Anson demonstrates how to set up a TypeScript project with Express, annotate arguments, and write tests using Jest.

*DISCLAIMER* This is NOT a full in depth tutorial on Express JS. It is only designed to walk you through the setup process of installing TypeScript, getting it up and running with Express, and show you examples of type annotating arguments. I have also added other examples with Unit Testing & Integration testing with Jest and ts-jest. I highly recommend you use this as a way to learn how to setup a TypeScript project for Express, and then slowly migrate over your code. Many of the concepts covered in my Express JS Full Course can easily be translated over once you get the idea of what to type annotate.

On “JS TO TS ”

Did you read the typescript handbook? If not, that's where you're supposed to start. TS Handbook Using TS with Node/Express shouldn't be that different from what you learned from the handbook. Express has types available to install in a project. Don't have a recommended blog, but I used to watch Anson in Youtube. Here's the Express + TS vid.
