This should be opt-in

Yes, do you suggest adding a new configuration for this feature?

We should avoid loading typescript package as it adds runtime overhead.

I have considered this issue and come up with two alternative solutions:

1. Implement a lightweight tsconfig.json parsing logic that only parses the paths and baseUrl fields to infer the alias.

2. Use a lightweight alternative library (e.g., https://github.com/privatenumber/get-tsconfig) (or implement one ourselves) to parse the complete tsconfig.json configuration, which can not only be used for alias inference but also for other configurations, such as automatically passing it to esbuild's tsconfigRaw (which can resolve Decorators support #309), thereby eliminating the need to duplicate existing content from tsconfig.json in configuration files.

I'd love to hear your feedback! 🤔
