How to setup react properly

I have been following the react setup instructions on codecademy:

When I type in “npm run build” into the terminal I get this error:

I can’t seem to figure out how to get it to work.

Here is the link to my code on my github: https://github.com/throwkill999/react_demo

The error tells you that output.build is not a valid option. You probably meant to use output.path. There are other problems with how you concatenate __dirname in some places, because you need a leading / for them. But it’s better to use path.resolve for that.

Your config would look like this:

var path = require('path');
var HTMLWebpackPlugin = require('html-webpack-plugin');
var HTMLWebpackPluginConfig = new HTMLWebpackPlugin({
    template: path.resolve(__dirname, 'app/index.html'),
    filename: 'index.html',
    inject: 'body'
});

module.exports = {
    entry: path.resolve(__dirname, 'app/index.js'),
    module: {
        loaders: [
            {
                test: /.js$/,
                exclude: /node_modules/,
                loader: 'babel-loader'
            }
        ]
    },
    output: {
        filename: 'transformed.js',
        path: path.resolve(__dirname, 'build')
    },
    plugins: [HTMLWebpackPluginConfig]
};

Also in ./app/index.js you have a typo, it should be ./components/Apps (you forgot the s).
