Kickstarter Spending Report

Kickstarter Spending Report README.md

I wanted a quick way to see how much I'd spent on Kickstarter. These browser console scripts will convert all Kickstarter pledges to your home currency and add them up.

1. Set homeCurr in xe.com.js and kickstarter.com.js to the same value.
2. Run xe.com.js in a console window on http://xe.com.
3. Set exchg in kickstarter.com.js to the output of step 2.
4. Run kickstarter.com.js in a console window on https://www.kickstarter.com/profile/backings?ref=nav.

You should see something like:

You have spent 1711.63976 USD on Kickstarter.

var homeCurr = 'usd';
var exchg = {"gbp":1.71194,"aud":0.93841,"cad":0.93808,"eur":1.36015,"nzd":0.88145,"usd":1} ;

function mapPledge () {
	return {
		curr: (this.innerHTML)[0] == '£' ? 'gbp' : this.className.replace(/^.* /, ''),
		amount: this.innerHTML.substring(1)
	};
}

function reduceCurrency (a, v, i, arr) {
	var amt = Number(v.amount) * exchg[v.curr];	
	return a + amt;
}

function waitForBackings() {
	if ($('section#collected a.show_more_backings:visible').length == 0) {
		var spending = $('section#collected table td:nth-child(2) span.money').map(mapPledge).toArray().reduce(reduceCurrency, 0);
		console.log("You have spent " + spending + " " + homeCurr.toUpperCase() + " on Kickstarter.");
	} else {
		setTimeout(waitForBackings, 500);
	}
}

$('section#collected a.show_more_backings:visible').click();

waitForBackings();
