globalThis and/or window

globalThis

If you like to stick things on globalThis.

• globalthis (npm link).
  • var globalThis = require('globalthis/polyfill')();
    • the usage of var there (rather than let or const) is appropriate (not just stylistic)
• MDN: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/globalThis

It took me a little bit to find this setting so I'm writing it down for friends.

After you finish a debug session in VS Code, it may change the sidebar's focus back to the File Explorer.

I don't think it is the default setting, but mine was set that way (and I didn't remember that).

To change it in your settings JSON:

what

Run an async function at the top level of your JS/TS module, using the IIFE pattern.

An async function expression can be used as an IIFE (Immediately Invoked Function Expression) which runs as soon as it is defined. MDN

why even make a snippet?

• I do this a lot when scripting/ testing stuff out, and there's something about typing it out that makes me lose my train of thought. (It's not to reduce my number of keystrokes!)
• This shows how you can make some easy Live Templates of your own

Lookin' for some JavaScript/TypeScript snippets for JetBrains?

Instead of looking for Sublime Snippets to import, get some Live Templates:

These live templates are based off of https://atom.io/packages/es6-javascript.

There's a plugin in the JetBrains marketplace that is broken in a peculiar way (at least on my machine), that makes it so it doesn't work and it is invisible/ can't uninstall it with the Preferences GUI.

In this case it's a plugin called stackoverflow. I reported the bug but this works for other plugins as well.

Back up your settings (and settings folders) before you mess with them.

To remove a plugin from all JetBrains IDEs:

From the cht.sh README:

ZSH Tab completion

To activate tab completion support for cht.sh, add the :zsh script to the fpath in your ~/.zshrc:

    $ curl https://cheat.sh/:zsh > ~/.zsh.d/_cht
    $ echo 'fpath=(~/.zsh.d/ $fpath)' >> ~/.zshrc
    $ # Open a new shell to load the plugin

Error when running rails db:migrate:

undefined method `str' for #<ActiveRecord...>

Solution is so trivial it took me a bit. I accidentally put foo:str instead of foo:string, in the arguments to rails generate .... So, just re-run with the correct field type name.

What's a Uniform Type Identifier?

Each UTI provides a unique identifier for a particular file type, data type, directory or bundle type, and so on. In addition, other type identifier namespaces for a particular type can be grouped under one UTI, with utility functions available to translate from one format to another.

What's the table below?

The following tables list uniform type identifiers (UTIs) that are declared by the system as of OS X v10.4. [Which was released in 2005. That means it's NOT up to date. Apple Developer stuff has the up to date docs. Still, these can be useful for scripting, Alfred Workflows, and so on.]
