Feeding Data in NodeJS

I used to work the library readline when I wanted to feed data into a nodejs command line application. Now I found a slightly niftier solution by using a library called split.

Code of the Day

This is how you do it:

// we stream the input and send the messages ones by one.
const split = require('split');
const input = process.stdin.pipe(split());

input.on('data', (line) => {
    if(line) {
        console.log(line)
    }
});

notice the if(line), this is because when feeding data I usually get an empty line at the end.
