# npx vs npm
2+

```sh
4+
npx <command>
5+
```
6+
7+
Executes `<command>` either from a local node_modules/.bin, or from a central cache, installing any packages needed in order for `<command>` to run.
8+
9+
By default, `npx` will check whether `<command>` exists in $PATH, or in the local project binaries, and execute that. If `<command>` is not found, it will be installed prior to execution.
