Differences between NPM and NPX

Differences between NPM and NPX is simple if you keep it on paper. Meera uses it for install express in a new folder.

Keep Differences between NPM and NPX small. Meera should finish install express in a few lines, not a 40-line dump.

Without Differences between NPM and NPX, a new folder gets messy and install express is hard to trust.

Meera ships Differences between NPM and NPX in a new folder. That is the use case worth saying.

Differences between NPM and NPX trap — deleting package-lock blindly. Meera loses marks for that every viva.

Place Differences between NPM and NPX next to nearby Node.js work — npm init + npm i express is the link.

Viva for Differences between NPM and NPX: what it is → npm init + npm i express → the mistake (deleting package-lock blindly).

Exam tip

Board: install express. Dry-run Differences between NPM and NPX. Name the trap: deleting package-lock blindly.

Example

const pkg = {
  name: "demo",
  version: "1.0.0",
  scripts: { start: "node index.js" },
  dependencies: { express: "^4.19.0" },
};
console.log(pkg.name, Object.keys(pkg.dependencies));

Differences between NPM and NPX — package.json declares scripts and dependencies that npm installs.
