React + TypeScript + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

• @vitejs/plugin-react uses Babel for Fast Refresh
• @vitejs/plugin-react-swc uses SWC for Fast Refresh

Expanding the ESLint configuration

If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:

• Configure the top-level parserOptions property like this:

export default {
  // other rules...
  parserOptions: {
    ecmaVersion: 'latest',
    sourceType: 'module',
    project: ['./tsconfig.json', './tsconfig.node.json'],
    tsconfigRootDir: __dirname,
  },
}

• Replace plugin:@typescript-eslint/recommended to plugin:@typescript-eslint/recommended-type-checked or plugin:@typescript-eslint/strict-type-checked
• Optionally add plugin:@typescript-eslint/stylistic-type-checked
• Install eslint-plugin-react and add plugin:react/recommended & plugin:react/jsx-runtime to the extends list

🛠️ Upcoming Development

This section outlines the planned enhancements and architectural improvements for the platform.

---

🔧 Core Infrastructure & Services

• ✅ Integrate centralized logger in all services:

  • Evaluator Service
  • Submission Service
  • Socket Service
  • Frontend (via loglevel or similar)

• 🛠️ Create standalone Auth Service:

  • JWT-based authentication
  • Access token + refresh token mechanism
  • Secure route protection

• 🔐 Implement Role-Based Access Control (RBAC):

  • Roles: admin, problem-setter, user
  • Permissions applied both on backend routes and frontend UI controls (tabs, actions)

---

⚙️ Developer Experience Improvements

• 🧩 GraphQL Integration (Apollo Client):

  • Refactor REST endpoints to GraphQL for fine-grained control
  • Use GraphQL queries in problem list and detail pages

• 🧪 Testing:

  • Unit Tests (Jest)
  • Component Tests (React Testing Library / Cypress Component Testing)
  • Backend Integration Tests (Supertest)

🚀 DevOps, Deployment & Load Handling

• ⚙️ CI/CD Pipeline:

  • Set up GitHub Actions or GitLab CI
  • Steps: Lint → Test → Build → Deploy

• 📊 Load Testing with K6:

  • Simulate concurrent user submissions
  • Benchmark evaluator and submission services

• 🔁 Evaluator Queue Load Balancing:

  • Multiple queue instances
  • Round-robin or load-based distribution

• ⭐ Premium Queue Prioritization:

  • Dedicated high-priority queues for premium users
  • Weighted or time-based dequeue logic

🧠 Git Strategy & Release Management

• 🪄 Adopt Git branching workflow:
  • develop: daily active development
  • release: monthly stable version
  • main: production branch
  • Cherry-pick important bug fixes from develop to release
