having trouble locating d.ts for fetch!

[ORESoftware]

Hi there!

I followed the link in the readme, and I can't figure out how to get this to work. I assume we have to install some @types/fetch to get things to work, but I am not seeing on how to actually get the typings! I am up-to-date on everything and still TS does not recognized fetch the browser.

You don't need to install anything, but you do need to reference the d.ts somehow.

Here's a few Stack Overflow posts on referencing:

Then just download the d.ts into your project:

thanks! I was stuck

there must be a way to do this with tsconfig.json, but having trouble finding that in the answers, if/when I find it, will post it here

maybe this? http://stackoverflow.com/a/40861142/1223975

and: https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/whatwg-fetch/tsconfig.json

I actually think the right way to this nowadays is simply:

npm install -D @types/whatwg-fetch

so I was not far off with ....

npm install -D @types/fetch

then in your tsconfig.json file you add:

{
  "compilerOptions": {
    "baseUrl": "public",
    "paths": {
      "@hot-reload-handler": [ "public/js/hot-reload-handler"],
      "@hot-reloader": [ "public/js/hot-reloader"]
    },
    "types": [

      "react",
      "react-dom",
      "redux",
      "react-redux",
      "redux-thunk",
      "async",
      "requirejs",
      "socket.io-client",
      "immutable",
      "uuid",
      "whatwg-fetch"   // <<<<< add this line here
    ],
 ...
}

type FetchParams = Parameters<typeof window.fetch>;
type FetchInput = FetchParams[0];
type FetchInit = FetchParams[1];
