solc-helper

Solidity compiler helper utilities. Provides compiler version management, pragma extraction, bytecode hashing, and ABI method signature extraction.

Installation

npm install solc-helper

Quick Start

const { getLatestVersion, extractPragma, bytecodeHash, extractMethodSignatures } = require('solc-helper');

// Get latest Solidity version
console.log(getLatestVersion()); // 0.8.27

// Extract pragma from source code
const source = 'pragma solidity ^0.8.0;\ncontract Test {}';
console.log(extractPragma(source)); // 0.8.0

// Hash a bytecode
const hash = bytecodeHash('0x6080604052348015600f57600080fd5b50...');
console.log(hash);

// Extract method signatures from ABI
const abi = [
  { type: 'function', name: 'transfer', inputs: [{ type: 'address' }, { type: 'uint256' }], stateMutability: 'nonpayable' }
];
console.log(extractMethodSignatures(abi));
// => [{ name: 'transfer', signature: 'transfer(address,uint256)', stateMutability: 'nonpayable' }]

API Reference
