Preact, Without Build Tools

This is a demonstration of using Preact without any build tooling. The library is linked from the esm.sh CDN, however a standalone JS file exporting HTM + Preact + Hooks can also be downloaded here.

  This gist was created to demonstrate my idea for removing selectors from his query syntax.

Using server-sent events

Why and how?

• Documentation: https://web.dev/articles/eventsource-basics
• Use case: broadcasting data from server to browsers
• Benefits:
  • Easy to understand and implement (only a few lines of code)
  • No library is needed
• Can use same HTTP(S) authentication as elsewhere in the app (which can’t be done with websockets)

The Rules of React

All libraries have subtle rules that you have to follow for them to work well. Often these are implied and undocumented rules that you have to learn as you go. This is an attempt to document the rules of React renders. Ideally a type system could enforce it.

What Functions Are "Pure"?

A number of methods in React are assumed to be "pure".

On classes that's the constructor, getDerivedStateFromProps, shouldComponentUpdate and render.

What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would
