Unable to implement webpack in project with node-red - node.js

Question

I am trying to implement webpack in my project which contains node-red. However, I keep getting the following warning. Please suggest how to solve this error -
WARNING in ./node_modules/node-red/red/runtime/storage/localfilesystem/projects/git/node-red-ask-pass.sh 1:26
Module parse failed: Unexpected token (1:26)
You may need an appropriate loader to handle this file type.
> "$NODE_RED_GIT_NODE_PATH" "$NODE_RED_GIT_ASKPASS_PATH" "$NODE_RED_GIT_SOCK_PATH" $#

# ./node_modules/node-red/red/runtime/storage sync ^\.\/.*$ ./localfilesystem/projects/git/node-red-ask-pass.sh
# ./node_modules/node-red/red/runtime/storage/index.js
# ./node_modules/node-red/red/runtime/index.js
# ./app.js
My webpack.config.js is -
const path = require('path');
var nodeExternals = require('webpack-node-externals');
module.exports = {
target: 'node',
externals: [nodeExternals()],
entry: './app.js',
output: {
path: path.resolve(__dirname, './output'),
filename: 'bundle.js'
},
resolve: {
extensions: ['.js','.json', '.sh'],
modules: [
'node_modules'
],
},
module: {
rules: [
{
test:/\.css$/,
use:['style-loader','css-loader']
},
{
test: /\.coffee$/,
use: [ 'coffee-loader' ]
}
]
}
};

For Webpack, every file is a .js. In order to handle other extensions, like .css or .sh, you're supposed to use a loader, like you did with css-loader, that will tranform CSS rules into JS.
The issue you're facing is that you've got an import chain (./app.js -> .../index.js -> .../index.js -> .../node-red-ask-pass.sh), so Webpack will, at some point, will import a .sh file, but will throw an error because shell code is obviousouly invalid JavaScript. that is why you're seeing the error that you have.
By the way, I couldn't reproduce the issue you're facing:
npm init -y
npm i node-red
# ./node_modules/node-red/red is not a directory
So it was probably a node-red bug. Update the package to the latest version.
