Folder Structure

Please note

While this gist has been shared and followed for years, I regret not giving more background. It was originally a gist for the engineering org I was in, not a "general suggestion" for any React app.

Typically I avoid folders altogether. Heck, I even avoid new files. If I can build an app with one 2000 line file I will. New files and folders are a pain.

Postviewer - writeup

Challenge's overview

The rumor tells that adm1n stores their secret split into multiple documents. Can you catch 'em all? https://postviewer-web.2022.ctfcompetition.com

The challenge consisted of an all client-side simple page, i.e. no backend code was involved. A user can upload any file which will be then locally stored in indexedDB. They can preview their files by either clicking on the title or by visiting file's URL, for example https://postviewer-web.2022.ctfcompetition.com/#file-01d6039e3e157ebcbbf6b2f7cb2dc678f3b9214d. The preview of the file is rendered inside a blob created from data: URL. The rendering occurs by sending file's contents to the iframe via postMessage({ body, mimeType }, '*')

Additionally, there is a /bot endpoint which lets players send URLs to an xss-bot imitating another user. The goal is to steal their documents.

In these two files if you change getToken{slow,fast}'s passed value (just add a random letter anywhere) you'll see that the fast version is getting type checked about 3x to 5x faster than the slow one.

I'm not sure why using key remapping and using keyof {} is about 3x to 5x faster when doing type checking.

My guess is that in the slow version is using index access with the {}[keyof Theme] which is generally slower?
