I recently started building a small project with TypeScript. It is a small application that runs some workflows based on received Webhook calls. This means that it exposes an Express app to handle these requests.
Currently I have an npm script that builds this project and transpiles it into JavaScript which can be then interpreted by Node.js. (The script runs: tsc --build --clean)
My question is, since this is not meant to be a library/package that will be published on NPM, is there any reason to transpile the project at all since I can just run it with ts-node?
I've been looking around for some information regarding this but couldn't find anything.
Are there any security, performance or any other implications when running the project directly with ts-node in a production environment instead of building it and running it with node?
It depends on the size of your project. Most people transpile because it improves performance, consumes less system resources and provides more stability.
But in a small project this won't make much difference, so using ts-node may be sufficient.
