I'm currently working on a upgrade from Webpack 1 to 2, and then to 3. Within this upgrade, I've adhered to the migration instructions as per the instructions for 1 => 2 and for 2 => 3.
The issue I'm having is that none of the installed packages within my node_modules seem to be getting resolved within my code inside client/app/bundles. The error I'm getting for all the node_modules are in the following structure:
ERROR in ./node_modules/alt/lib/store/StoreMixin.js || Module not found: Error: Can't resolve 'transmitter' in 'client/node_modules/alt/lib/store'
My theory is that somewhere I have a mismatch on the file-loader, expose-loader, or imports-loader versions since it makes sense that without the proper versions, the modules wouldn't get imported. I've ensured that all the module.rules have loaders that end in the -loader pattern. yarn install also succeeds without errors.
My dependencies and Webpack configurations are as follows:

I think the problem is that when you set the following option in your webpack.client.base.config.js:
resolve: {
modules: [
path.resolve('./app/bundles'),
],
extensions: ['.js', '.jsx'],
alias: aliases,
},
You override the default resolve modules option which is
resolve: { modules: ['node_modules'] }.
If you want webpack to find modules in your bundles folder aswell as your node modules folder, you should try something like the following:
resolve: {
modules: [
path.resolve('./app/bundles'),
'node_modules'
],
extensions: ['.js', '.jsx'],
alias: aliases,
},
EDIT: Also, you shouldn't look at webpack 1 docs if you're trying to upgrade to webpack 2. See the latest documentation instead.
