Svelte Component Visulaizer | VS Code Extension • Utilized Typescript to ensure type uniformity and consistency of the codebase, enhancing code comprehension and readability as well as exercising its strong typing feature to help enable early bug detection, leading to increased efficiency and resource savings.• Employed Svelte for its rapid initial load times, small bundle size, declarative component based architecture, and lack of a virtual DOM to render the visualizer within VS Code webview ensuring a smooth developer experience.• Designed a custom parsing algorithm, taking advantage of Node.js non-blocking I/O model and file system modules to traverse directories and store component data including file names and contents used to generate the component structure displayed with D3.• Integrated Mocha for unit testing with extensive code coverage to mock expected behavior, leveraging its lightweight design and flexibility, seamlessly integrating with Node enabling direct test writing without additional overhead or unnecessary dependencies.• Harnessed Webpack bundling to ensure scalability and faster load times, while seamlessly integrating hot module replacement for instant module updates, enabling quicker iterations, and enhancing the overall developer experience.• Leveraged D3.js specifically for its robust customizable features and compatibility with Svelte, ensuring the extension can dynamically generate component trees in VS Code webview, while maintaining optimal performance and rapid rendering speeds.

• Utilized React for its simplicity and adept state management using useState, while leveraging its component modularization to ensure cohesive and scalable UI, essential for displaying portfolio information and real-time prices within the application. • Implemented MongoDB to monitor and manage individual portfolios and balances, this choice over a relational database was made specifically for schema flexibility, prioritizing MongoDB's flexible document-based model and horizontal scalability.• Employed Express and adopted middleware patterns to design a modular backend system, utilizing its HTTP methods to efficiently fetch external API data for real-time market updates, enhancing the realism and overall user experience.

• Utilized Jest for crafting and executing unit tests, incorporating snapshot testing and parallel testing to ensure bug-free functionalityfor newly added features. • Leveraged Redux and Redux Toolkit to effectively manage the application's state and data flow, enabling robust control andstreamlined data management across the app's lifecycle and development stages.
