Real world example code for popular front-end and back-end frameworks

Its a great tip regarding example code for popular web frameworks (also mobile in the works), for example ASP.NET Core on the backend side and Angular or Vuejs on the frontend side etc. See list of backends and frontends here: (scroll down there are many options…) 

Building software applications is hard, but doing it in isolation is even harder.

And, unless you’re one of the fortunate few who work in a perfectly balanced team with just the right amount of experienced developers to lean on, you’re often left figuring all this stuff out for yourself.

· Architectural best practices

· How to organise your code

· How to separate your concerns

· Which ORM to use

· How to KISS (keep it simple stupid) and avoid incurring loads of technical debt

But, just because you haven’t got a supportive, experienced and wise team physically on your doorstep doesn’t mean you have to re-invent all the wheels yourself!

Specifically I really want to recommend you check out the “real world” examples over at

There, they take the exact same application (a Medium clone) and show examples built in all manner of front-end and back-end frameworks.

So if you’re looking to see what a good ASP.NET Core API application looks like (or React, Angular, Vue.js or anything else you can think of)

npm vs Yarn – Which Package Manager Should You Use? – KeyCDN

npm and Yarn are two well-known JavaScript package managers. If you’re not familiar with what a package manager does, it essentially is a way automate the process of installing, updating, configuring, and removing pieces of software (AKA packages) retrieved from a global registry. In this post, we’ll be going over what differences exist between two of the most popular JavaScript package managers – npm and Yarn.

Bootstrap 4 truncate-text responsive classes SASS helper

I needed to truncate text in certain device sizes in a Bootstrap 4 enabled site.

Bootstrap comes with the text-truncate css class that will truncate text in elements that are in displayed as block or inline-block.

There is no support for targeting the different viewports out the box.
Here is solution for this;


We want the text of this element to truncate (Shorten the text if it doesnt fit and  adds … to the end of the text) on smaller devices:


Include this scss file to your site:


Image object fit fallback polyfill for Internet Explorer and Edge

Here is a way to make object fit for images behave similarly in Internet Explorer and Edge.

The basic idea is that we have an img  that we want to scale into different sizes but also proportions (e.g get wider or higher than the original image).

We allow some clipping occur to enable this. This is especially useful in responsive website where you need to support different viewports and perhaps number of columns for a list of images etc.

More info here and examples of clipping of image etc:

We use this css styling to enable that on the img element:

Unfortunately object-fit is supported by all major browsers except Internet Explorer and Edge. A way to make it work in those browsers is to copy the image src to the image container element and use the background* css propeties instead.

The code and idea is taken from here:

I have tweaked the above example a bit and here is my version of it. See comments section in the link above for plain js versions etc.


We mark the img with the class “img-cover”:

Download here:

The js has dependencies on jquery 3.2.1 and modernizr 3.6 (I have tested with those versions).

The html should look like this when the polyfill is working in Internet Explorer or Edge:

The container (a-element) gets the compat-object-fit class and inline style background image is copied from its contained img src. Also the css file will set the contained img to opacity 0 in favor of container bg image instead.
