Auth Flow

Types (auth/auth.types.ts)

User { id, email, role, name? }
AuthState { user, accessToken, isAuthed }
AuthContextValue = AuthState & { login, logout, applyOAuthTokens }

AuthContext (auth/AuthContext.tsx)

• Access token: in-memory only (NEVER in localStorage)
• Refresh token: in localStorage for persistence
• Bootstrap: On mount → silent refresh via /auth/refresh → decode JWT for User
• Login: POST /auth/login → stores both tokens
• OAuth: applyOAuthTokens(at, rt) → decode JWT → set user
• Logout: POST /auth/logout → clears both tokens
• Session expiry: Listens for auth:expired custom event

Token Refresh (lib/api.ts)

• Axios response interceptor on 401 → attempts refresh using stored RT
• Queues concurrent failing requests during refresh (only one refresh runs at a time)
• Dispatches auth:expired custom event when refresh fails
• Also handles 429 → dispatches api:rate-limited custom event

Route Guards

• RequireAuth: Redirects to /login if !isAuthed, preserves intended URL in location.state
• RequireRole: Checks user.role against allow[] array, redirects to /403

Roles

ADMIN | TEAM_MANAGER | REFEREE | SUPERVISOR | PUBLIC

---

Shell / Layout

AppShell (shell/AppShell.tsx) — Protected

• Ant Design Layout with collapsible Sider + Header + Content
• Sidebar: Dynamic menu filtered by user role (from menu.ts)
• Header: Global search (debounced 300ms autocomplete via /search), dark mode toggle, language toggle (VI/EN), user dropdown (profile, change password, logout)
• <Outlet /> renders child routes

PublicLayout (shell/PublicLayout.tsx)

• Gradient header with V-League branding
• Horizontal menu: Standings, Schedule, Results
• Login button
• Footer with copyright

ThemeContext (shell/ThemeContext.tsx)

• Light/dark mode toggle via React Context
• Persisted to localStorage key vleague-theme
• Returns theme.darkAlgorithm or theme.defaultAlgorithm for Ant Design

Menu (shell/menu.ts) — 12 items

Menu Item	Roles
Dashboard, Standings, Head-to-Head, Reports	All
Seasons, Stadiums, Regulations, Users	ADMIN only
Teams, Players	ADMIN, TEAM_MANAGER, SUPERVISOR, PUBLIC
Schedule, Matches	ADMIN, TEAM_MANAGER, REFEREE, SUPERVISOR, PUBLIC

---

i18n Setup

Configuration (lib/i18n.ts)

• Languages: Vietnamese (vi, fallback) and English (en)
• Detection: localStorage key vleague-lang → browser navigator
• Plugin: i18next-browser-languagedetector

Translation Files

• locales/vi.ts — ~1,244 lines, comprehensive Vietnamese catalog
• locales/en.ts — ~1,207 lines, English mirror

Namespace Convention

dashboard.*, matches.*, teams.*, players.*, seasons.*, schedule.*, standings.*, stadiums.*, users.*, profile.*, sessions.*, regulations.*, reports.*, headToHead.*, login.*, register.*, forgotPassword.*, resetPassword.*, changePassword.*, verifyEmail.*, teamDetail.*, playerDetail.*, stadiumDetail.*, forbidden.*, oauth.*

TypeScript Types

Domain Types (co-located in service files)

Type	Key Fields
Team	id, name, shortName?, logoUrl?, city?, status, stadiumId?, stadium?
TeamDetail	extends Team + teamPlayers[], homeMatches[], awayMatches[], standings[]
Player	id, fullName, dob, nationality, position, playerType, birthPlace?, heightCm?, weightKg?, teamPlayers?
Stadium	id, name, address?, city, capacity?
StadiumDetail	extends Stadium + teams[], matches[]
Season	id, name, year, status, startDate?, endDate?
SeasonTeam	id, seasonId, teamId, status, registeredAt, approvedAt, team
Match	id, roundNo, leg, seasonId?, homeTeamId, awayTeamId, homeTeam?, awayTeam?, homeScore?, awayScore?, stadiumId?, stadium?, kickoffAt?, status, events?
MatchEvent	id, minute, type, goalType?, playerId?, player?, teamId?, team?, relatedPlayerId?, relatedPlayer?, note?
TeamStanding	position, teamId, teamName, played, won, drawn, lost, goalsFor, goalsAgainst, goalDifference, points
TopScorer	position, playerId, playerName, teamId, teamName, goals
CardStat	position, playerId, playerName, teamId, teamName, yellowCards, redCards, totalCards
TeamStat	extends standings + cleanSheets, yellowCards, redCards
HeadToHeadResult	team comparison data
PlayerStats	goals, assists, cards, goals-by-round
Regulation	id, seasonId, key, value, valueType
User	id, email, name?, role, emailVerified, avatarUrl?, googleId?, facebookId?
Session	id, deviceName, userAgent, ipAddress, lastUsedAt, createdAt, expiresAt
PaginatedResponse<T>	data[], total, page, limit, totalPages

