node

Server-side JavaScript platform (Node.js). More information: https://nodejs.org.

  • 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 "{{code}}"

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

node -p "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}}
