It doesn't make sense upon initial description reading, but there is a use case for it... Updating a package.json dependency to use a caret without getting the latest semver match.

I'm currently working on a very large project, in which we would like to enforce exact version matches across all child workspace package.json files.

Understand that when I say child workspace packages, you mustn't assume this project is a monorepo that publishes its packages. It uses yarn workspaces simply for the benefit of doing non-relative-path imports:

import { thing } from 'internal-package-a'
// vs

Deep Imports

Description

A "deep import" is simply an ESM import that goes deeper than the package root:

import thingA from 'my-package-name/src/components/thingA'
import thingB from '@my-namespace/my-package-name/src/components/thingA'

const axios = require('axios')

const userToken = '<user token>'
const devToken = '<dev token>'

/**
 * Gets a distinct array of the artists in a user's playlists
 * @param {string} devToken The Apple-issued JWT developer token
 * @param {string} userToken The returned Apple `musickit.authorize()` user token

LESS/SASS Guidelines

Structure. Structure. Structure

Make sure structure is organized and created in such a way that accommodates a large project by properly categorizing and modularizing folders and files. It’s better to feel that you’re over-engineering at the beginning, and restructure “down” later, than to assume a minimal set-up up front, simply for the sake of expediency.

Bad:

Git commands

Note: Always make sure you're in the project root when doing git commands, or else it won't see the .gitignore file and try to track files that should be ignored.

To reset your files back to the last commit:

git reset --hard HEAD

ID or Class selectors with capital letter(s):

Hard-coded hex values (3 or more characters):

#[A-Fa-f0-9]{3,}

Hard-coded @media query viewport numbers (i.e. 768px), instead of $variable

@media[^\{]+[0-9]+px[^\{]+\{

No space after colon in "attr:val;"
