Web Development Without a Framework

How difficult is it to assemble the pieces you need

As President Kennedy implored:

“My fellow developers, ask not what your Framework can do for you. Ask what you can do for your framework!”.

Yeah, I know, not quite the exact quote. But sometimes it feels that you have to do more to help your framework work than your framework does to help you.

Two years ago I was working with Angular 2 and if you managed to get your compressed javascript payload under 200Kb you thought you were doing pretty well. I remembered about it when I realized I can now have an app with far more functionality and be easily within 15Kb.

Maybe it’s time to ask yourself, what is your Framework really doing for you … and do you still need it?

How WebComponents Make Site Upgrading Easier

Because switching Frameworks is hard

While we’re used to systems nowadays being distributed and running across multiple services on multiple platforms when it comes to front-end web clients many people still have a rather “monolothic” outlook on things.

Many times this is down to technology imposing restrictions on us - it’s difficult enough to make some frameworks and all their component pieces work together to deliver an app without also throwing in the challenge of making multiple different frameworks coexist (part of the problem with the rise of “frameworks” instead of libraries).

It can be particularly problematic when an aging app needs to be upgraded. You may have an Angular.JS app and be faced with the choice of whether to re-write it as an Angular v2 / v4 app or switch to using the Redux / React stack instead.

Both represent a lot of work and the difficulty making frameworks coexist can be a real challenge with any attempts at doing things incrementally. This is where WebComponents can really help.

Angular2 DI Service Decorator

How Dependency Injection is meant to work

Dependency Injection or ‘DI’ is a mechanism used within Angular2 to provide instantiated services or other objects to the components (and other services) that need them. It allows a class to ask for just what it needs without needing to know about the entire tree of dependencies in order to create them itself.

The idea of DI is based on design principles intended to help us write better, cleaner and easier to maintain software. Unfortunately, there are certain limitations in the implementation of the Angular2 DI system which mean it’s not always obvious how to get all the benefits we should.

So, we’ll explore these principles using DI with the Http and an AuthHttp implementation as an example to show how it is still possible to achieve.

Angular2 New Component Router Review

My experience of using it

What makes a good client-side router? What do we even want a router to do? What is Angular2’s Component Router like and should you plan on using it?

I’ll share my own thoughts on this based on my experience of using it so far.

First thought, we need to understand why we use a javascript router in the first place. Some of this may seem “duh” basic but it’s often worth taking a step back in order to evaluate exactly where we are.

Angular2 Route Security

Restricting access based on auth state or roles

Once you move beyond the quick-starts and examples and start building a real app with Angular2 you soon find you need to handle things that the examples often leave out or pass over.

Securing routes with the new component router is one of these and it can be difficult to figure out. Here’s the approach I’m using which seems to be working well for me and has been reusable across multiple projects.
