Get package.json version from CLI

Using NPM

npm info . version
npm info /my/npm/project/path/ version

Use the npm info command to point to the folder where your package.json resides.

Using Node

node -p -e "require('./package.json').version"

The -p argument prints the result and the -e argument expects executable JS to follow it. This one is also helpful for getting specific properties from any JSON file.

Lodash in Shell

When both Node and Lodash are installed, they can be executed in shell scripts:

CHEESE="Camembert of Goat"
CAMEL_CHEESE=$(node -p -e "require('lodash').camelCase('${CHEESE}')")
KEBAB_CHEESE=$(node -p -e "require('lodash').kebabCase('${CHEESE}')")
echo $CAMEL_CHEESE # camembertOfGoat
echo $KEBAB_CHEESE # camembert-of-goat

Chrome Tabs Keyboard Shortcuts

When Chrome introduced Tag Groups, it was a big organizing aid. I found there were a couple things missing to make it really productive: keyboard shortcuts.

Omniscience

The RULIAD may be defined as the entangled limit of everything that is computationally possible.

TED Talk: Computational Universe

During a typical day, I would change to the main branch, pull the latest from the remote, delete the merged branches. Over and over all day, every day of the work. Now instead of all that checkout and pulling, I made a Git JERK!

Git -Xours -Xtheirs arguments

Git provides a helpful argument to prefer one branch or the other to “clobber” merge conflicts:

git merge main -Xours
git merge main -Xtheirs

I always get confused what the “X” means. I always assume “X” means mark which branch to clobber. Like “X” out their branch. Or “X” out our branch. Please wipe this mnemonic from your brain!

“X” means “PREFER”

“PREFER” the changes in their branch (-Xtheirs) or “PREFER” the changes in our branch (-Xours).

Jeez!

Await Timeout

(async () => {
  await new Promise(resolve => setTimeout(resolve, 500));
  ...
})();

Found on SO.

Extend URLSearchParams to object

There must be a reason this is a bad idea or it would be included in the API, right? 😅

URLSearchParams.prototype.toObject = function() {
  return […this.keys()]
    .reduce((o,k) => ({ …o, [k]: this.get(k) }), {});
}

Git Rollback Alias

Related to the Alias for Git sanity post from a few years back, recently added another to ~/.gitconfig

[alias]
  revert-merge = !git revert -m 1 $1
  rollback-merge = revert-merge

Where $1 is the commit hash. This only works for rollback of a merge commit on the main branch.
