Cheng Lou - On the Spectrum of Abstraction

Cheng Lou, a former member of the React team, gave an incredible talk at React Europe 2016 entitled "On the Spectrum of Abstraction". That talk is available for viewing here: https://www.youtube.com/watch?v=mVVNJKv9esE

It's only a half-hour, but it is mind-blowing. It's worth re-watching two or three times, to let the ideas sink in.

I just rewatched the talk for some research, and wrote down a summary that's semi-transcript-ish. I didn't see any other transcripts for this talk, other than the auto-generated closed captions, so I wanted to share for reference.

If you are developing React native based Android App and using XIAOMI/MIUI Device, this tips might help you to get rid some headache when debugging the app

Enabling Developer Menu

To enable Developer Menu, you need to tag 7 times on MIUI Version under About Phone Setting menu instead of Build Number. The Developer Menu can be found on Additional Settings

Can't Install Debug APK? "...Failed to establish session"?

1. enable developer mode - In your phone, go to Settings, About phone and click on MIUI version 7 times. You’ll see a pop up which says you are a developer now.
2. Go back to Settings, Additional settings, Developer options and enable USB Debugging.
3. Connect your phone to your PC/Mac and on the phone authorize your computer

Migrations & Seeding

What are migrations??

Migrations are a way to make database changes or updates, like creating or dropping tables, as well as updating a table with new columns with constraints via generated scripts. We can build these scripts via the command line using knex command line tool.

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.
