I started using React Native in September 2018. I always forget some things when I build new apps, so I'll keep track of the gotchas on this post.

Some topics, such as navigation, will be fundamental to how I think about apps. Others, will be one-line helpers that make apps work more smoothly.

It's gotten to the point where I find my own answers from 6 months before on certain Github issues.

I'll keep adding over time as I think of more. If anyone thinks these topics would be useful, let me know and I'll elaborate.

I have made libraries to address a number of the topics here, from navigation to design.

So there were a few threads going around recently about a challenge to write the longest sequence of keywords in Javascript:

• https://twitter.com/bterlson/status/1093624668903268352
• https://news.ycombinator.com/item?id=19102367

There are, however, a few problems:

• These solutions use non-keyword tokens (null, true, false are actually Literals, not Keywords)
• One of the solutions isn't quite valid (new super)

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.
