Does not work with npm link

I’m not sure if this problem is coming from this loader or webpack or from node itself.

I’m developing a package having peerDependencies, so I’ve npm linked it to my application, that means that when I cd into my application’s node_modules I see a symlink my-package -> /real/path/to/my-package.

I’m using webpack2 and my resolve.modules looks like this:

resolve: {
    extensions: ['.js', '.jsx', '.coffee'],
    modules: [
      path.join(__dirname, "src"),
      path.join(__dirname, "node_modules"), // this was the 'fallback' option (for npm link-ed packages)
    ],

So npm link-ed packages should be correctly resolved.

This is the configuration for this loader:

{
    test: /\.js?$/,
    include: [
      path.resolve(__dirname, node_modules/my-package)
    ],
    loader: "source-map-loader",
    enforce: "pre"  
  }

but things don’t work.

Following all the options I’ve tried to pass to include:

• path.resolve(__dirname, node_modules/my-package) doesn’t work
• explicitly pass a relative path string ./node_modules/my-package: doesn’t work
• explicitly pass an absolute path string /real/path/to/my-package: works
• remove the include: works
• using fs.realpathSync('./node_modules/my-package'): works

By removing the include option it works but the loader will look everywhere, and as advised in the doc it’s not very efficient, but it works.

I have seen #14 that links to a webpack issue but it seems that old issue has been resolved in webpack2 (the one I’m using).

So I’m a bit confused about this issue, how I’m supposed to correctly setup the include path and from where exactly this issue is coming from?

I kinda of make it work with

var fs = require('fs');

// ...

{
    test: /\.js?$/,
    include: [
      // path.resolve doesn't work
      fs.realpathSync('./node_modules/my-package')
    ],
    loader: "source-map-loader",
    enforce: "pre"  // This means this is a Prealoader (comes before)
  },

and using devtool: "#inline-source-map",

@LeonardoGentile Are you sure “node_modules” is part of the path webpack is using to include your module?

Since your using npm link it’s likely webpack is using the resolved symlink instead of the link itself (ie: ./node_modules/my_package).

Could you try to remove the include option and use the main file of your package for the test regex ? For example: test: /my-package-main\.js/

Just to be sure.
