I am opening this issue in all 3 affected libraries (create-react-app facebook/create-react-app#4072 , html-webpack-plugin jantimon/html-webpack-plugin#858 , bluebird #1505)

Is this a bug report?

No, it is a deprecation warning


  1. node -v: 8.5.0

  2. npm -v: 5.6.0

  3. yarn --version (if you use Yarn): 1.3.2

  4. npm ls react-scripts (if you haven’t ejected): 1.1.1

  5. Operating system: MacOS High Sierra 10.13.3

  6. Browser and version (if relevant): Chrome 64

Steps to Reproduce

  1. create-react-app test
  2. cd test
  3. yarn start
  4. Open with Chrome 64+


Chrome 64 displays warnings (more annoyingly - even in production):
[Deprecation] chrome.loadTimes() is deprecated, instead use standardized API: nextHopProtocol in Navigation Timing 2.

It is related to:

I have searched which dependencies might use chrome.loadTimes() and found, that it might be bluebird:

└─┬ react-scripts@1.1.1
  └─┬ html-webpack-plugin@2.29.0
    └── bluebird@3.5.1 

Reproducible Demo

Open any create-react-app app, including the create-react-app template
or bluebird's documentation
