Automatically compile TypeScript files on file save

I'm looking to move a vanilla node.js project to TypeScript and I'm curious about how to restart my server with the latest changes without needing to run tsc from the command line each time I make a change.

I see from this answer two options: ts-node and tsc --watch

Can someone provide a little color on the difference between these two options? I understand they accomplish the same goal, but how are they different and in which situation should I use one over the other?

Just type this in the terminal (In my case it's VS Code with Live Server Installed) --> tsc (Your Typescript File Name).ts --watch

tsc --watch (or tsc -w; same thing).

When your run that command, it will compile .ts files to .js when the .ts files are changed (via saving).

You can add this script

"name_for_your_script" : "tsc <ts file name> --outFile <js file name> -w",

to your package.json file in scripts part and type this code

npm run name_for_your_script

into your terminal. this will automatically compile your ts codes when you save it
