Custom ES6 errors in Node.js
View nodejs-custom-es6-errors.md

Here's how you could create custom error classes in Node.js using latest ES6 / ES2015 syntax.

I've tried to make it as lean and unobtrusive as possible.

Defining our own base class for errors

Important: At the time of writing (2019-11-11) Immutable.js is effectively abandonware, so I can no longer recommend anyone to follow the advice given here. I'll leave the article here for posterity, since it's still getting some traffic.

Understanding Immutable.Record

Functional programming principles and with it immutable data are changing the way we write frontend applications. If the recent de-facto frontend stack of React and Redux feels like it goes perfectly together with immutable data, that's because it's specifically designed for that.

There's several interesting implementations of immutable data for JavaScript, but here I'll be focusing on Facebook's own Immutable.js, and specifically on one of i

In the latest TiAlloy you can specify a module tag against the <Alloy> element in XML and this will be used when creating any elements in the view, so you can override, customise etc. The problem is if you want to use multiple commonJS libraries, there's no support in the Alloy Tag -- you'd have to change the module attribute for each element --…
View elements.js
var o = {};
// include the modules you want - purposely did this as seperate lines so it's easier to comment out modules etc
_.extend(o, require("module1"));
_.extend(o, require("module2"));
_.extend(o, require("module3"));
// make available under a single export for use in <Alloy> tag
module.exports = o;

Inject environment variables into Titanium. Makes shared code easier to manage (no more sanitizing keys in repos). Uses Titanium to encrypt the values.
View app.js
// now you can use it in a titanium app
useSomeApi(Ti.App.Properties.getString('SOME_API_KEY'));

inheriting event handlers in Alloy
View base.js
// The base controller event handler, which will get overridden by the derived one
exports.doClick = function(e) {
alert('base click handler');
};
// We have to wait until the object is initialized before applying the event listener. This is so
// the derived listener is used, not the base one. Also, "$" must be used instead of "exports", to
// ensure that the overridden instance of the controller's "doClick" is used, not the exported
// version of the function from the base controller.
exports.init = function(e) {
