npm run dev
Definition
npm run dev is a terminal command that runs the project's development script from package.json. In many web projects, it starts a local development server so you can view and test the project in the browser while you work.
Why beginners see it
Beginners often see npm run dev early because it is part of the normal local development workflow. It is the command that helps you open the project on your own machine before anything is deployed.
Example in VCA
At Vibe Code Academy, students often run npm run dev after npm install so they can open the localhost address shown in the terminal and check their work as they build.
