Use npm When
You are installing dependencies, managing versions, or running package scripts.
You want a package to become part of the project or global environment.
Compare
npm vs npx
The difference between the package manager itself and running package binaries on demand.
`npm` manages packages, scripts, and your dependency graph. `npx` runs package binaries, often without requiring a permanent local installation first.
Use npx When
You want to run a tool once without committing to an install.
You are using a package binary such as a scaffolder or formatter command.
Rule of Thumb
npm manages. npx executes.
