React Native with TypeScript: How to set up globals in setup.js?
I'm building a React Native app with TypeScript.
I want to use jest-fetch-mock. In the documentation it says to create setup.js file and add
global.fetch = require("jest-fetch-mock");
in it. I did that. But I get the error:
[ts] Cannot compile namespaces when the '--isolatedModules' flag is provided.
So I googled and found out that I just have to import something to fix this (which is fine, since I need imports for setting NativeModules.ReactLocalization for using localization anyway).
Then I get the error:
[ts] Cannot find name 'global'.
So I googled some more and found this 'fix':
// Change to file to setup.ts and
const globalAny: any = global;
But it throws the same error and now I'm stuck. How can I set a global variable?

Why typescript compiles .js files?
If you have setup.ts file: try to add declare var global: any; before global.fetch = ....
However, I suggest you to use typings for your project:
npm i -D @types/node @types/jest
Then extending global object will look like this:
declare module NodeJS {
interface Global {
fetch: GlobalFetch
}
}
global.fetch = require('jest-fetch-mock');
