Setting up Material Design with Angular 6

By Carbon Rider in Angular, Articles 0 Comment

Material Design started in 2014 and it was introduced by Google to provide a consistent look and feel across browsers. It combines animation effects with soothing colors, shadows, aptly measured margins/padding etc to improve the User experience. Back in the era of Flash/Flex, components designed using Flex has a visual appearance which felt natural. Without any need of adding styles, the plain Flex User Interface felt good. HTML components were lacking such natural appearance. Maintaining consistency across the browser was always a pain. With Material Design the UI aesthetics and interaction has improved dramatically.

Though Angular CLI enables you to quickly get started with creating a new project, it doesn’t come bundled with the Material design. Additional steps are required to integrate the Material Design and apply the styling to the components. In this article, we will learn the steps to integrate Material Design in Angular 6. We will extend this article and build following UI to understand some of the Material Design Components.

Serverless architecture – you might have already heard this term. But have you tried to build one? And do you understand what Serverless architecture really means? Typically a web application requires an infrastructure to host Web Server, Application Server, and Database Server. Traditionally organizations had either their own datacenters or rented servers to manage such requirements. With Cloud – Pay as you use model has gained a lot of popularity. The headache of managing physical infrastructure has been moved to vendors like Amazon, Microsoft, and Google. Given all that, your team is still responsible to provision, monitor and manage the servers.

With Serverless Architecture, Organizations gain total freedom from managing infrastructure and can focus on building functionality. The need for scaling, patching and provisioning servers is opaque to the development team, rather it is a responsibility of a Cloud Vendor. In this article, we will build a Serverless architecture with a Dynamic Web Application using Angular, AWS S3, Lambda, DynamoDB, and API Gateway.

CSS Modules with Webpack 4

By Carbon Rider in Articles 0 Comment

Ok, I know what you are going to say. We have heard of modules with Programming languages, but modules in CSS. Is that even possible? and why do you need it at first place? Well, I had a similar reaction when I heard about it. CSS Modules were born out of the idea of relentless hours spent in debugging issues caused by overlapping CSS selectors, class names.

The web projects include multiple CSS files to define common layout appearance, widgets etc. This sometimes becomes a nightmare when you have multiple CSS files sharing same class selector.

Java 8 streams API

By Carbon Rider in Articles, Java, Java Interview Questions 0 Comment

My experience with querying a collection has always been clumsy. Writing iterative loops, adding nested if conditions and above all the hack of maintaining intermediary collection to store results. On top of that the brutal indicators from SonarQube – cyclomatic complexity. During all this, I felt there is a common pattern for filtering, sorting and there has to be an expressive way to achieve this functionality(someone said more like SQL!!!). With my love towards multiple technologies (Ok I accept I am a polyglot coder), I knew .Net already had an answer to this – LINQ. Simply have a collection and write a query to extract data. Something like below
