Argument parsing

Resources

• Accept arguments from the command line on the Node.js Learn site

Code

Basic

Use process.argv. Drop the first two arguments, which are the path to Node and the current script.

const args = process.argv.slice(2)
console.log(args)

Example usage:

$ node app.js foo --bar=bazz

[ 'foo', '--bar=bazz' ]

Keyword arguments

You need a package like minimist to parse key-value pairs for you.

const minimist = require('minimist')

const args = minimist(process.argv.slice(2))
console.log(args['name'])

Example usage.

$ node app.js --bar=bazz
