Problem

How to use the node command: Server-side JavaScript platform (Node.js). More information: <https://nodejs.org/docs/latest/api/cli.html#options>.

Solution

node — Server-side JavaScript platform (Node.js). More information: <https://nodejs.org/docs/latest/api/cli.html#options>.

Run a JavaScript file:

node {{path/to/file}}

Start a REPL (interactive shell):

node

Execute the specified file restarting the process when an imported file is changed (requires Node.js version 18.11+):

node --watch {{path/to/file}}

Evaluate JavaScript code by passing it as an argument:

node {{[-e|--eval]}} "{{code}}"

Evaluate and print the result, useful to print node's dependencies versions:

node {{[-p|--print]}} "process.versions"

Activate inspector, pausing execution until a debugger is connected once source code is fully parsed:

node --no-lazy --inspect-brk {{path/to/file}}
