How it got here

2022 · Project scaffolding and architecture setup

This period focused on establishing the project's foundational structure, renaming it to 'notionlingo' and upgrading to Next.js 13.3 with a comprehensive set of development tools, including ESLint, Prettier, and Yarn PnP. The work involved creating robust scaffolding templates for components, functions, and hooks, while simultaneously refactoring the application's page structure and API routes to support a clean, modular architecture. Additionally, new API endpoints were introduced to handle user profiles and integrate with Notion, marking the beginning of core feature development.
