How to read user input directly in Node.js [duplicate]

Question

From the following code I can read and console.log the line

const readline = require('readline'); const { stdin: input, stdout: output } = require('process'); const rl = readline.createInterface({ input, output }); rl.question('What is your name? ', (answer) => { console.log(`Hi ${answer}!`); rl.close(); });

But I am trying to read user input like this Input: node app.js John Ouput: Hi John!

How can I achieve this in node?

Did you read e.g. nodejs.org/en/knowledge/command-line/…?

To achieve that you can use the following:

process.argv

process.argv is an array containing all arguments that were used when invoking you programm. Image you called your programm like that: node index.js "John", process.argv would look like this: ["node", "path/to/index.js", "John"].
