$ show microsoft/vscode-ripgrep
A monorepo that publishes npm packages bundling precompiled ripgrep (rg) binaries for 12 platform/architecture combinations. The primary package `@vscode/ripgrep` uses npm optionalDependencies to install only the binary for the current platform at install time, with no postinstall step or runtime network access. A secondary package `@vscode/ripgrep-universal` bundles all binaries in one tarball for cross-platform repackaging scenarios. Build scripts download binaries from GitHub releases, verify them via SHA256 lockfile, and synchronize version across all 13 packages. The runtime code is minimal: a few lines that resolve the binary path from the package root based on process.platform and process.arch. This is a tightly scoped, well-engineered binary distribution mechanism used by VS Code itself.
The LLM identified 2 files worth highlighting for reuse:
Exports `binPathFor({ os, arch })` and `rgPath` constant. Constructs binary path from package root using `import.meta.url` and `path.dirname`, accounts for Windows `.exe` suffix, and respects the `npm_config_arch` environment variable. Self-contained, no internal imports beyond Node.js built-ins, and could be extracted as a generic helper for any project that ships platform-specific binaries under a `bin/<os>-<arch>/` directory.
Uses `createRequire` to resolve the platform-specific binary from an optional dependency (`@vscode/ripgrep-${platform}-${arch}`). Provides a descriptive error if the optional package is missing. Demonstrates a clean pattern for leveraging npm's optionalDependencies mechanism to deliver native binaries without postinstall scripts or runtime downloads. The logic is minimal and focused, and the pattern is applicable to any native module distribution strategy in Node.js.
