Bundle sha3/binary modules with Webpack - node.js

Question

Webpack warns when I bundle my source as it can't resolve the 'sha3' module.
$ npm run build
WARNING in ./~/keccakjs/index.js
Module not found: Error: Can't resolve 'sha3' in '<PROJ>\node_modules\keccakjs'
# ./~/keccakjs/index.js 2:19-34
# ./~/<lib>/index.js
# ./lib/<file>.js
Reason being the sha3 library has no js files.
Creating library <proj>\node_modules\sha3\build\Release\sha3.lib and object <proj>\node_modules\sha3\build\Release\sha3.exp
I am able to run require('sha3') in my project, however webpack cannot resolve it.
I looked at the docs here, regarding how webpack resolves libs.
Could someone point me to how I can include sha3 in/with my bundle.
My Webpack config:
module.exports = {
target: 'node',
entry: "./<lib>.js",
devtool: "source-map",
node: {
__dirname: false,
__filename: false,
},
output: {
path: "./dist",
filename: "<lib>.min.js"
},
plugins: [
new webpack.optimize.OccurrenceOrderPlugin(),
new webpack.DefinePlugin({
'process.env.NODE_ENV': JSON.stringify('production')
})
]
}

Answer 1

What actually ended up working for me was:
resolve: {
alias: {
sha3: path.join(__dirname,'node_modules/sha3/build/Release/sha3.node')
},
},
module: {
rules: [
{test: /\.node$/, use: 'node-loader'},
]
},
That way I told it which file to import, when it wasn't able to resolve sha3. And the node-loader packages in the .node file!

Try using the binary loader from webpack from here. Then you can:
1) Define loaders in your WebPack config:
module.exports = {
target: 'node',
entry: "./<lib>.js",
devtool: "source-map",
node: {
__dirname: false,
__filename: false,
},
output: {
path: "./dist",
filename: "<lib>.min.js"
},
plugins: [
new webpack.optimize.OccurrenceOrderPlugin(),
new webpack.DefinePlugin({
'process.env.NODE_ENV': JSON.stringify('production')
})
],
module: {
loaders: [
{ test: /sha3$/, loader: 'binary' }
]
}
}
2) Use the loader directly in your import:
require('binary!sha3');
