I'm setting up webpack to my react project using yarn and this error appears:
ERROR in ./src/app.js 67:6 Module parse failed: Unexpected token (67:6) You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders ℹ ｢wdm｣: Failed to compile.

You are using unnecessary escape character: which is not required.
Replace test: '/\.(js|jsx)$/', with test: /\.js$|jsx/, it should work fine.
I replicated your issue in my machine and found the same which is resolved by the above fix.
hope this helps, happy coding!!!
The selected answer missing some details:
It should be test: /\.js|\.jsx$/
\: is an escape character in this case for .
|: is an Alternation / OR operand
$: is end of line
Hopefully this is useful for you.
add a .babelrc file to the same folder where your node_modules folder is, with the below content
{
"presets": ["@babel/preset-react"]
}
This error happened to me simply because the file was placed in the parent folder of the project (i.e. outside the project's folder).
Moving the file to the appropriate folder fixed it.
Put the code mentioned below in webpack file
mix.extend(
"graphql",
new (class {
dependencies() {
return ["graphql", "graphql-tag"];
}
webpackRules() {
return {
test: /\.(graphql|gql)$/,
exclude: /node_modules/,
loader: "graphql-tag/loader"
};
}
})()
);
mix.js("resources/js/app.js", "public/js").vue();
mix.graphql();
