Did you know that a wrong SCSS usage can increase the bundle size of your Angular application? And you know what this issue is, right? A performance issue!! The bigger the bundle size the more time the browser requires to download all the files and the more time it takes to paint the page.
A side note here: The CSS is render blocking which means that the browser won't render anything until all the CSS is downloaded and the CSSOM is constructed.
Having this in mind, we have to take extra care of our CSS. Don't we? :)
The majority of the products I worked on was/is B2B and they consisted of many (MANY) web forms. You know how this goes.
Who is our best friend for situations like this? ctrl+c & ctrl+v :) Yeah I know. I've been there.
Someone might say that this "best friend" helps us in many different cases. Here a bell rings. What do you do when you have to re-use the same code again and again? The answer is Abstraction.
You know how to abstract your code in JS, in TS in C# and in many other languages. What about HTML though? Continue reading to find this out :)
Developing an application in Angular CLI is really fun and fast due to its nature and the features it offers to developers. One of the great features it has, is the ability to run your code using different variables. Similar to environmental variables that are distinguish per se. But what are the environment variables and what is the relation with the ionic?
Have you ever had the need two components to communicate each other? Of course you had!
I bet that when you hear components communication or components interaction, you automatically think of @input @output decorators.
Say that we have two components, parent and child. You want the parent component to interpolate on its template a property from the child component. How can we do this?
In this post we will try together to build a form consisted of different components and we will try various implementations to achieve the best architecture. The final pattern that we will implement is the smart dumb.
We will try 4 different approaches and soon I will create a 5th one which will use the exportAs.
The post is quite long but it worth's diving in :)
Our form will have:
The protractor.conf.js file is meant to offer a configuration for our e2e tests. The default which come with each new angular-cli app is very good and works really well. We shouldn't extend it unless we expect more.
Although it works well on localhost, what about the CI server?
On this post I wont explain what kind of configuration you might need for your CI, but how to separate the configuration and how to use it
As web developers we have been developing web forms almost on every app. How many times have you spent time searching on google (or bing - no offense ) on finding solutions to pre-select an option on a select control while using angular? Yeah I know! Many times. And when you read the solution you are like "Ohh yess!"
Let's demystify this
