redux-api-middleware – iconv-loader warning August 15, 2016

I recently ran into an error using webpack with an electron based app I’m working on.  The error manifested from a webpack warning:

WARNING in [...base path removed...]~/encoding/lib/iconv-loader.js
Critical dependencies:
9:12-34 the request of a dependency is an expression
 @ [...base path removed...]~/encoding/lib/iconv-loader.js 9:12-34

How I ended up with this was:

• I produced an isomorphic web app with react, redux and redux-api-middleware (using a gulpfile to bundle it because that’s what the yeoman template used).
• I thought it would be great to share common code with an electron-based desktop app I was working on (using webpack because that’s what I’d chosen to use).
• I combined code and ran into the error.

To help resolve the issue I explored a few web pages and found this one that solved the problem (thanks Jim Pick!): https://github.com/andris9/encoding/issues/16

I added the following to my webpack.config.js:

 plugins: [
   ... other plugins listed here ...,
   new webpack.NormalModuleReplacementPlugin(
       /\/iconv-loader$/, 'node-noop'
   )
 ]
