Using Node's built-in watch mode.

Using Node's built-in support for environment variable files (.env files).

How to use Node's built in test runner and assertion library.

Install the VS Code extensions:

In your project directory (the one containing package.json), install the development dependencies:

	# Svelte 5

	This project uses the newer Svelte 5 instead of the more common Svelte 4.

	Version 5 comes with an overhauled syntax and reactivity system. While it may look different at first, you'll soon notice many similarities. This guide goes over the changes in detail and shows you how to upgrade. Along with it, we also provide information on _why_ we did these changes.

	## Reactivity syntax changes

	At the heart of Svelte 5 is the new runes API. Runes are basically compiler instructions that inform Svelte about reactivity. Syntactically, runes are functions starting with a dollar-sign.

	# Takes a video file and trims it to a specified time range, while also
	# adjusting quality for a smaller, shareable size.
	#
	# Example usage:
	# .\shrinkvid.ps1 video.mp4 00:00:10 00:00:20
	#
	# This will invoke ffmpeg with the following command:
	# ffmpeg -i "video.mp4" -vf scale=-2:720 -r 60 -crf 28 -ss 00:00:10 -to 00:00:20 "video_small.mp4"
	#
	# Make sure ffmpeg.exe is in your PATH

	// Use the `Buffer` class. Requires Node.js.
	import { Buffer } from "node:buffer";

	/**
	* @typedef CommodityPrice
	* @property {string} id - A unique identifier for this piece of information
	* @property {string} commodityId - The identifier for the commodity
	* @property {Date} postedAt - When this price was posted
	* @property {number} price - The price of the commodity when posted

	// A pattern I often find myself using consists of a report-type page that
	// displays any amount of data. At the top of that page is a `<form>` containing
	// one or more `<select>` elements whose purpose is to filter the data on the
	// report.

	// The form uses `method="GET"`, which is great to make sure that the URL stays
	// in line with what the page shows. A user can bookmark/favorite the URL and
	// come back to it later. A user can share the URL so other users can see
	// exactly the same page.

	git clone myusername@myserver:/home/git/myrepo

	# `myusername` is your username on the server which hosts a bare git repository
	# `myserver` is a `Host` configured in `~/.ssh/config` on your local machine
	# `/home/git/myrepo` is the path to the bare repository on the server

	cargo watch -c -w src -x run

	# -c : Clear the terminal before each reload
	# -w : Which files to watch
	# -x : What command to execute

	# cargo-watch must be installed.
	cargo install cargo-watch
