TypeScript Dual Module Builder

ts-dual-module is a command-line tool designed to simplify the creation of dual-module (ESM + CommonJS) packages using TypeScript. It targets projects that define `"type": "module"` in their `package.json` and automatically builds both module formats from TypeScript sources, typically located in a `./src` directory and outputting to `./dist`. The tool handles the complexities of `package.json` `exports` and `typesVersions` fields to ensure correct module resolution and type declarations for both environments, specifically addressing CommonJS subpath export issues where TypeScript's default `moduleResolution` might fall short. The current stable version is 0.6.3, indicating it's actively maintained but still in a pre-1.0 development phase, which implies a focus on adding features and refining functionality, potentially with breaking changes between minor versions. Its key differentiator is the automation of dual-module bundling and `package.json` configuration, saving developers from complex manual setup or reliance on multiple build steps with different TypeScript configurations.
