changes on dependencies, to fix jest reference error

[alexjorgef]

I have a fresh boilerplate and i'm getting "ReferenceError: self is not defined" running node node_modules/jest/bin/jest.js (yarn jest)

To reproduce:

1. git clone -b RN git@github.com:GeekyAnts/react-native-boilerplate-redux-flow.git
2. cd react-native-boilerplate-redux-flow
3. yarn install
4. yarn jest

Actual result:

FAIL  ............
  ● Test suite failed to run

    ReferenceError: self is not defined

      at node_modules/whatwg-fetch/dist/fetch.umd.js:8:40
      at Object.<anonymous>.support.searchParams (node_modules/whatwg-fetch/dist/fetch.umd.js:2:66)
      at Object.<anonymous> (node_modules/whatwg-fetch/dist/fetch.umd.js:5:2)
      at Object.<anonymous> (node_modules/jest-expo/src/setup.js:7:47)

Expected result:

Tests pass.

Solution:

The problem is because module expo (or jest-expo?) uses isomorphic-fetch, and maybe this boilerplate was created by expo init wich uses a older version of whatwg-fetch.

A workaround is to add whatwg-fetch version 2.0.4 to our package.json

rm -rf node_modules
npm i whatwg-fetch@2.0.4 --save
npm install

Versions

• npm: 3.5.2
• yarn: 1.10.1
