How to setup VSCode to show typescript error inline

Question

I\'m trying to migrate an ES6 project to typescript. This is my first attempt at writing a typescript module in NodeJS.

It seems to work better in Angular-CLI so far.

Answer 1

Even without having installed TypeScript locally or globally, the following setup provides inline errors.

C:/temp
  index.ts
  tsconfig.json

index.ts

let x: number;
x = "foo";

tsconfig.json

{ }

Here is a screenshot that shows the inline error in x.

Please try that setup and report back on what happens.
