Thanks @ryota-murakami try adding the following to your package.json: "resolutions": {

},or "resolutions": {
"workbox-webpack-plugin": "6.2.0"
},They broke workbox-webpack-plugin v6.1.5 20 hours ago... Reading https://github.com/GoogleChrome/workbox/releases it seems like 6.2.0 that changed the build of files that the workbox-webpack-plugin depends on - workbox-webpack-plugin depends on workbox-build "^6.1.5" - Seems a bit fragile...

📣 We've released a new alpha version with the following changes:
In addition to these upgrades we've also changed the way we determine if we should use npm or Yarn when creating a new app. Previously this behaviour was non-deterministic. If someone had Yarn installed we would use Yarn and if they didn't we would use npm. Now we detect how you've invoked For example: # this will use npm
npx create-react-app my-app# both of these will use Yarn (depending which version you have installed)
yarn dlx create-react-app my-app
yarn create react-app my-app |

@ludofischer - Personally, I don't feel like these logs add any value for me during development, and would love for them to be suppressed somehow. Part of the reason I use CRA is so I don't have to deal with Webpack. I have always loved the clean CRA development output. If I see noise like this, my brain immediately thinks there's an error. |

I am writing a book about JavaScript build tools, so I am interested in the issues that people encounter when running webpack. I guess I need to tell how to reduce the webpack output messages!

@ludofischer I am aware of the configurations and have used Webpack for years. The issue here is that these messages appear when you run In this case, there is currently no way to disable these output messages since you can't modify the Webpack config out of the box with CRA. The configuration changes would have to be made somewhere within CRA, since it maintains the Webpack config under the hood. |
