Using the node Command

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*
