Let's say we use angular 5 or greater and we want to track clicks outside of specific elements. And even more. Sometimes we need to track outside clicks which happened only on specific area.

I looked for analogues for gitlab because of some issues which I experienced while managing my git repos with it.

I stopped on gogs because it is more lightweight and works much faster comparing to gitlab-ce.

Here is a short note of how to get dockerized gogs running.

Mongoose does not have a possibility to configure your schema to transform nested arrays of objects. In this post we will look at a possible workaround for this.

In 1970s Manny Lehman a set of Lehman's laws of software evolution. These laws only apply to a certain type of systems so he divided the systems into three categories:
- E-type
- P-type, and
- S-type systems

Let's talk about primitive obsession. So primitive obsession is when you are using primitives to represent domain concepts. We'll talk about examples, but let's first talk about it.

So let's start with the question what is a domain concept.

Let's talk about CQS (command query separation). Command query separation is a term first formulated by Bertrand Meyer who is the creator of "eiffel" programming language. Command query separation essentially states that you should separate your queries from your commands. Is is kind of intuitive name right? But what does that actually mean?

Let's first get it clear that what we are talking about in this post is methods.

Let's say you try to move some existing project to lazy loading modules using "loadChildren" property of your routes.
In this post you can find few typical errors which you may get while moving angular 2 project to lazy loading modules in routes.

Example of drag and drop directive implementation in Angular2+. Includes example with HostListener and a bit better example with NgZone.runOutsideAngular

This part of notes covers following topics: using css4 variables, using currentColor reference, using gradients for creating interesting backgrounds, implementing inner rounded corners without extra html, etc.

There are two types of how variables can be redefined in sass:

- Simple redefinition by assigning the value after initial assignment
- "Lazy" definition, in case if value of variable was not defined previously, otherwise current definition statement is skipped. Special syntax exists for this option, it is "!default"

Turn of magnification - one or another feature of product is worth to be separated to a standalone product.

Sometimes it is great to have possibility to create custom form elements in angular 4.
Let's not waste time and look at how it is done by example for the case when we want to access values from "contenteditable" div.

Let's create a custom value accessor directive for contenteditable div.

Since angular 2 rc5 dynamic components instantiated via "ComponentFactoryResolver" should be obligatory declared in "entryComponents" declaration of containing module. This can be an issue because we may want to generate component on fly. So let us look at how we can find a workaround for this.

Knex looks like the best option for database migrations in node from my point of view right now. Let's have a fast look into it.

There is an extremely effective way to make your content loading faster.
Here are tools for that ordered by their coolness:
- dns-prefetch - execute domain resolution in background
- preconnect - execute domain resolution plus tcp handshake, plus executes TLS handshake for SSL
- prefetch - fetches resource in background. Resource is fetched with a lower priority, and only after common resources load is finished. Prefetched content is stored in cache.
