What is the correct way of transpiling?

I am using TypeScript and ts-node to execute my script as follows:

node -r ts-node/register index.ts

This works fine, but the compilation process takes too long so I would like to speed everything up. I noticed, that I might also just transpile the TypeScript file and call the resulting index.js directly.

What exactly are the requirements for this? Do I need to use tsc, ts-node, ts-node-dev or node to make this work?

Any info that makes me able to execute the index.js is appreciated!

Just run `tsc` on the files in the project? – CertainPerformance Feb 07 '21 at 22:24
It still takes too long to start-up – Daniel Stephens Feb 07 '21 at 22:24

Compiling takes some time, but at least that way, you'll be able to compile *once* and be done rather than whenever the script is run - isn't that what you're looking for? – CertainPerformance Feb 07 '21 at 22:25
Debugging already works, but now I would like to get a "production build" where I just execute the "application/script" – Daniel Stephens Feb 07 '21 at 22:26

Yes, compiling the TS to JS with `tsc` can give you a production-level build if that's what you want – CertainPerformance Feb 07 '21 at 22:26
Thanks for the clarification! I just found this after your answer https://stackoverflow.com/questions/51448376/whats-the-difference-between-tsc-typescript-compiler-and-ts-node which might be the cause of my confusion – Daniel Stephens Feb 07 '21 at 22:27
