Answer 1

For TypeScript 2.x, there are now two steps:

1. Install a package that defines require. For example:

   npm install @types/node --save-dev
   

2. Tell TypeScript to include it globally in tsconfig.json:

   {
       "compilerOptions": {
           "types": ["node"]
       }
   }
   

The second step is only important if you need access to globally available functions such as require. For most packages, you should just use the import package from 'package' pattern. There's no need to include every package in the tsconfig.json types array above.
