Apollo-link: Missing typings

[j3ddesign]

Expected Behavior
Successful build when running tsc

Actual Behavior
tsc throws the following error:

node_modules/apollo-link-http-common/lib/index.d.ts(3,15): error TS2304: Cannot find name 'Response'.
node_modules/apollo-link-http-common/lib/index.d.ts(8,15): error TS2304: Cannot find name 'Response'.
node_modules/apollo-link-http-common/lib/index.d.ts(37,13): error TS2304: Cannot find name 'GlobalFetch'.
node_modules/apollo-link-http-common/lib/index.d.ts(53,81): error TS2304: Cannot find name 'Response'.
node_modules/apollo-link-http-common/lib/index.d.ts(54,54): error TS2304: Cannot find name 'RequestInfo'.
node_modules/apollo-link-http-common/lib/index.d.ts(54,74): error TS2304: Cannot find name 'RequestInit'.
node_modules/apollo-link-http-common/lib/index.d.ts(54,98): error TS2304: Cannot find name 'Response'.

A _simple_ reproduction
src/index.ts

import 'isomorphic-unfetch';
import { ApolloClient } from 'apollo-client';
import { createHttpLink } from 'apollo-link-http';
import { InMemoryCache } from 'apollo-cache-inmemory';

export const apolloClient = new ApolloClient({
  link: createHttpLink({
    uri: process.env.API_ENDPOINT
  }),
  cache: new InMemoryCache()
});

@j3ddesign Thank you for opening the issue! Take a look at this repo, specifically this commit. It adds dom to the lib, which contains those types. Or you can set your compile option's target to es5 or es6, which will also include those dom as well. How can we help make this more clear? Is there a section in the docs that you would like to see?

[j3ddesign]

Ah interesting. I'm using this in a node project so hadn't added dom to my tsconfig.
In regards to making it more clear, It may help to have it mentioned in the Installation paragraph at https://www.apollographql.com/docs/link/#installation
That's the first page I went to when attempting to troubleshoot this :+1:

Thanks for a great package, It's been a huge help in getting things done quickly :)

Having es5 or es6 as compiler's target won't fix the issue (plus, @j3ddesign did have es6 as target to begin with). Adding dom to lib, though, did fix it.
