命令行 arguments 到纱线启动

Question

I have created a react app with "start": "react-scripts start" in package.json. I run it using yarn start. However, I want to pass an argument from command line eg yarn start -- test=hello and access it it in index.js .

I tried to access it using process.argvs but it is not there. How should I pass command line arguments to yarn start ?

Answer 1

I don't think that react-scripts take command line arguments.

If you want to pass arguments to node you will have to eject cra, then you will be able to pass arguments to node.
