rscute is an in-memory TypeScript bundler and executor, leveraging `@swc/core` for high-performance AST transformation and compilation. Currently at stable version 1.2.2, it exhibits an active release cadence with frequent updates. Its core functionality involves intercepting Node.js `require` calls, recursively resolving TypeScript and JavaScript dependencies, and evaluating them as a single, flattened bundle entirely within memory. Key differentiators include its transparent runtime execution capabilities for TypeScript files, a dedicated API for in-memory bundling without execution, and automatic symbol mangling to prevent name collisions in the flattened module scope. It supports various entry points, including a CLI, a Node.js `-r` flag hook, and dedicated programmatic APIs for code execution in a sandboxed VM context or for bundling to a string.
