meteor-jest-stubs's Issues

Jest test is unable to import meteor libraries.

Hello,
I am trying to use meteor-jest-stubs with my simple test but I am getting a Unexpected token { error. What am I doing wrong? Would you have a sample demo where we have used meteor-jest-stubs?

StackTrace:

import { check } from 'meteor/check';
           ^
    SyntaxError: Unexpected token {

Update README for new package name

yarn add -D meteor-jest-stubs adds /node_modules/meteor-jest-stubs/lib, but the README still mentions the original package's folder name (jest-meteor-stubs/lib) in the modulePaths stanza in the Usage example.

Should be updated to:

modulePaths: [ '<rootDir>/node_modules/', '<rootDir>/node_modules/meteor-jest-stubs/lib/', ]

Using meteor-jest-stubs to mock meteor, mongo collections.

Do we have an example of how to use meteor-jest-stubs to mock meteor, mongo collections? Somehow I am unable to wrap my head around how to use this.

Fixing "SyntaxError: Unexpected token export"

I had this error:

    Details:

    /Users/ar/meteor-react-typescript-nightwatch/node_modules/meteor-jest-stubs/lib/meteor/react-meteor-data.js:3
    export const withTracker = jest.fn(Op => jest.fn(C => createContainer(Op, C)));
    ^^^^^^

    SyntaxError: Unexpected token export

And could fix it with inlcuding this module again for the transform:

  // An array of regexp pattern strings that are matched against all source file paths, matched files will skip transformation
  transformIgnorePatterns: [
    "<roodDir>/node_modules/meteor-jest-stubs"
  ],

If this is always the case, it should be included in the README.
