Importing node and express with typings in TypeScript

Question

I am trying to set up a TypeScript express/node application in Visual Studio Code following the Microsoft guide but changing it to use TypeScript however when it comes to instal

Answer 1

As of the release of TypeScript 2.0 last month, the recommended tool for installing typings is our trusty old friend npm instead of typings or tsd.

npm install @types/node --save

With npm, there's no need to worry about "global" or "ambient" installations anymore.

You also don't need to worry about adding tags to the top of your source files anymore; just drop the following property into your compilerOptions in tsconfig.json, and the TypeScript compiler will automatically find the npm typings you've installed:

"typeRoots": [ "node_modules/@types" ]

Here's a blog post that explains the change in some more detail: https://blogs.msdn.microsoft.com/typescript/2016/06/15/the-future-of-declaration-files/
