@RobH123 It looks like this is ready to go except for version. Published as 0.8.15-alpha.1 for testing.

@RobH123 it looks like you should probably add ./dist/__tests__/ to .npmignore. Looks like that is the source of extra files in your npm modules.

@RobH123 Also you can cut test time in half by changing the jest configuration section in package.json to be:

  "jest": {
    "collectCoverageFrom": [
      "src/core/**.{js,jsx,ts}",
      "!**/node_modules/**",
      "!**/vendor/**"
    ],
    "modulePathIgnorePatterns": ["<rootDir>/dist/"]
  }

Unfortunately it is copying all the tests to ./dist folder and so they get run twice.
