Ntua SaaS 10 Monorepo

Issues and PR's are not visible

This project is an event-driven architecture-based application that converts CSV data into interactive charts and to their png|svg|pdf|html formats.

It uses NX as it's build system and its almost 100% based on TypeScript.

Technologies Used

• Nx: A next generation build system with first class monorepo support and powerful integrations.

• Nest.js: A framework for building scalable and maintainable server-side applications using TypeScript.

• React: A JavaScript library for building user interfaces.

• Firebase: A comprehensive suite of cloud-based tools and services provided by Google, including Firestore for NoSQL database, Firebase Cloud Functions for serverless functions, and Firebase Hosting for web app deployment.

• Docker: A containerization platform that allows packaging applications with their dependencies into standardized units.

• Cloud Run: A serverless compute platform provided by Google Cloud for deploying containerized applications.

• MongoDB: A popular NoSQL database used for the resource-related microservice.

Project Concept

The goal of this project is to provide a user-friendly web application that enables users to upload CSV files and convert the data into interactive charts. The application follows an event-driven architecture, allowing for loose coupling and scalability.

The project is organized as a monorepo using Nx, which provides a powerful development environment for managing multiple related projects. It includes the following components:

• Web App: A React-based web application that provides the user interface for uploading CSV files, visualizing data, and generating charts.

• Nest.js Backend Services: Backend services built with Nest.js, responsible for handling file uploads, data processing, and chart generation. These services follow an event-driven architecture, enabling them to communicate with each other through events.

• Firebase Functions: Cloud Functions are used for serverless execution of backend logic, such as file processing and chart generation. They integrate with Firebase services like Firestore and Cloud Storage.

• Shared: A shared package that contains shared code and utilities used across different packages within the monorepo.

• Web Lib: A shared web library containing smart and dumb UI components, hooks, i18n and other common env configurations to be shared across diffrent React web applications
