How do you run TypeScript files from command line

Question

It's surprising to have such a hard time with this. I'm used to running my code from the command line and it would be really convenient if I could do the same over here.

Does anyone have an idea on how to do this?

Answer 1

You can leave tsc running in watch mode using tsc -w -p . and it will generate .js files for you in a live fashion, so you can run node foo.js like normal

TS Node

There is ts-node : https://github.com/TypeStrong/ts-node that will compile the code on the fly and run it through node 🌹

npx ts-node src/foo.ts