Enums (string unions)

• Position: 'GK' | 'DF' | 'MF' | 'FW'
• PlayerType: 'DOMESTIC' | 'FOREIGN'
• MatchStatus: 'DRAFT' | 'PUBLISHED' | 'LOCKED' | 'FINISHED' | 'POSTPONED'
• SeasonStatus: 'UPCOMING' | 'IN_PROGRESS' | 'COMPLETED'
• SeasonTeamStatus: 'REGISTERED' | 'APPROVED' | 'REJECTED' | 'WITHDRAWN'
• EventType: 'GOAL' | 'OWN_GOAL' | 'PENALTY' | 'PENALTY_MISS' | 'YELLOW_CARD' | 'RED_CARD' | 'SUBSTITUTION'
• UserRole: 'ADMIN' | 'TEAM_MANAGER' | 'REFEREE' | 'SUPERVISOR' | 'PUBLIC'
• ThemeMode: 'light' | 'dark'

---

State Management Patterns

No Redux/Zustand — pure React patterns:

• AuthContext: Global auth state (React Context + useState)
• ThemeContext: Dark/light mode (React Context + useState)
• Per-page local state: useState + useEffect for data fetching
• useCallback: Memoized fetch functions
• useMemo: Derived data (filtered lists, role checks, menu items)
• Promise.allSettled: Parallel API calls on Dashboard and Reports
• useRef: Debounce timers (global search), prevent duplicate processing (OAuth)
• Custom events: auth:expired, api:rate-limited for cross-cutting concerns

---

Environment Variables

Variable	Usage
VITE_API_BASE_URL	Backend API URL (default: http://localhost:8080/api)
VITE_SENTRY_DSN	Sentry DSN (optional, no-op when unset)
VITE_APP_VERSION	Sentry release tag

---

Utility Constants (utils/constants.ts)

Constant	Content
STATUS_MAP	Match statuses → { label, color } (admin labels)
PUBLIC_STATUS_MAP	Match statuses → user-friendly labels
EVENT_TYPE_MAP	Event types → { label, color, icon }
POSITION_MAP	GK/DF/MF/FW → { label, color }
CAN_EDIT_ROLES	['ADMIN', 'REFEREE']

---

Notable Patterns

1. Lazy loading: All protected pages + layouts are React.lazy(). Auth pages eager for fast first paint
2. Dual HTTP clients: lib/api.ts (Axios, primary) + services/http.ts (fetch, legacy/unused)
3. Token refresh queue: Concurrent 401s queued; only one refresh runs at a time
4. PDF export: Dynamic import('jspdf') to avoid bundling unless needed
5. CSV export: ExportButton component + csvExport.ts utility (UTF-8 BOM for Excel)
6. Player CSV import: apiImportPlayersCsv sends FormData; downloadPlayerCsvTemplate() for template
7. Match status FSM: DRAFT → PUBLISHED → LOCKED → FINISHED (with POSTPONED side-paths)
8. Standings highlighting: AFC Champions League zone (green) + relegation zone (red) via CSS classes
9. Session management: View active sessions, revoke individual/all
10. OAuth flow: Server redirect → /auth/oauth-callback?accessToken=&refreshToken=
11. Global search: Debounced 300ms autocomplete in AppShell header
12. Recharts: Bar charts (goals by round, team points), Pie chart (goal distribution)
13. Sentry: Browser tracing + session replay (100% dev / 20% prod)

---

Testing Conventions

• 15 page test suites, 13 service test suites, 2 auth test suites
• Page tests: src/pages/__tests__/*.test.tsx
• Service tests: src/services/__tests__/*.test.ts
• Auth tests: src/auth/AuthContext.test.tsx, RequireAuth.test.tsx
• Always use vi.hoisted() for mock variables inside vi.mock()
• Mock ../../lib/api for service tests
• Mock individual service files + react-router-dom for page tests
• Use getAllByText() instead of getByText() for Ant Design duplicate text
• Import from __tests__/ goes up one level: ../ComponentName

Polyfills (vitest.setup.ts)

• @testing-library/jest-dom/vitest for custom matchers
• i18n initialized with Vietnamese, no language detector
• ResizeObserver polyfill (Ant Design Tabs/Collapse)
• window.matchMedia polyfill (Ant Design responsive)
