solc-js

JavaScript bindings for the Solidity compiler, wrapping Emscripten-compiled binaries from solc-bin. The current stable version is 0.8.28 (as of 2025), with a release cadence following Solidity releases (monthly). Key differentiators: it is the official JS wrapper for the Solidity compiler, supports standard JSON I/O (compileStandard/compileStandardWrapper), legacy compile() API, and import callbacks for resolving dependencies. Alternative is solc-typed by TypeChain but this is the canonical package for compiling Solidity in Node.js and browser environments.
