In the bustling city of Chennai, India, amidst the vibrant financial landscape, two brilliant software engineers, Durai Kasinathan and Amar Samant, embarked on a remarkable journey to bring harmony to the world of bank reconciliation. Their vision was to create a sophisticated Bank Reconciliation Application that would conduct a symphony of financial balance by harmonizing four essential microservices, each dedicated to a specific business domain.

The Visionaries: Durai Kasinathan and Amar Samant

Durai Kasinathan and Amar Samant, close friends and fellow software engineers, shared a passion for unravelling complexities and creating efficient solutions. Inspired by Chennai’s rich cultural heritage and the rhythmic beats of Carnatic music, they named their masterpiece “The Symphony of ViewModel Composition.”

The Harmonious Ensemble: Four Reconciliation Microservices

1. Regulatory Raga (Microservice-1): Conducting regulatory compliance, ensuring that the financial transactions dance in accordance with the laws and guidelines.
2. Lending Melody (Microservice-2): Orchestrating the world of loans and debt reconciliation, where financial chords are played with finesse.
3. Operational Sangeet (Microservice-3): Maintaining the operational rhythm of the financial institution, ensuring seamless workflows.
4. Market Rhythm (Microservice-4): Composing the symphony of market insights, guiding investment decisions with melodious analytics.

The Crescendo of ViewModel Composition

Driven by their vision, Durai and Amar delved into the art of ViewModel Composition. They divided the complex bank reconciliation process into smaller, harmonious parts represented by distinct ViewModels for each microservice.

The Ensemble Comes Alive: The Bank Reconciliation Application

As the requests flowed into the Reconciliation Application, the Catalog Handler skillfully matched each one to the appropriate microservice. The Composition Gateway conducted the ViewModel Composition, orchestrating a grand symphony of financial reconciliation.

A Resounding Success: Financial Harmony in Chennai

The Symphony of Financial Reconciliation became a resounding success, bringing efficiency and balance to the financial landscape of Chennai. Durai Kasinathan and Amar Samant’s vision of harmonizing diverse microservices through ViewModel Composition became the beacon for financial institutions across the city.

In the heart of Chennai, the Symphony of Financial Reconciliation continues to resonate, uniting the diverse business domains in a mesmerizing financial symphony, thanks to the brilliance of Durai Kasinathan and Amar Samant.

And thus, the legacy of the Symphony of Financial Reconciliation lives on, a timeless tale of innovation and collaboration in the ever-evolving world of finance.

Please note that for the sake of storytelling and to maintain a relatable context, I have used the names of my best friends as characters: “Durai Kasinathan” and “Amar Samant,” who represent the brilliant software engineers in my narrative.

I am Shanoj, a passionate software architect hailing from the enchanting land of Kerala, India. In this article, I am thrilled to take you on a captivating journey of discovery and innovation as I explore the fascinating world of micro frontends. Join me as I unravel the transformation of our software development approach, much like the serene backwaters of Kerala flowing into uncharted territories.

The Monolithic Conundrum:

As I stood amidst the breathtaking scenery of Kerala, I couldn’t help but notice the striking similarity to our software development challenges. Our team was working on a massive monolithic frontend application that mirrored the tangled maze of the region’s lush forests. Maintenance was cumbersome, and collaboration among teams seemed like a distant dream.

Embracing Microservices in the Backends:

Inspiration struck as I witnessed the seamless harmony of Kerala’s backwaters. Microservices were transforming the backend development landscape, offering modular and autonomous solutions. I couldn’t help but wonder, why not apply the same principles to our front-end development?

Discovering Micro Frontends:

Eager to explore this new frontier, I dived into the realm of micro frontends, akin to an explorer charting uncharted waters. It was then that I stumbled upon the enchanting magic of Webpack’s Module Federation. Like the spices that give Kerala cuisine its unique flavor, Webpack added a delightful twist to our frontend architecture.

Designing the Shell Application:

Just as Kerala’s traditional houseboats, locally known as “Kettuvallams,” navigate through the backwaters, we set out to build our shell application. This application would act as the captain, orchestrating and composing the smaller modules or micro frontends.

Setting Sail with Micro Frontends:

Each micro frontend was a manifestation of a unique feature, much like the colourful Kathakali dance masks of Kerala. With Angular Architect’s Web Module Federation, we effortlessly exposed and consumed these micro frontends, each residing on its own independent server.

Dynamic Loading in Full Swing:

The vibrant rhythm of Kerala’s snake boat races inspired us to optimize our application’s performance with dynamic loading. Fetching micro frontends only when needed reduced the initial load time, creating a faster and more delightful user experience.

Scaling New Heights:

Our micro frontend architecture breathed new life into our development process, much like the refreshing monsoon rains of Kerala. This modular approach empowered teams to work independently, scale specific features as required, and deploy with unwavering confidence.

As the sun sets over the horizon of Kerala, my journey with micro frontends comes to a close, leaving behind a legacy of innovation and transformation. Like the ever-evolving culture of Kerala, our software journey will continue to progress, embracing the wonders of micro frontends and unlocking new possibilities.

So, dear readers, as you traverse the lush greenery of Kerala in your thoughts, take a moment to contemplate how micro frontends can revolutionize your own software development voyage. Embrace the change, and together, let’s navigate the boundless waters of innovation and growth!
