thanks for taking the time to look at this. Here's the issue at hand:
I am building a desktop application using ElectronJS and React. But every time that I load the project, I get these annoying warnings about sourcemaps in the console:
I know that the manual solution is to go into the dev tool settings every time I run the project and uncheck these boxes:
However, is there a way to configure this so I don't have to do this each time I load the project? It's very cumbersome and annoying.
In case you need it, here are my package.json scripts (I use "app" to run it)
"scripts": {
"app": "concurrently \"cross-env BROWSER=none npm start\" \"wait-on http://localhost:3000 && electron .\" \"npm run watch-css\"",
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"build-css": "node-sass ./src/css/sass_css/ -o ./src/css/vanilla_css/",
"watch-css": "nodemon -e scss -x \"npm run build-css\"",
"eject": "react-scripts eject"
},
Yes I used create-react-app. Added my webpack config:
#!/usr/bin/env node

stdio: "inherit",

});
executedCommand.on("error", error => {
reject(error);
});
executedCommand.on("exit", code => {
if (code === 0) {
resolve();
} else {
reject();
}
});
});
