Foundry is an opinionated toolkit that centralizes and automates the configuration of code quality tools for JavaScript/TypeScript projects. It bundles and exposes composable ESLint flat configs, Biome configuration, Stylelint configuration, Husky hooks, and lint-staged setup. The CLI (`foundry init`) detects installed frameworks and dependencies (React, Next.js, Jest, etc.), generates tailored config files, and updates package.json scripts. The package primarily serves as a shared, versioned dependency that enforces consistent linting and formatting across multiple projects within an organization. The architecture is a library of configuration objects combined with a thin CLI wrapper, and the code is well-structured, modular, and thoroughly tested.
The Web Tooling Benchmark is a performance measurement suite designed to evaluate JavaScript-related workloads in common web developer tools. It executes benchmarks for tools like Babel, TypeScript, UglifyJS, and others, measuring their throughput in runs per second. The architecture consists of a Node.js CLI interface and a browser-compatible bundle, both driven by a benchmark suite that runs each tool's core functionality on standardized third-party code samples. Key entry points are src/cli.js (for Node.js) and src/bootstrap.js (for browser). The suite reads input files from the third_party directory, processes them via each tool's API, and aggregates results using geometric mean. External dependencies include the benchmarking framework, various JavaScript tools (acorn, babel, typescript, etc.), and utilities for file system virtualization and output formatting.
