Sass (Sass) Question

sass-loader not working with webpack + react + grommet

I'm trying to get started with webpack and Grommet working together. I'm following this tutorial: https://github.com/grommet/grommet-standalone but I'm getting the following error:

ERROR in ./src/app/index.js
Module not found: Error: Can't resolve 'grommet/scss/vanilla/index' in '/home/john/Development/Work/Utilities/react_practice/test_app/src/app'
@ ./src/app/index.js 31:0-37
@ multi library


Clearly it's looking for the scss file files in the source directory rather than node_modules - but I have no idea whats causing the error or how to fix it.

I'm using this sass loader: https://github.com/jtangelder/sass-loader

And I'm using webpack 2.10 because of this: http://stackoverflow.com/a/39608145/1596288

Additionally, these are my webpack.config.babel.js and index.js files:

import webpack from 'webpack';

module.exports = {
entry: {
library: './src/app/index.js',
},

output: {
library: 'bundle',
libraryTarget: 'umd',
filename: 'bundle.js',
path: './public/dist'
},

devServer : {
inline: true,
contentBase: './public',
port: 8100
},

module: {
loaders: [
{
test: /\.jsx?$/,
loader: 'babel-loader',
exclude: /node_modules/,
query: {
presets: ['es2015', 'react']
}
},

{
test: /\.scss$/,
loader: 'style!css!sass?outputStyle=compressed'
}
]
},

sassLoader: {
sourceMap: true,
includePaths: [
'./node_modules',
'./node_modules/grommet/node_modules'
]
}
}


and ...

import Header from 'grommet/components/Header';
import Title from 'grommet/components/Title';
import Box from 'grommet/components/Box';
import Search from 'grommet/components/Search';
import Menu from 'grommet/components/Menu';
import Anchor from 'grommet/components/Anchor';
import Actions from 'grommet/components/icons/base/Actions'

import 'grommet/scss/vanilla/index';

import React from 'react'
import { render } from 'react-dom'

const TesterComponent = () => (
<Header>
<Title>
Sample Title
</Title>

<Box flex={true}
justify='end'
direction='row'
responsive={false}>
<Search inline={true}
fill={true}
size='medium'
placeHolder='Search'
dropAlign={{"right": "right"}} />

<Menu icon={<Actions />}
dropAlign={{"right": "right"}}>
<Anchor href='#'
className='active'>
First
</Anchor>
<Anchor href='#'>
Second
</Anchor>
<Anchor href='#'>
Third
</Anchor>
</Menu>
</Box>
</Header>
)


render (
<TesterComponent />,
document.getElementById('root')
)

Managed to fix the issue by firstly modifiying my webpack.config.babel.js to the following:

import webpack from 'webpack';

module.exports = {
entry: {
    library: './src/app/index.js',
},

output: {
    library: 'bundle',
    libraryTarget: 'umd',
    filename: 'bundle.js',
    path: './public/dist'
},

devServer : {
    inline: true,
    contentBase: './public',
    port: 8100
},

resolve: {
    extensions: ['', '.js', '.scss', '.css']
},

module: {
    loaders: [
        {
            test: /\.jsx?$/,
            loader: 'babel-loader',
            exclude: /node_modules/,
            query: {
                presets: ['es2015', 'react']
            }
        },

        {
            test: /\.scss$/,
            loader: 'style-loader!css-loader!sass-loader?outputStyle=compressed'
        }
    ]
},

sassLoader: {
    includePaths: [
        './node_modules',
        './node_modules/grommet/node_modules'
    ]
}

}

Make sure you have the following libs installed too:

sudo npm install style-loader --save-dev
sudo npm install css-loader --save-dev
sudo npm install sass-loader --save-dev
