How to identify source of React.createClass warning? React v15.6

Question

How can I identify the dependency that is causing the warning?

Warning: Accessing createClass via the main React package is deprecated, and will be removed in React v16.0....

I understand the changes that are coming with React v16.0. I want to help the dependency resolve the warnings but I don't know who needs help.

Package.json

"dependencies": {
    "autosuggest-highlight": "^3.1.0",
    "material-ui": "next",
    "material-ui-icons": "^1.0.0-alpha.19",
    "nuka-carousel": "^2.2.1",
    "react": "^15.6.1",
    "react-autosuggest": "^9.3.2",
    "react-dom": "^15.6.1",
    "react-helmet": "^5.1.3",
    "react-router-dom": "^4.1.2",
    "react-tap-event-plugin": "^2.0.1",
    "typeface-roboto": "^0.0.35"
  },
  "devDependencies": {
    "enzyme": "^2.9.1",
    "jest-enzyme": "^3.6.1",
    "react-scripts": "^1.0.10",
    "react-test-renderer": "^15.6.1"
  },

Answer 1

1. You see next to the warning in the console the line of it. Jump to that line in the chrome-debugger, (just click on it)
2. Set a break-point there
3. Reload the page, and you'll get there
4. Next, in the debugger there is the stack tab, open it, to see all the functions path to that line.. You should be able to identify the problematic source
