Parse output of spawned node.js child process line by line

Question

I have a PhantomJS/CasperJS script which I\'m running from within a node.js script using process.spawn(). Since CasperJS doesn\'t support require()

Answer 1

I found a nicer way to do this with just pure node, which seems to work well:

const childProcess = require('child_process');
const readline = require('readline');

const cspr = childProcess.spawn(bin, args);

const rl = readline.createInterface({ input: cspr.stdout });
rl.on('line', line => /* handle line here */)
