How to get Node.JS to process TypeScript directly without transpiling like it already does with ES6?

Answer 2

This is much easier to do than you might think. You execute in the console, for example, the following:
And write something like this code in app.ts:

import * as express from 'express';

const app: express.Aplication = new Express();
app.get('/hello', helloMessage);

function helloMessage(req: express.Request, res: express.Response) {
   console.log("Hello!");
}

app.listen(8000)

Well, then just compile through tsc.
See if there is @types/moduleName for the desired module here . If this is not available, then write manually (I did not do this myself, but others say that it is quick and easy).
For reference, you can see this article , but there is a very ancient way of working with typescript described. You don't have to do it

Answer 3

No way. TypeScript is not an official specification.
