Template for Selecting an Open-Source Design System

This document serves as a structured guide for evaluating and selecting an open-source design system that meets ClearCompany's immediate needs and long-term objectives. It includes a detailed checklist of essential components, patterns, and advanced features required to build a scalable, accessible, and future-proof platform. By using this template, engineers and stakeholders can systematically assess potential design systems, ensuring the chosen solution accelerates development, supports enterprise functionality, and aligns with ClearCompany's goals for UpMarket growth.

Introduction

ClearCompany aims to adopt an open-source design system by the third week of January 2025 to accelerate development of the Learning Module (LMS) and support scalability for future UpMarket growth. The selected system must align with ClearCompany’s strategic goals while addressing the challenges of integrating with our legacy Backbone-based stack and enabling a React-first microfrontend architecture. Additionally, the design system must welcome other frameworks (e.g., Angular, Vue, Svelte, Web-components, etc) to accommodate future integrations driven by mergers and acquisitions.

Goals and Objectives

  1. Accelerate Development: Support the rapid delivery of LMS features through modular, reusable components.
  2. Enable Modern Architecture: Integrate React as a primary framework while supporting a microfrontend approach to accommodate both legacy and modern stacks.
  3. Simplify Integration: Leverage hydration and islands approaches to enable legacy Backbone views to coexist with modern frameworks.
  4. Future-Proofing: Adopt a system with a strong focus on maintainability, accessibility, and flexibility to support frameworks expected from mergers and acquisitions.
  5. Enhance Testing and QA: Ensure seamless integration with Cypress for QA automation and provide unit-tested, production-ready components.
