你是否是在说 create-react-app 创建的项目封装了 webpack 、Babel 、ESLint 这些工具。
如果是的话，你可以在初始化运行：
npm run eject
具体文档见：
https://create-react-app.dev/docs/available-scripts#npm-run-eject## npm run eject
Note: this is a one-way operation. Once you eject, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc.) into your project as dependencies in package.json. Technically, the distinction between dependencies and development dependencies is pretty arbitrary for front-end apps that produce static bundles.
In addition, it used to cause problems with some hosting platforms that didn't install development dependencies (and thus weren't able to build the project on the server or test it right before deployment). You are free to rearrange your dependencies in package.json as you see fit.
All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
