run terminal commands in node js

Question

I'm trying to write a web crawler program using quickscrape, after I type

quickscrape \
  --url https://peerj.com/articles/384 \
  --scraper journal-scrapers/scrapers/peerj.json \
  --output peerj-384
  --outformat bibjson

and hit the "Enter" in my terminal, the library will generate the result from the crawler and put them into a folder.

Now I want to write a javascript progarm so that is will call these terminal commands for me, but I am not sure how to interact with terminal in node.js.

I think child_process is that you need. https://nodejs.org/api/child_process.html

let exec = require('child_process').exec;
exec('quickscrape --url https://peerj.com/articles/384 --scraper journal-scrapers/scrapers/peerj.json --output peerj-384 --outformat bibjson', (error, stdout, stderr) => {
    //...
})
