A Gentle Introduction to Prepack, Part 1

Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

  • Babel lets you use newer JavaScript language features, and outputs equivalent code that targets older JavaScript engines.

lit-html is awesome, but it came afterwards

The history of hyperHTML followed by lit-html

While many remember the epic hyperHTML: A Virtual DOM Alternative post I've published the 5th of March 2017, the first official implementation of the library was working as hyperHTML.bind(node) function for tagged literals the day before, and it's been in my experiments folder already for a little while.

The hilarious reaction from the skeptical community

At first glance people couldn't believe performance of the DBMonster demo shown in that article,

<template>
<div id="app">
<p>
Pending: {{ $store.state.getInfoPending }}
</p>
<p>
{{ $store.state.getInfoData }}
</p>
</div>
</template>

Adb useful commands list
Hi All!
I've recently launched a tool that wraps many of the commands here with a user interface. This desktop application is currently available for macOS. There's a roadmap outlining planned features for the near future.
Feel free to request any features you'd like to see, and I'll prioritize them accordingly.
One of the most important aspects of this application is that every command executed behind the scenes is displayed in a special log section. This allows you to see exactly what’s happening and learn from it.
Here's the link to the repository: https://github.com/Pulimet/ADBugger
App Description:
ADBugger is a desktop tool designed for debugging and QA of Android devices and emulators. It simplifies testing, debugging, and performance analysis by offering device management, automated testing, log analysis, and remote control capabilities. This ensures smooth app performance across various setups.

Comparison of Monorepo Tools For Web Client / Front End Projects (That Probably Use HTML, CSS, and JS)

Mono Repository Tool Comparison

For Web Client / Front End Projects

(That Probably Use HTML, CSS, and JS)

I made a list of 20 things I might want out of a monorepo tool for a Design System to use as a basis for comparing some of the options including Lerna, Northbrook, and Rush.

⚠️ Northbrook's author says the project is pretty dead and now uses Lerna.

Qualifications Wanted
