How to compile typescript using npm command?

Question

Well, I just wanted to know if there is any command that will directly compile typescript code and get the result. Right now, what am I doing, every time I make changes to the file, I have to re-run the inorder command to compile it.

npm start

This will launch the browser, and then I have to stop the execution using ctrl + c, and then I have to start the file using the npm command

node file_name

to see the result.

So I want to know if there is any npm command that will compile the .ts file and see the changes I made in the file when I run the file with

node file_name
