs, tjs at the same time.

Winds up being a (not the) rather comprehensive JavaScript toolbox. The idea being for the modern JavaScript programmer can use all of the tools available for a given requirement, task or job, without preference for any. No external bundlers or compilers are needed. No frameworks are needed. I can use qjs or tjs for systems with minimal RAM and disk space; and when I want to use Web API's deno makes an effort to provide those interfaces. In some cases I can run the exact same code in bun, deno, and node, which provides a means to perform 1:1 testing as to performance.

There's probably a few things I am unintentionally omitting below. These are just a brief synposis. I'll update accordingly.

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:

1. 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.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.

const crypto = require("crypto")

// The `generateKeyPairSync` method accepts two arguments:
// 1. The type ok keys we want, which in this case is "rsa"
// 2. An object with the properties of the key
const { publicKey, privateKey } = crypto.generateKeyPairSync("rsa", {
	// The standard secure default length for RSA keys is 2048 bits
	modulusLength: 2048,

Demystifying Docker Volumes for Mac and PC Users

1. Docker runs on a Linux kernel

Docker can be confusing to PC and Windows users because many tutorials on that topic assume you're using a Linux machine.

As a Linux user, you learn that Volumes are stored in a part of the host filesystem managed by Docker, and that is /var/lib/docker/volumes. When you're running Docker on a Windows or Mac OS machine, you will read the same documentation and instructions but feel frustrated as that path don't exist on your system. This simple note is my answer to that.

When you use Docker on a Windows PC, you're typically doing one of these two things:

• Run Linux containers in a full Linux VM (what Docker typically does today)

Node.js Deployment

Steps to deploy a Node.js app to DigitalOcean using PM2, NGINX as a reverse proxy and an SSL from LetsEncrypt

1. Sign up for Digital Ocean

If you use the referal link below, you get $10 free (1 or 2 months) https://m.do.co/c/5424d440c63a

2. Create a droplet and log in via ssh

I will be using the root user, but would suggest creating a new user
