NGRX Store: Understanding State Selectors - Ultimate Courses
Selectors are pure functions that take slices of state as arguments and return some state data that we can pass to our components. To better understand what selectors are and what they do, it helps see ngrx state as a data structure - a tree that can be serialised to JSON. Data is added to the state tree by composing state in reducers - that’s the easy part. Now to get data out of the state tree,

Lazy Loading Angular - Code Splitting NgModules with Webpack - Ultimate Courses
Let’s talk about code splitting in Angular, lazy-loading and a sprinkle of Webpack. Code splitting allows us to essentially break our codebase down into smaller chunks and serve those chunks on demand, which we call “lazy loading”. So, let’s learn how to do it and some of the concepts/terminology behind it. Want the code? Go straight to GitHub or view the live demo The above .gif demonstrates lazy
Component architecture recipes for Angulars reactive forms - Ultimate Courses
Component architecture is the fundamental building block of applications, and isn’t just limited to Angular. Building with components allows for things such as encapsulation, isolation and reusability for a single or set of components. When dealing with forms, using components has typically been a challenge - and I’d like to share some patterns when creating reactive forms with Angular’s component
Introducing ngxErrors, declarative form errors for Angular - Ultimate Courses
What is ngxErrors? If you’re familiar with AngularJS (1.x) then you’ve likely stumbled across ngMessages. It’s a really tidy form errors module that allows you to declaratively add errors to your templates using a switch-statement style approach. ngxErrors is my stab at the beginning of achieving similar results using Angular (v2 and onwards), with a little more ease of use, less directives and ma
Mastering the Module Pattern - Ultimate Courses
I’m a massive fan of JavaScript’s Module Pattern and I’d like to share some use cases and differences in the pattern, and why they’re important. The Module Pattern is what we’d call a “design pattern,”and it’s extremely useful for a vast amount of reasons. My main attraction to the Module Pattern (and its variant, the Revealing Module Pattern) is it makes scoping a breeze and doesn’t overcomplicat
Understanding Angulars $scope and $rootScope event system $emit, $broadcast and $on - Ultimate Courses
Angular’s $emit, $broadcast and $on fall under the common “publish/subscribe” design pattern, or can do, in which you’d publish an event and subscribe/unsubscribe to it somewhere else. The Angular event system is brilliant, it makes things flawless and easy to do (as you’d expect!) but the concept behind it isn’t so simple to master and you can often be left wondering why things don’t work as you
Exploring the Angular 1.5 .component method - Ultimate Courses
AngularJS 1.5 introduced the .component() helper method, which is much simpler than the .directive() definition and advocates best practices and common default behaviours. Using .component() will allow developers to write in an Angular (v2+) style as well, which will in turn make upgrading to Angular an easier feat. Let’s compare the differences in syntax and the super neat abstraction that .compo
