[ECWireless]

Summary

• Adds pre-commit and pre-push husky checks
• resolves all lint errors

AI Summary

This pull request introduces a series of type safety improvements, dependency updates, and code cleanups across several components, primarily focused on transaction handling, table rendering, and contract interactions. The most significant changes include stricter type usage for contract amounts, migration from ethers to viem for utility functions, improved type definitions for tables, and enhanced robustness in transaction dialogs.

Type Safety and Contract Interaction Improvements

• Updated all contract interaction components (Approve, DelegatingView, DelegatingWidget/Delegate, Undelegate) to use BigInt for amounts instead of plain numbers or strings, ensuring better type safety and consistency with blockchain data types. [1] [2] [3]
• Migrated parseEther imports from ethers/lib/utils to viem in relevant components, aligning with the preferred library for contract utilities. [1] [2]

Table and List Rendering Enhancements

• Refactored table components (Table, PerformanceList, TransactionsList) to use explicit generic types and improved type definitions from react-table, reducing reliance on any and improving type safety for columns and data. [1] [2] [3] [4] [5]
• Updated table header and cell rendering logic to use more accurate type casting and property access, preventing runtime errors and improving maintainability. [1] [2] [3] [4] [5]

Transaction Dialog Robustness

• Improved the TxConfirmedDialog to handle missing or undefined transaction input data gracefully, preventing crashes and ensuring correct messaging for bond, unbond, and rebond events. [1] [2] [3] [4] [5] [6]

Code Quality and Consistency

• Added pre-commit and pre-push hooks for formatting, linting, and type checking to enforce code quality standards. (.husky/pre-commit, .husky/pre-push) [1] [2]
• Minor cleanups and import reordering for consistency and readability in several components. [1] [2]

History and Performance List Optimizations

• Refactored event merging and sorting logic in HistoryView and PerformanceList for more concise and type-safe operations, improving performance and reliability. [1] [2] [3] [4] [5] [6]

Pull request overview

This pull request introduces husky-based Git hooks for automated code quality enforcement and systematically improves type safety across the codebase by replacing any types with explicit TypeScript definitions. The changes primarily focus on transaction handling, table rendering, and contract interactions while migrating some utility functions from ethers.js to viem.

Key Changes:

• Added pre-commit hooks (format check, lint) and pre-push hooks (type check) using husky v9.1.7
• Replaced any types with explicit type definitions in transaction dialogs, tables, state management, and GraphQL query results
• Migrated parseEther utility from ethers.js to viem in delegation components (partial migration)

Nice, I like the updated types.
