Bun Module Identifier

is-bun-module is a TypeScript utility library designed to programmatically identify and list modules within the Bun runtime environment. It distinguishes between Bun's native core modules (e.g., `bun:test`) and Node.js built-in modules that Bun has implemented (e.g., `fs`, `path`). The library provides functions to check individual module specifiers as well as retrieve comprehensive lists of all supported modules, optionally filtered by a specific Bun version string (e.g., '1.0.0' or 'latest'). As of version 2.0.0, the package is actively maintained with regular updates to reflect changes in Bun's module landscape, and it ships with full TypeScript type definitions for robust development.
