Migrate from ts-node to tsx

[peter-leonov-ch]

Summary

The long beloved ts-node hasn't been updated in 2 years. It also uses acorn pure JS parser which also tends to be less popular and performant than the Go-based esbuild used in tsx.

Pros:

• actively supported project
• widely used parser / transformer
• snappier experience
• native file-aware watch mode

Cons:

• does not support type checking
