npx

ELI5 — The Vibe Check

npx is the 'try before you buy' of the npm world — it lets you run a package without permanently installing it. Need to scaffold a new project with create-react-app? npx handles it without cluttering your global installs. It's like renting a power tool instead of buying one you'll use once. It also runs locally installed packages without the ./node_modules/.bin/ path dance.

Real Talk

npx is a CLI tool bundled with npm (v5.2+) that executes packages from the npm registry or local node_modules without global installation. It resolves and runs binaries from packages, caches them temporarily, and supports version-specific execution. It's commonly used for project scaffolding, one-off tools, and running local binaries.
