TypeScript Error Fix Progress

Date: June 8, 2026
Session: Fixing Frontend TypeScript Build Errors

Progress Summary

Errors Reduced

  • Starting errors: 1,626
  • After first batch: 919
  • Reduction: 707 errors (43%)

What Was Fixed

1. Import Type vs Import Issues (TS1361)

Fixed 27 files where runtime values (enums, constants, functions) were incorrectly imported using import type.

Items Fixed:

  • MarketStatus - Enum (from @/types/market)
  • MarketOutcome - Enum (from @/types/market)
  • NetworkType - Enum (from @/types/network)
  • RoleType - Enum (from @/types/rbac)
  • Permission - Enum (from @/types/rbac)
  • ExportFormat - Enum (from @/types/export)
  • NETWORK_CONFIGS - Constant object (from @/types/network)
  • DISPUTE_STATUS - Constant object (from @/types/oracle)
  • formatStxAmount - Function (from @/types/liquidity)
  • calculateAPY - Function (from @/types/liquidity)
  • formatBlocksToTime - Function (from @/types/oracle)
  • formatDisputeStatus - Function (from @/types/oracle)
  • getDisputeStatusColor - Function (from @/types/oracle)
  • And more...

Files Fixed:

  • DisputeCard.tsx
  • LiquidityCard.tsx
  • LiquidityStats.tsx
  • MarketCard.tsx
  • NetworkSelector.tsx
  • MarketReview.tsx
  • PoolPositionRow.tsx
  • ResolutionCard.tsx
  • RoleManagementDashboard.tsx
  • NetworkSwitchDialog.tsx
  • rbacConstants.ts
  • LiquidityPage.tsx
  • Plus 15+ more via automated script

2. Missing Type Exports

Added missing exports to src/types/market.ts:

  • MARKET_CATEGORIES - Array of valid categories
  • MARKET_DURATIONS - Duration constants
  • CATEGORY_METADATA - Category metadata with labels/icons
  • CATEGORY_COLORS - Category color mappings
  • CreateMarketFormData - Interface for market creation form
  • MarketCategory - Type for category values

3. Missing Type Properties

Updated Market interface to include:

  • question?: string - Alias for title
  • status?: MarketStatus - Market status enum
  • totalYesStake?: number - Total YES stakes
  • totalNoStake?: number - Total NO stakes

4. Duplicate Identifier

Fixed ExportDialog.tsx - renamed type import to ExportOptionsType to avoid conflict with component name

Automation Created

Scripts:

  1. fix-all-imports.cjs - Automated fixing of import type issues

    • Successfully fixed 27 files
    • Can be run again if more issues arise

  2. fix-import-types.sh - Shell script for batch fixes (backup)

Remaining Issues (919 errors)

Categories:

  1. Property errors (461) - Missing properties on types
  2. Type errors (108) - Type mismatches
  3. Module errors (101) - Missing exports
  4. Argument errors (84) - Wrong argument types
  5. Parameter errors (36) - Implicit any types
  6. Other (129) - Various issues

Top Priority Issues:

1. FraudAlertPanel - Missing Type Properties

  • FraudAlert type missing: message, createdAt, alertId, status
  • SuspiciousActivity type missing: description, status, detectedAt, activityId

Next Steps

Phase 1: Fix Missing Type Properties

  1. Add missing properties to FraudAlert and SuspiciousActivity types
  2. Update ErrorLoggingService to export ErrorLog type
  3. Add missing methods to services

Phase 2: Fix Missing Function Exports

  1. Export validateMarketForm from marketValidation
  2. Export formatBlocksToTime from marketValidation (or import from oracle)
  3. Export suggestQuestionImprovements function

Phase 3: Fix Type Mismatches

  1. Update RefObject types to handle null properly
  2. Fix Portfolio type usage in ExportDialog
  3. Add missing properties to interfaces

Phase 4: Fix Implicit Any Types

  1. Add type annotations to parameters in various files
  2. Fix array indexing issues in MobileGrid

Estimated Time to Complete

  • Phase 1: 2-3 hours
  • Phase 2: 1-2 hours
  • Phase 3: 2-3 hours
  • Phase 4: 1 hour

Total: 6-9 hours to fix all remaining 919 errors
