Past few weeks, I was exploring an alternative platform to share my knowledge with you. I wanted to organize my content in form of Tutorial. I was practicing my communication and presentation skills to work on an interesting concept. Given the pH factor in my blood doesn’t let me settle at one place, I was in search of exploring options to improve my blog content. I confess, sometimes the habit impacts my blog adversely – My Posts gets delayed for longer duration. But this time, I could able to materialize my experiment. I felt accompanying my blog with visual elements and making it more interactive will add value to what I really want to convey. I started my own YouTube channel – Carbonrider. Though I am yet to churn out exhaustive output, let me share few glimpse of my experiences till now.
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.
In the previous article, we created backend system using AWS Lambda, DynamoDB and API Gateway. Unlike the traditional way of hosting code on an application server, we leveraged AWS serverless technologies to host and deploy APIs. In this article, we will develop frontend code, deploy it using S3 static website hosting and finally access the APIs.
Amazon S3 is one of the industry’s leading solution for storing data. It comes bundled with lot of features to meet various requirements for building enterprise grade applications. You can easily host a static website on S3 without worrying about scaling requirements. Store contents securely and enable access to only intended audiences with click-n-configure interface. With user intuitive interface, you can manage your storage efficiently. While preparing for the AWS certification, I came across various S3 features which really outshine other Storage options available in market. I have crafted few questions which will validate your understanding about Amazon S3. Good luck!!!
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.
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. It is a common practice of having multiple style declarations spread across CSS files. 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.
Authentication is often a time-consuming task. Developing a service, using active directory, creating database tables to hold information and most importantly securing credentials all of this soon becomes a very complex process. Besides that, it is very vital to securely exchange the information and validate tokens to ensure user session is valid for the duration of a transaction. But this entire process can be simplified with market-ready solutions like Okta.
PDF form is a great option to distribute and accept data from users. PDF form is similar to a Paper form but with lot more convenience. Apache PDFBox provides low-level APIs to create PDF forms with a rich set of controls and to specify rich formatting options. In the previous article, we explored creating custom pages and adding feature-rich content to a PDF, in this article we will create a PDF form.
In this article, we will look at some of the features offered by Apache PDFBox. In the real world, documents created using PDF libraries may require an additional feature of setting custom page size. Fortunately, PDFBox comes with API to specify page size as per standard units referred in a day to day business. The page sizes are A0, A1, …, A6, LEGAL, and LETTER.
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
