Scrape Market tags from http://angel.co/markets using CasperJS. This script is a basic example, and so it doesn't click any of the dropdown arrows or the 'More' buttons, so it only returns the top-level tags.

get_angel_tags.js

var utils = require('utils');

var markets_url = 'https://angel.co/markets';

var casper = require('casper').create({
    // verbose: true,
    // logLevel: 'debug',
    pageSettings: {
        loadImages:  false,
        loadPlugins: false
    }
});

casper.on('error', function(msg, backtrace) {
    this.echo("=========================");
    this.echo("ERROR:");
    this.echo(msg);
    this.echo(backtrace);
    this.echo("=========================");
});

casper.on("page.error", function(msg, backtrace) {
    this.echo("=========================");
    this.echo("PAGE.ERROR:");
    this.echo(msg);
    this.echo(backtrace);
    this.echo("=========================");
});

var markets = []

function getMarkets() {
    markets = document.querySelectorAll('div.item-tag');
    return Array.prototype.map.call(markets, function(e) {
        return e.innerText
    });
}

casper.start( markets_url );

casper.then(function() {
    markets = this.evaluate(getMarkets);
});
                
casper.then( function() {
    this.each(markets, function(self, market) {
        this.echo( market );
