javascript - In vue webpack, how to determine whether to run dev or run build?

Question

I need to dynamically set the connection address of the server according to whether I am running dev or a built process, because I also need to set up backup servers and the like. It is very inconvenient to set up multiple places every time, but I don’t know how to get the running Is it dev or build? I figured it out. Thank you everyone~~~

You can set the environment in npm script, and then you can judge as mentioned above

"script": {
    "build": "cross-env NODE_ENV=production webpack --hide-modules --colors --progress --config=build/prod.conf.js",
}
