where is create-react-app webpack config and files?

If you want to find webpack files and configurations go to your package.json file and look for scripts You will find that scripts object is using a library react-scripts Now go to node_modules and look for react-scripts folder react-script-in-node-modules This react-scripts/scripts and react-scripts/config folder contains all the webpack configurations.

Make Discord bot send picture with message with NodeJS

ClientUser.sendMessage is deprecated, as is the file parameter in its options. You should be using Channel.send(message, options), with files as an array of strings or FileOptions. If you want to stick to your deprecated methods, ClientUser.sendFile might be something of interest to you, though I do recommend you move over to the stuff that’s more current.
