Get Node.js Command Line Arguments with yargs
Using command line arguments within Node.js apps is par for the course, especially when you're like me and you use JavaScript to code tasks (instead of bash scripts). Node.js provides process.argv
but that doesn't provide a key: value
object like you'd expect:
/*
$ node myscript.js --key1=value1 --key2=value2
[ 'node',
'/path/to/myscript.js',
'--key1=value1',
'--key2=value2' ]
*/
Bleh. If you want to work with a sane API for command line arguments, use yargs:
// Get the yargs resource
var yargs = require('yargs').argv;
// Check for arguments
if(yargs.someKey === expectedValue) {
// Do whatever
}
/*
yargs = {
key1: value1
key2: value2
};
*/
yargs provides a key:value
object for arguments instead of the native process.argv
mess. No hassle, no fuss, just access to command line arguments with a logical API. Happy noding!
