tsc - Typescript noEmit use case

Question

What is the use case for noEmit in Typescript? I'm interested because I want to see if I can use this for development where I'll compile and run the compiled code without outputting them onto the file system which would be more efficient.

Edit: Perhaps this would be straight forward: "Can I use noEmit tag in typescript to compile and run the code without outputting them onto the file system? If so, how would I do that?"

Answer 1

It's used when tsc is used only for type checking, not for compilation. That's the case when some other tool (like Webpack, Parcel or Rollup) is responsible for compiling your code.

If you are interested in running your code in an interactive mode, look into ts-node or ts-node-dev.
