Decompile JavaScript from source maps

Overview

Modern JavaScript build tools compile entire folder structures of JavaScript code into single, minified files that are near-impossible to read, but can also include source maps which can be used to display the original code in tools such as the Chrome DevTools Sources panel.

These source maps can be processed to extract mainly meaningful code and file structures, by installing a package calling Shuji and running a simple bash command.

Generally, production builds shouldn't include source maps, but if you do manage to lose your source files, or for some (obviously, ethical!) reason need to view the original files, and you happen to have / find the source maps, you're good to go.

CUSTOM GAME ENGINES: A Small Study

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like Unreal or Unity for their games (or that's what lot of people think) because d

Serverless plugin author's cheat sheet

This cheat sheet provides a detailed overview of the exposed lifecycle events and available commands (and entrypoints) of the Serverless framework, that can be hooked by plugins (internal and external ones). The document is structured by the commands invoked by the user.

Lifecycle events are shown as the globally available outer events (all providers) and sub lifecycle events that are provider specific in the called order. Currently only the AWS provider is shown. If you have information about the other provider,
