This answer relates to modern setups (TypeScript 2.x, Webpack > 2.x)

You don't need to install @types/node (which is all of Node.js types and is irrelevant for front-end code, actually complicating things such as setTimout different return values, etc..

You do need to install @types/webpack-env

npm i -D @types/webpack-env

which gives the runtime signatures that Webpack has (including require, require.ensure, etc.)

Also make sure that your tsconfig.json file has no set 'types' array -> which will make it pickup all type definitions in your node_modules/@types folder.

If you want to restrict search of types you can set the typeRoot property to node_modules/@types.
