I'm using svelte 5 instead of svelte 4 here is an overview of the changes.

Overview

Svelte 5 introduces runes, a set of advanced primitives for controlling reactivity. The runes replace certain non-runes features and provide more explicit control over state and effects.

$state

• Purpose: Declare reactive state.
• Usage:

<script module>
  /*
   Sample usage:
   
   ```svelte
   <script lang="ts>
     import AppRouter, { type Router } from "./AppRouter.svelte";
     import Login from "./pages/Login.svelte";
     import Home from "./pages/Home.svelte";
     import Messages from "./pages/Messages.svelte";

Chromium on Vercel (serverless)

This is an up-to-date guide on running Chromium in Vercel serverless functions in 2022. What you will read below is the result of two days of research, debugging, 100+ failed deployments, and a little bit of stress.

Getting started

Step 1: Install dependencies

Use chrome-aws-lambda that comes with Chromium pre-configured to run in serverless, and puppeteer-core due to the smaller size of Chromium distributive.

// Encodes a js object as a url-safe base64 string.
encodeURIComponent(btoa(JSON.stringify({ ... })))

// Takes the previously generated string and returns a parsed js object.
JSON.parse(atob(decodeURIComponent('...')))

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

XCTest and Optional Unwrapping

XCTest is the default test harness on iOS an Apple’s other platforms. It provides support for organizing test cases and asserting expectations in your application code, and reporting the status of those expectations. It's not as fancy as some of the BDD frameworks like Quick and Cedar, but it has gotten much better than it used to be, and is my preferred test framework these days.

The Problem

One place where the XCTest assertion utilities fall a bit short has been with managing Optional variables in swift. The default use of XCTAssertNotNil don't provide any mechanism for unwrapping, easily leading to assertion checks like this:

class TestCaseDefault: XCTestCase {

There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules directory) as well as files that are generated (and regenerated) as artifacts of a build process.

All other files should be in your own global gitignore file:

• Create a file called .gitignore in your home directory and add any filepath patterns you want to ignore.
• Tell git where your global gitignore file is.

Note: The specific name and path you choose aren't important as long as you configure git to find it, as shown below. You could substitute .config/git/ignore for .gitignore in your home directory, if you prefer.
