solc-js

JavaScript bindings for the Solidity compiler, enabling Solidity smart contract compilation directly in Node.js or the browser via Emscripten. This version 0.8.1 is a fixed release of the official npm package by the Ethereum Foundation. It provides both a high-level API (uniform `compile` method using Standard JSON I/O) and a low-level API exposing compiler internals. Key differentiators: it wraps the native Solidity compiler, supports imports via callbacks, and the command-line interface (`solcjs`) is not compatible with the native `solc` binary. Major breaking changes include the removal of the old callback-based API since v0.6.0. Regular releases track Solidity compiler versions.
