​
Overview

Traza is a modern web application built with a robust tech stack centered around Next.js and Firebase. The application follows a client-server architecture with serverless components, emphasizing scalability, maintainability, and developer experience.

​
Key Technologies

  • Frontend Framework: Next.js 14 with React 18
  • Authentication & Database: Firebase
  • Styling: Tailwind CSS with Radix UI components
  • State Management: React Query (TanStack Query)
  • Form Handling: React Hook Form with Zod validation
  • Testing: Jest with React Testing Library
  • Type Safety: TypeScript

​
Infrastructure

The application infrastructure is built on a modern cloud-native stack:

​
Firebase Services

  • Authentication: User management and authentication flows
  • Cloud Functions: Serverless backend functionality
  • Firestore: NoSQL database for application data
  • Firebase Admin SDK: Secure server-side Firebase operations

​
Deployment & Hosting

  • Vercel: Primary hosting platform for the Next.js application
  • Firebase Hosting: Secondary hosting for specific components
  • Environment Management: Separate development and production environments

​
Development Infrastructure

  • CI/CD: GitHub Actions for automated testing and deployment
  • Code Quality: ESLint and Prettier for code formatting
  • Type Checking: TypeScript for static type checking
  • Package Management: npm with strict versioning

​
Architecture
