About

Node.js runs JavaScript away from the browser. It reaches files, the network and the operating system. Use it for servers, command-line tools or front-end build steps.

Install it

pkg install nodejs-lts

Run this inside Termux. If the package is already present, pkg will say so and do nothing.

Commands worth knowing

5 of the invocations you will actually reach for. Tap the copy button to put one on your clipboard.

node script.js Run a saved JavaScript file and print its output. Test a script before wiring it into anything.

node -e console.log(process.version) Evaluate a short snippet straight from the command line, without creating a file.

node -v Print the installed runtime version. Useful when a package demands a minimum.

node --check script.js Parse a file for syntax errors without running it.

node -i Open an interactive prompt, where you can try expressions one at a time.

Worked example

Run node -p process.versions and this is what you should see.

termux

$ node -p process.versions
{
  node: '20.11.1',
  v8: '11.3.244.8',
  uv: '1.46.0',
  openssl: '3.0.13'
}

The runtime reports the versions of its key components.
