In our previous blog (Efficient PDF Generation – Part 1), we narrowed down on using SVG rendering as an option to generate PDF reports, mostly due to its efficiency over other methods.In this blog, we will walk you through our use case and explain how we solved some of the challenges using SVG for PDF…
Problem Statement As part of product development, developers frequently encounter the need to provide comprehensive PDF reports. While multiple approaches are available to generate the rich PDF reports required for your product, building an efficient and elegant solution necessitates a certain amount of research. Surprisingly, such a solution has been elusive. This article aims to…
Context Our healthcare client operates wellness clinics in multiple locations and offers a service that assesses and prescribes exercises based on patients’ needs. The service uses a machine that measures muscle strength and sends data to a centralized web app for analysis and reporting. The client learned that the exercise machines that are being used…
Context Selecting an API automation tool has become increasingly difficult over the years. The plethora of tools available makes it very difficult to make a choice that fits the requirements of any project. This analysis represents our research and experience in testing and using some of these tools in our projects at Indexnine. We have…
The problem is well-known to any product development team: Regression tests take too long to execute. Regression testing verifies that software previously developed and tested still performs correctly after it was changed or enhanced. Changes may include software enhancements, patches, configuration changes. In one of our projects, we have over 3500 regression tests. Every release,…

At Indexnine, we have a simple formula when it comes to building products; collaborate, create solutions, build it fast and build it for scale. Indexnine was building software products for over 4 years before I joined, where the design function was also led by our CTO and part-time designer. It was always clear that development…
Shadow DOM Shadow DOM is a web standard that developers use to encapsulate their html code and style components so that no other style components can override their code. It is a critically important piece of the web components story as it ensures that a component will work in any environment even if other CSS…
After having seen an overview of serverless computing with AWS and some tips on configuring Lambda, we will move on in this post, to share some of the challenges that we faced and resolved. The reference application is a real time data processing application that used serverless computing as part of its architecture. A brief…
In the earlier blog post of this series, we had seen a general overview of serverless computing with AWS. In this part, we will look at configuring a Lambda function and follow up with an architecture diagram of an application that performs real time processing of data coming in from multiple sources. Lambda Configuration -…
What is Serverless Computing? Wikipedia defines this as: “Serverless computing is a cloud-computing execution model in which the cloud provider acts as the server, dynamically managing the allocation of machine resources. Pricing is based on the actual amount of resources consumed by an application, rather than on pre-purchased units of capacity.” This does not mean…
Traditionally, web applications were built as a monolithic app, designed to scale within a given server. In order to authenticate valid users, the classic approach was to use a “cookie” or a small object containing user information and store it in a “session” object on the server side. (more about session). In this approach, “state”…
Forms, as we all know, are a vital part of web development. All of us who are familiar with AngularJS will agree with the fact that how easy it is to develop robust scalable from-ends using AngularJS. But it comes with its own problems, one of the biggest being how to deal with big forms.…
Microservices has been a buzzword in software engineering recently. Everyone wants to build their application around Microservices architecture. Before you jump onto the bandwagon, lets do a critical review of Microservices. We will look at the cases where it is appropriate along with advantages and disadvantages. Before we proceed let us look at how to…
Each day, large amounts of data and metrics are collected from real time activity streams, performance metrics, application logs, web activity tracking and much more. Modern scalable applications need a messaging bus that can collect this massive continuous stream of data without sacrificing good performance and scalability. Apache Kafka is built ground up to solve…
While there are numerous advantages of deploying on the cloud, there are no guarantees that the cloud platform services will respond successfully every time. In a cloud environment periodic transient failures should be expected. The approach should be to minimize the impact of such failures on the application execution by anticipating and proactively handling failures.The…
In previous posts, we covered the benefits of moving to the cloud for scale and the design principles of building scalable applications. In this post, we will look at a typical reference architecture for a cloud based scalable application and cloud features that help your application scale.Architecture The below listed figure illustrates a reference architecture…
In the previous post, we covered the benefits of moving to the cloud for scale. In this post, we will look at some best practices to build applications for the cloud.1. Use messaging to decouple components One of the important principles of scalable application design is to implement asynchronous communication between components. To start with…

In today’s world, it is imperative to have a strategy for consumers on smartphones and tablets. The statistics speak for themselves: In 2012, a study found that 22% of web content was being consumed by smartphones and tablets. Two short years later, the figure stands at around 56%. The internet is full of statistics about…
